I don't have the Pins/Connectors from Will yet. He's shipping them out this week. ;) Notice how the ethernet cable comes from one of the 4x connectors.

Harumph! I've got like a dozen sets of 1 and 2 keyway Motec/Haltech/Emtron/etc connectors and a couple spools of pins laying around, Mouser is your friend. All I hear are excuses!

Fun Fact: Ethernet only needs a twisted pair to work.

Wouldnt you need 2 twisted pair for tx/rx?
100BASE-T1 and 1000BASE-T1 both run over a single twisted pair. As far as I know it's only found in automotive applications but is different from standard CAN as it's full duplex. I have no idea if the COMs on ethernet based ECU communications is xxxBASE-T or xxxxBASE-T1. Here ends the useless nerd factoid of the day. |

What he said lol. So right now most stuff is 100 Base T but companies are working on 1000 Base T. Basically at this point cable and connector technology is outpacing chip technology which is wild.
Sorry to keep turning this thread into a networking shitshow, and not to be a contrarian but they've been running 1000Base-T for years, it's just gigabit ethernet (1Gbit/s - 99Gbit/s) and is well standardized. What is up in the air is terabit (100Gbit/s - to infinity and beyond) ethernet that is faster than 400Gbit/S but that should be adopted in the next couple years. Back to the car shit! |
:drool1:
Me everytime I come and have a look here. I wrench a little bit, but this topic is way out of my league, I can just admire and drink my coffee while I pretend I am working. |

Me everytime I come and have a look here. I wrench a little bit, but this topic is way out of my league, I can just admire and drink my coffee while I pretend I am working. As of 12/10/2018 I'm working alongside Quicktime and Mantic Clutches to re-develop a bitchin' T56 Transmission Swap that's totally bolt-up. Grannis Motorsports is doing the final test fit stuff on their rig and I'll be getting the first setup of Twin Disc Mantic 9000 Series Full-Faced Organic Clutches and Quicktime SFI Certified v.2 Bellhousing. It's been a hell of a ride and I promise y'all I'm still pursuing greatness here... Here's how I explained my situation to a buddy the other day: Him: the internet is a lie Me: I'd say it's more of whatever you need it to be. For most people, that's answering rooted questions, keeping up with the times, and fitting in where they feel they don't belong. So instead of using your mind and logic, you finance shit to make yourself feel wanted. Consumer society. I need to run an untested ECU platform on a rotary engine and build my own wiring harness to teach myself a valuable lesson. Has nothing to do with WHAT I'm buying, but the openness it grants me when allowing me to grow new skill sets. That's why the build duration doesn't matter... Never has. willing to put your money where your mouth is Me: I'm just in-tune with what money is... You can buy safety, comfort, pleasure, release, etc. At the end of the day, it's better spent than saved due to our market and inflation. I use money to educate myself. Everything else can wait. |
So my Connector and Pin set is on it's way this week along with a master kit of Deutsch DT, DTM, and DTP connectors. No excuse as to not being able to make a bitchin' harness now! :D
|
The ethernet cable will be a 6ft Cat6E that I cut up and pin to a solid terminal DTM with strain relief loops and DR-25 heatshrink. :D
Ohhh, I love just being productive and off the radar. Hope y'all haven't forgotten about me. |
A short length of Cat 6 would be an awesome sensor wiring refactor for my project.
|
I have spent some time on your thread from searches but I haven't had time to peruse it all till today, it was a slow day at work. Nice long term project, glad your getting to do it the way you want. Nice to see the custom fab work, please keep up the posts.

Would your FC front subframe system put the wheels centered in the wells, or would they be an inch forward like the typical bolt-in? I read through this thread over the last couple days, but missed how you fixed that. I mean, in one picture you show how close the tire is to the front of wheel opening, and a few posts later they look centered.
Okay I admit it - I mostly just skimmed through looking at pictures. But I'd love to upgrade the front suspension and steering, but don't want to cut the fenders to do it. |
Sorry, dumb post. Of course yours would put it in the right place.

Give me an idea of your usage for the vehicle, power output, rear end choice that you've selected, estimated tire/wheel size, etc, and we'll go from there. Not sure if you just want suspension geometry figures or a "here are my fuckups" run-through, but I'm down to help as much as I can. |

Not sure if you just want suspension geometry figures or a "here are my fuckups" run-through, but I'm down to help as much as I can. The general idea is I want this car to be everything I remember my 79 Rx7 from high school being plus those things I wanted it to be back in the day but couldn't either afford or didn't know how to make it happen. Now memory is a tricky thing. I remember that car having great paint, great sound system, great handling and great brakes. Back in the day if I had the ability I would have given it the power of a V8 and a more muscular look of a widebody to go along with the whale tail. I currently have a 79 limited so I know what the reality is, the car is fun to drive, simple and sporty, a real throwback to a simple and fun car. But its not as fast as I remember, or handle the way I remember, brakes are not enough, and the stereo, I haven't actually listened to a cassette in a while but once I heard one in the 79 I couldn't believe... well it wasn't what I remembered. As far as use the car will be a driver. It really wont see any track time but spirited road driving, more on the sports car side of a GT car. So the plan. 1) The car already has a wide body kit. The paint is crappy so it will bet completely stripped and straightened before repaint, 2) V8 conversion. 350 hp and 350-400 ft-lbs torque 3) FC front suspension swap 4) Rear end, I have no idea, but given the FC has a lower roll center it will need to lower the roll center also and be able to handle the power and torque of the V8 5) For wheels and tires, my plan is 17x8 front and 17x9 rear, with 245/45 and 275/40, the biggest issue with these is the overall diameter. The 25.7 inch diameter might be too wide. The fender opening is 26 inches so it might just be to wide. The fallback size would be 215/45 and 245/40, since they are 24.7 inches tall. Both can fit on 8 and 9" rims. 6) I have ordered FC coilovers with 450 lb/inch springs for the front. I don't have the extensive plan you did starting. I am really figuring out as I go and I realize much of this is an experiment and things will change and be redone as I go. So I am always open to input from others who have been there before me. |

Just kind of a general observation. It can make good AV wire if you're doing custom in-wall wiring. Expanding on that notion, since it has several conductors bundled together nicely and they'll take a reasonable amount of current, it seems like a pretty decent way to wire groups of gauge senders or relay signals in general. The connections are nice and secure and easy to separate, too, when you need to. Plus the components for making/connecting cables are very easy and cheap to get.
https://www.mouser.com/Wire-Cable/Ca...kreu?P=1yxufhe I'll let your mind wander on that. Jeez, if I didn't just pick up all this m22759/32, I wouldn't hesitate on that for a minute. |
She's home!
Now time for interior, sound deadening, clubsport spec wiring, etc. Time to get rowdy! |
My fabricator and I came to an agreement and essentially we had to halt the production of my other car so that both of our businesses could grow more effectively. So, I cleared the car out of his shop and jump-started my ass to cleaning up my house/garage full of miscellaneous parts for Integra, Civic, and Rx7.
https://cimg1.ibsrv.net/gimg/honda-t...1e3c5c364d.png I'm in the business of chassis setup and engine calibration now, so here's one of the cars I setup this weekend. Ryan Raduechel's 88mm Chinese Turbo 5.3L LM7 Truck Motor crammed into a 1st Gen Miata. That turbo really gives up over 6.5k where the excessive backpressure is apparent. You get what you pay for on these turbos... $500 turbo and 720whp/700wtq is pretty sick though. I left timing pretty conservative and let her eat. As you can tell, it's buttery smooth (no correction factor either) and the cam to injection firing angle tuning, coil tuning, fueling, etc are all dead on to where I want them now. https://cimg7.ibsrv.net/gimg/honda-t...255dcd3e69.png Ohh, and I also managed to get my first Visio Professional Wiring diagram together in a couple hours. This is going to be for the ECU to Engine Bay of my 1st Gen Mazda Rx7. The body harnesses are also changing, and there's also another portion of the ECU harness that goes center of car and rearward of car. This is just firewall bulkhead to engine stuff. https://cimg3.ibsrv.net/gimg/honda-t...ab4589e06e.png |
That’s awesome that you get to get paid for doing something you have so much passion for. Good luck but I doubt you will be needing it seeing how much work you put into it though it never hurts.

Been following this thread for a while figured i would chime in :D absolutely stellar work is going into this car mate
the network cable is a good use for sensors too ! i took at look at your videos about using the standard FD butterflies; as most people tend to remove them - i'm of the belief that mazda would of spent ages working on these things. Plus you can see their devotion when you take apart an RX8 inlet manifold and how complex that is for the runner lengths etc.. I'm lucky to have found a tuner and a mechanic whom agree as they have worked on mercs where the runner lengths matter and how much volume is sent as the revs go up. We have been experimenting with the standard FD solenoid, an air tank, drive by wire throttle (rx8), electric pedal sensor all running off a LINK ecu Fury G4+ already it appears to assist with the cold start (quite an issue with pure e85) hoping it will provide more torque lower in the rev range increase drive-ability Soon to be testing all this on the dyno :) im wondering if you had any tests of your own? or threads you can share? https://photos.app.goo.gl/PMDU2DXBaooWJGkP8 https://cimg8.ibsrv.net/gimg/www.rx7...7db966a8ea.jpg |

It should work better in practice on a rotary than an inline-4, which I based my vacuum pod/solenoid equipment from (H23A VTEC motor to be exact). Not sure if you were ever a Honda guy, but the large crossover induction noise that people commonly refer to as VTEC KICKIN IN, is actually these "IABs (Intake Air Bypass) which dumps open around 250-400 RPM before VTEC crossover. I'm leaving my main job here in California and focusing on building a new race motor for my daily driver (1992 Honda Civic EG Hatchback). Once that's completed, I'm picking up an ABCD Harness from Emtron and wiring the car up. The final fabrication is going to have to wait until the interior, electrical, and plumbing is dialed. That's where I'll focus the rest of my year. Cheers mate, -Ryan |

Debating now on picking up the ECUMaster PMU16 to replace my factory fusebox too... Already balls deep, what's the worst that can happen? |
|
https://cimg2.ibsrv.net/gimg/www.rx7...5e10dcf4fc.png
https://cimg4.ibsrv.net/gimg/www.rx7...0fe8a6ebf7.png Getting started on the 2x ECUMaster PMU16s to CANBus through to the Emtron KV8. Not bad for the first day at it! |
Here's the update for a few more hours of work...
https://cimg5.ibsrv.net/gimg/www.rx7...e822cf3992.png PMU #1 https://cimg6.ibsrv.net/gimg/www.rx7...cec6f66d9b.png PMU #2 Plenty more to do still, but this is a good start. |
Looks like you're getting down to the last few planned outputs. I don't see flip up motor control, I had to monkey around with shared supply between hi and motor as well as low and motor using funky faux hysteresis settings and some cobbled together circuits/diodes on some PM15 profiles I built.
|
Nice!
In addition to headlight retractor motors, if you want the PMU to handle cruise control inputs for the Emtron, you'll need 4 more inputs on that list for: - clutch pedal switch - cruise set - cruise cancel - cruise resume I assume brake light switch input is from the brake pedal (also needed for cruise). Also, windshield washer? Door switches (for automated interior lights and security)? I realise it's still a work in progress, but thought I'd add in case it helped. Those inputs fill up fast! |
Hmm... Time to tear down and start finish welding.

Trying to see the positives... First day clearing out the car since it left fabrication and I'm seeing damages everywhere. �� Well, I guess I get to rewire and upholster everything out of necessity now... Fuck my life. Damaged Dash, Electrical, HVAC, Windshield, etc. So far there's only minimal rust. Only one approach left; move forward and keep hustling. https://cimg9.ibsrv.net/gimg/www.rx7...64a53c8bea.png https://cimg1.ibsrv.net/gimg/www.rx7...f48058c5c5.png https://cimg2.ibsrv.net/gimg/www.rx7...919185e9af.png https://cimg3.ibsrv.net/gimg/www.rx7...e6637d8680.png Thanks guys for the clarification on the PMU configuration. It turns out the Cruise Control should be through the KV8, as well as clutch pedal, cruise set, cruise up, cruise down. Totally forgot the windshield washer. Door Switch are a great addition for security! |

https://cimg3.ibsrv.net/gimg/www.rx7...83808597d2.png I think this is more OEM-like. I was making things too complex with splitting up circuits for no reason. ACC ON START Various Independent Analog Inputs/Outputs ECU to PMU #2 CAN Started Next Items to Tackle: Inter-connectivity between ECU, PMU #1 and PMU #2 with CAN inputs and outputs. One of these days I'll get my head out of my ass enough to move back to a "normal" schedule. Hopefully this is a move in the right direction with the programming side of things. Ohh, and since some of you asked... the OEM Harness got torched by my previous fabricator, FFR Fabrication due to negligence. https://cimg7.ibsrv.net/gimg/www.rx7...6fd42fedc0.png https://cimg3.ibsrv.net/gimg/www.rx7...a6bd28c4d0.png https://cimg6.ibsrv.net/gimg/www.rx7...5f65e08dbf.png https://cimg2.ibsrv.net/gimg/www.rx7...036a165664.png https://cimg4.ibsrv.net/gimg/www.rx7...2eefa7f5a7.png |
Uhhh. The fuck? Where on earth was he welding to not be hit by the "Better throw a welding blanket over that" fairy with a baseball bat?
On a side note, and you may think this is stupid, I always write a user story before I design/architect functional and back end requirements for projects. It helps me out with A.) analysis paralysis, B.) over complication, and C.) over simplification. I've caught quite a few things with a few paragraphs that start with "I walk up to the car and..." Think Agile development applied to cars. |
This last weekend I was out at Thunderhill setting up drift cars for both suspension and engine tuning. Ran into issues on everything with mechanical failures, that cut our fun short, but the company, as always, was great.
https://cimg4.ibsrv.net/gimg/www.rx7...dace7c174d.png Started to do my 5th and 6th Injectors, UIM Modifications, and a bunch of small tidying up throughout the engine bay. I realized that Nylon e85 Hose via ImprovedRacing is really not ideal for my usage here, so I ordered up a massive amount of stuff for the higher temp required items (turbo, oil coolers, etc). https://cimg4.ibsrv.net/gimg/www.rx7...d83241d8d3.png https://cimg5.ibsrv.net/gimg/www.rx7...f3d6fb4b9c.png So most of these lines are planned to be redone and shortened for their tasks.

Once the transmission is mounted, the engine tilts back quite a bit here. |
https://cimg4.ibsrv.net/gimg/www.rx7...134a0a9eca.png
Wastegates are set. 5psi Springs, -6AN Water Fittings, -4AN Vacuum Fittings, and clocked to perfection. https://cimg5.ibsrv.net/gimg/www.rx7...d81008f0fe.png Made a bunch of new lines, routed coolant for wastegates and turbo (on paper), and slowly tidying up the engine bay as I see fit. |
Nice choice on the Vibrant vacuum manifold, I put one on each of my vehicles.
Are you keeping the A/C? I noticed one of the lines is still in there. |
