'87 TII LT-8s Success!
Finished wiring everything up last night and got the fuel system all hooked back up last night. Charged up the battery, turned the key and she fired up!! Ran like crap until I figured out I had forgotten to hook the vacuum line up to the MT, oops. ;-) She idles easily, but runs WAY rich! Gonna hook up the LM-1 and the handcontroller this weekend for some tuning. Wish me luck!

Thanks guys!
TII '87 - I hooked both the CAS and coil MT harness right into the stock harness that runs under the dash. I can get you the colors tonight if you'd like as I still have yet to clean everything up and put the carpet back down. ;-)

Going to do a little tuning tonight. Anyone have any thoughts on wiring the wastegate open, and tuning the vacuum side first as opposed to just going all out?

What I have heard ...spend a day on the vacuum side and be **** about it. This way you'll be fine to drive the car around comfortably as long as you need before boosting.
If it were me, I'd spend as long as it needed to get everything severely perfect.

Awlright, well we didn't get any tuning done. Why is it that when you get a bunch of RX-7 owners together, we don't get anything done with the cars? Probably has to do with all the beer that was consumed. :-P
I did get the wideband in and the car gassed up. She drives pretty good in vacuum (pig rich) and I couldn't resist getting some boost on, saw 11's all the way across. So today (maybe) I'll get some vacuum tuning done. Should probably hook up an air filter. ;-)

Haven't we ALL heard this
Yeah, that car sure does run great for just putting in a base map!
I was rather impressed...I just got done installing a E6K in my TII and it was cool getting to see the Microtech. I still can't get over how SMALL the Microtech is. Sure makes the Haltech seem huge!
Yeah, RX-7 guys hanging out....nothing does get done...cept lots of talking about 'em

Hey James! Yeah, it sure was fun getting to hang out and cruise with you guys. Next time, I'm coming to Laredo!
The MT sure is smaller than your E6K (especially the harness) but that E6K also has a metric butt-ton more features. So it's kind of a tradeoff.I still haven't gotten any tuning done cause I have no way to hook up my air filter yet. :-(

I wired mines up according to the harness plug, and no spark, i look more closely at the cas and the colors change from the cas to the plug!

I was rather surprised with the basemap on the MT. It truely felt like plug n play. The instructions were straight up, and the diagram was awesome. The car started right up and drove beautifully with the basemap. I still have that spark problem though.

Ryde Or Die - I don't think the install was too hard. All the wires are labeled and easy to distinguish. I highly recommend keeping the stock harness and hacking it up. The MT harness wasn't long enough to reach the sensors and injectors. I stripped my stock harness down, removed the unnecessary emission equipment wires and spliced it onto the MT harness. After that was done I wrapped the whole thing up in some rubber self adhesive tape that we use to weatherproof antenna connectors down here. With the complete harness installed in my car, the stock harness goes from the engine to just past the passengers side shock tower, where it splices into the MT harness. I think anyone with basic electronics knowledge could easily pull this off....just go slow and check over your work multiple times.
Rex - Yes, the red and green are the only ones that technically matter. They are red and green on the CAS and the harness. I hooked up the other two grounds because after looking at the FSM, it looks like they ground inside the CAS. <shrug> Piece of mind.
And I agree that the basemap is nice! Very drivable. I'm really looking forward to getting it dialed in though.

but what did you do for the 12V ignition??? the stock harness bring 12V ignition to the coils, is it ok the leave it as is???
For the pink wire ( 12V ignition trigger ) where did you hook it up??
Thanks a lot for the helpful tips.

I took my pink wire for "ignition on" of the leading coil- harness which was a thick black-white (I think) wire but I'm not sure about the colours. Just turn ignition on and check with voltmeter.
The MT harness is made for RHD cars, so I have removed the stock engine harness from my car and spliced all the wires to stock connectors. The harness was long enough for my car (It's RHD FC3S from Japan), but I can imagine, that you will get in trouble reaching the coils on the LHD car with MT harness.
From my first install I have missed the CAS wires, as I have used the wires (red and green) from the loom not from CAS. Changing this to CAS makes engine starts fine with no probs.
Base map is rich, which is the safest way to start and run. I prefer to rich that to lean.
Knock detection is just one thing I'm missing on MT making tuning very hard as they are no or just few usable aftermarket knock detectors out there. I'm looking for one which was approved on Rotary?s, so if anybody can recommend a trusted and approved knock detection device I would appreciate any advice on this.

Yes, the coil's power is perfect for the MT as it has constant 12 even through cranking.

TII '87 - Yep, the grey wires are spliced into the stock harness. For the +12v and ignition I ran a heavy gauge wire straight from the battery to the MT, to feed the fuel pump, injectors and MT. For IGN I spliced a seperate wire off from the hot +12v and put a relay on it that is turned on by the ignition switch.
I looked at the stock harness with a DVM for a 12v ignition source and coulding' find it! :-P Didn't see it in the FSM drawings either, so I just ran my own.

White---- Yellow on the CAS thats kinda strange mine was yellow for yellow on my microtech. I have not finished mine yet but we just did one a few weeks ago and what about hooking up you windsheild wipers??? any ideas on that. I still have a harness on the floor board that does nothing im guessing?? and 2 clips behind the glove box that look like they run some heater motors or something any input?

I've removed the part of my stock ECU harness that has the wires for the wipers in it and someday I'll wire them back up. :-P Not worried about the dashboard water temp sensor as I already have an aftermarket gauge for water temp.
