haha, wow, I'm dumb... it doesn't even say you need a turbo.

 

It seems almost all of us have a cardomain website.. Well i'll see yall around.. (waiting for ACT clutch to come in)

 

I have a turbo to cat pipe.

 

would anyone liek to offer me some manual driving lessons

 

buy me lunch and I'll teach on the del sol before I sell it!

and myk: the s5tii does interest me tho..so i'll IM you tonight if i can about it.

 

^ haha awesome, what you want for lunch? ;] im in the silver spring area, right by college park.

 

when the next meet

 

May 15 - https://www.rx7club.com/ne-rx-7-forum-30/fuddruckers-meet-may-15th-416213/

 

guess i'll never meet the rest of the guys then cuz the meets are ALWAYS on dates i cant make. oh well.

 

That's waayy more than I need... haha...

Julian is going to be soldering his megasquirt tonight (more of it anyway) if anyone wants to come by. He's getting pretty good at soldering now.

I specified "learn to solder wires" b/c that's what falnfenix needed to do... and it's easier anyway.

 

Akuma... just request off.. we always put it up at least 2-3 weeks in advance

 

who said i was working...im just not free cuz i got stuff to do.

and once again...i dont go scanning around the whole site trying to find stuff cuz i dont have an rx-7.

 

oh yeah, jason's 'vert is running a lot better now. Not perfect yet, but we're getting it there... the fuel maps are almost dialed in where jason wants them just a little more tuning at really low revs (like idle to maybe 2000) and high vacuum. Jason seems to be able to hit parts of the map that almost nobody else ever hits. Like 800 rpms and low vacuum (high load). I have to hand-tune that because at low revs the megasquirt can't respond fast enough to the afr to do anything about it (plus I have closed-loop only turning on above 1000 rpms).

At cruise and high load, the engine pulls pretty nice (could probably use more ignition advance, but we're playing it safe until we have an EGT gauge). Deceleration fuel cut works nicely... there are spots in the datalogs like 15 seconds long or longer where there was no fuel being injected on engine braking... that should save some gas.

I'm going to tune the accel enrichments tonight to get back the throttle response, and then it should be daily drivable from 0 throttle to full throttle up to 4000 rpms. We need to get the aux ports and VDI working before tuning any higher (I'm fairly sure actuating the aux ports or VDI will change the volumetric efficiency of the engine a fairly large amount, so there's no point in tuning without them)

I've also ordered the circuitry I need to switch back over to the stock rotary ignition... leading only for now, and then when the code is good enough, I'll add trailing back... then the stock dash-board tach will start working again

There are a few mechanical problems still though, like the throttle linkage seems to be getting stuck at 2% throttle occasionally, and the alternator can't decide whether it wants to work or not, so those are affecting the tuning a little.

 

heh...the notorious alternator on that car.

 

Jason has an FD alternator I'm pretty sure... it's probably just a wiring issue

 

nope, it's a remanufactured FC alternator I believe. He said that problems with that alternator going from 13.9ish volts to 12.5 volts intermittantly are normal, he was seeing this behavior with the stock wiring. Every time he said something about the alternator on this car, he said he's GOING to get an FD alternator for it.

 

yay, it's almost time to start working on my car . and don't worry, my car doesn't have aux ports or VDI, cause it's not dumb

edit: well I have a l337 FD alternator already, cause my car is awesome

 

no, your car just has a turbo, which means I'm not doing ANYTHING to it till I read that turbo book of jason's... and you need to get your Innovate LC-1 or techedge wideband.

 

yay, that means it's almost time to start thinking about maybe working on my car

 

is jason considering upgrading to the MS-II ? would that solve the MS not responding fast enough?

 

It would if the cpu speed was the problem. That's not the problem however, I just need to tune the enrichments .... I need to set the Throttle Position Sensor threshold just above where it starts randomly triggering so that the megasquirt starts enriching fuel as soon as the gas is tapped. For example, I had it set up last night so that it takes a voltage change on the TPS of 2 v/s to actuate accel enrichments. A value of .7 v/s is more appropriate.

The MS-II isn't going to be available again until July or August anyway, and there are plenty of people running the firmware I'm running on rotary engines... so it's a tuning issue, not a hardware-speed issue.

All that said, by July/Aug when the ms2 comes out, we MIGHT switch... we won't need to, but it's that "it's working right so I need to break it" factor

 

anyone that posts with us have a first gen? I found 2 in the bone yard in laurel on Friday. One was a 85 in great shape and one was a 79 with a alomst perfect tan interior. Anyways I grabbed the speedometer guage cluster, center storage/arm rest column, some passanger seat lever that lets the driver put the seat forward, and 2 dash switch housings for defrost and a few other things. I am going to carbon these in probably 2x2 5.7 oz twill if anyone wants dibs. Also I wont bother making these in the future due to costs over gain and the fact that their is 2 different 1st gen interiors just wouldn't make it worth it. Drop me a pm if you need something made.

Where in Laurel did you see those cars. I need a few exterior bits from the '85!

 

it was at crazy rays. The car was red and the interior was grey. Motor was complete with carb. Very clean car. Its in the import section all the way in the back of the yard. You better get what you need soon. Rays crushes cars after 3 months and I am not sure how long it has been their.

 

Thanks I'll be there tomorrow!
