Re: Porsche 944 Megasquirt conversion
Also, Tom came over again last night and we got the timing belt cover put back, zip tied some wiring and took it for the first test drive -- just down my street and the next street over to the cul-de-sac. I'm sure I looked pretty hillbilly to the woman and her daughter near the cul-de-sac with no ho...

Re: Porsche 944 Megasquirt conversion
I discovered it by posting a thread on the msextra.com/forums -- in TunerStudio, you can take a 'tooth log' which shows the trigger pattern seen by the CPU in detail. I don't know how to analzye/interpret those logs, but there are guys on the forum who know and help. So I posted a bunch of logs, mad...

Re: Porsche 944 Megasquirt conversion
This setting. Which, ironically, is what I use on my Chevelle and Malibu, but its a different sensor, and the default is to use Rising Edge. Even when my cars were set wrong, they still started up and ran. I mean, the Chevelle ran *great* with the wrong setting until 5100 RPM, when it had a hard cut...

Re: Porsche 944 Megasquirt conversion
So I haven't posted too many updates, because the car **still** doesnt run. The signal from the factory crankshaft position sensor would drop out to 0 while cranking. I tried reversing polarity, adding a 10k resistor, tried adjusting these 'pots' on the mainboard. Nothing was helping, the Megasquirt...

Re: Porsche 944 Megasquirt conversion
So I got the injectors swapped during my lunch hour today. I removed the low-impedance 28lb injectors and installed high-impedance 30lb injectors. Still no start. Not even a cough, which was puzzling. Further troubleshooting revealed that the fuel lines were hooked up backwards. No wonder I wasn't g...

Re: Porsche 944 Megasquirt conversion
It's been a while since I posted an update, but a lot of progress has been made despire losing almost a week to being sick and other assorted ailments. However, a lot has gotten done. I'm using the S2's factory 60-2 crank sensor. I'm seeing RPM signal when cranking the engine. I need to verify TDC a...

Re: register new number
Sorry I'm late on this Matt... just give me a username and password to use (priv message, email, txt, whatever) and I'll set it up.

Re: 1987 Corvette Z52
I'm pretty sure the rear toe-in is adjustable -- there's a spec for it, at least. You might be able to fix it without losing your lowered stance.

Re: Porsche 944 Megasquirt conversion
I got some progress under my belt here the past couple days. Starting with a cardboard template, I made a mounting plate from some aluminum (courtesy CutNPaste). I mounted the MS3X on some MSD rubber isolation mounts. I got fancy with the fuse panel and relays, using rivet nuts to mount them. No sel...

Re: Porsche 944 Megasquirt conversion
The intake manifold is unusually large, I think.

Porsche 944 Megasquirt conversion
Scott brought the Fickle Bitch Racing Porsche 944 over for a Megasquirt conversion today. The car was upgraded to a 3.0L S2 engine over the winter, which should be good for +60hp over the previous engine. Since I'm one of the drivers for Mid-Ohio in September, I have a very vested interest, and also...

Re: 2023 Kuhnle Motorsports Park Wednesday nights
Another fun Wednesday is in the books! I took the Chevelle out for, I think, the 6th time this season. I'm trying to make up for all the times I couldn't take it last year. It didn't feel like good air, and the DA was around 2500 when we got there, but I still put down a 12.39 @ 108 for my first pas...

Re: 1979 Malibu
Woohoo, it's back home! I picked it up on Thursday evening, was gone all day Friday, and started continuing with work on Saturday. I had to replace a few headers bolts that must've backed at at Dragway 42. I moved the Fan Relay, it was too close to the turbo. I'm waiting for a few more parts to fini...
