99-00 Ms2 start up problems.
Hey guys, so I've been doing a lot of researching (I suck with google, so please by all means prove me wrong), and cannot find a single thing even close to what I have going on.
I have a fully PnP Ms2, no wiring/soldering required. Haven't been able to get it to run, at all, until tonight.
I have followed all installation instructions to a point, and even started from ground zero a dozen times over just to be sure everything was correct. MAF unplugged, speed density vacuum line hooked up, timing adjusted (1 of the 3 problems I will mention)
Here's what's happening: (3 problems total)
1: When you're finally lucky enough to get the car to start up (1 outta 10 attempts with cranking the engine) it misfires/runs on 2 cylinders. Takes A LOT of throttle feathering to get the engine to start up.
2: (might have figured this out, but since the car starts 1/10 times, I haven't gotten it to run to see) Basically, the tach in the car reads about 1/2 of what the tach in tuner studio reads (600-800rpm in car = 1500-1900rpm in tunerstudio). I think I found the setting that caused this, but as I mentioned, the car won't start up every time. So I have yet to get lucky and make it run to test this.
3: I cannot calibrate the ignition timing the way that the instruction manual instructs to do. Trigger offset (when fixed advance is set to fixed timing, then base timing set to 10* as instructions say to do) has no effect on timing. When I check the ignition timing with my light, it reads 13* (stock 4-tooth wheel), then when I try to correct what the computer reads (again, following the instructions), the timing on the crank pulley changes to 14*, and only keeps moving when I try to make the readings match.
So far, I've confirmed that the coils fire (OEM 99-00 coils for now, Fab9 COP after the megasquirt is fully functional), all decently bright (it's dark out now, just checked them). When I pulled the plugs, cylinder 1 & 3 were black as black can be, whole cylinder 2&4 were white as sour cream! My guess is that 2&4 aren't getting any fuel whatsoever, which is why it won't hardly start, and when it does it runs on 2 cylinders (duh right?).
Anywho. If anyone can offer up some help before I email DIY Autotune, that'd be great. I was planning on installing my turbo kit this weekend, so the ms2 is a definite must.
