MS2 Install with AbeFM PNP Adapter Board
 
I finally gotten around installing my MS with AbeFM's PNP Adapter Board. I waited so long because I got frustrated on my first attempt. I almost sold the MS with the adapter board but good thing I held on to it and had Abe look at it again. :noob:

Anyway, I wired it up without my laptop hooked up to it. I wasn't really anticipating that the MS would work that's why I didn't even bother with the laptop. Fired it up, and it started! Whohoooo! WOW. I waited so long and it just fired right up. But the car would not stay idle, I think it's running rich. And the battery indicator light is on but faint. Obviously it needs more tuning. It was 11:30 at night and I don't feel like messing with it. I am going to hook up the laptop tomorrow morning and see if I can tune this.

Any ideas or tips would be appreciated. :noob:

If it wouldn't stay idling, did you change the Idle transistor? There was an issue with the first transistor that Abe used that had a bad spec and didn't run the idle valve properly. You can use a TIP120, TIP122, or the other type that Abe provided if you haven't changed that yet.

The battery indicator light being faint is normal for Abe's board. He suggested adding a capacitor to somewhere on one of the small transistors to solve the problem, but I haven't got around to doing it at all.

Post your MSQ or pictures of your idle settings, and we will try to get it up and running good.

I changed the idle transistor. Car runs now, I adjusted the idle screw. It's a bit rough. Car runs rich too. I'll post the MSQ later.

Congrats!!! My battery light was on dimly too. There is a capacitor that you can solder in to get rid of that issue. I'm on here through my iPhone at work, so when I get home I'll find a picture that you need. As for the idle, I never touched my idle screw ever. It is still the factory preset adjustment. I assume you calibrated your tps correctly?

lsc224 03-07-2010 07:36 PM

:facepalm: Since I know the MS works, I put the stock ECU back and now the car won't start. Damn, it won't even crank, it just dies like the battery died.

Plugged the MS back and my car does not start.

Wow, you seem to be having the exact same issues I was having. Is the engine cranking?Is your fuel pump running? Take a meter and test resistance on the coils between 1&4 and 2&3. Tell me what you get. When mine didn't start, coil 1 was blown.

Engine does not crank, I don't hear the fuel pump. Yeah I think I fried the coils. Bummer

Check your main relay on the passengers side at the wheel well. It should still crank though, is your battery dead?

I strongly doubt you fried your coils, it sounds like you blew a fuse. Check the fuses like thirdgen suggested.

lsc224 03-07-2010 11:02 PM

Thanks for all your help. I'll troubleshoot it tomorrow, hopefully it's just a fuse. I'll keep you posted.

Well the verdict is, I fried both my coilpacks. :facepalm: Geez! All fuses are good. I don't get any resistance on my coilpacks.

Marc D 03-08-2010 07:32 PM

ouch. Wonder how that happened. Good excuse to upgrade to cops?

thirdgen 03-08-2010 09:11 PM

Are you sure they're toasted? I couldn't get my test leads inside the towers, so I used some scrap wire and stuck that down inside. Coil 1 was shot, coil 2 was ok.

thirdgen 03-08-2010 09:12 PM

Also, if I remember right, Abe's .msq was set for inverted spark (for cop use) make sure it is set to non inverted.

Yes they are, I used a screwdriver to reach inside the towers.

This was my MSQ file. Can anybody tell me how I fried my coilpack?

Assuming my fresh install of TS is good, it looks like it was set right. No cranking doesn't seem like a coil pack issue - it'll happily crank all day, I think even with the computer unplugged altogether. Of course, different people have different terminology.

When you say "cranking" you mean the motor never rotates? Thirdgen, as your car had a similar issue, do you remember if the rest of it worked?

When I fried my coil, the connector got all melty, it was pretty obvious.

Of course, it only changed shape because I touched it when it was hot.

Yes the motor did not crank at all.

Marc D 03-09-2010 01:34 PM

^^^ holey moley.


Anyway, if your motor didn't crank at all, there's something else at work here.
