E21 project thread

Well our initial thought doesn't seem to be the case, but still doing some testing on injector wiring.
-
Update: Was testing the wiring for the injector pins just now. Checked continuity between the injector clip pins and chassis ground, got nothing which is good. Then I tested continuity between the injector pins on the MS db37 connector and the injector clips. Db37 pins 34 & 35 tested good against cyl 2 & 4 injector clips. Db37 pin 33 tested good against cyl 1 & 3 injector clips, but db37 pin 32 was a no go. Hhmmm interesting. Took apart the db37 plug and unwrapped the tape around wires and found this for pin 32.
That wire for pin 32 popped out of the db37 connector pin, which is why continuity was zero. Getting closer! So now I just need to figure out how to get that wire back in and seated right and see if that fixes my issues.

Well good news!! I ended up buying a d-sub crimper tool and a d-sub extractor/insertion tool from radio shack. I was a bitch extracting the pin from the connector without the wire attached, but eventually got it with the help of a bent paperclip. when attempting to recrimp the wire onto the old pin, the pin broke in half. Went back to radio shack and bought some new pins. Crimped wire and inserted back into connector with tool. BINGO!!! Continuity on pin 32 is now golden. Put wiring back together, installed injector clips, throttle body and charge piping again and fired her up.
She runs amazingly smooth now with no more shutter! I am assuming that with the one wire connected to injectors 1&3 that they werent getting enough current to fire enough fuel, causing the shutter. Now I just need to retune everything since its running super rich and i should be good to go!!

flares probably won't be done till winter or even next year. The car needs mucho body work done before the flares can even go on too.
-
yeah, yeah, yeah
-
=( Well at least post a bunrout video!
Second this, can I get a third?
-
Third on burnout videos
-
I call the fif
I corrected that for you
-
Oh yea... Sixth!
-
Awww yeah! Bluetooth megasquirt baby!
-
So of course right before the October meet, the curse of fat bob haunts the ol' E21 once again! It seems that the injector drivers in the megasquirt might have been fried due to a short in the electrical. I am doing some diagnosing and have ordered some new FETs from DIYAutotune, but I highly doubt I will get them and installed in time. That is if they are the only issue here.

Damn damn damn!
^That
should have paid the $30 overnight shipping for $2 worth of parts.
you gotta be like a squirrel and accumulate scene points before winter.
store them in your cheeks even.

Well since the car didn't make it for the last meet of the season, figured it was time to start on the interior. I took the seats out (which are for sale of anyone is interested) and ripped the nasty carpet out partly so far. Irritates the crap out of me that my car was relatively rust free when I got it, was forced to drive it that first winter and this is what happens ...
Guess this means my winter project is cutting out the floors and welding in new pans. And of course figuring out the electrical issue in the first place.
