how do I... (URGENT DYNO TOMORROW MORNING)
 

How do I check a code on a car that has been converted from OBD2 to OBD1? I just put a P28 in my car and I have a chck light and it runs funny. I'm running uberdata w/ a stock P28 bin on a stock non-turbo Y8 and it seems to be running semi-ok bu maybe a bit rich or something. the check light is on, so I need to figure that out, I am supposed to dyno on a new setup toorrow morning but I need to figure this out first.

cant you just put a jumper in the service connector like normal?

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

yes, you check it just like normal. if it's a solid cel, it's a fucked up burn, just try to reburn the chip. and yes, a completely stock ud rom will run a little rich.

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

short c4 to ground. anyone confirm?

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

cut j1 to return to to stock rom, if the cel goes away, you know it was the burn if the cel goes away. did you create the basemap or get it from someone else? it has to be saved in the ud directory, not just saved to like 'my documents' or something,

Cant he just jump the service connector and get the codes like OBDI?

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

yes, but bad burns usually throw solid cel's that contain no codes, so it wouldn't do any good ;)

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

And the car will run in safe mode with solid cel.

Bamboo...did you get this sorted out?

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

A topis along the same lines....how would you check codes on a OBD1 ECU in a OBD0 car?

There is a service connector but OBD0 ECUs always blinked themselves...

Do you have to ground anything or wire up your own check engine light?

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

not neccessarily ;)

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

he`s been busy working on his new poject.
he jumped the code, it shows a 4, crank posistion sensor.
we through it might be the ECU, but then it throws the same code with a different ecu with a different chip.
i belive he`s trying to obtain another obd2 to 1 adapter

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

i had the same problem, same sensor even, check all your connections on the harness, one of mine had come loose and i couldn't tell b/c the shrinkwrap was still around the connection. give them all a stout tug to see if maybe one came loose but is still holding together :-\

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

the problem is it doesn`t throw no code after he switch back to stock ecu :-\

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

So check the adapter harness not the stock harness the connections my be broken.

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

98% sure it's a bad burn
1% bad ecu
1% conversion harness


just reburn tha damn chip for ---- sakes, don't you have access to donalds burner??

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

but he said he tested it on a diff ecu with a diff chip... same code... calm down kev lol

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

settle bro...at least its not your car :-\

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

yeah i just almost converted to obd1 and you can just use the obd2 jumper to get the obd1 codes. thats how i got my code 14

Re:how do I... (URGENT DYNO TOMORROW MORNING)
 

it happened on his ecu with his chip.
it happend again when he burn it the second time, i even talked him throught the map and the burn

i let him borrowed a chipped ecu which worked fine with my chip in my car, but it still throwed a code on his.

weired.
that`s y we are thinking it is the adapter.
relex Kev. :P

sorry, w/ all the commotion in the past couple of days I forgot I even made this post. It ended up being the harness. boomslang actually next day aired me another one and everything worked out, that is why if you look at my ITB post the first tune was VAFC and the second tune was über tuesday was AFC, thursday was über)
