Ok just plugged in the new obd1 ecu in my 96 integra. Started up fine and i let it set for about 3-4 minutes then i tried to take off and when i gave it gas it just died. then i tried to start it and it took me about a minute for it to start and then it finally started. Then i was like ok whatever so i gave it some gas and it almost died again. Now its sitting in the driveway idling. Do i need to reset the battery or the ecu fuse? HELP!

 

well your using an OBD1 ecu in an OBD2 car

 

i have the obd2a-obd1 harness......

 

Is it throwing any CELs?

I would double check that harness since that is usually the problem with OBD2 to OBD1 conversions.

 

Is the ECU running an aftermarket chip in it? The problem is either the harness or the ECU. Try finding a friend that has either a known good harness or ECU, and put in one of them and see if that fixes the problem.

 

Problem fixed....hopefully...Yea it's a chipped obd1 ecu and after i posted this i pulled the ecu fuse and let it sit for about 15 minutes, then i put the fuse back in and she started right up. weird? my obd2 ecu was throwing a 65 code but now its gone and the ecu runs very well. But yesterday after running it for a while i shut the car off and when i tried to start it up it took about 30 seconds and i thought i was screwed again but she ran good all last night no problem and now i have some more "umph"
Thanks

 

Was your fuel level low that last time you tried to start it? Hondas/Acuras are notorious for taking a bit longer to start on a low fuel tank...

 

ok...maybe i spoke too soon. Went for a drive just a little bit ago and the car likes to die at lights and dosent want to start anybody else ever go through this with a chipped ecu?

 

What program is it chipped with?

 

A lesson to anyone reading this and thinks that throwing an untunable chip on an ECU is a good idea... think again. h:
