obd2 to obd1 conversion??

so yesterday i did the obd2 to obd1 conversion, and i am having a lot of problems.

1. car feels very, very sluggish and little throttle response.
2. Car stalls at lights, and refuses to start after being turned off for a while.
3. RPMS bounce between 100rpms and 700rpms.

i had to put my obd2 ecu back in, it started right up and felt perfect again. Can anyone tell me what the problem may be.

thanks a lot

what ecu on what chassis on what setup to be running an obd1 conversion?

1999 integra ls 4door to an 94 p75 ecu i'm running a jackson racing supercharger, dc header, 2.5 exhaust, and other little stuff.

the ECU needs to be tuned to your set up....

the ECU needs to be tuned to your set up....

My stock ecu isn't tuned to my set up. Why should this ECU be different? all im running is an fmu.

bad ecu?

anyways, getting to the most important part. if you are running the JR fmu, its pointless to bother with the obd1 ecu.
