I have a 96 GSR.. today I had a friend install two-step, full throttle shift and had the iab's engage early. Burned the chip, put it in an OBD1 ecu, used a harness and hooked it up.. car runs great, all features work. However, I head a whining noise coming from around the battery in the engine bay. I removed the jumper from the ecu to revert to the stock programming, but noise was still there. Put back in OBD2 ecu, noise went away. Anyone have any experience with this? noise was very high pitched whistle. could not pinpoint the location of it.

 

wow... NO one?

 

a whining noise near the battery and it stopped when you switched ECUs? Sounds like it is electrical possibly. Try a different OBDI ECU that isn't chipped.

 

thanks for the response. this is gonna suck, cause that ecu isn't cheap. i'll have to find someone with a nonchipped ecu and see how it works..thanks.

Yeah.. electrical problems can cause something like that.
Do you hear it more from the inside or outside of the car? I'm assuming inside, since

 

the noise was in the engine bay
