I just had my new motor put into my 94 integra. I had a usdm gsr motor and it blew and I bought a jdm gsr motor and install it about a month ago. I finally did a test run and the redline is not hitting the 8100 or the gsr redline mark. Instead it is hitting around the 6500-7000 mark. what can I do to fix the redline? help please

 

what ecu are you using? any CEL's?

 

it sounds like ur usin a p75 ecu

 

i am using the ecu that was originally on the motor before, which was the usdm gsr motor.

That's not going to work. You need to match it up with a JDM ECU.

 

i have a jdm gsr, I am using a chipped p28. Works like a charm, also its ready at any time to be tuned on a standalone. Check out J-K tuning. He's a good guy.

 

jdm engines also dont have a vtec pressure switch, which a usdm ecu will look for
