Have a question about the ecu for my car. I have a zc swap in my crx now. With the pm6 ecu the car starts up and idles great with no problems whatsoever. With the pm7 ecu that I put in the car starts but it has to crank for a couple seconds, it stumbles a little bit and then the idle jumps up real high and takes awhile to kick down. If the car has been sitting for a week or more it has a real hard time trying to start too. But the pm6 does not do this. There are no cel lights. Anybody have any idea why it would do this?
