"I chipped my ecm last month, and after screwing with it for about a month I finally got uberdata working, along with my wideband and datalogging. After all that, I got out of class on tuesday to start my car and found that it will not start. The first thing I noticed was that my MFR was clicking back and forth like crazy and the fuel pump wasn’t turning on. So I did what most people would and assumed that my MFR was fried. First I tried shorting pins 1,3,and 7 on the MFR to force the fuel pump and ecm on so I could drive home, but that didn’t work. So I pulled apart the whole thing and tested it as per service manual instructions, and found that the MFR and the supporting circuitry works fine (ruled everything out using their troubleshooting flowcharts.) SO, I called my friend to drive 90 minutes and bring his OBD-1 ecu to my car so we could rule out the ecm as a problem, and his ecm starts my car.
Jumping the service connector yeilds a solid CEL (code 0?)
Will the P28 work just the same? Chipping job verified to work properly I mean… I was using this ecu for quite a bit with uberdata, doing datalogging and wideband tuning.
Will it work the same as the P61 though? (i.e. knock sensor, works for uberdata datalogging, etc.) I just want to make sure. And you said it’s chipped or unchipped?
Xenocron you seem fairly experianced with this stuff, do you think the P28 will work well with my car? I think I posted the engine stats somewhere… Will I miss the knock sensor much when I am tuning my boost maps this summer?
Well, you wont miss much with the knock sensor as it only can detect knock up to about 4000rpms.
Any P28 can be converted easily to run the IABs on your GSR or you can just disable them which is what a lot of boosted Hondas do as with FI it wont make much difference (Shorter vs. Longer runners in the IM)
