I own a 1999 Civic Si with a b16a motor I'm currently using a chipped Po7 Ecu but I want to go back to stock and go with the p2t Ecu because I'm currently having issues with the po7. How do I replace the po7 with the p2t do I just remove the old one a connect the p2t Ecu or do I have to do something before i add the stock Ecu, for example do I need to do some special adjustment or something?
I'm currently using a chipped Po7 ecu on my civic with a b16a motor it's been running good for the past 4months but it's starts to idle up and down and shut off only when I'm at a stop. Not sure if it's the ECU but can I use a different ECU on my car and have no problems or do I need the stock p28 for more long lasting reliablility I feel like it's the ECU or sensor not sure becuase every thing from the motor sounds good and no overheats or strange noises,please help!!??? Also it only happens sometimes and not all times I have some days that I don't have no issues mostly when I drive for over 40 mins. It starts to idle issue

can someone help me please, well I had this problem for the past 3 years now base on my car. I own a 99' manual Honda Civic Si, once I drive it for a good 45-60 min. after the engine get hot, everything start to stop working. I mean the engine still running but once I step on the gas peddle, it will not move or go forward. All you can hear is the engine running loud, but will not move. Just can't afford to get it fix at the auto shop. I had ask a lot of people for help, but no one seem to know the right answer. So please can someone out there give me the actual answer. What cost the problem?
