P07-A00 ECU vs P28-A01
 

Just wondering what the differences would be with running a P07-A00 ECU in my 93 civic ex instead of the correct ECU (P28-A01).

I have another thread in this same forum about how my ECU got stolen and have a question there about getting a replacement. For the time being, I'm using a P07-A00 just to have the car running. Is this bad? I'm getting much worse gas milage - I'm pretty sure it's due to the fact that the P07 is a richer-running ECU. The car also has a noticable loss in power; again, I'm pretty sure because the fuel maps are off.

Please let me know what you think on this. Thanks!

Well, by the advice of a mechanic friend, I bought the questionable P28, at least as a temporary solution. It's running great now.

u need the right ecu p28 is the better.. make the motor run alot better if it came with the motor then go get a p28.. get ur power back

The p07 is a nonvtec computer. The p28 is the one you need.

It u still have the p07 I have A p28 I will trade the p07 is for the vtec economy motor
