is it possible to run a h22a with a p72. what i mean is the ecu is plug and i drive the car right after or i need to modifie something..

 

you can use that ecu and it will run everything fine since its the only other ecu that actually has a IAB control although it will run like crap. that 2.2 inst getting the fuel it is supposed to out of that 1.8 and the timing is completely different so up until top end it will feel like total ****. if you can use a jdm p72 the timing on it is more advanced and if you advance your timing a bit more it will feel a lot better almost like a P13 ecu.
