Civic EG

ok i was jw iam doing a gsr swap but i dont have the p28 yet so iam going to use py ls ecu now will it wrong the car it just wont look for vtec right its just going to be like driving my ls right ? any1 know

should be true i dont see why it wouldnt just try it and see i dont think it will hurt anything

The engine will start and run. however wont run correctly. as your not using the correct fuel and tming maps.

BTW OEM GSR is P72. P28's can be chipped to run p72 Software however a stock p28 will Run a GSR quite crappy.

but this p28 has ran two gsr in two diff tegs with no probs

I would stick with the stock p72

well i would toobuti donthave it and have a b16 head and all i have is a p28 and a ls computer my qestion is would the ls work untill i get a chipped p28 i mean its for a 1.8 liter just wont hit vtec right ?

The P75 ecu will start and run the gsr motor. It will not feel or act anything like an LS though. The fuel and timing maps will be off, you might also get detonation from the sheer fact that the GSR has a higher CR than a LS.
