I just swapped an JDM F22B DOHC into my 92 prelude. I am using the stock h23 ECU but I kinda want to get the F22 Ecu. Is it worth it? can I just chip my H23 ecu? what should I do.

 

Take it to a dyno to see what things look like.......maybe a used safc?

 

safc?

 

Using the F22B ECU will do two things. It'll lean it out (vs the H23 ECU) and it will delete the knock sensor you don't have. Or, you could get a chipped P75 ECU and just get it tuned to your specific setup

APEXi Super Air Flow Convertor
so you can at least tune your air/fuel a bit..

 

isnt the p75 for an integra?

Logical guess would be a DOHC NON-VTEC B series....not sure though.

 

does using the jdm ecu make that big a differance cuz i have a jdm f22 swap and i burn gas like crazy

 

f22b DOHC?

P39 is the correct ECU for that motor.
