im goin gto be running Ls/Vtec wondering which Ecu would be better to rechip a P28 or a USDM P30 ecu from a 5 speed del sol vtec

 

Since you won't have a knock sensor, may as well get the P28, as you'd just have to disable the sensor in the P30 anyway. Once you chip them, they're both the same, you can put whatever maps and all that in them you want.

 

Get the p28 chipped
