if ima do an ls vtec on a 94 eg, can i do a p72 obd2 ecu, if its gonna be chipped, does it matter whether its obd1 or obd2. please, i kinda think that i can't, i jus wanna be reinforced on my opinion. thanx. and same for the wiring harness, harness came out of an obd2 integra(?).....thanx again

 

You can't chip an obd2 ecu with hondata, crome, ectune, neptune etc. It would be a waste of time & money to run an obd2 ecu.

Get your self a chipped obd1 vtec ecu.
