Ok I have read on here about how you cant run the PR4 Non OBD with hondata. You have to use the P74or P75. Cant I run a OBD1 PR4 instead?
Whats the difference on the ecu's? anything? Cuz I know they changed the ECU codes but a 92 Integra PR4 is obd1 and you guys list it on the list. But on these forums you guys never talk about them just the p74 & p75.
By the way this is for a civic with a complete integra harness (interior/exterior (non obd)). 91 civic
