First of all, WHAT KIND OF CAR IS IT?

If its a 88-91 EF then you NEED TO CONVERT TO OBD1. Buy a harness from www.boomslang.us

Then buy an ECU from me for $150 , for that engine id give you a P75 Non Vtec. Then you would get the car tuned.

If you already have an ECU that is OBD1, PM me an i will tell you what it costs to chip it.

If the car is OBD1, then all you need it to get an ECU from me to have the car tuned.

Its really easy.
