I just pulled out my ECU with ahmed chips, just wasnt happy with it. Fitted it with an EMS ECU and an MSD DIS4 running 4 msd blaster coils. No wasted spark! and capacitive discharge.

Was a simple and pretty install, used the stock wiring, didnt have to pull out the harness and replace. Also stock sending units. Its like a new car, and no more cap and rotor!!!!!!!

So if youre a do-it-yourselfer, I highly recommend the change, and its easy to do.
