Holley Pro Jection 4di MPFI ECU & Harness
This is the older Holley ECU from the 90s. This unit is from 1999. It controls fuel and spark using a GUI interface and a serial cable. I have the ECU as well as the wiring harness for Multiport Fuel Injection. (TPI, not TBI).
The ECU can do EITHER TBI or TPI, with the appropriate harness.
I have not used this, I got it as a package deal with other parts.
So, I will sell the ECU & Harness for $250 plus shipping OR I will sell just the ECU for $200. (for guys that need a replacement ECU).
The EEC software is available on Holley's website for those who want to see how it works.
If you are looking for a cheap way to retrofit EFI into a older car, this is probably it.
