On the third day of Christmas my true love brought to me...
This is the Terminator X Max system that will replace the GMPP ECU and harness kit. Given that my business now is tuning Holley EFI systems, it makes sense that I run what I preach.
The Terminator X Max will allow me to retain the DBW and also allow me to implement things like pwm fan control, and any other feature that I want to implement.
I also plan to take my time with the wiring. The Holley harness is ok, but some of the more visible parts are not up to a super clean look. The plan is to make my own injector and coil harness. Making those sub harnesses more like a motorsport harness and fully heat shrinking and labeling them. Some of the sensor branches of the harness may also get the same heat shrink covering. I also plan to integrate the alternator L and S terminals into the main harness.
More to come!

Why the Terminator X over the HP system (https://www.holley.com/products/fuel...parts/550-604N)"You can never go home again, Oatman...
But I guess you can shop there."
