No Secondry Power - ZR-1 Net Registry Forums

what a cool project. I would contact Marc Haibec. if the ECM has any fault codes, often the secondaries are disabled. on a car that light, you really don't need them. you can revise the programming in the memcal, and just eliiminate them altogether and not hassle with them. on a car that light the loss of low end torq might even help you hook a bit better with a nice pay back in more top end.

the car will drive nicely when calibrated to run without them. I'm considering ditching them myself as there is a fair gain without them in flow and parts left out don't weigh or break.

the factory manual should help you trouble shoot why they aren't working and know what is required.
