Thank you for your help. I assume that the ignition timing will take care of itself.
The engine management that I use is the UTEC. I or a tuner can reduce the amont of fuel injected. There is no feedback between the 1s and the UTEC. If the Water system craps out, I'm a lean running detonating Yank.

I gained 13% in hp and torque and dropped my AFR from 10.8 to 12 while keeping the EGT the same.

When you are working with Phil in integrating with the Hydra, is there a feedback between the two?
