SRT-4 High Octane Mode discussion.

[glhs837]

This thread will be a discussion of using water injection to stand in for the "+100" octane required by Mopar Performances Stage 2 and 3R Turbo upgrade kits with Turob Toys for the SRT-4.

The kits have a switch panel that includes a HOM button. This button, as described, advance spark timing and adjust fuel to take advantage of higher octane fuel. With Stage 2, this feature is good for a +20whp power increase.

While this kind of "tuning for race gas" is common in the aftermarket, the main benefit here is that this mode comes with the full suite of protections afforded by using the stock computer system.

Meaning timing pulls and added fuel for cooling if intake temps rise, and also if kcock is detected. One of the main boogeymen of the anti-injection crowd is that if the system fails, your car can suffer. With the stock system on watch, this isn't an issue. Ow, more later, my fingers hurt
