Thanks for the feedback. I'm still a little leary of the timing tuning - too bad there isn't a way to monitor where you are in timing without by necessity inducing detonation. With regards to the timing, does the PCM still have the ability to yank back timing if it detects a signal from the knock sensor (e.g. hotter day than when you set up the timing tables)? It sounds like the Emanage unit is taking an ignitition signal in from the PCM so I would expect the answer to be yes, but if that's how the unit is working then how is it able to handle negative shifts in the timing unless it is internally delaying the ignition signal that is intended for the present cycle until the subsequent cycle.
By the way, the comment I made about the ability to decrease fuel came from an early post where you indicated that the injector signal could only be increased, not decreased. What I now realize is that you have control over the fuel with both the MAF 'correction' and the injector duty cycle 'correction', but only the MAF one allows for both negative and positive changes. To ask another naive question, why are both tables needed when it looks like both are adjusting the same final parameter (fuel injected) as a function of the same input (manifold pressure via the MAF reading) - I'm probably missing something else here.
Actually, am I correct with that statement that the y-axis parameter is always manifold pressure? Are any of the maps a function of throttle position?
Anyhow, looks like a good alternative to chips for those doing or planning major mod work (like 3L ). Is there anything that a Diablo or Superchip does that the GReddy can't do? Only thing that leaps to mind is possibly removal of RPM limiter and speed limiter. Do the chips get any more sophisticated in terms of monitoring more variables (e.g. temperature) to make their decisions?
