Ever since I have started using Holley's efi, I have always used a 2 step on the transbrake cars I've help and on my own personal race car.
I know the answer to this is going to be "every combo is different, you need to try for yourself". But someone with experience might be able to offer a little insight.
What if we just turned the limiter off and transbraked to max stall speed? In my case, with full timing in it, I would think my converter might grab the motor at 6500 rpm (fall back rpm after shift). When I use the retard function, the converter will only flash to 5500 at transbrake release (down on power with timing out of it).
I know some combos like have a "run at the converter", but what about a forced induction type set up that makes a lot of power. Leaving at max stall I'm sure could still net good 60 foots.
Anyway, I'm just thinking that could resolve the issue of fluctuating rpm launch, allowing at least for the time being, consistent data to get the chassis dialed in.
Anyone have anything to add?
