New 2 step code developed for all LS1 PCM's

Operation goes like this at a drag strip.
Car is staged with trans-brake on which engages first and reverse gears at the same time. This stops the car from moving while the stall convertor is loaded up to rpm rev limiter of pill #1. On the release of the trans-brake the reverse gear is disengaged and at the same time pill #2 is now the new rev limiter which would normally be set at your usual highest RPM point.
Last week we finalized new code for a 2 step operation within the LS1 PCM.
No 2 step module and coil packs required as the standard PCM does it all by its self.

If you don't know what it does, why do you want or think you need one???? Not trying to flame, just curious.
BTW, Harlan is the only one that makes a LS1 compatible 2-step. www.harlan-engineering.com

Delphi.....how do you plan to trigger it and turn it off???? I assume the PCM sees the factory clutch switch to turn it off, but I like to know how you're going to activate it.

That's a good question. Also how are you incorporating this into the PCM? Can it be done with HP tuners? I don't suppose you work for Delphi do you?
So is Delphi getting in the performance aftermarket ring now?

2 step Ok here is a question with harlens 2 step isnt it cutting out spark so you are sending raw fuel thru the exhaust in to the cats. Which in no time will damage the cats. For guys like myself without cats this would be ok. Still doesnt seem to be the best way to go. For a car with cats sounds like problems to me. Scott

Spark drop is the way most if not all of the currently available options do it.
IMO, if you start messing with fuel and don't shut the injector off completely or at the right time you lean that cylinder out real quick. I'd rather have a weak spark from short dwell than a lean hole.
Not to mention even injector shutoff can damage CAT's, unburt air does neat things to brick temps in the catalyst.
In any case, a 2 step is a race application piece.
carry on

Yes...it's an old thread, I know. I really want one of these since I've got a stall on the way now. I don't have cats, as you can see in my sig. Can I use this on the stock 4l60e? Can I just use the foot brake instead of a transbrake?
I'm guessing, stall, tranny cooler, 2 step, and DR's....will that be a safe set up for a daily driver? Does the 2 step have to be engaged and then shut off?
Thanks.
