Does anyone have a Supercharged LS1 or LS6 or natually aspirated car they use a spark control box on?

I have a supercharged 2001 Tahoe with an energized 6 liter. I need to adjust timing for the winter. I don't want to use LS1 edit every time the weather changes.

My 96 ZR28 has a Vortec LT4 set up in it with a "Timming/boost " control knob in it. I want something like that so I can make changes easily. My turbo car has a Greddy set up in it to adjust boost.

Can this be simple..

MSD and Crane make boxes that can intercept the crank trigger signal and delay/advance it a few degrees. So the pcm would still shoot for the same advance number, but would be basing it on a delayed trigger signal.

Is your IAT sensor before or after the blower?

Seems like if it was after the blower, then the pcm would manage the timing correctly on its own.

The only thing I know of is a product called "Timing Tuner". The Crane and MSD units are not designed for LS1/6 style ignition. I know TByrnemotorsports.com sells it (289.95). I haven't used it myself but have a recommendation from others that it does what it says it will.

I have talked to TByrne, he said "No Dice" I am still hopefull something will come out.

Timming Tuner is what they say will work. Bobbylee, thanks for the tip. I'll keep you posted on how well it works or doesn't.

I have at least figured out the I have enough fuel. 58lbs injectors.

I would say 58# injectors are big enough. I've not had any experience with blowers or turbos but it is an area that I have been studying with great interest. Those injectors should be able to support over 700 hp using .5 as a bsfc figure. Did you buy the Tahoe already set up like this or is it your own custom install? Keep us posted on the results. I know of one drag race type using Timing Tuner with nitrous. At least he hasn't blown anything yet.
