We already had a bunch of this type of stuff for the LSJ a couple years ago. From our LSJ turbo kit page:
Adjustable launch control rev limiter 2500-5500
Raised ceiling for MAF sensor table for much higher HP potential
ECM tuning capability for boost levels up to 28psi
Full MAP scaling adjusts fuel up to 25psi boost pressures
Revised cooling fan control capabilities
High octane mode
Nitrous input

I've seen people use their neutral rev limiter as a "launch control" in HPtuners, but having a more professional way of doing it would be preferred imo
I'm definitely interested in this. sounds great! looking forward to how this develops. having the opportunity to rev out to 8-9k would be sick! I also like the idea of adjustable launch control. keep up the good work guys

I've got one...
An Ethanol mixture virtual sensor or input for a physical sensor.
Automatically adjusts for the Ethanol content. It'd allow people to fill up on whatever they want, whenever they want, and also do away with the wandering trims with every tank for those that do mixes or as seasonal-mixes change.

I said this:
Why can't a Cobalt (particularly an LNF) be "retrofitted" to run E85 with a tune that adjusts timing due to whatever percentage of ethanol is currently going through the fuel lines?
Maybe using something like this:
TTP Engineering
or some other E85 content analyzer.
This would be great. If you want power you just add more E85. If you're in a place that doesn't have E, you can use pump gas. If you've got a mix, no problem.
This is what he said:
It’s a good idea, and that’s basically how the LHU does alcohol calculations, but the question is what input on the ECM are you going to wire it up to?
Then I said this:
That's waaaaayy over my head. I just come up with the ideas. You gotta do the hard part. LOL.
Then he said this:
I guess my point is there’s no input to use for that, so we can’t do it.
Then I said this:
bummer. I still say it was a good idea though. lol
If someone can find a way to do it with HPT..... instant millionaire.

I proposed this in September in the tuning section. Only two people responded so I sent it to Vince.

1) This was a custom ECM idea, and nobody said there couldn't be hardware differences, so I took it as a blank slate kind of question. If it really is software only, then on to number 2...
2) If you do it virtually with the O2 sensor, like some cars are programmed to do now without the dedicated tank sensor(s), then you won't even need the input.
Yes please!
