Enrich Desoot mode - what years is it available for?

[thesubfloor]

I'm still using version 2.24 but have considered upgrading to version 3.6 for the Enrich Desoot mode functionality in hopes of eliminating some huge lean spikes when I launch the car at the track.

I'm a little confused though as to whether it's available for my 2007 Corvette. I browsed several tunes in the repository (using version 3.6 on my work laptop) but didn't see it show up in anything for 2007 but did see it in some (but not all) of the 2008 ones I looked at so I'm not sure what's going on.

Is it not available for 2007 or would I only see it in my tune after doing a read entire using 3.6?

Thanks in advance,
Christopher

I know it's not available for all of them, because I have requested it on a few and was told it wasn't available - not sure if yours is one of those...

If it's not available then you most likely have something else going on...

Looks like GM started using that programming (Enable vs Disable switch) beginning in the 2008 model year calibrations. Have never seen it in any of the early Gen 4 controllers.

mine is 2007 and its not there but also not needed because no issue caused by it, i also have a 2008 ecu that it does have in it, looks to be early to late 08 might be the changing point

HP Tuners added it to all Gen IV ECM's that utilize it. If it's not in yours, GM didn't use it.

Not in my 07 vette either. Havent had a need for it luckily.

Every desoot problem I've seen, including mine, has shown up 2.1 secs after entering PE. It might be something else if you're going lean at launch.
A log showing WB and EQ command would help confirm it.
