It may be awhile for the Beta Version to come to life, but so far all of the parameters that are available on LS2Edit, are also available on LS7Edit.

There is no "Off Board" Programming available yet since the new 32 bit ECM connectors are not available anywhere. I even checked with Vetronix, who are the folks that bring you the Tech 2 and MIS2000 Programming, and they have none.

Within a week or so, I suspect that many tuners will be up and running with the LS7Edit program.

It looks like GM finally caught on the game. For years the Mustangs had a concepts of offering from the factory a modest hp'ed car but with countless options and potentials for mods. I think that is the one of reasons it out sold the LT1/LS1 F-bodies. That game was really continued on with the ricer crowd. $1,000 buys you a lot of cheap powers for you kittle civic, evo's.

Now we have a LS7 that is potentially a 650 hp engine offered at 505. With a little tweak here and there, you got yourself a moster car without having to void your warranty. This Z06 is looking to be the best bargin in the history of sportscars.

Foosh

Yes, the potential within sounds simply unbelievable. Thanks Jim.

someone tune this thing asap...i wont be able to sleep until I know.

TetraU, you're correct about the Stang and Import HP comments. But actually, GM has played the "modest HP" games like the other manufactures before...remember the GN/GNX?
And yes, the Z06 is a monsters waiting to come out...that baby is very de-tuned; I can't wait to jack around with the PCM parameters

Download successful!

We just finished our prototype LS7 RACE filter, so both the LS7Edit Program and our filter got the test today.

One word. What a HUGE difference in performance!!!!

I did a quick a/f ratio tune, timing tables, torque management delete, rev limiter, and a few other tricks.

I think this is the first Z06 to have LS7Edit downloaded through the OBDII.

Lou G. has his up and running now as well. We've been collaborating.

gains?

Too hard to tell by SOTP and zero traction in 1st, even at a 35 mph roll and new Viper rubber in the rear and front.

Dyno testing this week if it doesn't snow.

bernrex

Best news of the week, month, year !!! Big thanxs to J.H. and Lou.

You guys keep us STOKED !

I'd guess from what you say ... dyno will be @ 525 RWHP/ 515 RWTQ levels.

Here is some screens of a few torque management tables:

What torque numbers would be produced at the different RPM levels if the computer didn't limit it? Will you change the torque values, or just turn it off completely?

Halltech

It is done differently by each tuner. The result is about the same. Most of the parameters for torque management are there to protect the tranny and rear end assy.

We have already witnessed a rear axle break here on the forum, even with TM onboard, so this area comes with no warranty. Change it at your own risk.

Having said that, it makes no sense to add timing, just to have the launch control pull it back when you drop the hammer.

Dynotech cradles would be in order and M300 half shafts. I would like to see them made in titanium.

JDogg

I can see why the folks in Detroit/Warren put the TM in there if this is what you see with some early tuning. They have to be able to warranty something.

A 427 ci with the flow that is there in the heads and long tubes from (insert vendor here) that is making 500 rwhp...tweak the tuning...550 shouldn't be crazy.

Halltech

I don't know what we added today, but it is a different ride tonight. Our first prototype intake and programming made a BIG difference. How much? Really hard to say in this HP range, but the torque is very noticeable.

I posted the a/f ratio graph (stock) vs. our straightline 12.8:1 ratio:

Webfoot

Don't know what you did to make such a big difference? Hope you figure that one out!! By the way, when you add these mods to boost HP and torque, the computer seems to be thwarting your efforts, at least at the low end. From the computer screens you posted, it appears TM is done after 3,000 RPM, so is that where you are feeling the difference? It seems to extract the most performance, you'll have to modify TM, even if that means strengthening the driveline. Stronger halfshafts may be in order, as you mentioned, and I've seen beefed-up rear ends become available. Is the trans going to be the Achilles heel?

If you want to take a screen shot of JUST the program that you are trying to copy, make that window active, and then press Alt+Prnt Scrn. Then save to whatever program that you want.

Not that I dont appreciate your whole screen, BUT it would just be more to the point to see JUST the program's window.

Deep Blue

Forgive me for being ignorant, but what is GM's goal with torque management?

Webfoot

To limit driveline stresses and to keep things from breaking, thereby limiting warranty claims.

bernrex

Also ... probably used it to optimize gas mileage at cruising speeds/RPM's.

And safety in the wrong hands...
