HP TUNERS

Hi,

Have Had my 07 Tahoe for a month now so its time for MODs...

my first mod is HP Tuner just got it last night still cant believe it but it works great ... i have already removed torque managment,firmed up the trany,removed the speed limiter,turned the fans on earlyer,and advanced the timing and WWWWWWWWOOOOOOOOOOOWWWWWWW what a different beast

you guys have got to check it out

where did you get it? How much? I want one!!

well i have been tuning my other truck for the past 2 years with it and i just got the new VCM 2.1 with 07 support . before you buy it i think you need to read all the help files go to this web site and read up on it first..

http://www.hptuners.com/

If a guy was interested in performance, but also fuel economy, can both be addressed with this programmer?

It looks pretty interesting, and I have read about them, but I'm interested in getting my 14mpg average up as much as I can.

Do you know if this is possible with this machine?

This software is AWSOME.. every GM owner should have a copy ... all you need is a laptop when you buy it they send you a cable and a CD and they include 8 credits.. you can tune 4 GM 98-06 (requiers 2 credits each) or two 07 Tahoes ( 4 credits each) when you run out of credits then just purchase more credits....

yeh you can tune for economy or performance just make different files ..you also have logging you can see what your car is doing...

here this is a good thread to read http://www.hptuners.com/forum/showthread.php?t=3833

Careful with this software because if not used properly you can do more damage to your vehicle than good. I haven't got it for my Tahoe as I don't plan to mod it (family vehicle). But, I tune my Ford Lightning with software called SCT Pro Racer (for Ford vehicles). This gives me just about the same amount of editing capabilities that HP Tuners does for GM vehicles.

Be careful as taking all or most torque management out WILL eventually toast your tranny. But, I'm sure you knew this (Black 5.3). These transmissions are not built to take many mods or power without the torque management for very long before crapping out. If you want more information on the software, check out LS1 Tech.

And yes, you can tune for somewhat better fuel economy with this software. Or, you can have a reputable tuner make you a fuel economy tune for this software (check LS1tech.com for info. on tuners). Most of the time the timing (timing is lowered) and shifts are changed to make for better fuel economy (along with other tweaks).

Happy programming

good advice bro.... but on a stock 07 Tahoe its prity safe to remove all Torque managment the 4l60 can handle over 350RWHP easy ... i removed all the torque managment and increased the base line pressure and moved my shift points up a bit truck feels incredible..

Are you saying that I could have a tuner/tech program my LTZ with their equipment? This would be great to get the re-program without having to purchase expensive equipment. I hear what you're saying about reputable, capable tuners. If this can be done, how would I go about finding a shop that does this?

I love the great info that you guys come up with on this site....Thanks!

You did almost exactly what the Tow/Haul feature does with the exception of disabling Torque Management which is just a bad idea plain and simple (nothing good can ever become of disabling this system).
The Torque Management system is designed to prevent damage caused by shock and/or abuse. The 4L60E tranny has the capability to withstand a tremendous amount of torque (horsepower means little to a transmission) so long as the torque is kept under control at critical stages of operation.

Just curious. Does Torque Mgmt retard timing during upshifts?

I'm not sure if most tuners do the 07's (you'll have to check). Check out the link in my previous post (click on the LS1Tech, it will link you to another website). Do a search there for tuners. You may find one in your area.

Or, you can try these websites http://westers_garage.eidnet.org/index2.htm and http://nelsonperformance.com/tuning.htm and http://www.mgscustomtune.com/

I hear good things about Westers and MGS Custom Tune (which I believe may use Wester's to tune there stuff, not sure). If anything, contact them all and tell them what you're looking for and see what they say.

Yes it does, sometimes quite a bit.
Think of GM's Torque Management System in the same way as driving a vehicle with a manual transmission, you would lift off the throttle before shifting, this is what TM is attempting to do for you, the reason is to extend the life of the powertrain and also to provide a better quality shift.
If you prefer a firmer performance shift then depress the Tow/Haul button at the end of the shift lever.

i have it a bit more agresive than the tow/haul button....and i kept the stock factory setting without tow/haul active..

yeh thats exactly what it dose it retards timing and on our trucks ETC it closes the butterfly slightly the more torque at the shift the more timing is pulled out

nelsons and westers tunes...no way you are looking at $500 for a mail order tune they charge more than the software it self..your best bet is get the software then read the help files.. if you want just email me the file and ill help tweak it for ya.

I did a little more reading up on other websites and it appears more folks prefer Westers tunes/pcms. For a guy like EscalonJon, this may be the way to go as opposed to the software (at least that's what I take from his last post).

So, add the price of HP Tuners software, a laptop (if you don't have one for datalogging) and the datalogging equipment (or dyno time if you don't get this) and you may be above $500. Plus, you get free updates for as long as you own the vehicle. So, if you add/change anything else that requires tuning in the future, Westers sends you another PCM (and you send them the core after you install new PCM). The website explains in more detail their core program for PCMs. This is just an alternative for folks that mod and don't want to tune themselves. So, for EscalonJon, who sounds like he doesn't want the hassle of the software/datalogging and/or dyno time, Westers may be the way to go.

Remember, I'm just providing info. To each his/her own.

You guys rawk...

Thanks for all the info. I'll check out some of the sites you guys "sited"(sic)....

It's nice to be in good company with people who know what's going on and are willing to share.

I'll let you know if I get any of the above work done, and how it works out.
