So yea just tried it yet again. Keeps saying the drivers off the cd or the ones I downloaded are corrupt. (Code 39)

I've uninstalled and reinstallled the drivers several times now. Like I said before when I go to install them it says they are corrupt.

It is a 64 bit system.

So I go to start my hptuners and this is what i got now everytime. Then when I go to install the drivers, it list them as corrupt both of the cd and website. Please help me.

I'm experiencing the same problem.

it wasnt a stage 2 tune though. the tuner obviously tuned it though like it was

thanks moosehead. world of difference. ill get a log up tonight and my new tune. i'm running pig ass rich now when i got wot, but now i've got like a 0-(-3) LTFT at any given point which i can live...

have a wideband. a different guy tuned my car before i bought hptuners for myself. i wanted to be the one responsable for my tune and learn how to do it as well.

mods: 2.7" pully, 60lbs, K&N...

So I can't for the life of me figure out why i'm running so good damn rich. My LTFT stays at -20.3 when at idle or when i'm at cruising. One person suggested bad o2 sensor which it very may well be...

quick question about the o2 sensors. why does neither bank 1 sensor 1 or senor 2 not show up when scanning on these cars?

2.7 pully, 60 # injectors, xtc header, zzp 2.5" catless downpipe, custum 2.5" dual exhaust, K&N Intake with AEM Dryflow filter, dual pass endplate, CA Heat Exchanger, and a 50 shot of nitrous. since...

i just brought home the tech 2 and it reset it that way

Does anyone know how to turn off the air bag sensor on a 05 cobalt ss/sc. i accidentally set it off one time when i took my seat out

im going to connect my wideband tomorrow, and upload a new file. any idea why my bank one would be reading pig as rich all the time? also at a normal cruise say at 65 mph, it bounces back and forth...

just be patient it takes a min or two depending on the size of the file to load

So heres a log of my car. Haven't touched it yet. Please let me know what you think i should adjust first. Also i have a service air bag on my car and was wondering if i could use hptuners to turn it...

guys the car just came out. a few months before aftermarket parts esp tuning is normal. hell if its really a few months that would be an incredibly fast time

your iat1 should be lower then your iat2. usually about 30-40 degrees depending on where you live. underload it can get above 200 degees fast. hence all the cooling mods out there.

well that sucks. had some info in there i was gonna use when i purchased hptuners. had some great questions answered by some guys

Mods since I seem to be unable to pm u. Where did my wtb: hptuners thread go? I know i didnt delete it

damn good info. what the hell do you have done to get a 13.1 in your redline.

nice. hoping to pick my hptuners up real soon. great info on this site.
