ok i will try to do another data log and try to get the cable and program to upload to the computer...

should I use the fast or slow rate of data???

Just from what I saw while driving....my LTFTS were around 4-6 i think on the top one.....the bottom one was less....

I just recently installed the diablo tune on my 2001 camaro ss A4. The car is running amazing!!!! I couldn't be much happier with the tune at this point. I might look into getting a custom tune, but I can't imagine it could get much better.....hopefully I'm wrong...LOL

I was wondering about what my ...

yep....it was the cable.....I got it reading 100.1% now, and the car feels insane......i've been driving it for 6 months like this and I thought it was pretty fast...I even beat a few mustangs...lol......but now especially with the diablo tune and now that the cable is right.....it feels sooooo fast ...

Is there anyway to test voltage of the TPS through my diablosport?

If not, can someone please explain how to check the voltage with a meter?

also what is the best cheapest meter and where can i get it?

Awesome, Thanks Rage for your help....this picture above along with your instructions help me alot! I will be trying this tonight(weather permitting) and I'll let you know what happens.....thanks!

Thanks Rage and Mike for your time helping me!!!

I've been having problems for some time now with my car not downshifting above 50mph but it will downshift below 50mph. Thanks to a suggestion by one of this forums members, I checked my throttle position percentage.

With the car NOT RUNNING, and the key in the "ON" position.....when I push the ...

ok i did what you said ......I did a log on the throttle position with the car off but the key on......the most percentage I got when holding the pedal to the floor was 79.22%.....It should be 100% right?

does this mean I need to adjust the throttle cable?

also I did a short log of the LTFT's on ...

I think my throttle cable could need adjustment although it doesn't make sense that it would downshift normally under 50mph. I've recently(in the last 6 months) replaced the following parts, so these can most likely be eliminated as the culprits for this problem :

All parts STOCK ac delco : Mass ...

yeah it downshifts perfectly under 50mph but not above, and yes I can manually downshift from overdrive into drive and it will downshift into 3rd. But even in 3rd when going over 50mph, it won't downshift any further(i'm not sure if it should or not)

I just installed the diablo tune on my 2001 camaro ss a4. It's already running alot better!!!!!

I had an issue prior to installing the tune of my car not downshifting to the previous gear when going above 50mph when I floored it. It's still not downshifting even with the tune, but it does seem to ...

Here is what it says on the screen:

Version: v.9r15
Hardware: UNIV_REV2
Bus: VPW
Born: 09/24/2009 9579
Bus Test: PASSED

Please let me know if this version is able to live datalog and recieve internet upgrades and hook to my pc.

Thanks!

I'm fixing to buy a used U7198 tuner.....

The guy said he bought the unit new in April of 2009. Assuming he's telling the truth(he has great feedback), should this be a newer unit that can data log and hook to a pc?

He said it is internet upgradable.....

i was looking at a tuner online for sale....the obd connector only has 3 metal pins....is this correct or are there pins missing?
