I am trying to download or even look at a tune in the repository and I keep getting the error message "Validation Failed". I am using a computer that has my approved HPTuners info on it, why is it...

It is a 2 bar SD tune and I agree it is probably lean at warm start ups. Where do I go to richen it at warm ECT start ups?

I have a 6.0 GTO with twin turbo's. I have run this setup for over 2 years and have always had this minor problem. When the car is hot or cold it starts and idles perfectly. But, when the car has...

Thanks for the feedback. The car was tuned after the install by a "reputeable" tuner and I have been working on WOT. Guess I need to take it back to the basics myself (VE tables) and get it right....

I am not sure why I would look at the VE table if at WOT I am getting my fuel through PE.

I have an LS2 with twin turbos, 15 gph 50% meth, 50% water spray, 9 lbs boost, using the MAF, 6 speed. I am aware that tuning on a dyno is generally done in fourth gear, however, that works out to a...

Got it, thank you.

I am sure it is in front of me, but after searching and looking for the answer can't find it. I want to purchase subject. How many credits do I need and how do I do it?

Thanks,

Mike

Thanks for all the feedback. I did get it to work and as I suspected in my first post I was doing something wrong. Inside the fold for the instruction for use for the USB adaptor ( we don't need no...

I have connected the LC1 to HPTuners Pro and done the calibration. I have the LED in line and it comes on correctly. My laptop does not have a serial port so I got an adaptor to plug it into a USB...

Thank you

Soundengineer, the nice diagram you developed and referred to above shows the heater ground to the chasis. Yet, three lines later you state ALL grounds should go to the data logger ground-no where...

Can anyone answer this or is it just a stupid question?

So, is the answer to this question: "Yes, it will work, but once you set code P0103 it will go into SD mode and not return to using the MAF until you turn the key off and restart." If that is the...

Russ and Scott, thanks for the info. My question now is how much influence does the meth inj have on ivt. I know this gets back to the relationship between IVT and coolant temp, but it would seem...

Guys, great discussion. At least for me. I have a Turboed LS2 GTO and the following questions:
1) Russ, you indicated to set the enrichment rate to it max of 4.00. Which table, my enrichment...

Yes, I applied the MAF patch and it stopped the MAF shutting off. I will be checking the AFR (I don't have a wideband at this point but will be upgrading) later this week (on a dyno) after changing...

Had the wrist surgery and it has taken more time then I thought to be back up and running. I patched the MAF, changed the PE enable and disable, and reduced the EQ tables (running too...

Thanks everyone for your input. Sorry for the lack of response and this short reply at this point but other stuff is keeping me snowed. I do think I have a lot to work with when I can get back to...

I now have both a tune and a log to share with the experts. The tune is the same as listed above. As you scroll through the brief log you will see two second gear runs. The first at 5 lbs of...

Thanks for taking a look at my tune. It is below. I have not saved a log (as I noted I am new at this) but will get one up as soon as it stops raining.

New to HPtuners and could use some help. I have a LS2 with turbo and seem to be limited by the installed 42lb injectors to 6 lbs of boost. When I try much over six lbs and reach approx 5200 RPM's...
