Kind of a related question... HPTuners gives me an error about not being able to access files (for example, I can't open a .cfg in under Program Files\HP Tuners...). This is on Vista. Is there a...

Yep, that's exactly what I did. It took care of it! :)

Thanks!

I noticed SP1 for Vista caused some problems. I could always run HPTuners OK until I loaded Vista SP1. Now it won't recognize the driver for the MVPI USB interface. :(

I will try setting the...

Got it. Thank you!

I have decided to go MAFless and try the 2bar speed density tuning (11lbs boost). My understanding is that I need to purchase a 2bar MAP sensor and IAT sensor. I have HPTuners and will upgrade it to...

Can anyone recommend a book or two that would help someone new to tuning to learn the basics and beyond? (specific to LS2 would be even better) I would like to learn more about speed density tuning...

Ya', we are going MAFless and speed density. This is all new to me, so I'll be relying on my tuner.

Thank you!

I am trying to add Mass Air Flow (hz) to my gauge display. The largest value I can enter for Max is 10000. The same applies to Alert Upper. Is this a current limitation, even with the patch? ...

I'm putting in 60lb injectors this week. I have a maggie running 11lbs of boost and meth. Can anyone guide me on what settings I will need to tweak? I am assuming that I will need to modify the...

So can I / should I change it?

I have a 2005 GTO with the factory LS2. HPT shows a Cylinder Volume of 0.70819 L. This gives a total displacement (x8) of 5.66552 L. Shouldn't this end up at 6.0 L, or 0.75 L for Cylinder Volume?

Wouldn't this be listing MAP in PSI? MAP isn't necessarily the same thing as boost, is it?

Is there a way to convert MAP to boost? I have an LS2 with a Maggie supercharger, and I would like to display boost. Can I calculate the boost based on the MAP? I was reading through...

Will this feature be supported at some point in the future? Any ballpark ETA?

Perfect!

I wrote the exact values from your screen cap. I then read the settings back in, modified the wheel and tire size, and wrote it back. It was within 2 miles per hour. I then tweaked VSS...

So if I don't have those values? :)

I believe Magnuson made that change. I am guessing they had the previous version of the software, hence the problems.

So what can I do at this point?
...

I tried that. No go -- I'm back to it being off. Doesn't it make a difference if you have the manual versus the automatic?

When the software calculates the tire revs / mile it comes up with 794,...

Here is what was there before I changed anything.

Where is the calculate button to which you are referring? Is the commit button...

I do not have the option to "Tuner Lock" under Calibration Details. The image below is what I have.

I am not a professional tuner,...

I am having problems getting an accurate speed on my speedometer when using what I think are the correct values on the Speedometer screen. I am probably missing something simple. I have a 2005 GTO...
