You don't "scale" injectors or a tune just for the sake of it. It's better not to unless you have to. In this case, you probably don't have to. Start...

Thank you for the explanation on the tool. So essentially, my tune still needs massaging to get it to the point where the VVE tool will be of use....

Now I see why you say that... somehow my tps, throttle position and pedal are all over the place ... wondering what is happening. Attached...

Thanks for jumping in, but to clarify—my PCM is a P01, and while it doesn't have the 63.5 lb/hr hardcoded IFR cap like the E38/E67, it does have...

Did you ever figure this out? I have the same issue. Random misfire but goes away with the MAF fail.

With HP Tuners not as of yet. I've used plenty of other tools for them to work.

upload your tune click go advanced in the bottom right corner, upload the file and the post.

I think you may be misunderstanding something. Unless you are trying to reserve the last row or 2 of your spark table for a "high boost" setting and...

The tune says it is from a 2007 GMC Yukon 5.3 1500 XL, what TB and throttle pedal are you using? Is it sourced from the same donor vehicle as the ECM?

No leaks. Interesting. The VVE Assistant doesn't really do anything for you. It is just a more advanced VVE Editor and you can use it to see the...

ok guys I spent the day researching and making the corrections Ed suggested. I scaled the injectors and other sections so I wasnt at the top of the...

Not sure if this is too late but hit up OJ at Fluid Motor Union. We can get it dialed in and you drive all the way back to Colorado with no problems...

i did not see the second page here haha responded to the same message again i just went over the tune file again there are 2 tables that do not...

Stupid mistake. Intakr and coolant temp sensors pins were bent. Fixed them and fires right up.

Can anyone please give some insight. New at this

Dang...yeah I was afraid of that. I may have to invest in the one you suggest.

Thank you Sir!

Plenty of companies out there that sell it

Good eye, gents. I live around 4,000' elevation. Not super high, but maybe enough to make a difference. I will split the difference between the...

yes, if you only have one PLX wideband hooked up to the red wire, you can delete the other two channels. then transform the MVIP2.1 channel from a...

I agree sounds like you broke the HP pump.

when you swap the ISS and VSS on these ... VSS will go up and down with engine speed. I have to diag that all the time with our swap harnesses. ...

I have a custom channel list from the tuner, so I am assuming that "MPVI2.1" is Input 1(red wire) and "MPVI2.2" is Input 2(blue wire) and I just need...

it'll say right in the channel list what its mapped to. read my first reply again. you need to transform it to convert voltage to lambda or AFR...

I just figured that out ;), but I can't find a matching name, so I need to keep digging to see what it is mapped too. Thanks for pointing me in...
