thanks, I appreciate the response

Picked up a "built" and "tuned" 6.0l swapped C5 a few weeks ago. ran real well when i got it but HVAC wasn't working. I found that when they installed the engine they never hooked up the vacuum line...

I tried cheeping out by not getting the "pro" version when I started out. Tried EGR couldn't get it working right, and then serial that sometimes worked well then sometime it wouldn't. Ended up...

Thanks for the info, I have been having serial issues as well. But it was weird because I was not having an issue then all of a sudden one day my WB started disappearing. I will try your solution.

Local airports post actual KPA for pilots thats what i use then adjust my MAP koeo to match.

yes if thats the sensor you have

Take the Part number off your map sensor. Search for the data and offset. On your engine> Airflow tab you will have the spots to put that info.

You could try to take your Flow Rate vs. KPA and multiply the whole table by 0.95 in steps until it starts to act right

I would look at your MAP scaling.

never mind fixed it

for some reason after i went from 2bar to 3bar os now for the life of me i cannot get my VE scans to work. I have tried Beta and even deleted the software and reinstalled.

I am using 3 on my 5.3l swap with PSI harness and LS1 P01 ECU. Tried 6 like suggested and it was double the actual RPM. Autometer suggested using a resistor which didn't help, So I just changed the...

Do you know if I raise the KPA up 15% then lower VE by 15% Does that even itself out?

Cold start has always been an issue. I didn't change anything from stock startup wise that I thought. just failed MAF and disabled OL and CL. I do see that the VE seams high, Like its over...

My monster is stating to come alive. VE tuning seams to be going well. Numbers are looking good. Starting to feel some boost coming on. If someone could look at my last log and tune I would...

The tune I posted is factory stock off my truck

here is mine, 06 LBZ

ok got her going a few days ago. It was the MAP sensor. When I originally googled the PN for the MAP i had is had said it was a 3.3bar but I guess that wasn't the case so thanks 5FPD for that. Been...

here are a couple scans i got this morning one is the crank no start. the second i decided to pull out the MAP to and put 20lb of shop air to it to see the changes. then switched the sensor three...

yeah its kinda irritating. I will try to get a scan tomorrow I need a break. was working on scanning today but my Wideband wasn't working on the scanner for some reason. Thanks for our help

I put a 3bar in when changed os and the generic data seamed to coincide with the sensor data

Ok this is really getting frustrating. installed new PCM and installed the 3bar OS then copied the stock VE tables followed all the guides and now wont start. tried to bring up the VE and also down...

thanks, fortunately i have another LS1 pcm was hoping that I didn't have to license another.

Thanks for the response, is their anyway to change that? or do i need a new PCM? This PCM was in the car when i bought it from an impound auction. Im running boost so I wanted to change to a 3 bar OS

Under my operating system tab their are no choices.
Does anyone know why and what can I do about it?
