Just what i do to see how the trans shifts then add it back in as needed.

why would you disable torque management? i see the changes you made to the gear ratio & tire calibration just curious why that was done before i...

I believe you need negative numbers in the minimum spark table to go along with the negatives in part throttle.

I can get the ECT set up on the column axis but apparently there is some formula for the other axis that is not easily input. That is the reason for...

go to airflow then electric throttle then opening rate and make that chart 100 everywhere for a better throttle in 1st gear

Are you referring to 3-5% 0n fuel or air? Here is what you asked for.

How often do you see that reset? Surely not several times in 10 minutes. I cleaned the TB and IAC port. IAC is at 0 and idle is a little above...

Could try bumping up the Speed Control Reserve (Idle > Torque) to get rid of the RPM dip. Not sure if that's the fix, but I recently had an issue...

occasionally they will reset LTIT and STIT back to zero. Just like fuel trims will reset to zero by themselves occasionally. That sounds like the...

ive only heard of O2 tests

What transient changes did you make

Definitely I can support you. Share the tune and log.

Post in the GM v8 Gen 3 section so the GM people will see this. Some of the GMs have a fairly complicated control scheme for the fan control. The...

You need to be logging TPS% so you can see what your throttle is atually doing.

I think i got it! The E85 and transmission changes seemed to help a good bit. here is the new tune file and log. It was either the gas or the rain.

OK just wasn't showing up on the mobile version. Here is my stock file. Any help on PATS delete is greatly appreciated

gtstorey Thanks for the help but you've lost me? New to HP tuners. The original file did not have electric fans. 2002 Silverado 2WD 4.8 This is...

Need help. I can't make the histogram graph work for the airflow #'s, BRAF. Tried Russk airflow.cfg files, will not open. Most likely I am doing it...

Need PATS delete for 2013 Mustang Coyote swap into F100. Other problem is I can't seem to find the attach button to upload my file. Maybe it's...

Hey everybody. New to HP TUNERS and obviously the forum. WNY area. Been wrenching for 30yrs. Probably programed a thousand ECUs from all makes. Never...

Go to the particular section that covers the vehicle (ECM) that you are working with and post there with details of the build and you stock tune and...

Have you checked fuel pressure?

Well.... I managed to read it, save the file and make my temperature changes and write it to my truck. I switched to the VCM scanner and started...

Your VE needs help, but id start by failling the MAF and tuning the VE. moveing the VE without failing the MAF ususally doesnt work. fail the...

Thanks for the reply. I figured this was the way to do it but better ask than screw things up!

I really dont want it banging on the rev limiter the whole way down the track. I think I can get Torque management to use the ETC to cut power.

I currently have the 07 ecm in the 08 truck, but the security light is on, and I got a no crank no fuel prime. So something isn’t jiving with the...
