As the title says ,I have confirmed with external temp sensor and remote sensor in the pan ,that the gauge and scan tool read the temp about 15 to 20 deg higher than actual. Is there a way to reset...

I know this is old but it is a question that I have.. I just Need one clarification; When the BE map threshold is reached does the TPS matter? Will I go into boost enrichment at The set map...

Thank you for pointing me in the right direction. I found where the error occurred. In my original idle tuning it appears that I inadvertently had my graphs settings in Celsius and then pasted them...

Thank you, that helps i will do that in the morning.

I appreciate all the comments I didn't want to turn this into a huge thread. I was just hoping someone could direct me to the parameters that control the idle during the temperature ranges I was...

Open loop short term trims are disabled, but ive tried it enabled with no difference. The problem occurs in open loop before 131 as well as closed between 131 and 170 which is where i have the...

Thanks ill check this. Its new but ive had a lot of new bad parts

Thanks for the response. I think i got a good idea of how all the systems work. Im just a little confused as to the warm up period. It seems to be, "handing off", to different tables as it warm...

Can someone explain to me what controls the idle from cold start until the temperature that is set for Adaptive idle learning. Is there a reason to not set the adaptive idle learning temperature to...

I think I have a grasp on how the fuel injection system works I just had a quick question about the short pulse adder. I understand that the short pulse adder will be added to the pulse width once it...

Yes, thanks for the response. It turned out that I cannot change an operating system from a previously saved and flashed tune. I had to go back to the original tune and build off that to flash a...

I just upgraded from MVP1 to MVP2. I then downloaded the latest version of editor. I no longer have options to choose the operating system. Any help would be appreciated.

Thanks for the info I guess I'll be upgrading.

I just bought a new laptop with windows 11. I downloaded the latest VCM Suite and drivers but when i try to resync the interface nothing happens. The computer sounds that it knows the cable is...

I just bought a new laptop with windows 11. Now my MVPI pro interface is not recognized. Ive downloaded the latest version of VCM Suite and the drivers but nothing.

If my adaptive idle learning temp is set for 150 deg, After it learns will it apply the modified idle to temperatures below 150 on subsequent cycles? Is there any adaptive idle corrections under the...

I did not know that, thanks.

The more I thought about it im not sure if this is a bad thing. Ive been running this big truck hard since 2003 with a turbo SD tune and with the trans set this way. ...

I really appreciate the input and Ill give your suggestion a try. As far as the transmission; it shifts firm but not really hard. what does disabling the diag codes do?

I did find and article about this and found the math to determine the min fuel in transient. It was different from what I had so Ill give it a try.

That's what I thought but its not detonation. I crept up on this timing and the soot never changes. I've reached knock and backed off. The motor runs strong with this timing. I started with 25 at...

I have a 2002 2500HD 4x4 with specs below. It runs real good and the Lambda numbers on my gauge and logs seem OK but when I mash it on kick down I get black smoke out the pipes. The pipes are...

So I did turn this off and it worked perfect thank you. I was just confused as I got some help from an labeled "advanced tuner" on this site and he told me to leave it on.

Wouldnt this just disable STFT entirely? Or is this just for open loop?
