Thanks Brian! I'll look into that. Good insight 1project2many! I hadnt thought of the other issues!

Sure, you could do that. And it may work well. I'm thinking the transmission control code is fairly complex. So what happens if you disable all...

In the first 4L80e (1991) It used a thread in trans temp sensor. I would think It would be the proper sensor for what you need. ...

howdy, and welcome!

just a thought..... if i leave all the tables the same and use a bench setup to determine what temp the ecm "thinks" 160 degrees is. (lets say when...

I have a tiny bit of information about older Vauxhall controllers. I was very interested in the 1.8 and 2.0 variants. If that helps I will see if I...

Hello, I don't have that whipple bin, would you mind emailing it to me at efisystems at excite dot com? Thanks

If the speedometer uses an A/C signal you should connect to both VSS wires. In order to use one you need to connect the other to ground. The pcm...

Well, there's some good news and some bad news and some good news with work. The good news is that the coolant temp, air temp, and transmission...

Thank you. I’m messing with a 2006 truck and have read that bin. I’ll be adding it under the 2006 bins. As far as I’ve read, the only public P59 xdf...

it is basically the same as the 16197427 (it uses the same xdf and adx files) as a matter of fact, the bin i am using in it is a 16197427 bin. it...

If it uses water temp you cant do anything. Cooling after engine temp is the most important. Aldl file maybe you can change the values ​​for...

Is this only for trans fan ?? You cant change parameter in editor this is what ecu use.

This one was hard to get. No current files I have, got the p/n of that bin. It will be great if we can build a better 7603 library of bins. ...

Success! The addressing was off in my TunerPro. After getting the settings correct, it works! Thank you for helping me make sense of this thing....

this is the chart referenced in honken's post above.....

Great info!! thanks much... just so i am not about to mess things up.... this is where i would adjust things correct? edit to say i...

Okay you can set temp. found this https://ls1tech.com/forums/pcm-diagnostics-tuning/1084125-4l60e-temp-vs-resistance.html

i am not explaining my issue properly.... the trans temp is input to the ecm on pins b4/b5 in its stock form. the oem temp sensor for the ecm...
