Final drive for now is 3.73:1, (planning to go 4.10 in near future), Tires are 275 70/17" BFG KO2. After fine tuning tire size widget, in 3rd gear with Torque Converter locked, 2000RPM=52mph,...

UPDATE!
Short version, ordered a custom built 4L60E WITH Engine Braking built-in, (only effective in the lower gears, not 4th), trans is en-route now from PerformaBuilt to be delivered in 3 days....

Thank you, what a wonderful tool that is, had no idea it was simplified so, didn't think to look under the drop down menus, (slap forehead), that is SO much easier.

OT Tangent...
Is there a page...

Where's this "calculator"? Trying to adjust for new larger tires on 01 Burb 411 PCM. Recently updated the software and the original simple tire size input is gone, now just a couple windows with...

Little more research reveals that mechanical internal workings of the 4L60E, (and others), are different for PCM requested gear selection vs shift lever gear selection in regards to how and when...

Hmmmmm.... Is there a work around to fool the trans alone into thinking that the throttle isn't closed when it actually is so it will avoid the "Coasting" protocols and actually shift down as...

Want to incorporate some engine braking on drop throttle down hills, nothing crazy just some amount.
Short version; Only at ?closed? throttle does the PCM not shift the trans as programmed, any...

Thank you Bill.

I did e-mail support and within 2 hours received a response. Really nice to see the Customer Service at HP-T is genuine and prompt, THANK YOU!

I found the issue, I "thought" I...

Dead thread revival...

Just swapped laptops, now using Win7 ultimate. When asked for my MPVI KEY, pretty sure the KEY I entered was the latest KEY from my last purchase of additional credits....

WOOO HOOO, Success, well mostly...

Short version, can the Mac users among us direct me to the path I...

I did find that the VSS itself can be logged as a PID, setting it up/configuring/programming the PID to record as miles or feet is beyond my ability.

Searched and didn't see anything regarding being able to monitor/log distance traveled. With the .001 resolution of time in the logs, being able to log distance from the VSS could make for quasi 1/4...

Correct. I have not paid close attention to IAT mounting over the years, though I think GM and other manufactures are no longer installing IAT/MAT directly in the intake manifolds of vehicles with...

Of the open element GM IAT’s I have tested, (testing for sensitivity and response time/lag), I did discover a slight difference in response between the brass housed IAT and the plastic housed...

LSxpwrdZ,
Were you able to resolve your IAT correction/heat soak issue?

Cracking open a cold one. :crazy:


Anyone playing with this or a variant of such?

Yes, it is confusing, two separate clutch switches, (in one physical switch), two separate brake switches!?!? :shrug:

No biggee, using the BMW pedal switches and a couple relays was able to mimic...

Yeah,
I my study of the schematics, it is one physical switch with 2 separate electrical switches inside. One for the Cruise module, the other for the PCM.

Thanks for the info. May have to get...

For Gen III LSx conversions with '99-'02 PCM's cable TB, using GM Cruise control, what exactly is the PCM doing with the "Clutch Anticipate" Switch, (the one that goes to pin 32 of the PCM, Blue...

Thank you. I noticed that but didn't think much of it withe throttle closed and the TPS reading 12% back then.

Today I went out and drove it around for a while with HPT scanner running paying...

5 days later, no more idle swing issues, runs, drives and idles perfect! :yay:

I am not 100% sure what fixed it, though it was either the cleaning of the IAC or the new alternator.

One other...
