Any 1998-2001 Vortec 454/7.4l L21 calibration in Kodiak 4500, P30 van, Workhorse etc etc. This uses the dual 80 pin connectored PCM's 16232148 and 16238212 and OS 9354781T, 9369651T and 9384681T

This is a VIN for a 1999 GM P12 chassis on which a motorhome was built. It uses a non computer controlled Allison trans. 1GBMP37B2W3311219 I just listed this VIN for access, I dont need this particular vehciles calibration per se.

Thanks in advance

That's a rare one, can John at TunerCat get one at last resort?

i assume he could access one if you give him a VIN as he's got the GM discs.. Just thought I'd try here 1st so I didnt have to pay the $25.

Thanks

Here you go.

Thanks a lot Jeff, thats cool to have that calibration. I see that its a "D" engine code, I think that means its a natural gas engine IIRC.

That calibration has 4l60e values in it, but under trans calibration, 0=4l60e, 1=4l80e, 2=Manual are the choices, but #3 is selected. I wonder if the full manual version of the Allison is being used? AT-542(MT9)??

Engine Identifier is set at ZERO and there are 8 choices, ZERO through EIGHT.

Speed limit of 78mph, with a hysteresis of 2mph.
rev limit defuel in P/N at 4400rpm, refuel at 4200rpm
ETC throttle limit 3750rpm
ETC speed limit 75mph

thanks again Jeff.

That one had the Allison Trans in it. That tune was not mine. I got it from someone a few years ago.

I do believe Gearhead-EFI is now our "Monodax"----The go to place for info.

Jeff

I agree.

Ive always been interested in using some of the Medium Duy truck options such as Fast Idle which needs the fast idle switch and fast idle indicator lamp. Then there is the PTO idle speed which requires a specific PTO switch.

Fst Idle switch 15957294 $18.20

Fast Idle Indicator Light 15025093 $77.48

PTO Control 15737895 $124.90

With a dual 80 pin PCM and the appropriate calibration we shoudl be able to use a fast idle switch.

Lotsa cool stuff once you get out of the black box PCM.
