I had somebody ask me for these, so I'm posting them up here. The 1st one is for a 2500 8.1l 2 wheel drive Avalanche with 4l85e trans and the 2nd one is for a 3500HD(obs) with the 2 year only 8.1l...

From what I have heard from those who have done this is you just turn off the codes. The l31 tune only uses the cam sensor to put the engine into sequential fuel injection mode. Without the cam...
93/94 is the 1st gen 4l60e, 95 added a pwm solenoid to the torque converter clutch control circuit so they could apply it slower so lockup didn't feel like another shift. 96 changed the 3-2 downshift...
Are you sure on the operating system number? I couldn't even find that OS. Yhe 02 Escalade tune I have is a 2156 OS. I have an 0411 in the shop out of an 02 that I can try and check tomorrow.
If you have a p59 from a cable throttle setup, it can also do dbw. If your p59 was from a dbw truck, it most likely cannot do cable throttle as it probably won't have the IAC driver.
You need 2, 6 position dip switches. You leave the #1 jumper in place and solder the dip switches 8nto the 2-6 spots. And you must have them on both sides in mirror of each other.
If you're looking for a HD converter for a 4l60e, I got one from Suncoast many years back that has held up very well.
93+ 4l60e 4x4 uses only the speed sensor in the transfer case output. For 4 low the switch on the transfer case provides a ground input to the PCM pin to adjust the shift speeds. Not all transfer...
FYI, it's not cheap. Decent used intakes were bringing big money, last I checked new ones were in the $1500-1600 range, and use a 4 bolt throttle body. I did mine a few months ago, but that was...
I haven't run one myself, I just looked into it before we decided on a 7427 to run the trans. So far they have really good feedback. It's supposed to be pretty similar to the megasquirt 2, just...
Ideally a heated O2 sensor should be roughly 10-14" behind where the 4 pipes come together. If you get to far back the exhaust could cool to much to get accurate readings at low rpm's, but to close...
Have you considered something like running the GM single barrel tbi unit, then pick up a microsquirt controller to run it. They've gotten pretty cheap for the basic microsquirt controller, you can...
I picked up my obdlink SX cable for $20 off Amazon. Why mess with soldering over a $20 cable.
What did the os for the 02 come from? Theres different ac types and these tables are not mapped out or understood the best.
These are both from 02 C6500 GMC's with the 8.1l, but an AT545 non electronic automatic. You can segment swap them over for swaps using a non electronic auto(700r4, th350, th400, and so on)....
If you get me VIN numbers for the tune files you need, I can flash them in with my Tech 2, then read it out with PCMHAMMER for you.
Have you made sure your ALDL plug is wired correctly? I know early trucks ran the serial data to pin E where the later PCM's ran it to pin M. I ran into this on the 7427 swap I just did where I...
It would have to be from a 91-93 as the 4l80e controls were different in them than 94+. Have you tried checking the check engine light circuit with a test light to see if the ECM is commanding the...
I believe LS-Droid is working on adding in a segment swap option.
93-94 are the same, 95 is 1st year pwm lockup, and 96 changed the internal harness and reversed the operation of the 3-2 downshift solenoid. You can install the transgo lockup valve or make the pwm...
Somebody else tried changing the trans type, flashed ot in using pcmhammer, and it bricked his PCM. Tried it on another and got the same result. So don't change that setting.
Anytime you have a mysterious crank no start on a corrected firing order distributor cap, I always start by trying another cap. I've lost track of how many times I've seen them with fuel, good...
The harness change occurred mid year 93 because of all the leaks of the early style harness. The harness is compatible either way. I know you'll have to do some rewiring and swap your drac to a vssb...
I have an 01 5 speed .bin read from a gmt-800 with a 5.7l. rescale the MAF for the 75mm MAF that the gmt-400 used(gmt800 used an 85mm), and swap the VE table from the express van, and you're good to...
I almost went with the flex-a-lite fans, but the cost was just too high for me. I bought a brand new set of Spectra fans for an 05 silverado from rockauto for $142 + shipping and picked up a front...
