Hello i am New here and this is closest place i see to ask this, if i am wrong please let me know . I have a friend that has a 2000 k3500 7.4l fuel injected auto. Can this be tuned. I did put a new (used) knock module in it (Knock Codes). It did help some but motor is fresh with new heads and this thing is a dog he had a programmer on it but cant remember what it was and he sold it awhile back. Is this a em3494u pcm pcm # is 16208991, and what is needed if anything to flash back to stock or tune it please. Cant seem to find any info via google search. How can i read pcm like in ls droid or other free stuff i dont have HPTuners yet.

It will use the older "Black Box" Vortec PCM. At this time HP Tuners is your best option to tune this PCM. Many have upgraded from the Vortec PCM to the 0411 LS1 (P01) PCM. A Google search will point you in the right direction if you choose to do this upgrade.

Ok Next question this is a complete harness swap with 0411 pcm correct i think. Any sug. On donor vech for harness trk has 4l80e

I have a PCM from a 2000 Silverado 1500 2wd LM7 (09354896) that I flashed with LS Droid and OBDLink LX using a TunerPro RT modified BIN. I think the original OS is 16220610 (see photo).

Since I couldn't find an XDF for the original BIN, I used '01 C1500 LM7 os12208322 from a file found on this site and the 12208322 XDF.

The engine runs, but the tach output (PCM Red # 10) doesn't seem to be working. I tried a pull-up resistor without any luck. Would the different OS cause this issue?

The motor is in a 2005 Jeep Wrangler. The tach low puses were changed in order to get the Jeep tachometer to work.

In the tune, I changed Tach Low Pulses from 6 to 1 and Tach High Pulses from 6 to 1. Is there a Pull-up / No Pull-up feature in TunerPro?

Is there a BIN & XDF available for 16220610?

LRT,
Thank you for your reply and insight.

So, my 512KB 09354896 PCM with hardware 16220610 isn't compatible with 12208322 BIN and XDF? (BTW, is the hardware # 16220610 the OS #? Or are they entirely different things?)

Is this the BIN file you recommend instead?
2002 Chevrolet Silverado Truck Auto LM7 5.3L (12212156).bin
http://www.gearhead-efi.com/Fuel-Inj...9&d=1376283443

I should use it with your "Operating System 12212156 - 512Kb PCM - 2002 model year.xdf" listed in post #2, correct?

Will you help me understand why or why not?

Previously, I used this BIN
"'01 C1500 LM7 os12208322" with your "Operating System 12208322 - 512Kb PCM - 2001 model year.xdf" XDF from post #2 of this thread.

Will you please help me understand why that was foolish? My understanding was that 12208322 is "for use with 512Kb PCMs (Service Numbers 09354896 and 12200411)".
