Can you use a different OS? I think you are using OS 12225074?

I have some 6.0 Liter 24x files, mostly OS 12212156.

you also cant change the firing order in the software you must wire the firing order to suit.the settings above are for narrowband fueling with twin O2's and diaagnostics purposes

I haven't looked into the OS flash yet, but I think the Dimented flash tool allows for this yes?
Does the .Bin file include the OS or can i get that from somewhere else to run?
I'm not 100% sure what the OS is on the PCM until I download it and see.

I've got 2xo2 sensors and the harness has been repinned to suit the SBC firing order.

The attached .bin is from my daily driver 1999 S-10 pickup, which has a mostly stock 5.7 liter L31 / 24x / NV3500 power train.

I'm using the 24x crankshaft trigger wheel, 1x Vortec distributor camshaft setup, with 8 individual LSx coils. dave w

I just noticed something ... you using a 24x CKP reluctor on the SBC, and using a Vortec distributor for the 1x CMP signal ... are you using 8 LS style coils for spark distribution, or the Vortec distributor (with 8 spark plug wires) ?

I don't know for certain, but I had thought that to use a Vortec distributor to fire the cylinders, you had to use the Vortec 4x CKP system, and if you switched to a 24x CKP system you then had to use the coil-per-cylinder system (8 LS coils) to fire the cylinders.

Maybe someone else knows the answer to this ...

You are correct, in order to use the distributer to actually deliver the spark energy, you must use a 4x CKP reluctor and the distributers 1x signal along with the calibration file from a 2001-2002 van that had the L31 350 engine and 0411 PCM.

To actually run CNP you use the 24 CKP reluctor, Vortec distributer for the 1x CMP signal. For cable throttle, use a Camaro LS1 calibration in the 512kb calibration, for ETC(Electronic Throttle Control) use a Corvette calibration in the 512kb PCM.

Yeah sorry, I'm using the 8 LS1 coil pack setup, vortec distributor is just for cam position.

SUPER DAVE!!! Hello!! I'm looking for a .bin such as the 1999 daily you spoke of, yet I'm unable to locate that .bin. that seems like the 'Seg-swap' for my set up. pretty close to what I have, yet mine is all stock. THANKS!!!!

4x crank trigger?

Dave!! Hello!! Its a plain jane 2002 express van L31 and I am ashamed to say I do not know right off hand. I will look and find out. Thanks for the response. brb...
