Base Tune or close to spec tune for 0411 SBC406AFR-HSR

Anyone?

I've been away from the board lately.

I opened the the above .bin in my EFI Live software. I see you are using OS 12225074.

I noticed you are using a 24x CKP sensor. So am I correct you are using a per-coil ignition system?

I have a similar project, 406 SBC 4x CKP with a Vortec distributor. I'm using OS 12212156 from a 2002 Express Van.

I have the ability to Flash an '0411 PCM with EFI Live .ctz files and then read back the Flashed .ctz file as a .bin file.

Maybe you could post a modified EFI Live .ctz file you have setup for the 406 SBC, then I can post a .bin file you can flash?

I am unable to help you with TunerPro OBD II tuning.

Hi Dave,

Sorry I didn't get a reply notification and was checking through old posts.

That would be great if you could.
I'll try to upload it tonight.
I think if I can get the fuel and spark tables from your 406 express tune, and put them over the VX LS1 values it'd be a good starting point.

I think it might be a good plan to use a base LQ4 / LQ9 6.0 24x tune to start with. I recently worked with a SBC 5.7 24x system, which I modified a 5.3 24x flash to start with.

Oh ok, I'll have a look after work and see if I can find one on crazyholden.com or something.
Cheers.

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.
