Use the 12P 111 XDF. Google wide band O2 sensor.

I'll submit my tune I'm running in the L67 T5 VK

You can see the large number of changes in the change log.. and a few little notes to myself.

Its experimental. Since I run a 10psi pulley I decided on the knock history to lose the high octane table.

Living in the bush means I can't always get 98 BP juice... usually yes. But on trips your lucky to find 95 sometimes.

Simple theory is, run a bit less timing, loose stuff all HP, protect the pistons- we have more boost anyway.
And stay at full advance without knock rather than pull timing during when I need it.

The rest of the changes are essentially copied over from a VS BWLS T5 manual bin where it looked obvious.

Some points to note.

VATS Disabled
Manual Transmission Option
Fuel Pump Speed Control Disabled
Low octane table copied into high (Similar to most vs tunes it seems)
Many flags changed to BWLS
PPK 6250 pulses /Km http://pcmhacking.net/forums/viewtopic. ... 983#p53983
Feedback welcome!

What's the reasoning behind turning off the fuel pump speed control?

There was no need to install the speed control box and wiring for an arbitrary feature. The VS SC pump installed directly into the vn wagon tank & sender/plumbing I fitted to the VK wagon.

So I turned it off in case there was some kind of code dependency on dual speed operation. Useless thing anyway even the factory dismissed during VY.

The fuel pressure never seems to exceed 60psi- which is under the FPR and return line flow limits too. So All good.

Cheers.

1st time post. (Being reading site on/off for a 2 years now.)

Is it ok to post up a C.O.M.E bin here ?
Hand written on the sticker was HV266C.

Welcome,
No due to c.o.m.e copyright laws.

Cheers

is there something you want to know about the tune or just wanted to share ?

Just wanted to share.
I don't run the tune, its just a spare memcal i have lying around.

Correct. Thanks for thinking of us but I have checked with C.O.M.E if they mind old tunes being distributed. They requested that we protect their copyrights and do not post those tunes. Their logic is that too many people with no idea get hold of them without knowing what engine the tune was created for and ring up for support. They dont want the phone support overhead and their time wasted.

Whats with the "Number of Engine Cylinders" scalar in the following BINS - as (very much) a noob at Delco hacking, is there something I am missing?
