i need a tune! vs v8 turbo

[v8-tuning]

The reason it cant be tuned is that its using an auto 424 ecu still and there is no 2 bar tune yet.
So that's why no one can tune it with tuner pro just yet.
If you use a vr /vs manual ecu and harness not a problem can use 12p.
Otherwise kalmaker is the next option.

think of how much money GM spent developing the software to run these cars. how many hours holden engineers spent on the engine dyno tuning it for all driving conditions. its at the point where you can mod your motor, do some widebanding and VE work and it drives like a stock one.
some dyno operator with a haltech has no chance of rpelicating the drivability of a stock computer..... such a shame such a small amount of people are willing to professionally tune them

yeah I don't get this either.

I dunno if this will change anything or not but I have just sourced a vs manual ecu and loom. (Yes I found rocking horse shit!)

I'm guessing the looms will just unplug/plug in place of each other?

Is there anything else I need to do?

What the hell do I do about speedo and speed sensor?

[vlad01]

I also got one laying around in my shed, a police PCM. I never used it and opted for the 808 instead.

glad I did.

[v8-tuning]

Use a t5 or t700 speedo sensor that's all you need to change.
Its screws onto the turbo 400 speedo believe it or not.
The manual loom is a simple swap.

I thought the vn sensor was different to the vs one. Isn't one a Hall effect and the other is a signwave?

[v8-tuning]

No the vr/vs auto sensor is different its a reluctor type.

[moot]

So the dash/speedo will still work?

[VL400]

The dash gets a square wave sent to it so will still work, but might need a speedo corrector to keep it accurate. The original auto speed sensor is 40 pulse/rev, the PCM then sends a 4 pulse/rev signal to the dash. The VN ECU or VR man ECU can work directly with a 4 PPR signal.

once you get it all set up this tune should get it running its a std 5.0 with a gt42 turbo running 14psi.it has 42lb injectors. runs great but your turbo may make boost a bit earlier so its only a base. And if your interested this car with its stock engine making 320rwkw has been running happily for two years!!!!
