Ok thanks for that I have had so much trouble trying to find that info out

Can any one help me out with a wiring diagram, I have been looking and can’t find one , I’m helping a mate to try and sort out some issues with a VB commodore that has had an l67 conversion done. Does any one know if the pin outs for all the engine harness wiring for the vs pcm is the same as a vx D...

Can I get another Nvram chip or do I have to change/buy a new chip and adapter

I make changes all the time depending on track conditions or changes to the car

What happens when the battery goes flat in your Nvram
The one in my VX drag car would be about 10 years old and it did sit for a few years while I had the motor out of it
I’m a bit worried the car won’t start one day
