Striped down vx tune

[pas94]

one other question about the check sum does this cause any issues when changing the settings?

It does but the info on that in the FAQ links is based off using the flash tool and flashing through the comms port. Burning straight to the eprom I've never done.

Yeah your in uncharted territory there. If you've socketed the flash you could almost go nvram. No reason it couldnt be done but how you have done it is so rare i dont think you'll find any realtime code for a modded flash pcm. Might be best for you to get another stock pcm and use the normal flashtool which will update the checksum for you at flash time.

Right so I've called to post office to see if they can retrieve the package out of the post as I sent it 3 hours ago... FML
So I need to find a new PCM. How compatible are these pcm, I know the ecotec has been around for ever so will any pcm work, plugs sensors all the same etc? Whats the easiest to work with I have an eprom programer if needed and an aldl cable.
Don't want or need real time just want to disable the vats and have the thing run... !

Wont need a eprom programmer for a VX PCM. VY is the same PCM.

[pas94]

Would a vt or vs pcm work?

[Dylan]

With the matching engine loom yes

If you're in a hurry I have something here that could help out, PM me.

I think i have had some luck with this project, I picked up a vy pcm from the local wreckers, it had a chip torque sticker on the side... inside the flash is socketed so hopefully I can copy it to the other pcm with my eeprom burner and save that pcm giving two working ones as well as an aftermarket tune. I might even try use the flash tool and the new pcm to program the stock to one chip. so they are different.
Any one interested in seeing whats on the chip torque tune? I'll post it up once I have it off.

I'd have a look a it PM might be the best incase of any copyright issues.
