Brand new "bricked" VZ V6 ECM's????

[VX L67 Getrag]

No worries at all, happy to help!

I don't have a tech2 but when I had a knock off & did some tis2web testing I think I could change the vin & get tech2 with access to change the calibration from memory. Which would save the $120 odd price for tuning software licensing, if it is possible!

Which tool was able to talk to the 'bricked' pcm? Hptuners?

[Gareth]

Hi antus,

Im sure VX L67 Getrag will respond to confirm but yes, Hptuners is what was used to get the pcm going again.

But just to clarify by 'bricked' i mean that the factory prescribed method of replacing the pcm will not work, (tech2 and tis2web) so i may be off with the title of this thread seeing as it now works with a different method of programming.

Can't wait for the next VZ to be towed in with 'Low fuel' lit up on the IPC to test the pcm on

Cheers.

I had a VZ V6 once that randomly did that. And one of the oxy sensors never displayed a reading (with tech 2)
End up selling it (traded in) to many expensive and stupid problems. GM really failed in many ways with the VZ.

I haven't struck many electrical issues with VZ's as yet, but yeah failed in the sense of trying to stretch service intervals out which in turn causes the oil to carbon build & then stretch timing chain or cause tensioners to seize!

But yeah hpt read/wrote to it, was a very weird file originally on the controller with an extra weird op sys number which means you can't just do a write calibration as none of them are compatible!

sort of on this topic... does anyone have any dead VZ v6 pcms that are no good for running an engine but I can hook up on a bench to develop a CAN based AVT 852 ADX? would be so much easier that way.

[Gareth]

Yes, drop me a pm and i'll send you some..

Except with the drewtech and holden bin aldl does not appear supported under tech2win

This is a real pain here if one wants to diagnose any errors or problems on the older commodores!
Is it a drewtech limitation or a tech2win limitation?
Would you recommend the Mongoose over an MDI (If there was an MDI that actually worked..)

Also.. those subscription prices.. wow..
I guess the yearly subscription isnt bad.. if you look at it in a daily cost. Roughly 3usd per day. Instead of $18usd/day for the 3day access!

Can't wait for the next VZ to be towed in with 'Low fuel' lit up on the IPC to test the pcm on

The infamoous low fuel warning, power error and SVS error. I cant believe how often VZ ecus just shit them selves! Has anyone ever actual put a temp sensor on the units?
I have 3 or 4 VZ ecus here, all of which apparently dont work in car properly causing the above issues, except communicate perfectly on bench allowing for full reads and writes!

Biggvl, did you end up getting a Mongoose cable?

Yeah youll defnately need a ecu or two for testing! Impossible to develop anything without one in hand.

Sorry tazzi, after VX L67 getrag showed me that hp tuners gets the job done, I've done no more about it as I have hp...

I think in the future I'll go for drewtech for the work shop updates for newer cars, seem to be a more professional setup, I wish there was a better way...

Also, I've never had the thermometer out but I've removed plenty of VZ ecu's that are too hot to handle!!! I believe that mounting of ecu's to any engine is a shit idea not matter how well sealed/ip rated/heat proof the engineers make them, no electrical board can possibily last that many heat cycles and not begin to faulter. Id love to hear a good reason why they did it...

On the other hand if holden didn't engine mount rodeo, astra and commodore ecu's, then Id probably be out of a job

[Tazzi]

No point spending more cash if you have something that already works!

I just find it so weird that the ecus I currently have on bench, are ecus that the scantools apparently couldnt communicate with and needed replacing with another unit. Yet, my tech2 and ELMs happily talk all day with them.
I know its out of the car, but didnt think that would be an issue.
