Thanks for the info.

The crank sensor would be fairly easy and would have to lock the variable cam timing ...but a good project if my ecotec ever gets sad .

Would the VZ auto transmission be compatible?
They look the same .

I know this must have been covered somewhere but i could not find this exact approach . I have 2 vx's and 1 very low k vz . The vz is being slowly donored and b4 I make it un driveable I wonder if the alloytec might be modded to run on an ecotech pcm system . using the sensors from the ecotec modifi...

Is the hardware required for this just the cable in the case of these flash based models?

I could not find a clear answer as there are so many.

I have the same question .

so is it just the cable that is required ?

Does anyone have the details to open arrow engineering1 or engineering 2 mode?

Yes I had some success but the circuit posted gave much more consistant results .

I may have variables that are unique however,just reporting my experiences with almost bricking my cluster.

Here is the aldl citcuit that worked with Arrow ..other cables bought and diy were not successfull ...in fact they made the lights disfunctional perhaps noise? I supplied the 5 volts via the 12 v on the car aldl port and used a 7805 regulator . I used a usb to rs232 prolific cable for the computer e...

I managed to find arrow software and was able to reset the lights in the cluster to working .
Setting poll to true and a diy max232 aldl cable did the trick.

This seems to be missing so I thought it would be good to add it as i had to search else where for it ...I did not read every post so apologies if this is a repeat. PCM, Powertrain Control Module BCM, Body Control Module ECU, Electronic Control Unit, (generic term, ie. "Engine ECU") ECM, E...

Thanks for the replies Yes a v6 auto the problem is that the lights dont come on at all ...indicators work and the secutiry light flashes...but thats it ! I have got afew contact retailer on the lcd and the airbag (when i trigger it) diaplays on the lcd and chimes . when i fix the fault by reconnect...
