Updated the first post, has been tested and is working fine.

I have a VT V6 Ecotec series I which uses the $A5C variant in the original factory memcal.

If I replace my memcal with an nvram loaded with the suggested bin ($A5G 3.8L Auto 16233396 ECU Series II Update, ends 04/2000) what will happen?
Will the car run? better? worse? will the other modules on the bus (BCM etc) recognise the upgraded PCM?
thanks

It should run pretty much the same (I dont think there were changes in the VT that meant an early release had to be used) and all other devices will still work fine (they wont know any different).

If it does require A5C then I will mod one of them and you can test it

vt s1 running s2 tune normally wakes them up a bit should be fine

Thank you.

I guess its time I finally bought the NVRAM and USB comms devices.

Are they still available?

The NVRAM is available now but the USB comms have a short wait - I would expect them to be ready by the end of next week.

hey guys
ive modified my adx and used the injector voltage for my Wideband. seems to be all setup but i am having problems finding the voltage monitor line.. would D16 be the pinout i need for the wideband??
thanks
btw VR V8 Auto

dont think that trick works on vr only ecotec vs

i think it was mentioned it works for VS V8 Auto

It does with a modified bin, have added it to the first post of this thread. Pin D7 is the feedback line.
