Why I hate VZ V6 ECUs...

[delcowizzid]

I did never try the trionic software in my car with pcm bcm and pim wired up I don't think then my openport cable had a choke fall off and its dead lol

Trionic works in and out with mdi

i tried trionic with my vcxnano and vz ecu and couldn't get anything to work.

Hit and miss with trionic and vcxnano

First time i got vxdiag to work with trionic i accidentally connected the ignition input through the led indicator circuit of a toggle switch

Here's a did read

pickapart vz ecu rerad.rar

i think that's just reading the PID's, you can get that with 1A read function. Write back with 3B. it's mainly just for VIN and ECU model and part numbers, software versions etc.

VIN is in PID 90

Does anyone know how to wake an ecu on a test bench that normally wakes in the car by jumping the starter relay?
Thanks

Its not 'waking it' but kinda just bypassing/manually triggering the starter which the ecu might be struggling to control if its buggered.

Hey tazzi
No throttle movement or humming noise
but engage the soleniod quickly ( even without rotating the engine) and ecu starts it's initialization process
How do you personallly get around this on a bench setup
Thanks

I've never had it not start up on bench unless completely dead (never actually warms up and amps draw shows next to no current)
Or you just get a no comms situation.

But just hooking all positives, ignitions, grounds and comms seems to work fine.
