VZ Fuel Gauge Error's
Re: VZ Fuel Gauge Error's
Ok thanks. It hasn't been serviced by dealerships.
If i was to buy a second hand ecu and send it off could it be done without the car?

Re: VZ Fuel Gauge Error's
potentially, if that is the issue.
Re: VZ Fuel Gauge Error's
normally you would program the IPC and PCM to be sure it matches.

ECU, never had a faulty clusterYou mean ecu? Or cluster?
According to chemistry, alcohol is a solution...
Re: VZ Fuel Gauge Error's
So that ecu wouldn't work in the car but ok on the bench?
Ive heard the alloytec ones are doing that.

Re: VZ Fuel Gauge Error's
I would suggest testing fuel guage sender unit resistance while its playing up.
VZ ls1 pcm fuel guage calibrations are normally for either 64 or 74 lt tanks ,if it had the wrong settings fuel guage still works but reads wrong .
The no start condition may have just been because of low batt voltage.

Re: VZ Fuel Gauge Error's
Im hoping that's the cause of the no start.
But the fuel gauge error I've heard to many horror stories.
Is the sender wired to the ecu?

Re: VZ Fuel Gauge Error's
Im guessing it does. Must be one of the ones on the right i can't see the description.
Must be a way of getting that info onto the BUS?
Surely the engind cal does not need that information.

Re: VZ Fuel Gauge Error's
There are 8 calibration modules on vz ls1 pcm, all the fuel guage conversion/config settings are in the fuel system cal module.
