help! E67 enabled flex....

[AGRO]

Hi all,
I enabled B0178, and the mil to suite, wired in the flex sensor, car wont start!
when I disable B0178 starts and runs perfect.
The car in question is a 2015 HSV GTS LSA OS:12656942.

Did you test the sensor to make sure it works... I'm not sure how to test it, I would have to dig it up in the service manual.

[AGRO]

Its not a sensor or wiring fault.
i enabled b0178 on a stock standard car, same issue won't start.

Do you have a Flex Fuel sensor fitted? You know on the LSA (I'm guessing) probably none of the E85 tables have been configured from factory.

[AGRO]

Yes, everything is configured. The flex sensor is reading perfectly with ign on. But car won't start. I have done this exact same procedure on e38's, never an issue.

[AGRO]

Any other ideas?

So is this still with regular fuel in the tank and the sensor is reading 0 % ethanol?

[AGRO]

Correct.

And when you tell the calibration it is not flex fuel the car runs fine? I am going to suggest that there is some underlying calibrations that Holden never set up (given the LSA was never intended to run E85), therefore it is defaulting to a state where the engine will not run. There has been a number of GM calibrations like this on the E67 (the Cadillac Northstar is one of them), unfortunately there is no fix as such.

[AGRO]

Exactly right.
Perhaps a calibration from another car may work?
Do you know any E67 that had flex fuel enabled?
