Concerned and aggrivated

[Whippled 496]

Well...I asked the question of my GMH buddy.

Is this something that's actually used in the fueling of the Holden vehicles?


Acceleration Mode
When the driver presses on the accelerator pedal,
air flow into the cylinders increases rapidly, while
fuel flow tends to lag behind. To prevent possible
hesitation, the PCM increases the pulse width to the
injectors to provide extra fuel acceleration. The
PCM determines the amount of fuel required based
on throttle position, coolant temperature, manifold
air pressure, mass air flow and engine speed.

His reply.


"Yep, thats transient fuel, which is what I used to look after as well.
Its a horribly complex algorithm in our software, but the inputs are basically what was described there".

Sounds good to me....ROSS/PAUL can you go ahead and throw that table in there for us real quick?

Seriously...THAT....is what we need! Good find Justin, just hope something can come from it.

I really hope we can get this, but there are also other big fish to fry... T42 full flashing would be great and there are constantly E38 and E67 updates that really are beneficial.

I've asked for the transient fuel stuff 5 times over the past year and I know that if Ross had the time to get to it while still staying on top of the new stuff, he would have. Hopefully he'll get out from under the huge workload for enough time to hack the Gen-IIIs some more.

Any news/comments from Ross or Paul on this one?

yeah, a transient fuel table would solve alot of issues. I'm interested to hear about this as well.

any updates?

Some have been adding these calibrations as .cax add-ons. Look for that group on the forum.

Cheers,
