Transient fuelling????
I've been searching here and on the net in general and it seems HPTuners has some sort of 'transient' fuelling tables.
I know GM uses these in their tunes.
Any chance we're going to see the same in EFILive...Paul???? Ross????
I hate seeing my afr guage peg out max lean any time I touch the throttle.

YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
DUCT TAPE.
IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

google the topic. all you're gonna find (that's worth your time) is patent applications and phd thesis. not an easy topic. any enlightenment in this department is greatly welcome
.I have heard about xtau fuel modelling which is supposedly helpful in theses circumstances. Whether this is a table in the LS series of PCM though is another matter entirely.

Howard your on track with this one.
As you know the algorithm behind this is quite complicated.
Marcin you would be happy to learn that the tuning software that GM use "Inca" has a portal to Matlab and other proprietary software to calculate these transients.
This will be no easy fix for you as you will require inside information....you know what to do...keep pushing for more information +.

PS: That intercooler will help!
Rev it up, Drop the clutch, See what happens?
Hi Mick,
I was just talking with my GM buddy (he dropped in to show me the Pontiac G8 GXP he was putting around in).
He was really surprised we didn't have transient fuelling abilities.
He said they have the ability in their tuning to dump a heap of fuel in...in block form at tip in. Can't recall what he called it (block dump I think).
The intercooler has become necessary...even on a 15oC day I'm cruising at 45o IAT's and easily get to 60oC if I give the throttle a tap.

I have added in the settings you guys want for the E38/E67's, LS1 will follow soon.
Cheers,

I no longer monitor the forum, please either post your question or create a support ticket.
Ross.....you absolutely ROCK!!!!!......(how soon will the LS1 tables be done).

Great work Ross..
looks good, but does it come with any explanations?
