ok disregaurd those points but what your forgetting is when the engine first start before stft begins to lean the engine he says it idles fine with out surge and thats its not until then stft leans...

hey guys thanks for the replies,
low ve numbers in the idle area as a result to injector size i believe, how ever i have added more fuel from idle up to 100kpa in the lower rpm area since this file...

disabling stft ltft and removing closed loop temporaily is to eliminate any corrections interfering with his engine, smoothing timing at idle with value that high is not uncommon how ever all these...

i had very similar problems, i used the throttle follower with greater multipliers at 1200 rpm down to 0, and slowed follower decay,
numbers to high in follower will cause idle to hang just above...

i have reverted to previous version in order to keep my current config user defined formulas and what not, is this still the case with the beta version

i too want to know how this is rectified

disable ltft and stft and set closed loop enable to 141c tune idle with wide band to 15.5 afr, if you do not have a wide band there is a trick in a thread i seen on herre a while back which allows...

return your idle over speed and underspeed to factory,
with your cam set your idle advance to 28 degrees as a starting base and ensure your high octane table shows similar numbers in the idle area

has this engine been tuned correctly or is this an issue preventing it from being correctly tuned, are the symptoms responding to fuel,

in reply to matty b
i use a lingenfelter reluctor adaptor...

hey guys, i have tuned a handful of engine with various camshaft and cylinder work, strokers etc, as well as many other efi platforms such as haltec, adaptronic, autronic, motec to name a few,...

i have tried that procedure yes
i will post over there thanks

Vss is connecting and operational, vcm scanner showers 5km/h less than actual vehicle speed at 100km/h speed on GPS but wasn't concerned about this as I believe the difference wouldn't contribute to...

have tried making dramatic changes to idle spark tables,
completely duplicating main spark tables into idle tables, to ensure a smooth spark transition
this causes idle to hang a little at times...

hey guys, i have tuned a handful of engine with various camshaft and cylinder work, strokers etc, as well as many other efi platforms such as haltec, adaptronic, autronic, motec to name a few,...
