hi all..

first of all, please donīt throw stones at me, for asking this again....

i still have part throttle and low rpm problems...

technical:

396ci, 10.6:1 comp, AFR195cc comp.port heads, single plane EFI, XFI280 cam, manual trans. 3.73gears

my problem is, that part and low hrottle driveability is not very good...

when the engine is under load, with higher rpms, than everything is fine, accelerates nice, takes tip-in good, no hiccups/hesitations...


but when driving with about 2000-2500 rpms, it feels, the engine doesnt know what to do...unsteady exhaust sound, popping, gurgling, etc...also with higher rpm, lets say 3000 and very light throttle, the same thing...

sometimes (seldom) when engine is warm, and air is warm, the idle hangs at about 1500 rpm and wonīt go down...

i really hope for help, i can send datalogs and .bin file, if someone wants to take a look at them!

greetings

Reinhold
