i've noticed that when i did a parade i drove about 5mph for about 10-15 min. and the car started running leaner and leaner and started to act a little funny... is this because of heated fuel or a hotter/heat soaked motor or something else?

is it normal for a car to use more fuel when it gets hot? or is the motor saposed to use more fuel when its cold?... just curious... i know a lot more FI guys will experience this than a NA/n20 guy would....

note* that i do have a 408 with d1sc, sheetmetal gas tank, big magnafuel pump, single ati fan, EWP, FMIC, stock rad. , fuel pressure is set at about 55 at around 16'' vacuum, and a 1:1 FPR


thanks,

Tyler

more heat = less effiecient = less fuel.

Something in your tune most likely,

there is a table for modifying a/f based on ECT and IAT

ok i just wanted to make sure thats normal... i know where that table is i just never had that happen.... i'll adjust accordingly

what about on start up... i have the car idle at 700rpms but for about 15 seconds i have to help the idle with my foot until it gets about 100ect...

i do not have a IAC and i dont want one... is there a way to help cold start with out it... if not i can live with it.... damn IAC...
