as for a idle afr i notice that my car likes 13 ish but whith head lights and fans full blast! this will ossuilate and my afr will tend to up up to 14.5 ish when this is happening (less power in the system) reason be because i undersized my crank pully
u shouldnt have this problem, anyhow how are u controling ur idle?? PWM valve? IAC? i looked at ur datalog and it seems that ur throttle postion sensor isnt wired or is wierd incorectly... i can see where u gas it up and the TPS reading stays same.... ur gonna want get that fixed up soon or later heh.... id almost recommend reburning code into megasquirt so u can get the orginal fuel map back? if ur VE map is all screwy then things will be that much more complicated, megatune dose come with a "auto tune feature" which works pretty dam well get u where u want... ive used it before and after i dialed in my fuel map and it smooths it out quite a bit!.... prety much ur VE%'s for idle should be same "roughly " for mild cruiseing at low rpm.... when u let off the gass and pull vacume (decelerating) ur map reading will go into the 30~20 KPA range) at this point of ur map u might want pull back of on the VE% by 10 or 20 % of ur idle VE %? follow me yet? then say for mild load ranges of 50~80 kpa ur ve% is going be to higher then ur idle of course maybe reaching 50~70 VE%'s but once u get on road always keep ur eye on the AFR meter if u have one or megatunes AFR gauge.... theres no reason why all of sudden u would lean or or go really rich, if u have a decent fuel map or even the stock one in megasquirt u should be ok! i wouldnt go any higher then 3 grand on the tach and cruise in high gears .... u should be able to putter down to a muffler shop
