ok so i just got my emanage ultimate not to long ago with a wideband, i hooked it all up adjusted the AFR target map and its been running really smooth but pretty much every night when its been really cold it runs crappy when i got WOT it feels like its holding back and the car doesn't want to go thru the band.

if its like around 80-70's outside it pulls way harder, could it have to do with my new plugs i have been running ?? i recently switched to BKR7Es NGK's.

Oh and i am running CTSC on 7psi

 

any ideas anyone ?

 

Who did your tune?

 

The AFR target map is NOT autotune. I honestly wouldn't even use it as it gets freaked out pretty easy. You need to tune for temperature changes. As far as crappy: define crappy. Is it going rich, bouncing around?

 

sounds like a pig-rich running engine and its bogging from too much fuel. Cold = dense which means even more dense.

Who did your tuning at what is your AFR?

^^^^

EDIT...... posted faster then i could lol

 

yeah, thats very odd. cold air means faster...........usually

 

Cold air means lower intake temperatures which will increase the mass flow into the engine. Then add the extra fuel the car needs due t the decreased fuel atomization and together they add up to more than Greddy tuned for. I noticed that I needed to add more fuel with a cold motor and chilly ambient using the water and intake I/J maps.

i haven't been able to data log yet since the battery on the laptop crapped out but when i go wot it feels slow the rpm take longer then normal to get to red line it pretty much feels like im going like 1/2 - 3/4 throttle
