having some really wierd problems with boost, i dont really understand why. When its hot out 30C the car boosts fine 17psi. When its cold out (nighttime) 10 to 15C the car runs less boost. usually 12 psi ( spring pressure) you would figure it would run more boost when its cold out. So i figured it was the air temperature compensation values for boost. i took a look at the values for duty cycle adjustment and there all set to 0.0. i would think the car would over boost when its cold if there is no compensation. what could it be thats making my car boost less when its cold.
built lsvtec. gt3076 turbo, ram horn mani, s300, 44mm tial wastegate. 12 psi spring. using hondata boost control soliniod and 4 bar map sensor.
also the hondata boost soleniod is very very touchy. im gaining about 2 psi of boost per % of duty cycle. why is it so touchy?
Boost air temperature compensation ?

can i just post my tune or something? i dont have any datalogs but everything is the same but it runs less boost when its cold out?Spunkster wrote:Impossible to say without the calibration and datalogs showing what you are describing.
heres my tune anyways.
