i have a boosted gsr with a pretty good street tune running hondata s300. now that the weather is getting cooler and the air is more dense my car is starting to run rich. i know i shouldnt have to retune my car everytime the weather changes. is there a IAT compensation or something to calibrate or set.
thanks

 

yes
in the smanager
open your bin
go to parameters
click on fuel compensation
it should show -40 to 212 for light medium and high engine load
you can change the correction percentage to bring your a/f ratio back to where you want it

 

oh i assumed that it should correct it on its own. im not up to par on tuning but is this normal to have to make adjustments every change of season?

 

if your tuner didnt adjust the correction tables then they could need slight adjustment...every motor is different so every tune will be different...

 

part of the problem is the tuner is me and my brother, we are learning and succeding but still far from pro.
is there a rule of thumb when make these fuel compensation adjustments

 

Hey I was loking at getting S300 for my CR-X and you stated your tuning it yourself? Just curious, but I want to tune my car myself, is it pretty straight forward from your experiences?

 

your really only going to be a adjusting by a couple percent. i say move by about 2% at a time and without changing anything else, drive the car for a day or two and see if it goes back to the normal ranges.

 

thanks for the help, i will give it a shot
