Here is a datalog at start-up and idle. I notice that it tends to misfire at startup when it is warm outside. Also if I shut the car off and turn it back on it misfires but runs fine while driving.

I have an 03 RSX type s with JRSC (race version with k-pro), shorty header, high flow cat and greddy exhaust. I recently had 1 step colder spark plugs installed and I have been getting misfire codes in cylinder 2 and 4 as well as random misfires. I also can hear putt sounds coming from the exhaust ...

Thanks for the quick reply! I am going to upgrade, but I was wondering if when you guys return the k-pro, will it have some sort of default setting, or does it need to be tuned immediately? Also, what parameter needs to be adjusted so the idle will not drop to the point of stall.

I have a 03 RSX type S with the following mods: JRSC w-reflash, CAI, DC shorty header, high flow cat and Greddy evo 2 exhaust. I have noticed that when I disengage the clutch, the idle will drop down to about 500 rpm (feel like it is going to stall) then the computer will bump it back up to 900 rpm ...
