Just curious to know, does anyone else have the same problems i've been having? during the cold *** MN winters when it's 0* or colder, my car runs like totally crap...boggin and throwing fuel CELs all over the place. ever since it's warmed up, my car has been running a lot smoother now and hardly ever bogs anymore. at first i thought it was my fuel filter being clogged from using too much race fuel last year, changed that and still the same results. but then just since last week it's been getting into the 40*'s and now my car runs smoother again. EGT is where it's suppose to be, i get better gas mileage, and my car pulls strong again. could it be that hondata is limiting my ECU's ability to adjust air/fuel as it wishes and is limiting it by only letting it adjust in small incriments around the map that was burned for it during the hot summer heat?

sorry if this sounds pointless...it's time to go to bed now after working 14hrs and coming home to my wife and child and then start working on my car and my buddy's GS-T till just a few hours ago.

 

My car runs the same in extreme cold and warm weather. When it is warm it starts with a low idle for about 30 seconds (which I think can be tuned out, just too rich). But other than that my car has run fine all winter. It might be your tune. I have the s100b. I am not sure what you have. I would doubt if hondata would be the problem though. Has anyone else had this problem?
