i have an 06 comptech(not ct-engineering) charged s2000 and Im having a hesitation issue at partial throttle after the vtec window(4100rpm-4600rpm-ish). the car bucks and jerks horribly. I caught a snap shot on the HDS during the issue but nothing really seemed out of the ordinary on the datalist. Anywho I spoke to ct-engineering about the issue and all they had to say was that the map sensor may have be gunked up from the oil coming out of the charger bearings, but the IM was clean as well as the map sensor. They said it was unlikely to be the ACM(map sensor modifier). If anyone has ever had this issue please respond and any and all input would be greatly appreciated.

My car has 19kmi and the plugs are fine.
Factory 5.5lb pully.

 

i don't know about my06+ since they don't even utilize the same fuel management (fpr), but i know 00-05 had the problem. it scared the crap out of me sometimes, entering a corner at partial throttle with that much hesitation could definitely cause unwanted snap oversteer. but, man does it feel good in full throttle!!!

 

try swapping out the map and another local to see if that solves the problem.

 

thats where it began to really bother me.


swapped map sensor today, same issue remains...I'm begining to think the hondata reflash from comptech is the issue, but I'd love to rule that out too...K pro is just out of the price range right now. F'me right?
