i had been running a p28 ecu which ran ok on my b16 with the exception of erratic idle (IACV)....i swapped in a b17 gsr computer and now i have an issue when im hitting 4000-5000 rpm...the car loses A LOT of power almost like im hitting the brakes when it gets to these rpms and then after i get past 5 it goes like normal, hits vtec, no cel for anything....and also if i go to 4-5000 rpm and let off the throttle it hangs up like the throttle is stuck open a little but im positive its not b/c my vafc tells me my throttle position is at 0%...anybody had a problem like this? im wondering if its IACV related because when i put this computer in my erratic idle went away...any help is appreciated and thanks in advance!

 

bump...anybody??

swapped the dizzy for my friends and changed the fpr...doesnt do it as often but still will do the power loss deal and it continuously hangs up if you get on it then let off...im probably going to swap out the ecu
