Every since i had my MAP ECU tuned, now and again i had a very slight hesitation in first gear (auto). Its something i never got round to getting sorted.
Yesterday i installed a PI3800 and the hesitation problem is worse. If i stomp on the gas from a stand then as soon as i get to around 2750rpm and get to 0.0bar boost the car hesitates a couple of times and then manages to get past the problem area and boost normally.
This only happens in 1st and i have to be on at least 3/4 throttle for it to happen.
Ive searched the board and tried changing the TPS% values on my MAP-ECU but it has not changed anything.
Anyone know what the problem could be?
PHR stage 1
Stock fuel (upgraded pump and reg)
Stock ECU (MAP-ECU piggy)
AVC-R
My wideband reads major lean at the point of power cut. Only for a split second though as the power comes back on quickly.
