Would a modified ECU from Pettit or M2 eliminate the infamous hesitation problem on the stock FD? Further more, would a 94 or 95 ECU solve the 93 FD hesitiation problem?

After researching and doing all of the recommended fixes I can still induce a hesitation under mild load just under 3k rpm.

Apparenty the actual problem is a bug in the 93 stock ECU causing the primary injectors to momentarily shut off during secondary turn on transition.

 

Hey man just so you know, there is already a thread going on just a couple posts above yours. Post there.

Fuel Pump, 3K

 

I still had 3k hesitation with the M2 stage three though diminished from stock. With the PFC its gone.
