I did the 5 speed swap about 9 months ago then ran the stock automatic ECU for about 7 months. I recently installed a Specialty Z 370cc, single pop, and MT trans chip into a 90-92 MT TT ecu. The car runs great on it but I've always been curios why the slight blip in the throttle when shifting into gear disappeared after installing the manual ECU. The Neutral Switch is wired up correctly and I do get that slight increase in rpm's when going from N to 1st when using the Auto ecu but not the MT ecu.
