Actually, I was surprised when I installed a 10 lb. flywheel in the 240Z that downshifts *were* easier and quicker vs. with the stock 23 lb. unit. Wasn't expecting that, but there you go. No ECU, just 45mm 3x2 carbs

After some research it appears the ECU is the major source of the problem. Unfortunatly the tuner ran into some problems with the reprogram and I have not driven the car yet this year. I may not make any events this season, in any case I also need to alter pedal height, are there any products available to raise or add spacers to the brake pedal? I made my own spacer for the Hyundai but I would like something a bit more refined for the Mazda.

Try Ken at Protege Garage. or 1-847-736-1635. Many Mazda 3 performance parts may have something.

ECU is back in car, retuned by Dynotronics, big improvement. All calls to PG go to answering service, I will keep trying. Car will not be ready for this season but at least I am headed in the right direction. Thanks to all for advice.
