i just went on subarureview.com and asked several people thier experiences with various lightned flywheels. this is one response:
"i did get one that translated as misfire on cylinder 1 & 2, but it was only once. when i first got it, i cleared it and it never happened again! I i will say i love it for auto x, and rev matching, but launching is a whole other story....
if you need any other info just let me know!

Subject: act flywheel question
Have you had any issue with your act flywheel? meaning misfire CEL's?
Is this an issue that can be solved with a simple ecu reset? or can this go on a case by case basis?
