I have a stock dual mass flywheel and has the regular set up with one missing tooth on the outer edge (circumference) next to the starter ring gear which i understand is for the reference sensor to read and tell the ecu where is the crank position.

With the lightweight flywheel i just got from LA dismantlers, there are no markings so i don't know who makes. it does not have the teeth on the outside of the flywheel and i am wondering if it will work with my stock ecu. It has 3 sections with 3 large gaps. each of the 3 sections takes up about 1/6 of the circumference of the outside of the flywheel and the 3 'spaces' also take up about 1/6 of the outside circumference.
Question is: will this work with my stock ecu?

 

Do you have a pic? That doesn't sound like a 964 RS flywheel.

 

Is one of the sections larger than the other two? If so it sounds more like a turbo flywheel.

 

it has 6 identical sections. 3 raised and 3 lowered. would that mean it's for turbo and doesn't work with c2?

 

no markings on it at all. ie: 964.xxx.xxx no name or anything. got from la dismantler...

 

okay just verified it looks like a 965 flywheel. probably runs on cis vs dme and doesn't use the same crank position sensor? rats!! may have to wait until my distributorless and maf conversion!!

 

Good old L.A. Dismantles...
