Installed an ACT clutch and Prolite flywheel. After driving about 50 miles, the check engine light, TCS Off and slip light came on and will not go out. I took it to the dealer, they said the ECU does not recognize the new flywheel and is falsely reporting. Has anyone had this problem after an install? Is there an easy fix?

Never had this problem but I know those all come on if you've worn out your brake pads as well

I have the ACT street disc clutch and prolite flywheel and the check engine light didn't come on. Why don't you check it with a OBDII scanner.

Thanks to those of you who responded. Here are the results of testing. I took my Z to the folks at AAM in Gaithersburg, MD. This is what they found.

- PO355 CKP sensor light problem
- C1130 Engine 1 fuel cut system faul-
- Transmission mount bolt (finger loose)
- Bellhousing bolts loose
- Several knicks on flywheel crank trigger wheel, throwing off ignition pattern
- Excess grease found on throwout bearing and all over flywheel
- Lots of clutch dust in bellhousing and flywheel
- Drill marks on pressue plate
- Shifter plate misaligned, 5th and 6th gear alignment off

What a mess . I will never take my car to a NISSAN dealer again for an aftermarket install. I'm gonna do everything possible to get my labor dollars back from the NISSAN dealer.

Many thanks to the guys at Altered Atmosphere, particularly (Frank) for putting my Z back in top operating condition. You guys really made me a believer (customer for life).
