SRM issues after recalibration for 4.08 gears
 

Had the SRM recalibrated today for my 4.08 final drive and it works great until I hit 70mph at which point the display for what gear I'm in goes blank and I get a warning that Synchro Rev isn't working anymore. Just wondering if anyone has had this issue. Car is a manual 2012 tuned with Ecutek.

This can be fixed with ECUTEK. The tuner calculates the final drive with your tire size to determine what ratio SRM to match per gear. Martin (RS-Enthalpy) fixed mine. Other competent tuners should be able to resolve this pretty easily.

Tuner already did this and it didn't work although he didn't ask me my tire size (275/3519)?

When I ran 4.08's in mine, my tuner recalibrated mine and it worked perfectly

I think either my tuner has done the maths wrong or my FD is not 4.08 but I'm pretty damn sure it is

Well you can start spinning the drive shaft and check how many times the tire rotates.

Just double checked and I definitely have 4.08 final drive.I guess my tuner has to do some investigating
