ive used FTL on a few cars with uberdata and crome and it worked just fine. But when i put on my cousins turbo ls hatch it works but it wont let the car rev past 5500-6000, same with my other buddies swapped ls civic. both of them are running obd-2 motors, one with a obd1 wiring harness and the other with a obd-2 harness

 

Are either of them throwing a VSS code (17) or do you know if the speedometer is working properly?

 

both speedos work fine, no CEL. could it be that the vss is obd2?

 

what mph do you have the ftl set to disable ?

 

No it works on my OBD1 converted 2000 Integra.

 

Is this on Uber or Crome?

Remember you need to set the other options higher than your actual rev limit. Like if you forget to set the FTS to higher than your rev limit...you will get whatever that FTS is set at...

 

fts and boost cut will do that if you don't have them set properly. to troubleshoot and fix this:
set fts and boost cut/resumes the same as your fuel cut/resume rpm's and the fts mph to 10mph. see if that works.
