ok i use the 7747 ecm with ostrich and zt-2 wideabnd....my setp mainly runs my motor past 3200 rpms all the time..... but with the 7747 tuning past 3200 using jsut the adder tabel...sucks...is there a way to edit the the .BIN or .XDF to allow for mabey the same ve table thats has a full rpm/map spread.like 7427..and mabey do the same for the SA tabel to? there has to be a way right?

 

hey if you are tuning the 7747, thats the truck ecu right?

Im trying to disable the speed limiter of my dads L19 454 truck, and the xdf file i am using in tunerpro doesnt have an option like it did when tuning my camaro...

what do i need to modify?

we actually dont want to delete it, we just want it to be as high as the tires are rated.

 

not 100% sure as i se ti there is no spee dlimiter in the 7747ecm.....at least that ic an find i use the 7747mine.xdf and ther eis no rev limiter nor a sped limter about what speed is it stoping at?

 

i forgot about this, wow about 85 mph. acts just like my rs camaro did when it hit the limiter.
