Ecu Editor works for Suzuki and Yamaha. And you need the extremely expensive Ecu Unleashed shop setup for other bikes, and it also does cars.
"Spark/timing advancers" also know as TRE's, timing retard eliminators, are also usually junk. They perform decent on Kawasakis, but cause gremlins sooner or later on everything. Tricking the ecu into thinking it's in 5th gear all the time is a bad idea for several reasons.
Eliminating the O2's isn't smart without a dyno tune either. Especially since most all FI engines run lean from the factory to pass emmissions.

Just want to remove the Cats as they are a fire risk, and the o2s to stop the lights coming on. My o2 sensors are faulty at present but the truck runs fine, 16MPG US etc Just want to tidy it up.
