So I got the boost by smithflash equipment for my gen 2. I raised the limit to 11.5k and removed gear limiters. Now the bike revs past 11.5k. any ideas?
No rev limit after flash
- Thread starter Quiksilver
- Start date
Whats the point if it doesn’t continue making power past 11.5?

That's why I set it to 11.5k.....
There should be a Fuel Soft Cut, and a Fuel Hard Cut.
The soft cut begins cutting fuel to individual cylinders at around 10,600 ish rpm.
Click the box to turn that off, and the rev limit will increase around 600rpm(low 11k rpm, 11,200, I cannot remember exactly, only that it is not 11.5k, that is too high).
The Fuel Hard Cut IS the rev limiter, and will cut fuel to all cylinders at once at redline.
Leave the Fuel Hard Cut ON.
Do not manually/click arrows to increase the rev limiter beyond turning OFF the Fuel Soft Cut.
There is no more power to be made there on a stock engine, you are just putting a tremendous strain on it at that point.
Great way to throw a piston through the block.

Your tach is reading different then your ecu is what I'm guessing, when frank first flashed mine I noticed the same thing but if your topping out 6th gear it does hit the limiter around 12k or so at least mine did last night

Thanks for the info six. I am in the process of installing a nitrous kit and raised the limiter just in case I flashed the ECU with the wrong values, I didn't want to hit the limiter while spraying. I didn't intend to shift past 11k rpm but I wanted to check and when it went past the 11.5k limit I thought something was wrong. I reflashed the ECU and set the limit to 11.3k and hardcut.

Ya know I didn't think about the tach reading differently than the ECU.Your tach is reading different then your ecu is what I'm guessing, when frank first flashed mine I noticed the same thing but if your topping out 6th gear it does hit the limiter around 12k or so at least mine did last night
Sounds like you went into icbm mode

I didn't think about this
I assumed the tach was spot on. I've flashed a gen 1 a few times but I'm new to the gen 2. I was worried when I seen the rpms over 11.5k and thought I may have botched the flash some how.yep as mentioned above tach reads very fast, if you want it to rev to 11500 indicated, set it to 10900 ish
