With the arrival of @Elmue Hud ECU Hacker, exploring the ECU has never been easier.

I started poking around the software and seeing what my Z800 has out of the box.
I was able to make a few changes like RPM limiter and Top Speed limiter.

OLDSKULLTuning.com has a tuned file for a few $$$, did anyone try it out? Looks like we can just load it thru Hud Hacker.
A few other companies also have tunes but you need to send them your ECU, which is not ideal at this time for me.

Anyone got their ZForce tuned? Did you notice improvement, responsiveness?

Thanks

If you need informations or solution..is neccesary post photo with ecu and post software. You have interface for read/write this ecu ?

Software was identified in the original post. It can read and write the ECU.

It can be downloaded here: https://netcult.ch/elmue/HUD%20ECU%20Hacker/
As for the required cabled, I am using a J2534 tool, mainly used in the automotive industry. And a homemade cable to interface between the Zforce and the J2534.
Documented here: https://cfmoto-forum.com/800ex800/efi-diagnostic-capabilities-and-obd-compliance/

possible with other tool....exemple bitbox...read/write calculate checksum this ecu...work without problems.

Already have full access to the ECU.
I removed the speed limiters and bumped up the max RPM a bit.
Just no experience with tuning the airflow, the curves, etc.

post original software if you need help with other maps modify ...

How were you able to make changes to the rev limiter and top speed? Any screen shots would be great

You just need to modify the 4 values highlighted in the attached screenshot.

I would like to help. Would need The Bin.file and some serious logs would be nice with 4 logs @ 1 hour.
