Hi
Any help would be appreciated
I own a Honda Civic Type R EP3 with turbo and Hondata Kpro
When its cold it runs fine
When it warms up and I slowly accelerate to 4000 rpm the the engine stumble almost as a rev limiter (but rev limiter
set to 8000)
above 5000 rpm it is fine again

What is the serial number that is on the K-Pro board inside the ECU?
From Help, About, what is the version of software you are using?
Post your calibration and a datalog showing this issue.

Would this cause the stumble always at 4000 rpm and only when engine warm ?
