stumbling at 4000rpm

[rkhan]

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 ?

[Spunkster]

It might, try what it says in the help file.
