ND1 Turbo with 3Bar MAP sensor has a limit around 5500rpm

Post by mikarin »

Hi!
I am currently creating data to operate the ND1 1.5L Turbo using the 3BarMAP sensor.

Unfortunately, when the accelerator pedal is 100%, MAP = 1.8bar, Load = 1.8, something like a limiter operates. (Ignition cut?)

I changed the parameters and tables related to Load Limit in Absolute Limit to a value of 2 or higher, but the behavior does not seem to change.

Can someone give me an idea?

The turbo kit is from AVO Turboworld and the blow off valve is from TurboSmart.

The 3Bar MAP sensor is from BOSCH.

Ok, and what tune are you using? Did you change any of the existing tunes, you're using an OTS tune, a custom tune made by somebody else? Can you post it here?
