CA18DET Type 1 board won't rev past 8100

Like the title says I can't rev past 8100. I have the rev limits set to 9000 and the Load limits up but it still cuts out right around 8100. Any ideas?

Limitation of the Nissan ECU is that the max rev limiter is 8000rpm. Increasing the RPM limits beyond these without us modifying the ECU wont will make no difference

is this valid only for ca18det ecu? As for example n15 ecu can rev over 8000rpm...

Most ECUs are limited to 8000 due to coding used

Yes that is correct. However SRs don't particularly like being reved over this much anyway

stock SR's - yes, but I was thinking to build one for 9krpm, and didnt knew about rev limiter...
