RPM goes to 7750, strange problem Options

[Red123]

Hello guys.
About 1 week ago I got some strange problem.
Engine rpm goes to 7750 instead of 7250 and an engine light turns on.
I have AEM FIC 6 installed and Apexi Gen 1 RSM.
Removed AEM FIC and have same problem. Apexi RSM as I know doesn't have remove rev limiter function. personally I don't think that's it's an apexi problem.


What do you think guys?

The check engine problem was solved by replacing a knock sensor.
and on my rpm problem I found this one:

CODE

Standard rev limit is 7400 RPM (The stock rev counter is not that accurate so it's widely reported the rev limit is 7200-7250).
There are 2 places in the standard code that implement the rev limit:

By changing the 94h to a higher value, the rev limit can be increased.  To calculate the value required take the required rev limit and divide it by 50. For example:
7400 / 50 = 94h
7750 / 50 = 9Bh
