Rev limiter finding and removing
When can I find on my e30 323i rev limiter, how can I remove it, because when I press the pedal gas in neutral it goes only in 4000 rpm?!
The rev limiter seems to be in the distributor rotor, that limits rpm by dumping the spark on the base instead to the sparkplugs.
And it does this via a centrifugal weight that cuts/redirects the power to the base of the distributor if it revs to high.
I say "seems to be" because I found some contradicting information if it was in the ECU or the distributor, most ppl seemed to point towards the spring in the distributor rotor however.
I don't have any personal experience with this engine.
But the problem can be many-fold. Just because it doesn't rev higher does not mean that it is the rev limiter. It could be something else, like a worn cam, to rich fuel mixture, worn valve springs, the list can be made long.
