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?!
Second generation (E30) BMW 3 Series and the final 3 Series to sport the boxy '80s styling similar to the E32 7 Series and E34 5 Series.
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.
