tips for rev limiter
what does every one run for their rev limiter? Mine is set to 9/10 spark cut, soft cut at 7000, 7200 hard cut.
I've played with mine a little before, but it's kinda tough to mess with something that's only activated at maximum rpms. playing around and setting it to 3000 or so, i noticed that 9/10 sparks cut keeps it from exceeding the limit and sounds like a two step rev limiter (not to mention creates fireballs). I noticed that if you allow more sparks than that, you can whizz right by the set limit if you stay floored. Now, over the past year my car has been megasquirted I haven't given it much thought, but now with the d-rifting season in full spin i find myself hanging around in the 7k rpm range more often. I've noticed that my rev limiter doesn't 'bounce' off the limit like a stock ecu does, it just hangs in the 7k range instead, and while I'm sliding I can't always pay attention to the tach and I don't know if my engine is just revving to the moon or not. I would experiment with it more, but it seems to work, and I also don't want to be jarring my engine too much at it's maximum rpm. |
For a margin of safety, I set my soft at 6800 and hard at 7000. With the SR20 T25, I was well past my power/torque peaks and it didn't make sense to set it higher. With a larger, more efficient turbo running a little less boost, I'd rev it higher if I was still building hp.
Something a lot of people never do homework on when talking about rev-limiters and the track, is their final-drive ratio. Guys with money can build tranny's with different gearsets based on the track... but it's easier to swap in a new final drive in a Miata (not that those accomplish the same thing). Have you looked into a new r&p to help your buttsexxxing? |

I don't understand soft cut rev limiters. I have my hard cut set at 7200 and the soft cut set at 7300 so it never activates. My car makes peak power over 7k, though.

from what I understand it just retards the timing a ton to cut your power so you won't fly right past the hard cut limit.

I'm the same as Savington, disabled the soft limit, and then anhillate the hard when I hit it ;)
Never bounced over my hard limit which is set at 7300 either, settings are spark cut only, 3 out of 5 sparks cut. |
