dismantle the dizzy to get at a little metal disk there should be 4 large slits/gaps in the disc and a little one. you join the little one to one of the bigger ones by removing a little bit of the metal with a stanely blade to make one big one if you get me this raises the limmiter......
or as i did you can place a bit of sparkys tape over the little gap/slit to remove the limmiter all together dont know what it reves to as my tacho needle was off the clock and then got valve bounce :doh:
Anychance someone could pop a picture of this up please?? Might have a crack at it myself as well :grinning:
So is this actually worth doing? I run a 1 litre with 1.3 cams, always been tempted to do this as I think the limiter cuts in way to early (about 6300RPM). The engine is still climbing in power and I reckon the peak is about 7200RPM, easily. Would you reccomend cutting across the hole, or covering up the smaller hole? Does it run noticeably worse?
Yes, it cuts at 7300rpm on high gear, because you are at high rpm for too long and the ecu cuts... Yesterday i got a fuel cut on my SR, hill climb on 3rd gear @ 150kmh.
Just remember that this does have additiional issues. That 5th slit allows the ECU to run fuelling sequentially. With out it the ECU cannot get a 720deg lock, instead it will run batched fired. This doesn't normally seem to be an issue but just thought I would let you know.
At some point ill put a K11 on a dyno and see if running the car with the slit covered changes anything...
Is it like a safety precaution? Should you be revving it in high rpm for too long It cuts out?
So it's not like you can rev it in neutral to 7300 and it will instantly cut out?
Interesting you say that, when i had that mod, my 1.0 feeled more powerful then with stock dizzy and the ECU set to 8.000rpm. I was told that batch fire give more power, but only at high revs, is this correct? In any way the Micra ECU uses batch fire at a certain rpm?
Never had problems with high revving my engines, the 1.0 (205.000km) does 8.000rpm and the 1.3 (129.000km) does 7.300rpm. In neutral you can rev it and doesnt cut...
Maybe some sort of safety precaution then? If you rev it in neutral and it doesn't cut then maybe it will only cut when held there for a period of time or under load.. Who knows?
Do you think that if you decrease the gap between the two slits that the limiter will increase respectively?
I blocked of the small hole in the disc and all it would do is tick over but would not revSo is this actually worth doing?
