Good thread, I have been changing at only 8k, not having had a Honda before I didnt want to push it that far, but with these MF gears it only drops 1k. Using a Spoon ecu & reving higher on track all day would you upgrade any parts or is it ok?
your tach is no relevance to how many rpms your engine is turning. The RPM on the tach is only a signal from the ecu, somtiems weaker and older clusters tend to be off, its not -+500, its a % off.
My stock Ek9 ECU turns to 8600 on the dot, my cluster reads 9000ish
Take it to a dyno to really tell how high its turning.
Ok, so after reading this whole thread.
I now want an accurate reading. What do I need to do?
blinx9900,
can i assume that the actual rpm we need to refer is the one of the dyno chart? if thats the case, from dynochart, my max rpm before cuts off is at 8.5k (where in actual cluster 9k) and the power is still climbing. Thinking to shift the rpm to 9.5k on cluster then and retune.
i think the my actual meter doesnt accurate... my stock year99 b16b stock and original ecu, Vtec activate at 6200rpm in my meter, speed cut at 200kph... sometime i shift at 8200rpm, it drop below the vtec point... so it need few second to rev up again to open vtec again..
Wat the actual vtec engage point for b16b actually?? i heard is 5800rpm.
And the ek9 gearbox ratio is design to stay within the Vtec point rit? when we shift at 8200rpm or above? it shouldnt drop below the vtec point rit?
