One more EFI question re: rev limit
I've been tuning a map and have it in the ballpark. It's pretty fair for street use, but I'll be taking it to a dyno to tune for MBT and power. Appointment is shortly after Christmas.
While I've been working on it, I've had the rev limiter set at 7800 spark cutout and 7900 fuel cutout. When the map is dialed in I'll make a street version with those limits, but the primary track map will have the limit raised.
So, to get ready for the dyno session, I went out today with the cut outs set at 8500 spark and 8600 fuel. After a good long warmup, I tried to pull the revs up there with a low to moderate load. But at about 78-7900, the tach quickly rolled back to about 2000; I was able to keep it revving just a bit more, perhaps 80-8100, then the limiter hit. And it didn't just bounce off the limit, it basically cut back to idle power...
Is the stock ECU causing the limit? Or is there another EFI constant to set?
Any advice is appreciated.
