That load bearing dyno where you can be very specific with afs at all speeds will really find some more mid range and make your power curve very smooth compared to a wot dyno tune.

I'm a believer in them your tuner did it right

Sure you're not bouncing the limiter? That'll usually shoot a flame.
How can a rev limiter that cuts fuel shoot flames?

Flames are created from the fuel that is not burned that makes it's way through your exhaust and when it gets to the tip, you have fuel + heat + oxygen = Flame... hehe.

Yeah I've tried every trick I've read ... no matter what it still takes about 8 cranks to start. I was told by fltsfshr that this is normal and it seems like from the reading I've done that this is pretty common.

Whether I prime the fuel pump or not, it never turns over in 2-3 cranks like the stock ECU does.
Then, no offense, your tuner is not very good at tuning the start up maps.

It *should* start just like stock but it seems many tuners don't know how to do that which, in turns, gives the ems a bad rep at taking a long time to start.

It also depends on the type of rev limiter.


An Ignition cut rev limiter will shoot flames due to the reason that I've quoted.

A fuel cut rev limiter will not shoot flames (or rarely anyway) as the fuel is cut out, obviously.

Yea, but the rev limiter CUTS fuel, so there can't be any excess to produce flames or fireballs. Where does the excess fuel come from after the fuel cut.
(Basically I'm calling BS on fireballs from a stock ECU due to the rev limiter, because it's quite impossible. )

Exactly. Stock ECU uses fuel cut at rev limit, so there is no excess fuel to make fireballs or flames.
