Weird sudden accel?

[AbeFM]

I've noticed around 3k sometimes I'll get a little buck, I thought just when it was cold, perhaps not seeing the tables smooth, or something.

But here it goes very rich (again, for one data point, who knows what it means at this data rate?) and "accel" turns on, but the RPMs, throttle, and MAP are all pretty much constant. Any idea what's going on?



See the clear PW spike a few points back from the cursor?

Even though tps is pretty much constant, is tps dot?

Pretty much every time that happened to me, i would find even though tps would vary less than 1%, tps dot would be exceeding my threshold.

What type of accel enrichment are you using?

[AbeFM]

Good point! I haven't messed with the accel stuff much, no EAE or any of that.

TSPdot is pretty flat, and dips from -1 to -4 right there (perhaps in response and not the cause of the other spike?).

TPSacc has a spike, it's flat on 100 the whole time, but goes to 102 for that one point....

Has anyone any experience in triggering burst mode? THough there's a number for setting it longer in the ini (more than 1 second) this seems to get ignored.

Or, if I could trigger it to occour when I want, that would help too. Since I seem to have a strange issue with the map suddenly falling off around 5300 rpm, I could perhaps trigger a burst at 4800 rpm?

TPSaccel I believe means that you're accel enrichments are triggering. I guess when they shouldn't be.

Yay! Input.

If anyone knows what would make sense to look at here, let me know. The graph I posted a week back should help?

Your TPS threshold is probably too low. Or MAP if you're using MAPdot at all.
