The reason most of our maps dip there is as someone mentioned in the thread Rafa linked--it's the torque peak and the cylinder pressures are highest. That's where knock is most likely to rear its head. Best to back off a little bit and save the motor. Incidentally, my spark map is *slightly* more aggressive than FM's base map for the hydra. Porting it over was a bitch if anyone cares. Vlad: start a new thread for fuel maps if you wanna see em. This is the timing map thread. Stein: I wish the software had two things: 1) fully configurable breakpoints for RPM and MAP, and 2) a rescale function. sigh. Will go in and adjust the timing more as I go... input like yours is great! Honestly, thanks :) Cheers, M@ |

Paraphrasing, but it's in the manual. |
AFR going to 11 shouldn't make the car buck or sputter.
If you're running closed loop ignition, it may be a too sensitive knock sensor noise map. |

I've been using this map for 3 months now up to ~155kpa on 93 octane.

I did more tuning over the weekend... added more duration by hand to the injectors for my trouble areas. Much better than before but still have a long way to go.

Possible, but doubtful. Your new 600's were 100% tested and should be good. Might check the Windows>ECU data screen when driving. See if all four are firing at the same rate.
Forgot all about this issue; but now it seems to be the problem... Hope I can get it fixed! Cheers, Prospero |

I was a dumbass during the injector install and one took a 2' drop onto concrete... the pindle cap (sp) got knocked pretty good and was visibly out of alignment... I was able to press it back into shape; but it was not 100% spot on. Sadly I was in a bind and had to put my injectors in before it started to rain and so I rolled with it.

Well, send it back to them and if you are up front with them I'd guess a low-to-no cost repair.
