Nice numbers...is that a Dynojet? Dzenno and I are planning to hit the dyno this weekend to see what kinda numbers we can achieve with his map on FBO 94 pump gas |

No, it is a dynocom dyno. They read lower than a dynojet but higher than a mustang. It has a feature to "calculate" dynojet numbers and it said 420/475 in dynojet mode. But that's just a calculation lol |

Does this boost and A/F log look normal? The timing curves were all clean. Sorry I didn't get to 7000 RPMs, I ran out of real estate. What does boost normally drop to at Redline?
Also is "Charge Air Temp (F)" the temperature at the throttle body (after the intercooler)? Last edited by MTR; 08-12-2012 at 02:18 PM.. |

Charge Air Temp is measured post FMIC at the TMAP sensor. |

boost spikes probably related to shift. post a log.

After looking at some logs I was wondering if there was an IAT threshold where the motor will begin to pull timing because the air charge is too hot? I'm sure it's just one factor of many but just a rough value like anything over 140 F is bad, etc.
Thanks |

Basically one table establishes the set points(temps) and how much factor it applies(say .3 just for example) and the other table is the amount of timing pulled that is multiplied the factor(say 5 degrees.) So that's .3 x 5 = 1.5 degrees of timing pulled. |

One follow up question. When I collected my logs I clicked the Traction Control button in the car once to disable the traction control, but I didn't hold it down to disable stability control. It looks as if the Actual Boost went above the Requested Boost level and it closed my TPS (TPS act went from 80.9% to 39.4% then back up). Will the car still close the TPS on me if I totally turn off traction control and stability control? Thanks |

One last newb question for the day. I'm trying to understand the interaction between "Timing Cyl #" and "Cyl# Timing Cor". So the DME wants to advance the "Timing Cyl" to 6.75 degrees while under boost but will hold it back for various things such as high CAT. Will the "Cyl Timing Cor" only kick in once the Timing Cyl has been reduced to 0? If my logs have all 0s under Timing Correction, that still doesn't mean that the tune is running well right? I would also need to check the Timing to see if it's advancing to 6.75 degrees? I hope that makes sense. |
