I plugged the data from the spec sheet into excel. here is the formula for voltage vs. correctin factor @ 4bar. below 10 volts it apears to be linear. so this only aplies above 10 volts. 1.2634 is the correction factor from 2.66 bar to 4 bar. Y= voltage X= correction factor (ms) @4bar Y= -6.596* ln(X)+ 14.012 here are the values i got @ 4bar with 0280158117 from the spec sheet http://www.boschdealer.com/specsheets/0280158117cs.jpg |

I simply changed TVUB based on LTFT for idle, and KRKTE based on on LTFT for partial load. Rinse and repeat. |

So basically, if it was too lean/correction @ idle you adjust the TVUB to give more fuel? |

Yes, TVUB has large influence in short duration injector pulse while the longer the injector stays open the less influence it has % wise. Say 0.8ms TVUB at idle is probably about 50% (assuming 1.6ms per pulse at idle) while 0.8ms at WOT with 15ms pulse is only about 5%. Adjusting TVUB has 10 fold higher influence at idle than at WOT in such situation. |

Correct.... BTW, I did what you suggested nyet and played with TVUB and the idle and cruise is considerably better now. Thanks again! Need to get my wideband in. |

After more research on this, I believe TVUB could be kept stock with the Bosch EV14 series of injectors. Can anyone confirm this?

Hmm. You are using ID1000's, right? I'm using EV14 550cc. So far not having any problems with stock TVUB values, which isn't too shocking because Bosch makes both injectors. I need to figure out how to diagnose whether the injectors need that table changed or not...

IF the car behaves well, no idle fluctuations/stalling, no strange deviations in block 032 and WOT is right on.... leave it as is. |

Yes I'm running ID1000's, with stock TVUB values the car is so lean it almost doesn't run. |

85mm MAF? 4.0 Bar FPR? What KRKTE value are you using and what are your current LTFTs? |

Well with a KRKTE of 0.065 and stock TVUB my long term (partial) throttle LTFTs are -21%.
