I dont know if this will sort your problem, but this works for my car. I belive you got some other issues. Send a log or your file if you want.
TVUB @ 4bar
7.04 2.800
10.07 1.800
12.04 1.299
14.08 1.000
17.88 0.699
What are your KRKTE TEMIN TEMINVA |

Krkte is 0.0445... This is as said E85
The rest does not matter. It is not your problem.

I swapped the base file and ran your TVUB (as above) with KRKTE 0.029193 TEMIN 0.2187 TEMINVA 2.18 Just driven 200km - absolutely fantastic - trims within 1% No misfires at idle and absolutely smooth. The Bosch spec sheet was certainly a long way out. Thanks to Nye and Daz and an extra thanks to Mocke as your numbers are spot on. |

Cheers mate.
The values I posted are right from the latency sheet I got from deatschwerks. I had two injectors done, but were identical. Interesting that yours and his were so far off. |

Agreed.
What was also weird is that once I swapped the map I was getting 12% rich on my numbers and 7% lean on yours. Mockes were between the two so I went with them. Had I not I'd still be looking to KRKTE to try and solve it.

In general, use krkte to adjust partial trims, tvub to adjust idle trims.

Mine injectors came with the spec that was way off as well. Was really wrong on two cars i have seen.
Numbers i got that work was done by trial an error.

Well, Yes, but I am saying I bought injectors, and had them tested myself. These were observed latencies, not just spec sheet numbers. That's why I find it odd. I'm thinking compounded error, but who knows. Good work! |

In general, use krkte to adjust partial trims, tvub to adjust idle trims.
The variations of -12 an +7 I mentioned were partial trims and I would normally have kept adjusting KRKTE and TEMIN, which I was doing, with no result. In this instance TVUB was the primary problem. |
