Why is there such a huge difference in everyone's TVUB values?
Nehalem, your values on page 11 are a lot different than the values on page 6?

Here is the spec sheet for the 550's that everyone uses:
FNPW_OFFCOMP multiplier for 60,03 psid is wrong as told in many topics. I wonder what else is wrong in that sheet? I am using "prj" 's values and those seems to be very close if i look VCDS group 032 values. But i'm having huge lambda corrections during acceleration and deceleration. |

the entire reason for this thread is that 550cc spec sheet is wildly incorrect.
it'd be great if someone could get a proper flow bench assessment of those numbers.
that would solve everything if the numbers were correct for the 550's.

Getting accurate (comparable) figures assumes everyone has correct scaling. Assuming anything around here is dangerous.
TVUB on the other hand should be fairly close (at least in the 14v range that they operate at most of the time) with differences accounted for by pressure differences from one person to the next.

You must edit KFBAKL and KFVAKL for these injectors. Try multiplying both by 1.5 as a start, and then fine tune it. |

There are revised sheets from the same source for different ev14 injector which I posted page or two ago.
The TVUB I experimentally arrived at by self-tuning, was only about 0.05ms off from sheet posted there for my 1000cc ev14 injectors so I am fairly certain that the new flow sheets are accurate. As you know, or not, same exact injector but drilled out to flow different volumes changes the TVUB dramatically. You can't use 550cc ev14 TVUB for 1000cc ev14 event though they are the same injector with different spout and orifice. 1000cc will take much longer to open up to its nominal flow.

Here Are the TVUB voltages 7, 10, 12, 14, 18? Not 8, 10, 12, 14, 16?

Yes, redefine your Volt axis in TVUB table if you want to accurately input data or leave it alone and do some Curve Finder or Excel interpolation. |

Anyone have any luck finding a spec sheet for the 750cc@3bar injectors? (im running them at 4bar)

TVUB can easily vary greatly between calibrations depending on how it was tuned. The only constant there should be the difference between cells. Yes, redefine your Volt axis in TVUB table if you want to accurately input data or leave it alone and do some Curve Finder or Excel interpolation.
Adjusting the axis could have inconsistant results as the offset is not linear, but the map lookup is. I could be wrong, but I don't think that cal sheet is for the modified EV14's that everyone is running. IIRC, those are a completely different part number. |

It is for 0280158117 which is what everyone is running. |
