Who makes the 750cc's? Im playing with my tvub on 630cc now, i went to a 4bar so i can handle running e85 eventually.
idle 6.9 partial -7
current values are krkte .0483
1.33
.88
.64
.48
.40
Honestly don't remeber how i got to those tvub numbers, i think i started with what was listed on this thread, then used the excel from another post and thats where im at now.

They are all custom.
You can check if five-o-motorsport have some in stock.

I have found some interesting info about these injectors some time ago -> link. The injector's nozzle is randomly positioned and to make them spray precisely into to the intake ports it needs "indexing" rotating to correct the nozzle position. some other source of spec info -> linkRegards Lobuziak |

Why people spend money on these crap injectors is truly beyond me.

Just as information, these injectors are crap in general.
They are non-linear at low pulsewidths and over time their spray pattern further deteriorates at low loads causing lots of misfires at idle...
The boschdealer specs are wrong as well IIRC.
Prj - You posted Voltage versus Latency values you use for your EV14's. My question though is the values you posted had non-standard Voltage Axis values. Does this mean you altered your 5 Voltage Axis Points to reflect what you posted or did you do some kind of interpolation to use the Stock Voltage Axis? |

No, that means I mostly calibrate 2.2T 5 cylinder engines and the axis is different there :p |

OK, perfect, but--- if you are confident in the values you posted, then I can just change the Axis Points and I bet it'll be fine. Wouldn't you think? OP: I'm just trying to point out that if you can get a good calibration, even with the wrong "axis voltages", it can still work. |

There are many different EV14's. I posted latencies for the commonly available 510cc / 550cc ford motorsport ones. |

@prj: Where are these values you posted? Can't find them.
My calculations are (for EV14):
Volts | 8 - 10 - 12 - 14 - 16
MS | 2.352 - 1.5450 - 1.1211 - 0.8497 - 0.640

My settings are tested on over 10 cars...
But the old 8 bit ECU's are less precise, so there are some rounding errors in there. More so than on ME7.

Are you using these? |

I am using the values I posted at 4 bar, and my target = requested spot on at low pulsewidths. There are very many different EV4's, maybe a good idea to state which injector you are using, as the dead times are different for 550cc and 750cc's etc. |
