6V -> 3,80 ms
7V -> 2,95 ms
8V -> 2,33 ms
9V -> 1,93 ms
10V -> 1,62 ms
11V -> 1,39 ms
12V -> 1,20 ms
13V -> 1,05 ms
14V -> 0,92 ms
15V -> 0,82 ms
this one is voltage vs ms i tune d from 7 volts to 14 volts i think is ok

next step i ordered a 36-1 trigger wheel with hall sensor from 190-rev.net benz masters shop
wow when the cyl 1 is at TDP where the hall sensor need to be 10 grades from tdc?

It might be, but please include the injector part number and manufacturer for those numbers. Every injector size and type has a different set of latency (dead time) corrections for voltage. ;) Most also include the fuel pressure they were tested at, which will change the corrections.

It can be anywhere, and is adjusted with your Trigger Angle setting. :)
