Hello and thank you for your awnser, where can i start and stop the Data Logger? I search the forum and the manual and i found nothing.

Is there a extra screen in the screens menue? I have only activate the 3. and 4. user screen. I have push the three buttons long and short. I came in diffrent menues but i dont see a Data Logger screen.

When you cant read my messeges can i write in German. Maby you speak German?

Mit freundlichen Grüßen

Hello, rpm signal from Injector works verry bad. Above 5000 rpm the rpm Jumps from 2000 to 0 and to 6000rpm.
Do you know the best way for the rpm signal. Maby with the vss sensor? I have buy it in your shop. My rpm signal in the dash board and on the Radio comes from can bus. I dont have a extra cable. I have wired the Camshaft Positions sensor but wen i set this to the menue the rpm Shows always 0.

When i make a log the fuel pressure Shows the voltage an not in Bar in your Display it is correct in Bar

Mit freundlichen Grüßen

There are 2 RPM solutions:
1. from injector signal, but only limited injectors are compatible (with clear PWM signal) and RPM will not work with no engine load (e.g. breaking with engine) because injectors are off
2. from hall signal (pulse signal)
I think that you have injectors with no clear PWM signal so you should use only solution 2. Any hall sensors will be fine (VSS sensor connected as RPM sensor will be also compatible). You can also use stock RPM signal - it's usually goes from ECU to instrument cluster. There is dedicated input in UTCOMP for RPM.

Answering for second part of question - fuel pressue as voltage in logs - yes it's correct, you can rescale it in excel e.g. pressure = a * voltage + b, where a and b are your sensors parameters.
