generic sensor based rev limiter
Hey guys,
I've already posted this question in another forum, but apart from asking "why" I didn't get any answers.
Is there any possibility to use a generic sensor for changing the rev limiter?
e.g. I use an oil temp sensor in my ECU and I want to limit the max revs when the oil is <70°C AND >120°C (for fail safe).
The revlimiter could use the coolant sensor as reference, but not any generic sensor.
To answer the question "why" directly.
A) I use a dash 2 CAN, but at the moment I can't figure out how I get the generic sensor shown in the dash, so I've got no gauge for my oil temp at the moment.
B) I think it's a safe way to restrict if the car is not driven by myself.

At the moment its not possible. The MS3 code doesn't support this. You may be able to get around this by declaring that the input for the temperature is also an input for oil pressure, then setup min and max "oil pressure" values per RPM, but these values will be the oil temperature that you want.
The drawback of this method is that if you already have oil pressure safety enabled, you can't do it.
Method 2 is to setup a loop for the oil temp range you want, and use that as an input for the "pit lane limiter", which you can use to setup a max VSS (sadly you can't setup a max RPM as this is really meant to limit vehicle speed not RPM).

Plan was not to disturb you again haha.
Ok, I see, not possible for me.
Both (Oil Pressure and Pit limiter) is allready in use for my ECU.
So there is just the possibility to get the values to the dash and give out a warning alert.
Thank you very much!
