Fan VSS shutoff not working on MS3x (JimStim)
I finished building my MS3+MS3x and also got the JimStim v1.5 and JimStimX to work as they should.
TunerStudio is telling me that everything is working fine so far, having a rpm reading on the 99-00 setting, and all the other Variables read fine too.
For testing purposes on the JimStim, i set the VSS input to analogue on ADC13 in order to be able to control it via the JimStimX.
The VSS1 gauge on the cluster is reading fine.
I just tried out a few scenarios that I can think of and found out a few things that are not behaving as I think they should be.
1. In Fan Control, I set TPS shutoff to higher than 90% and VSS shutoff to higher than 60mph.
TPS shutoff is working fine as it is supposed to, but I can not get VSS shutoff to work.
When CLT is above the "Fan On Temperature", the Fan Relay is switching on, but it does not deactivate when VSS is higher than 60mph.
2. Same with A/C compressor shutoff. TPS shutoff working, VSS shutoff not working.
3. In Time-based acceleration, I get a "Tune error" when TPS is deccelerating and Decel Fuel Amount is set to e.g. 70.
When Decel Fuel Amount is set to 90, i dont get the error anymore and TPS decel is working fine.
Can you help me why MS3 is behaving as it is?
