MS3 Ultimate - Analog inputs go to 0 periodically

Post by cj.surr »

This is an issue that I've had since initially installing the Ultimate in my car. All Analog inputs will give the correct reading with KOEO, but when the engine is running, they will all flicker to a value of "0.0" simultaneously. I have 6 sensors, and they have different voltage ranges, so when they all have a value of "0.0", that means the ECU is interpreting different voltages for each sensor - this tells me it is not a 5v supply or ground issue. I have tested both 5v and sensor ground at the sensor plug when the issue is occuring and both are consistently good. Some of the sensors share the same 5v as the TPS - which shows no problem. Because of these reasons, I do not seem like a wiring issue - it seems more like something internal to the ECU.

I have attached my tune file and datalog. Firmware 1.5.1.

The datalog has a sensor "lag" of 80%, but the problem still shows with a lag of 15%.

Thanks

You have enabled knock debug data. See the tooltip, this will over-write the sensor values.

Is there a scheduled "fix" for this? We really, really need this in outpc more than wb02 13-16, egt 13-16 and knock 12-16.
