Addition inputs from the Microsquirt

[TheSilverBuick]

I just wired up a 4L60e to put behind an L6 with a MS3/3X unit and was wondering if there were any plans to allow the redundant "input" wires to be repurposed?

I would really like to use the MAP and TPS inputs to monitor crankcase and oil pressures. I searched around and didn't see an answer I'd call definitive.

All of the analogue inputs are read and stored in memory, which you can fetch with the correct Megasquirt CAN settings.
e.g. on your MS3, set to collect to CANADCs from:
ID = 7; Table = 7; Offset = 16 For ADC0-3
ID = 7; Table = 7; Offset = 24 For ADC4-7 (EDIT: was 20)

Awesome! Thank you James!

I've hooked up the microsquirt's TPS input up to a pressure transducer but still cannot seem to figure out how to get the pressure to report in Tunerstudio. I do not know which CAN ADC it is, but I've tried the first 7 without luck. What am I missing? Engine rpm, TPS and coolant temperature are communicating to the microsquirt just fine.

I am using the latest microsquirt tranmission beta firmware and MS3/3X with the latest 1.5.2 firmware.






I attached the msq of the engine's megasquirt.

Thanks.

I made a typo in my previous post. From trans.ini

Code: Select all

   adc0             = scalar, U16,   16, "", 1,0
   adc1             = scalar, U16,   18, "", 1,0
   adc2             = scalar, U16,   20, "", 1,0
   adc3             = scalar, U16,   22, "", 1,0
   adc4             = scalar, U16,   24, "", 1,0
   adc5             = scalar, U16,   26, "", 1,0
   adc6             = scalar, U16,   28, "", 1,0
   adc7             = scalar, U16,   30, "", 1,0

So clearly ADC0-3 starts at 16, but ADC4-7 starts at 24, not 20 as I originally posted.
TPS is ADC3 which should translate to CANADC4. (The internal ADC numbers start at zero, but CANADCs are numbered from one to be more normal.)
However, that shouldn't have prevented you from getting the data you wanted??

For the short term I re-wired the sensor to the Megasquirts EXT_MAP input, and while re-doing the gauge to read that input, I think my mistake is in picking the correct input for the actual gauge in TS. In a week or so I'll hook the Microsquirt TPS back up and test it again.

Thank you James!
