Xtra ouputs on Pins 16/17?

Post by jesse408 »

If using the Microsquirt CAN TCU for a 4L80E, is it possible to utilize the unused LED outputs on Pin 16 and Pin 17 as extra outputs to switch on a relay based on a conition (map, tps, rpm, etc.)?
This feature would be a very welcome addition to the software.
Thanks.

Once I figure out how to connect to the Microsquirt Trans ECU through the MS2 CAN line, can I somehow enable these pins (16/17) as "remote outputs" through the MS2?

I'm having difficulty communicating with the TCU through the MS2. Can't seem to figure out what these settings need to be for CAN Parameters and CAN Broadcasting/Remote ports, yada yada.
Anyone have a good MS2 CAN config MSQ I can take a look at? The Docs for the TCU were clear and easy to set up, but the MS2 docs are not very specific on how to set up comms with the TCU.

Nothing is needed, so long as you have followed the "Adding trans control to your ECU TunerStudio project" section in the manual.

Check your CAN wires are actually connected inside the MS2 ECU.

Ahh, yes! The Microsquirt is connected through the CAN lines and the MS2 is talking with it just fine. Thank you!
Is it possible to use pin 16 or pin 17 as an extra output for a trans cooler fan/other things?
Can custom channel editor be used to enable that pin perhaps?

Reading through some of the code I can see "shiftup45" which I think relates to the activation of solenoid 5 on pin16 / ALED.
Correct me if I'm wrong, but I did not see a place in the .ini for a user defined output like there is in the MS2 ini.
How can we activate "shiftup45" when (transtemp > 190) and (transtemp < 185) for example?
If anyone can explain how we can do this please let us know.
I just hate for this perfectly good output hardware to go unused and wasted.
