Ms3pro to pcs tcm-2800 via canbus?

Post by Motoren »

Hi, I use a PCS TCM-2800 to control my supra auto transmission.

I was wondering if it was possible to share sensor data with the ms3pro ultimate via canbus?

The TCU needs TPS, engine temp, map, and I would like to grab the VSS and gear oil temp from the TCU.

Best regards
Kent

You'll need to find out whether your transmission controller can use custom CAN addresses and data formats and adjust them to match what the MS3 sends in the "Dash Broadcast" format.

I wasn't able to get the TCM-2800 to work on the A340E transmission :( so i have bought the micro squirt to control the supra a340e transmission, but haven't installed it yet.

so I have a spare TCM-2800 with universal harness for sale if someone needs one :D

I have a successful A340E control over GPIO with Megashift.
If you are going Microsquirt use James' Microshift and consider
using a PWM output from your MS3pro Ultimate to use the
"backfill accumulator" solenoid on the transmission or you
may have some harsh light load shifts. Unlike the GM transmissions
backfill accumulator on the A340E is important to use.

Hopefully we can get James to add this table in Microshift
however I think we are missing a PWM output in the
Microsquirt for this. (Maybe I'm wrong)

Mine worked without it but part throttle shifts were
hard to get right.

Yeah i have already talked to Matt from Diyautotune about the accumulator pressure. And I have a spare highside output on the 4 highside output unit I bought from them.

Any of you know how I can get the microsquirt to function with my tiptronic shift ? I ground the main one. Then I get a ground signal on the separate wires, EI when I move the shifter into manual mode and the same when I move the shifter up and down. On the tcm-2000 I have used before I just had to wire them into the input of the TCU and select toggle. But it’s not like that in the microsquirt as I can see.
