CAN Settings with MS3 (PC control CAN)

[tobmag]

Hi Lance.

So I have now the my GPIO connected over CAN to my MS3 with the MS3X card, everything seems to work with the CAN connection.

One thing I need to get confirmed that it is correct,(I have no stim to the MS3 so testing is not that scientifically)
PC stays on 100% independatntly of the load, tested both TPS and MAP (hooked up tps to the trans stim) Load does change in TS so CAN is working
PC% does blip to 70% while shifting as it should.

Is PC sitting on 100% due to the missing engine rpm input?

While I had the GPIO as "stand alone" PC was following load as it should.

Is PC sitting on 100% due to the missing engine rpm input?

Tobmag,

Either missing RPM or missing load can do this. The PC is set to 100% if the engine isn't running because this reduces the current draw (PWM=100% is minimum current draw because the PC solenoid is a 'bleed' valve) and eliminates some PWM noise. Of course, if the engine isn't running, the trans doesn't need the line pressure reduced (or to do much of anything else, of course).

Hi Lance.

Thanks for the clarification. I knew there was a logical explanation for this.....

Hi Lance.

Here is my MSQ from the mS3 set up. I'm using the latest MS3 code avalible; 1.2.0

You need to do the following changes in the CAN configuration under "Tools" and change ;
MS-II in2ram block to 7
MS-II variable offset to 630

There is a question mark for the above since these values are locked in the .ini

According to MS3 manual;
On MS3 Advanced2->Speed/Gear sensors set gear to CAN and
CAN ID 1, Table 7, Offset 12
VSS - unknown

Should be On MS3 > Advanced Engine >Speed and gear sensors

Make the settings as on attached pic.

Then on MS3 go to CAN/Testing > CAN VSS, gear, EGO
Add data as on attached.[attachment=0]CAN VSS, gear, EGO.JPG

And here is the MSQ I was using.

Tobmag,

Thanks for posting this, it is sure to be helpful to many other users! I will add the info to the manual as well.
