Hello
I was wondering what i need to hook a gm TAC module to a ms3pro. I have a pedal and a tb and a TAC module. I just want to play around with it on the bench.

Thanks

Am interested for science also.

The answer is an interface board that is not released at the present time.

Hello,

I'm currently looking at this functions too and I have some questions :

• External controller send "Pedal position" and "throttle position" to the MS3
• MS3 send "Throttle position target", "RPM" and "Current gear" to an external controller

1. From what I can imagine in regard with tunerStudio, Throttle position target send by MS3 is issue from a lookup table between "Pedal Position" and RPM. So why MS3 send RPM and current gear to the module ?
2. What kind of operation MS3 do with the "throttle position" send by the external controller except than using it in tables and other strategies that use TPS% ? Is there a check ?
3. If CAN bus communication fail, external module may apply a safety strategy (1:1 pedal/throttle response) ?
4. If CAN bus communication fail, how Megasquirt will handle "NO" TPS% ?
5. How IDLE addition operate ? Is Max idle addition is a scaling from IDLE% (0-100%) to "Max IDLE addition" ?
6. In this case, how ALS is taking in account with DBW ? Maybe using ALS as it exist now and setting "Use IDLE Valve" is enough ? But In the case we can't open DBW widely but only at "Max idle addition" position (default 5%) ?

Best regards,
Manu

Hi Manu,

Do you have any news about it?
Did you realize that? In less than a month I have to do the same, but I do not yet know how

Thanks
