Now that my Focus is back to (mostly) stock, I want to start playing around with the Advantage III software to learn more about basic tuning. To that end, I am trying to create a very basic tune that is otherwise stock except for disabling the EGR system and speed limiter.

EGR seems simple enough, just set "EGR Type Switch" to 2. Right?

But disabling the speed limiter seems a bit more involved. From what I can tell, the relevant options are "Speed Limit Off/On" and "Speed Limit Output Shaft Off/On", as well as the "Speed Limit VS Vs Torque" function.

My initial thought is to set both "Speed Limit Off" and "Speed Limit On" to 255, the max value, which seems to indicate that it will never turn on. For "Speed Limit Output Shaft Off" and "Speed Limit Output Shaft On", I set the values to 15000 which is what the Mako software tells me it should be in order to disable the speed limiter. Seems arbitrary, but okay...

Then comes "Speed Limit VS Vs Torque." This seems to be the mapping that determines how to gradually reduce engine torque to create a gentle speed limiter. Again, I follow the Mako software's advice and set all values to 1.0.


Now, my question: is this sufficient to disable the speed limiter? I cannot find any explanation on how all of these options affect each other. For instance, is it necessary to make changes in all of these settings, or would it be sufficient to just set the "Speed Limit Off/On" options? Is the "Speed Limit VS Vs Torque" function still used somewhere/somehow if "Speed Limit Off/On" is set to 255, implying the speed limiter will never activate? And how are the "Speed Limit Off/On" options used differently from the "Speed Limit Output Shaft Off/On" options? Is that only used in some form of traction control setup where the vehicle speed may not correlate to the output shaft speed?


I apologize if these are very basic questions.

The OSS stuff only has to do with the auto trans, same for the TQ stuff.

Just set the Speed limit to 255 and you're GTG.

Alright, thanks! Is there some resource out there that shows what is applicable to what style Focus? e.g. the torque function for the speed limiter does not apply to MTX?

set your speed limit on/off to 255

set your rev limit / speed limit vs tq to all 1`s

leave your speed limit output shaft off / on alone and dont change these

and yes EGR sets to 2 if you want it off

Thanks!

Are there any other "common" tweaks that are done for basic tunes, without messing with the MAF functions and such? I'm starting with the stock Advantage III values...
