Only 1 hating on it! The MS3 I have set up can do more than most flashed/ROM ECU's can do.

I can go from running a 2 cylinder motorcycle to a fully sequential V12 with COP and 2 stage fuel injection. All with the same MS3 engine management unit. Would love to see an OEM re-flash do that.

Not to mention it can use Speed density, MAF, Alpha-N or a combination of all 3 tuning maps. as long as the necessary hardware is there.

The more I read about the SCT Tuner / ROM flashing it's getting further and further from matching the capabilities of the MS3.

When I said here, I meant on the whole forum. And youre right, it seems to be coming from a small group of people.

Don't forget about %Baro fueling. I run that because of all the altitude changes I see on a daily basis.

Haven't been around the forum long enough to see that. I just know that I can't use SCT for my ECC-V ECU and that seems to be the pushed tuning resource here. So I guess I'll never know just how great it is. I'm not going out to buy another ECU when I have a fully capable stand alone EMS sitting right beside me.

Yeah I did miss that one. I'm coming over from the Honda scene where speed density with Baro corrections is standard!

Not hating , why add a standalone and remove a more powerful processor with all the calibrating done , yes ms has a knock circuit board but you have to find and set the frequency , threshold done properly this process alone will take longer then tuning an engine fully , you have to make it knock to adjust and this isnt a one step process you have to learn what to set it at and it knocks many times in the process and this is just one headache that has to be done thats already done with the stock Ford ECU

If this wasnt a car that the ECU had very good software in Diablosport and SCT then I would say go standalone , I wouldnt pick ms but thats a personal preference

So you can do TQ limitation by gear/RPM/Load?
You can do EVAP management?
You can do progressive fuel pressure control?

Unless you've really played with the Ford ECU, I really don't think you know what's capable.


Far as MAP only. There is a switch and input for MAP. I've never tried it to see if it works on a Focus or not though.
... and it's very easy to strip the IAT from the MAFS; they are 2 separate circuits already.

There is a lot of things the ms cannot do but most that have it have not tried tuning the Ford ECU so will never now how much easier and safer it would be

As for the MAP iminhell I have been tuning a good bit of EURO Foci and there MAP , only real thing I see changed in the SCT software is the MAF to MAP switch then a "speed density" section with the proper things in there to adjust the fueling , the EURO Foci seems to be a lot of them MAP and it was an interesting change from the MAF tuning

Sure could , SCT also offers the software where you could do your own tuning

TQ limitation by Gear. - Kinda, Boost by gear. However this is an example that further strengthens my argument, as my factory ECU never supported Torque Limitation.
EVAP Control - Yes
Fuel pressure control - Yes, and currently running it

I have played with the Ford ECU using TwEECer. I ran into hardware limitations. Could not do Launch Control or Flatshift. Could not do Sequential Spark. Was forced to be stuck with a recirculating dump valve instead of Open BOV and still maintain any sense of drivability. Could not do Traction Control. Could not do IMRC Control for the DSIM. Could not get it to read an Ethanol Sensor.

I could keep going....
