PCMTEC Power By Gear MT-82

[stang17]

Just reaching out to see if anyone with a MT82 and PCMTEC has experimented with the power by gear tuning. I've been testing various power limits in the following tables.

MT Max Torque Gear 1
MT Max Torque Gear 2
MT Max Torque Gear 3

With 3.55 rear gear and a 275/40/19 All season tire, 250 ft lbs in 1st, 300 ft lbs in 2nd, and 400 ft lbs in 3rd gear seems to be working rather well.

On the street I drive with TC turned on, and notice TC barely enages anymore and car accelerates much smoother.

Would love to be able to incorporate this with Custom OS to make multiple tunes slots for varying track/street conditions, but unfortunately these tables are not available in Custom OS at this time per PCMTEC.

Has anyone else tried alternative ways for use with Custom OS?

I’ll have to take a look and see how I did it on my 10R80. I have no idea if the tables I used are available for Custom OS. It’s been a while since I’ve messed with it.

I used the following tables to do it, I have no idea if these exist in a gen 2 manual (or auto for that matter) car, but I did confirm they are all available in Custom OS.

63135, 63136, 63137, 63150, 63151, 63152

Hopefully this helps. I can pull a manual gen 2 file later and take a look, but there's no telling if they'll work even if they are in there.

I just pulled a gen 2 manual file and I see similar tables, but since I don't have a gen 2 manual file licensed I can't check to see if they exist in Custom OS.

63145, 63148, 63157, 63130, 63133, 63159

I had to do more work than just make changes to those tables. One of the biggest ones was setting WOT pedal start and end (28212 and 28213) so it works like an Ecoboost and controls the TB at WOT through driver demand torque. This required, initially in my case, hacking up my driver demand table to make it so it would request enough torque to actually open the TB 100% at WOT when torque wasn't being limited by one of those tables.

There was more I had to do in order to get it all to work, I will have to pull up my notes later to see how I got it all to work, but the TB and driver demand torque was the biggest hurdle once I got it working.

This is one if you hit up our support we will always get back to you asap. However as you asked here I'll reply here.

These have a different name in the 15-17 and are named incorrectly. This is likely your issue. The table auFs are

auF63130 Gear 2 A
auF63133 Gear 3 A
auF63159 Gear B

I believe these are the same as low high med in the screenshots above. I will arrange to have them renamed so you can find them more easily.

As said at WOT the throttle goes wide open regardless however, so you will need to tune the car like an ecoboost with correctly defined torque tables as meJohn described for them to work at a pedal position greater than is defined in WOT=WOP

auF22997 Throttle Blend - WOP to WOT (80% by default in most 5.0s)

auF63130 Gear 2 A
auF63133 Gear 3 A
auF63159 Gear B

This is the part that confuses me. How do these 3 fields correlate to a manual transmission. Is gear 2 A "2nd gear in MT82" and gear 3 A "3rd gear in MT82". What gear does gear B correlate to? 1st gear?

It is high low medium like in the ecoboost. How the different "loads" are defined I'm not sure but I could find out for you if you post on our forums so it is documented in one place. The ecoboost tuners will be all over this.

If you post the forum link here I'll do my best to get back to you.

edit: I don't know why Ford did it this way but the table used is selected via the following table
auF74454 I believe this is all simulink auto generated code as it doesn't look human written.

It takes "engine type" and then decides which table to use. In a 5.0 its all 1, so it will use table.

1 will use auF63159 Low / Gear B
2 will use auF63130 Gear 2 A / Medium
3 will use auF63133 Gear 3 A / High

I struggled getting above the 748ftlb limit on the DD tables once Wot was requested with throttle settings similar to the Ecoboost. Tq limited via tb just fine but would no longer request enough tq to open it 100%.

I was going to hack the tq tables a bit but figured I was missing other settings.

Are your tq tables stock and extrapolated out or whipples? Think Whipple uses engine type 1 where as stock/frpp/roush with manual use engine type 0
