OK two tunes attached, Standard Territory and my current tune. Probably too many changes to get this to work but I kept changing things until I got it working. If someone wants to point out the minimum changes to get it to stall up then go for it.Originally Posted by JVK
Ignore the high enrichment in the fuel base table as the car needs more LPG up high.

What stall rpm can you get? Mine will stall over 2k then cuts throttle back so stays at 2kgets 2-4psi if iI try in 2nd just cuts throttle and won't stall over 1500. I'll have a look at the maps I'm guessing it's a rpm stall speed issue?

I have tried up to almost 3000 rpm with about 12psi of boost. Have to press really hard on the brakes to stop the car creeping forward. Car launches hard and does a 1.8 second 60ft time (according to my OBD2 app) on road tyres.
I have not tried going above 3000rpm but with over 10psi of boost it is a bit of a waste of time as it smokes tyres rather than launching hard. Would have to put on sticky tyres before going higher and I am not sure the parameters I have set would get me there. Also I am not sure the parameter(s) I need to change is in my strategy yet.
Thanks for that. In summary
Fuel cut Torque Ratio v Requestor Trans Trunc 80 to 0
Spark torque ratio limit v Requestor trans trunc 0.8 to 1.00
ETC torque reduction Trans trunc 0.00 to 6000
ETC clip torque Trans trunc 40 to 1000.
Can you walk us thru it, what do you think did what.
Did you get any trans dtcs? I did when I tried the same numbers.
Turbotrana the first 2 is when you do to remove the torque reductions I know in a manual it makes huge difference to gear changes. I have that on my f6 and it doesn't effect the stall so might be the last 2 that effects it. He also had some different values in the fuel cut off section so might be that too. I noticed when I used same numbers my shifts got a lot harder also.
Anyone got any ideas when I sit idling after a while fuel trims start rising and idle gets real lumpy trims get to +30+40 and idle lumps then trims will got 0 and idles fine again will be like that for 5mims then starts over again.
I've tried new o2 sensors but same issue. Could it be the vct I'm getting dtc cam timing advance out. The vct phaser plugs are broken the clips but have glued them on but still get codes maybe phasers on way out?
And Fuel -> Cutoff -> RPM Limit vs Output shaft RPM
Basically I went after anything that would limit torque or RPM into the transmission. The first couple I seem to remember getting from the VCM beginners guide. The ETC was to max out the RPM and torque that was allowed into the transmission and same with the Output shaft. The last two I put in were the Trans Trunc ones and this allowed me to stall up to about 2900rpm. I have not tried further as I believe there is a 3000rpm limit in a table that needs to be changed and it was unnecessary and I don't have the table in HP Tuners.
Earlier I tried turning off the Torque Module switch and that did not help with the stall but certainly made the gear changes harsher (and quicker).
As I have said I am not sure if this is the minimum requirement but it does work form me on the Territory.
No dtcs for me but my base tune was a CAPA tune so they may have changed some of the parameters. Check the codes and see what has been done in my tune with them.
Guys,
Check out the attached file. I'm on my phone now so won't add a long winded reply but the trq changes I the tune will allow boost on stall (my car makes 10lb on a 12lb tune)

Hiddeous,
Thanks for that, could not see too many differences, the ones I noticed were your "ETC clip torque" is factory and mine is max and the others were in the "Spark tip in Torque control RPM..". Did not check for any DTC's.
And all those extra tables, hopefully Eric will allow the rest of us access to them soon

i did get a trans dtc but then didnt get it again. might have been something else.
i tried with just the
Fuel cut Torque Ratio v Requestor Trans Trunc 80 to 0
Spark torque ratio limit v Requestor trans trunc 0.8 to 1.00
no stall over 2k
Fuel cut Torque Ratio v Requestor Trans Trunc 80 to 0
Spark torque ratio limit v Requestor trans trunc 0.8 to 1.00
ETC torque reduction Trans trunc 0.00 to 6000
ETC clip torque Trans trunc 40 to 1000.
get stall over 2k
i guess its just the etc torque reduction that effects it so you could prob choose what rpm you want with that setting? i might have a try with different settings.
what does turning the torque module switch off do on the zfs? i noticed my changes a bit harder with it off also noticed it used to cut timing(-number at change) between gear changes and now doesnt
also is there any info on what each of the valves affect on the fuel cut torque ratio and the spark torque ratio limit, eg what does the driver demand affect? i noticed Hiddeous you have a lot of them changed
I just adjusted these settings in my tune to try it out, definitely quicker firmer changes but maybe too firm, 2-3 change it will just slip and the rpm will stay around the 5200 mark and the car will only gain speed slowly, also from the log, the throttle drops from 76% (full throttle) to 40% for a short noticeable amount of time on the log, any ideas? It is in the vicinity of 400rkw, so I know the standard box is around it's limits, but it never slipped before these changes.
Edit: it stalled to around 2500 and made 4psi before the handbrake and foot brake couldnt hold it

Ok 3000rpm and 8psi... Instant smoke, nice new addition... But it is still slipping into 3rd, but that's enough for tonight, I'll have to continue troubleshooting over the weekend.
when i had it set up the same at 100ks low throttle overtaking it would thud into gear and back the diff bush happened a few times. went back to stock settings and didnt have any problems. not sure if related will have to do some more testing also
Hey guys,
I made a couple quick adjustments lastnight to try and overcome the sliping into 3rd at WOT. I put the trans hold time to 50ms and adjusted the trans shift in the spark section of torque management back to standard. The car will still stall up to around 2800 on the brake and handbrake, and it didn't slip into 3rd (so I can sleep a little easier), I'll have to go for a good drive to test the higher gears.
Hey guys,
Just hoping to get some clarification around swapping ECUs. Engine conversion im doing is between 2 BAs, but im hoping to use the ECU that went with the driveline out of the stat writeoff due to it having 1000cc injectors. What issues will i face swapping an ECU from another same model car - IE BA mk1 to BA mk1? Is it a matter of taking it to ford to get "reprogrammed" or will i lose features like smartshield permanently? Final question - are there any issues if im swapping a mk1 ba ecu with to traction control into a mk2 car that has switches for it? Is it just a matter of disabling / enabling traction control in vcm suite?
Luke, why wouldn't you suck the tune out of the computer with the 1000cc calibration to look at and make the adjustments in your computer to suit?
I'm still working on the shifts In my tune, I've tried the things that I think could cause the throttle to cut during gear changes, yet none have made a difference. Any ideas on what else I can try? It's not a good feeling, it's the same feeling as when traction comes in
I thought of that but with the complexity of the software and my lack of experience with it thought there was a bit too high of a chance id miss something. The car needs to go to ford to be "reprogrammed" anyway as i changed to a premium icc, and figured if thats all that was needed to accept the new ecu that would be a quick, easy, and less complicated way to get the car up and going.
Luke, educate yourself on the compare function built into the software. It will make it easier to make the correct changes to fuelling.
Where are you located?

Im in brisbane. I guess with no experience with vcm suite i was hoping i could at least get the car up and going with the ecu that matches the engine, then build on it from there. A fair bit of work is going into it so i was hoping to remove variables (in this case within vcm suite as im in-experienced with it for now), and get the car running the least complicated way. If it was just a matter of taking it to ford getting the bcm/car to accept the new ecu then all good. I figured it couldnt be too bad as if a ford ecu fails i would have doubted it took new keys, bcm, abs module to work again.
Have to admit going through vcm suite is somewhat intimidating, as it seems much more complicated and less logical than other ecu software ive used. About to do the high performance academy general efi course to get a refresher asmits been ovdr 10 years now, but would love a vcm suite that specialises in fords or aussie fords if theyre different.
