Does the Ford pcm allow real time tuning, i read someones comment that said they don't?
Cheers

The whole point of disabling closed loop fueling is to check if your commanded lambda matches the lambda measured in your exhaust. If you leave it enabled it will be blending at lower rpm so it will be transient and your data won't be useful.
So if you are testing open loop only, you could just set all cells to -100, if you just wanted to make open loop occur earlier (eg a permanent change) then you'd only disable it at the rpm and TPS points you desire and most likely leave a blend still there so the transient is smooth.
Ahh, i think i undetstand, thankyou for your help once again

Depends what you want to achieve. Pick the rpm you want to disable it at, and then pick the TPS threshold you want to disable it at...
Ok
I've read that this proceedure is recommended for tuning wideband, do you agree with that?
Cheers

Does it require to change all the cells in the A/D Count column, or just the 320?
Thx

Yes you need to use the IMRC tables as well depending on whether the IMRC runner is open or closed. Turbo has the IMRC removed so it is a bit simpler.
Ok, thanks for clearing that up, I thought it was the other way round
Thx

Hi, just asking if it matters, i see the example car is turbo, are there tables for an n/a engine?
thx

There are several.
Trial and error then?

I was hoping to change the performance mode instead of the manual mode, but I'm not sure which one it is does anyone know?

Yes it still does

If you scroll up to almost the top look for puffwagon post the link is in the post
Excel.file it's called

I'll try and help you out with working through the spreadsheet then as it can be a bit confusing the first time you look at it.
All the yellow cells on the spread sheet are inputs and can be changed, green cells can not be changed.
On the top let hand side you can see it ask for diff ratio, tyre height & Revs/km. Diff ratio should be pretty straight forward to work out and as for the tyre information there are tyre calculators online where you just put in your tyre size eg 285/30/20 and it'll give you revs/km and tyre height.
Once all that is filled out you can move across and there is 3 sets of 3 tables, each table at the top of each column is again yellow which means you can change these figures and the 2 tables below are green which can not be changed. The first column top table is labelled OSS rpm, so you can copy the shift pattern straight out of your tune file and paste it here. Once you've done that you should see shift speed and engine rpm tables change which will show you with that diff ratio, tyre height etc etc and those OSS values it'll shift at this speed and this rpm. For example 1st to 2nd in the below screen shot at 98% TPS with OSS value of 1125 the car will shift at 52km/hr and the engine rpm will be 4691. Be mindful it might not be exactly that but it'll be pretty damn close to that, like I said this will get you in the ball park.
Same principle works for the next two columns. Second column of tables is for shift speed, so say you want the car to change gears at 50km/hr 1st to 2nd at 98%TPS than you put 50 into that cell and it'll change the OSS RPM and engine rpm tables so you know what OSS value you need to put into your shift table on your tune for it to change at that given speed.
Finally the last column of tables is probably the table your looking for as you can input the engine rpm you would like the car to shift at and it'll give you the speed and OSS, put this OSS into your shift pattern table on your tune and it should shift close to the engine rpm you inputted into the top table
Hopefully that helps you out a little bit, after reading it back a few times I'm not sure if it'll confuse you more or help you out.
Hi, now that you've explained it very well i must say, it makes more sense, it's quite clever isn't it?
I can't thankyou enough, you have been very helpfull

There is a excel spreadsheet floating around on hp tuners forum where you can input some information and it'll help you get into the ball park for OSS for x amount of rpm. I'll try and find a link for you. It'll get you close and from there you can adjust it until your happy.
Yes i have found that link and downloaded the file thankyou for offering. I have had a look at it and find i'm a bit more confused lol, but a mobile phone is probably not the best
but i gather i change the oss values as per the chart and in theory the trans should change at those speeds
Thx, Steve

Haven't actually tried myself but I'm assuming if you change the OSS values in the shift table so at 100% throttle it'll change gear at 6300rpm and set your limiter at 6400rpm this will in theory mean you should never "miss" a gear/ hit limiter, whilst still having the ability to manually shift up and down by tapping on the shifter. Just because you're changing the value from 8000 doesn't mean you can no longer change it manually (as far as I'm aware). Just like Darryl said it may be a good little safety net to stop the car from hitting limiter and potentially damage things.
Ok, thanks i understand what your saying. So i would obviously need to log the OSS to understand when it is likely to change. I guess it acts as a limiter or a safety net so as you say it should change by itself if you miss changing manually.

For the racer out there you should look at Shift Pattern 27:
This is the manual shift mode. The 8000 are the output shaft speed that effectively stops the car shifting gear. From this you will see the car will down shift but not up shift gear. So if you want to go to the drags you can alter the 8000s to a speed you want the car to shift. It is not precise so you will have to work on it for your own car.
The aim is to use this table to either get the car to shift automatically at the optimal point or give you a safety net so the car will shift automatically if you don't get your reactions perfect. The advice was originally put up on another forum by CAT600 (Blue Streak Performance who sold Circle D converters for the ZF).
Could you explain something, if i was to change the 8000 value so the car changes what is the point of having the choice of "manual"?

Thanks for the info, it works now
Cheers

Actually in table ZF02798 it wouldn't paste into all cells
I changed cell in the top left corner, highlighted it right clicked chose copy then right clicked paste, it only copied into that cell
is this the right procedure ?
thx

Press and hold the left mouse button to select the cells you want to copy. Or press and hold shift and use the keyboard arrow keys to select multiple cells.
Press Ctrl+C to copy to the clipboard OR right click and press copy.
To paste select the cell where you want the paste to begin. Eg it will paste from left to right and up to down.
This procedure doesn't seem to work, i find that it only pastes to the one cell that is highlighted
I am using ver. 1.11 workshop version

Can you please download the latest version from https://www.pcmtec.com/downloads
The bug with comparing a PCM + TCM to a TCM only file should now be resolved.
Ok Roland, thankyou for your help i shall try with the updated version.

The actual files themselves that cause the crash. Can you send them? Or were you just comparing stock files?
Yes just stock files

Do you mean the strategies?
The F6 and Sprint files are what I used

Hi, I tried to do a compare using the new 1.1 version and got an error, this error log was uploaded automatically apparently.
I uninstalled 1.1 and installed 0.75 version, it didn't even run it just came up with a similar error message. Not sure if this log uploaded
I have been able to use 1.1 before once or twice, but today I used it without internet access, but this shouldn't have mattered ?

Actually, I should mention that the car is an FG XR6, some of the table names don't match up

Fordsrule, yes that might make a difference.?
I would gather information first and see what the Long Term Fuel trims are doing as well as a full power run to see if the commanded lambda from the Base Fuel table is close to what you are expecting. The mods may not be too far away and a simple Speed Density tuning like I outlined here:
Should cover the tune quite well. If you can log LTFT, RPM, Cam Angle and then plot the graph with the same breakpoints as in the tune then you can do a quick fix for the points where the LTFT is > 4% (<0.96 or > 1.04).
Thakyou Sir, I shall get into it asap

same tables as hp tuners?

Hi, I'd like to know if there is a Mass Airflow Table in PcmTec?
I can't even find a MAF channel in the Hptuners scanner, at least none that work
Cheers
