How to go from 12x12 to 16x14?

[antonch]

I am getting that itch to add more RPM break points. What I have now is not enough for me. How easy would it be to upgrade on 1.0.73?

It should be easy..

1. Download-config.bat
2. Generate-config16X14.bat
3. Upload-firmware16X14.bat
4. Upload-config.bat

I did prepare my 16x14 tables before i did try that and then i just needed to use that Table import function in MT.

It worked fine for me, then i tried to set my tempsensors to 2063 2063 256, then Vems crashed and i had to reset it. I didn´t bother to try again, i just uploaded my 12X12 firmware and working config in. I might try it again today...

I think there is a different tempsensor program for 16x14. Please update if you get it to work. Basically I want more breakpoints around idle region to keep those lambdas spot on. OEM ecus have a 2nd table just for idle.

Yes, i did use that tempsensor_upload16X14 command, i didn´t have enough time today to try it.

I think that those old 2063 hex files are maybe wrong to work with 16X14 firmware, not sure though.

It makes me wonder that why that final 1.0.73zip didn´t include those 2063 hex files, as i´ve understand that they are quite common what people use..
Maybe i did mess something wrong when trying to update to those bigger maps

Stick to getting the firmware updated using the tables and configs, I have concerns about MegaTune tables being imported and exported.

Yeah, I noticed that it doesn't communicate rpm bins values that well even on a same firmware. You end up having to go and change it again once the car is running, weird.

If i remember correctly i didn´t import those tables yet, it was next after that tempsensor upload thing.. Maybe i have enough time today to try it.

Okay, tried again, this time with better luck.
Dunno what went wrong last time.??!!
I did everything as last time.
I didn´t drive it yet but it idled ok.

My rpm bins are:
600, 800,1000,1200,1400,1600,2200,2500,2800,3400,4000,4600,5200,5800,6400,7000
And Map bins go like:
20,30,36,40,46,50,60,70,80,90,100,150,198,240

Good to hear it worked! Now I want to do this but it is my daily driver. So if something doesn't work well--I can't come to work the next day  I mainly want to add idle area. P/T seems to be fairly linear on my engine.

What firmware are you running?

[rob@vems.co.uk]

If youu save your config.txt and tables.txt before you make the change then you can swap back and forth between the different firmware setups quite easily.  Best to try it on a weekend though!

[Tcal]

1.0.73

Prepare your 16x14 maps before you try to update it..
Then you just have to dial them in, no need to think so much.

im hoping to do this over the winter

[Tony C]

i dont know if this is a good idea or not,
BUT:
how about a section on the forum where step by step guides can be posted,
e.g how to convert from 12x12 to 16x14 etc?
just a thought.........

[Tony C]

OOOOOOOps that foooked it,
just did the above, and lost all settings,
none of my settings from the old 12x12 have uploaded, like req fuel etc. why??

[Tony C]

Just checked the config.txt that was dloaded and its empty

thank god i got a copy of the .msq i was running in 12X12 on the PC,

im now section at a time changing the values in the 16x14 file to get me back near where i was 2 hrs ago

makes me wish i left well alone now as the car was running sweet on the 12x12
