How to go from 12x12 to 16x14?

[Tony C]

it gets worse,
just went round to upload the files again, and now the ecu and laptop will not talk to each other,
wtf is wrong now,
help!!!!!!!!!!!!!!!!!!!11

[Tcal]

I had to reset Vems too at the first attempt..
There´s a something about it:

[Tony C]

just been back to the garage and i could not get mine to reset,
either that or im doing it wrong, which dont surprise me

had enough now, going to wait until a fresh pair of eyes turns up (jago) in next few days to see if he can find out what is wrong.

[antonch]

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.........

That'd be good. I am still trying to figure out how to get VE auto learn to work. I've been meaning to write up a procedure for making a base map.

[Tony C]

sat here thinking about this,
im doing the reset correct with the paper clip, (i hope)
Rob do you disconect the vems from power completly? or just turn ignition off then on to reset?
if just ign on and off im doing that correct,
i think im not getting the second bit right the upload,
maybe im not sending the right data or something, or just getting that part wrong full stop,

at least i know its not an engine fault this time 

[Tony C]

garage is toooooooooooooo cold,
what do i need to reset the ecu and upload indoors?
power and earths to the vems and the serial lead inputs yeah?
as if thats all i can rig up a lead and sit in the warm playing, then

[Tcal]

Hmm, you shouldn´t turn power off after you´ve used that pin.

[rob@vems.co.uk]

Power off, bridge pin 2&3 with wire, power on, wait a second (doesn't make any difference as its effect is instant), remove wire, connect serial cable and follow the proceedure in that thread.  If you power off between it reverts to normal

[Tony C]

it runs ,
but only on 12x12 again but im a happy bunny again,
jago did the same thing i did with the paper clip and the upload, and it did not work for him either, after about 10 attempts doing it different ways it worked. 
Jago got the 16x14 loaded ok and for some reason, the table values would not save,
every time we changed rpm from say 400 to 7000 when we opened  MT again and went into ecu the last 4 or 6 values had changed to 25000 and the kpa had gone from the 5 to 100 we had set to 5 to 256,
any ideas?
the main thing is she is running again on a 12x12 ,

oh it changed all the injector settings to for some reason,

i will get this to run on the 16x14, just any pointers why it has done the above?

thanks for every ones help again.

[miniminor63]

may be a VERY stupid question, but did you upload the firmware for the 16x14 or just the tables?

[rob@vems.co.uk]

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

Perhaps I need to clarify this statement.

Make the 16x14 changes by adding the extra cells to the j[], l[], n[], k[], and r[]  tables.txt NOT using MegaTune to do it.

Once running, MegaTune works fine.

While these values are not what you'd want to run, they should at least set the tables up correctly.

cheers Rob,
will give it a go possibly next weekend.
