Are you saying you have camshafts installed from the company Comp Cams?

Focus's have ME7?

Your camshafts must have big overlap. You should advance ignition and raise idle engine speed so the trims would be normal. IMHO such cams are not any good when used with stock engine management based using MAF sensor.

Advance ignition on all map ?
You think 1° will be good ?

Not at all maps for sure!
You need more advance at idle and low load/low engine speed and less advance at high load/high engine speed.
For example I had to bump ignition advance like 6-7* (to 15* BTDC) to make it idle.

Oh, okay ! Thank you !
With good ignition and good tune on TVUB and KFKHFM I think i will have a good idle
And for Partiel load I will use KRKTE !

IMHO you are still wrong.
KRKTE, TVUB and KFKHFM are not the maps which one should tune to alter fuelling. You need to touch them only if injectors or MAF sensor are replaced with different parts.

There are proper maps to tune your fuelling...

So you will have big issues to dial in everything at once if you do not have data for such injectors and MAF correctly dialed in...

Unfortunately it is not that easy. That way you will get data which is not perfectly precise but still better then taking random numbers. That is why I am always suggesting to dial only one part at time. Running wilder cams will make dialing them even harder.
