Well first off you need the TVUB and KRKTE,

TVUB is the battery voltage offset injection time and this can be found on the internet or speak to the injector supplier.
KRKTE can be worked out and if you have a look on here you will find the formula but a good starting point is 34/injector cc so you will start up at around 0.034. You should be at around 0.058 on the 630cc
If you have wideband then you can as you log the trims and see whether it needs adjusting. The ecu can trim +/- 25% before MIL shows.

Temin/Teminva are the minimum injector in time

Fkkvs is the fuel system correction and there is a utility on here that can help you with that

Other than that I would really suggest you have a read of S4 Wiki and get to grips with it first before pissing in the wind. Las thing you want is to do it all wrong and bore wash the cylinders and screw the engine before you've even got going!

BIG Thanks for that answer it simplifyed some things.. I have read the Wiki and also made my readings in forums but i also wanted to achor it here in a thread so i can get help easy in case of missunderstanding the Wiki.. I think the Wiki is good but sometimes i have problems reading it.. I would like it more visual.

I will start off with the tips u gave me and se where I end up.

I made this to understand more visual how things are connected. A formula is a subfunction within the function so to speak. That what I mean.. Sorry if I was a bit nonspecific.

Warning this is only a beta made by a "NOOB" !

good answer! Thanks.. you have been very informative

For example - LAMFAW has no bearing on TABGBTS
KRKTE doesn't affect LAMBTS or LAMFAW
STFTs don't affect open loop fueling.

TVUB is additive, KRKTE is multiplicative.

TEMIN has nothing to do with KRKTE

AFR actual affects NOTHING in your flow except for STFT, which, as I said, doesn't affect open loop fueling.

It is as if you completely ignored the FR entirely.

FKKVS is still on the code path too, you may need it here.

Best think about one module at a time re diagrams.  Remember the FR's for a 1.8 at well S4/R4 different code everywhere lol.

I get this

3.2L
6cyl
1000cc Bosch Ev14

KRKTE = 50.2624*(Liters/Cylinder)/(operating flow rate in cc/min * .684 constant )
KRKTE = 50.2624 * 0.5333 / ( 1000 * .684) = .0391

Could this be plausible?

Also as i understand TEMIN is the minimum time the injector is allowed to be open.. So this mean that if TEMIN is low i limit the openingtime of the injector. And if High i increase time for injector to be open. Is this a limit to not damage the injector to stabilize the idle if very big injectors.

To se if I have to adjust TEMIN my understanding is to log my fueltrims at idle.. IF fueltrim is say 6% off i will have to correct TEMIN untill i get close to "0" at idle.. (But if LTFT is only off scale at idle it could be possible that TVUB is the value to adjust).
