Golf IV 1.8T AGU 150hp
ECU: Bosch ME3.8.3
06A906018CG
0261206518
352127
Please, can someone have a look through my file and say if its any good, and if it's OK for testing on the car? I am looking for about 25-30hp increase.
I just recently found out about this forum. since i have done a few diesels only (my own and some of my friends), but recently one of them bought this GOLF IV 1.8T AGU and wanted me to have a go at it.
I've done a lot of research on ME3.8.3 and 7.5, but still im far from confident in my own skills...
I just want to know if im on the right track and maybe someone can give me some pointer on where to go from here!
PLEASE DONT USE THIS FILE on your ECU's as i can't give you any guarantee that its safe!!!
I hope this thread develops and helps someone like me in the future, because i was having a hard time finding helpful info when looking around.

KFLF - bad (leaned), anyway you don´t need touch this map for stage 1
KFLFLAV - no need to touch this map
KFLDS - very light mod
KFLTWS - you no need
KFZW - can be ok
KFLDTV - can be ok for this boost level
and you need take look on some other maps

Thank you very much for your reply... I will fix those issues. Can you tell me the names of those other maps, because i cant seem to find anything else. |

Ohh... i see what you mean. I understand my mistake now! This is not lambda map, it's injection time, right? Higher values mean more time the injector has to stay open. Again, thank you for making me realise that! |

yes, values in KFLF map are injection times.

It is not injection time. Load is injection time for lambda 1 on this.
It is correction factor for load. If you want lambda-style map, you need to invert it.
Correction factor is X/128. For lambda you do 1/(X/128).

Hmm... interesting. I'll be sure to check it out later this evening. But there is something i read in the S4 Wiki, which states that this map is exactly about the injection time scaling. Note that KFLF's description as "lambda" is a misnomer. It is not lambda at all. It is an injector on time scaling table where larger numbers are longer injector time, smaller numbers are shorter injector time. |

s4wiki is about ME7, this is a completely different ECU.
The only thing that is the same is the map name.
Of course it "scales injection time", but because M3.8.3 has no notion of requested and actual lambda, this map is the primary "fuel" or lambda target map.
In ME7 load is % of filling, a relative value. Whereas in M3.8.3 load is an absolute value - injection time to reach lambda 1...
I could go on, but there is no point. I rewrote the load acquisition algorithm from scratch in M2.3.2 to use speed density and 3.8.3 works exactly the same.
So I have a little bit of insight you might say.

Ok, so first excuse my bad English, but unfortunately its not my first language. Secondly, massive THANK YOU for explaining this map, not just for me, but for many more just like me im sure...!!! but if i understood you correctly, this means that for richer fueling, the values should indeed go down, since this is a "target" map? So for example at the 4000rpm where the value is 1.0, does that mean stoichiometric 14,7...? and for richer mixure its lower as if (14,7x0.9=targeted 13,23)? |

No, as I said, it is inverse.
1/(X/128) = lambda if you want TunerPro formula.
Bigger values = more fuel. It is a scalar/multiplier for load, which is base injection time to reach lambda 1.
So if you have 160 there, you can say it is 1.25x more fuel, or if you invert it, then you get 1/(160/128) = 0.8 lambda.
But remember the values are not "injection times" they are factors for the base injection time.

Now it all makes sense. You explained it perfectly fine in your first reply... sorry for not understanding you there. At the end of the week the car will be here, so i think i will have time to do some road tests then if everything goes fine (fingers crossed). |
