Which experience do you have? I.e. Volvo me7 is very similar to VAG. If you have me7 experience then there will be not very difficult to get Volvo experience. If you have no experience at all then you should read https://s4wiki.com/wiki/Tuning |

But I have few questions, if some of you know. The car is c70 2.3T, gt2871r, 2 sets of bigger injectors, not sure which to use, 465cc or 850cc; stock maf case could be a limit using that turbo?

Defenetly yes if you will try to get all from that turbo. |

Well the big problem would be to linearize for the new maf case...and maybe injectors too, if I will use big ones.

So for bigger injectors is it enough to rescale krkte? and for bigger maf case to rescale mlhfm?

KRKTE and TVUB (and KVB for fuel consumption on dashboard). For MAF yes, MLHFM should be rescaled. |

Yes and tvub too, I forgot to mention it. I want to use electronic boost controller, will this be a problem? The maf housing is 3.5", 60% bigger area than stock. Should I change the map with 60% for the beggining? Or should I use stock maf housing and scale new injectors, and only then rescale maf. I found krkte from s60r, what about tvub, should I change it using percent?

You should set TVUB for your injectors. My OLS file contains TVUB and KRKTE for s60r. Read WIKI more you must know what you do. And you need change one part by the time. If you change injectors then you need change KRKTE and TVUB and logs must contains around zero corrections. When you will finish with injectors you can start with MAF. |

Well my s60r ols file have krkte and tvub too. krkte is the same in both files. Should I take that as good? and copy krkte from that? I think should be fine. Well I read wiki and else, but still have few doubts.

Post your ols file. Volvo s60r has 440cc injectors. If you will install R injectors then you should set KRKTE and TVUB from R ols. Otherwise you need to calculate KRKTE http://nefariousmotorsports.com/forum/index.php/topic,320.msg6774.html#msg6774 and TVUB for your new injectors. |

Continue John's way. I was able to understand how motronic gets data from the maps. And by this approach was able to found more maps inside BIN. But I still didn't understand internal fuel calculations (and how it works at all on low level). Need more time.

Some progress was done. I've found axis of KFMIOP, KFZWOP maps. Also were fixed size and found axis of KFZW maps. This file contains increased boost and KFMIRL map but doesn't contains propertly changed KFMIOP axis. KRKTE and TVUB were checked against 550cc injectors from Subaru STI. Analyzing of BIN in IDA at the very begin. But I found some useful variables like nmot_w, lamsoni_w, rl_w, rlsol_w, miopt_w.
