I have a 2000 V70r 2.4 auto that needed the motor replacing, I installed a 2006 s60 T5 2.4 engine.
My question is: the newer motor has cvvt on the intake, is there a way to implement it into the earlier ecu mapping or should I just forget about it.
I have a later harness so I could trace the wires and add them to my existing engine loom.

The old ecu is electrically not able to drive the inlet CVVT.
You can forget about it (cost dynamic response).

I`ve a problem with lambda=1 at WOT.
I`ve changed LAMFA but without success.
Any hint what I do wrong?

Thanks for the reply, I know the M4.4 guys use a 555 chip a cap and a couple of resistors to get the CVVT to operate, I wouldn't mind going that route if it will help performance. Or is the intake CVVT for emissions environmental bull$hit. |

Are you sure that this MAP is used? |

I'm not sure is there anybody who intrested to tune Volvo))
Anyway I'm continue my investigations. I've found some more maps inside my BIN (s60r TF80SC).
Also I want to continue dream3R's work with logger and flasher. From my point of view these tools should be free. More general idea is semi-automatic tuning. Bosch ECU has own mathematical model. So we can enter desired values and it's able to calculate all the maps. And add corrections from logs.

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?
