Hi all, Just got back from my holidays. I got some info as well. @ Fredrik_a: Would you mind posting your ori and tuned file (or email it to me t5suite@home.nl). I will not share your work but use it for reference / research only of course. I can find the most important maps in ME7 files in the meantime (ignition, requested load, boost control, lambda, enrichment etc). Not everything, but i'm still working on it. Nice result on the dyno btw!!! /G |

I'll try so summarize all changes done to the stock software and send it to you when I'm back from my current business trip.
In general, ME7 is ME7 so if you have a good idea of how the VAG ME7 version work (read a Funktionsrahmen carefully) you will be able to figure out very well how most things are set up for Volvo as well. For a "stage 1" tune there are basically just a few things needed to be done, but working with Volvos there is another challenge (at least it was for me) as there is no VCDS or equivalent software available for Volvo, i.e. logging becomes difficult outside the general parameters available through standard OBD comms where the resolution and number of parameters are really limited.
The logging is of course available using Volvos own software VIDA, but that software including the proper hardware comes at a price (even though you buy a chinese clone) so this will most likely present a challenge for anyone wanting to tune properly beyond the basic stages I guess.
Good luck with the Volvo ME7 work and I'll be glad to help where I can.

Has anyone found anything of interest on the Volvo ME7 damos subject? :-)
The engine is now fitted with new turbo, new rods, new cams, new fuel pump, new fuel injectors and new intercooler. The engine starts up and works quite well after having adjusted the MAF-scaling and a few other things. Back pressure has dramatically gone down on full load from 130% to 80% (relative MAP) so the cam switch wasn't a complete waste. Only penalty is that boost enters about 200 rpm's later compared to stock cams.
The issues so far...
The stock ME7 software combined with the stock cams will never enable fuel injectors before the intake valve is open, no point in squirting fuel on closed valves with no airflow. After having switched the cams, the valves do open earlier and also closes later and as a result... The engine will start to consume air with no fuel added to it for a short period of time creating what I would suspect being a non ideal mixture. This needs to be adressed but I can't seem to find the proper settings for this timing so... If anyone stumbles over a Volvo ME7 Damos... Please let me know :-)
Hi . I am new here. Ithink i have the same engine in my car its xxxxxxt3. 184kW/250HP. Its 2001 V70 t5. Can you plz tell me what are the spec. of material you used i mean which turbo, what fuel injectors, ect. Also if you can tell me which cable should i use to flash the ECU. I have Elm 327 at home, i just ordered Galleto. Do i need KWP2000 also or is any of these two ok? thx for help. LP Borut |

Hi folks, I'm the new guy here  Straight to the topic, I've got 03 S60R with all forged engine, EFR 7670 a/r0.83 and some other goodies. I'm not aiming to self tune the engine, I've got a deal at Rica in Nederland but the problem will be getting there. As obvious, the targeted power is just under 500kW. To keep with the desired power, I'll need to get around the MAP and MAF sensor's limitations and find a way to calibrate new ones in. Do you have a suggestion on some of available sensors and the way of calibrating the new raw data to the ECM. I've got the VIDA/DICE tool and am willing to invest further to get the appropriate equipment for the job. Oh, and I've got the iSoftloader as well. If someone has a suggestion on which tuner would be more apropriate for the job, feel free to say it. Many thanks! S |

I don't remember if the S60R has 83 or 85 mm bore? Have you done anything to the cylinder liners if you run 85 mm? I'm not sure that the liners will appreciate you pushing almost 700 hp's with them as 85 mm bore volvo engines tend to crack in the liners (letting coolant into the combustion chamber) but this is perhaps something you have already concidered? |

Hi, I've got the block re sleeved with Darton MID sleves. The bore is 83mm. It could have been re bored to 83,5mm but I didn't wanted to hassle with that. That should keep up with targeted power with out problems. |

im not sure that there is a specific volvo damos out there, especially for the R model's. so there was quite a bit of a learning curve, have you read through the documentation, and been able to download a copy of your tune, i am willing to help you tune your OWN car, but you must understand the basics

No problem, I'm looking for a suitable read method without lifting chips, will post back |

What is annoying is the lack of a port flasher.
But Stage 1 tune on a S60R/V70R is REALLY easy, because they are calibrated very well from factory, and all you essentially have to do is bump LDRXN, KFZW/KFZW2 and sometimes KFLDHBN as well as adjust the fueling.
I think the hardest part was getting the ECU out, that was annoying.

Did you benchflash? Once I get my head around the ecu I will be coding a obd2 flasher for Volvo ME7
I already have the info needed for my 05 s60r...

No. I did it the old school way. Hot air and a chip programmer  It was a lot quicker than searching for pinouts and connecting pins on the ECU connector. |

i have to say mpps has been pretty painless for me, and you are correct for a good stage 1 prj, it was quite easy in the end, had to play with some boost pid values to smooth everything out, but other then that the basic's
as far as an obd2 flasher, volvo SDA works, but for some reason it keeps timing out on me after erasing, so i have to re-load the ecu through bootmode, i have not tried since then though as i dont really have a huge need?, volvo ecu removal tool and bench flash is fast enough

MPPS only does them in boot mode ...
If I need to tune one properly I'll just put my emulator in.

I take it you were uploading the SBL first with SDA?  I have access to my SBL it's just I'd like to clone a spare ECU to play with rather than risking mine. immo aside, what do you use to bench flash the Volvo ME7? I need to buy something just don't want it to be the wrong thing!! Cheers |
