Dear all,
I have found some maps with the help of a member here and I am starting to prepare the tune. Regarding fueling, I have a question:
I will increase the LAMFA table in order to get some more fuel in (in higher boost for example) but I have to increase lambts as well as it is expected that the ECU will get into there after the EGT threshold. The question is, are those two maps blended when lambts is active, or one or the other is being used? Currently they are both 1.000 at WOT. If they are not blended then I will leave lamfa as is and increase fuel (decrease lamda) on LAMBTS so when protection is needed it will get enriched.

LAMBTS is not a map.
Why would you increase LAMFA map?

There are Volvo Maps with KFLBTS all 1.0. But then precontroled via LAMFA not 1.0. But you surely need about a half year more reading before even think of changing a single bit. Just as advice not to destroy your car. If you whish exactly that, then flash tomorrow  |

Sorry I meant KLAFBTS.. In my map it is all 1.0000 at Wot.. At less load it has 3 values less.. I don’t see a reason why you should be ironic.. I didn’t do anything wrong, just asked a question, like forums are about,asking,answering,helping each other..
When I am saying increase lamfa I mean decrease the values to increase fueling.. Lamfa is all 1.000 right now. Why increase fuel you mean? Because if I add more 0.2-0.3-0.4 whatever safe of boost it will be safer.. I would prefer an Afr of 12.5-13:1 at least when using higher level of boost than the engine runs when stock.. I know these engines are designed for 14.7 but when boost increases I would like to enrichen.. I know about tuning, I have tuned several cars using standalones like Motec,Link and Megasquirts, I am just new at Oem bosch tuning..

So prior tuning anything I thought I'd have a look at stock things to make sure there are no problems with the engine so far.
Using VIDA I logged boost, Wastegate DC %, Ignition Advance, MAF, Inj Time ie..
Car has the TD04L-12T turbo (stock 180hp version) and runs about 0.45-0.55bar. MAF I logged maximum from 486-506kg/h. Inj time max around 10ms so this is like 50%DC at 6000rpm (orange injectors) so plenty of room to play. Wastegate DC stays around 45-50% (95% before reaching target, correct).
Do you see anything strange? The turbo has been serviced once before 70000kms so that's why I logged boost etc to make sure it corresponds to OEM data.
Also I read that the 163HP version has the 13T turbo. Is that true? Isn't the 13T larger than the 12T? Strange they put that in the lower hp version..

Hey!
So, I've got a spare ECM from a junkyard. Same PN as my S60R's. I've tried to get it into boot mode according to the ME7 project wikia page, but It just won't go in boot mode. Everything wired up as it shold, the power supply is good, soldered a wire to the 24th pin of the AM chip. Tried to ground pin 24 2-3 secs/ 5 secs/ 10 secs but nothing. Also: vag cable, FT232R chip in it.
Any idea?

Are you trying to read the flash? You need Galletto 1260 tool or MPPSv13 or Ktag etc..

Yes, I'd like to read the flash. So it is not possible with the VAG cable?

I don’t believe there is a program to do it. Buy one of the other tools.

From your post I understand it that you're using Galletto with a standard VAG KKL 409 cable? This should be OK if you've done the hex fix. When I started playing with this I remeber that I initially was using the wrong drivers or something for the cable and it woulnd't work. So that might be your issue. You don't need to ground the pin long, 1s should be plenty, but make sure that it is grounded before you apply power to the ECU. |

Using a VAG171 cable. I did the galetto hex fix. FT_Prog recognises the cable no problem. Interesting is: I power up the ECU and if I put my multimeter on pin 24 the ground is already there. |

Read a few sites back. We have the exact same ECU. Mine came from a 2004 S80 2.0T (B5204t5). You could read the bin in boot mode without any problem? |

Sorry what sites do you mean?
Yeah I read it in boot mode successfully with MPPS v13 and with Galletto. Galletto is 3 times faster though.. I also read the immo using Galletto tool and argdub’s me7gui. If you need any help feel free to ask!
