Yes, I have binaries of these cars and engines too and know how they look. Just saying there is at least one engine/binary that doesnt have all four same. To know why there are four ignition maps, you'd have to disassemble  You can keep them all the same and be just fine. If you're planning on adding timing, then better figure out how to datalog knock retard... Sadly dissassembly isn't something I know how to do. I wish I did. Contrast - clearly volvo uses KFLBTS for fueling I'm looking for TABGBTS in these files I know it's near to the Component protection fuelling map. Closest I've found would be for a TABGBTS value of Grad C 450... Hex value of 6400. Am I correct? I know these cars have a very low setting. |

It is not near the component protection fuelling map. And it's low indeed. R-models use lowish value whereas LPT engines have it set at zero. |

Ok guys, how about this?:
I'll upload the map defs, in XDF and OLS.
I'll upload screen shots of the maps in 2d Winols view so that noobs can 'see' exactly what they're looking for in their own bin files - so that they can 'recognise' the relevant maps.
If any IDA PRO dissassembly experts, or anyone able to locate additional maps, functions, switches etc could add to this project??
Basically, if we make a community effort to define one file there's a good chance we can locate these other elements generically through pattern matching.
As an example, I located the rev limiters in winols by identifying that they can be found by searching the bin for the 16 bit decimal values "02312 00010 32000 24320 26880"
The latter two numbers, 24320 and 26880 being the limiters with a factor of 0.25.
Equally, I can find KRKTE in these files easily as it's just before the lamfa map and is always near to the decimal values "00004 00091", obviously calculating KRKTE helps to give you an idea of the value you should be trying to find.
By the way, I'm using a factor of 0.00016508 against the theoretical KRKTE value which I calculated through trial and error, which fits the 3 bar bosch injector value perfectly.
I'm rambling, but you get the idea.

Yes, that's because the BTS map is redundant. These models sit at a flat 14.7 stoich regardless. |

They run about 0.85 lambda for R's when pushing it.

Yes, it'd be nice to know where TABGBTS is then I'd love to find CWLAMFAW ; KFLAMKRL and KFLAMKR to implement the Julex fueling method. |

I know nothing about Julex method, but KFLAMKRL and KFLAMKR don't exist in Volvo ME7 iirc. The sequences for finding RPM limiters and KRKTE don't match. There are no such values near either of the mentioned things. So your definition is incorrect. And you can't reverse calclulate and find KRKTE this way. |

It only seems to work with 2005 cars and later. |

I've been holding off buying injectors because of Christmas, but it's either Bosch greens or the VXR ones.
What concerns me is that everyone cites the Bosch VXR 0280-156-280 at 470cc/min but the specs from Bosch give 310g/min n-heptane at 300 kpa. This is the same as the greens. Can someone explain what I'm missing?
I've attached screens from the Bosch automotive catalogue.

but sqrt(4/3) is only 1.155... (assuming you're saying 4 vs 3 bar explains the discrepancy).

You can use the Pink EV6 0280156030 from a Pt Cruiser turbo, I have used them before with good results. 5x 12mm injector spacers and wiring adapters EV6 TO EV1 would be required to do the swap. They are supposed to flow 470cc at 3 bar and 525cc at 4 bar. |

No that's not what I mean... I mean why do people say the VXR injectors flow 470cc at 3bar.  The Bosch catalogue states 310g/min heptane for the 0280156280 which is approx 417cc using a 0.744 specific gravity for gasoline. That's the same as the Bosch greens. The VXR ones have a 14.5 ohm resistance compared the greens's 12 if that's relevant. So why does the interweb say these flow 470 and not Bosch... Confused. |
