It's not easily to found this map. Why do you need it?

I'm guessing he wants to convert a normal car to a Class A Tractor (it's a swedish thing Smiley) that has a maximum allowed speed of 30 km/h.

Possible addr 0x11946, 16 bit, multiplier 0.25
Code in your file very different to others which I saw.

The emission strategy requires the engine to stay at Lambda 1.0 whenever possible.

Thatswhy LAMFA is always 1.0.

KFLBTS is used to protect hardware, but with factors and conditions.
IAT of course, knock, etc. EGT is bad modelled at the early Modells.


Engines die because stupid morons change stuff like exhaust and intercooler and expect ME7 to handle that under any condition. Putting minimum or no money on maintenance or known critical parts along with using cheapest fuel available does the rest.

If engine still not blasted, people with absolutely no knowledge of basic electronics "share" files in the internet and use chinese clones to be "Chiptuners" in their hood Wink

So please don't speculate too much Cheesy

I want to say one more thing. When I assembled my motor from spare parts from a junk yard, me7 was able to adapt and working with software from a different engine model. And there is nothing wrong with chinese clones ...

I began development of free logger for Volvo. https://github.com/prometey1982/VolvoLogger
Work is still in progress but I was able to read ECU memory of my car with 500000 bit CAN network.

This is great news!)

That is bullshit! ME7 and all stock engine control units can not "adapt" to other parts.
It is calibrated to exactly one set of parts.
Different bore, stroke, injectors, exhaust, intake, air cooling is not intended to be adapted.
It has Lambda Adaption to work when sensors get old or minor failures of stock parts.


Because it starts and runs a few days it doesn't mean it will always.


Please read at least something how engine control works before releasing such statements which are fundamentaly wrong.


Have you ever build hardware, tools or software over years of your life and then seeing Chinese sellers getting your reward? Stealing of IP or Work is wrong, as your whole attitude on these things is. Good luck with scrapeyard junk, Chinese tools and lurked Infos on addresses and software :/

2016 - b5204t5, td04l-12t, injectors *831, ecm program - b5204t5 (boost 0.55) - 0-100(8,8)--1/4(16,4).
2017 - b5234t3, td04hl-16t, injectors *831, ecm program - b5204t5 (boost 0.55).
2018 - b5234t3, td04hl-16t, injectors *830, ecm program - b5204t5 (boost 0.55) - 0-100(8,3)--1/4(15,7)--100-150(8,7)--100-200(24,2).
2019 - b5234t3, td04hl-16t, injectors *830, ecm program - b5234t3 (boost 0.85) - 0-100(7,3)--1/4(14,85)--100-150(6,6)--100-200(19,3).

Just not a "few days", but about 1 year.

I am grateful to those people on this forum who spent their time, found, disassembled and posted information in the public domain. I came here to gather information, didn’t say that I understand everything. I just expressed my opinion, but in response I received: no money - do not do it. Didn't expect such a reaction.

Well looks like i've gone and done it...Bricked my ECU. Is it possible to hire one of you young lads to see if its fixable as i was born way before the computer age and know just enough to brick my ecu.
I've read this entire thread and many others to get knowledge and have tried many things from what i've read to fix it but no such luck.
i'm getting IMMO code 321 Initiation signal from ecu missing and ECU code 720A immo signal or something don't remember right off hand again an age thing Smiley
so your gonna ask what i've done so here it is
1-built a bench reading writing unit
2-read all ecu's so i would have orginal files
3-tried to install 2000R ecu data on a 2000xc..didn't work of course
4-write orginal back and now these codes and no start
I know what your thinking but the xc has all the bits and pieces from my R donor car plus extras and i just wanted a starting point...
any help is greatly appreciated thanks in advance....also want to thank all those who have contributed to this thread and this website in the quest for tuning possibilties and perfection.

Did you save the immo data with the 95040 tool on the forum?

Use the tool and flash it back to the ECU, If you saved it correctly it should start the car with your original 2000xc bin on the ecu.
