Earlier I have done some ms41 tuning videos. But I often get questions how to tune different BMW ECUs. So in this video I go through many older BMW ECUs on how to tune those, what tools you need etc.

You are a LAGEND Man. Your MS45.0 definitions is the thing that got me into tuning my e60 myself. I was disappointed when I found out that it uses ms45 instead of ms43 I almost just took it to some cheap tuner guy for tune. But because of Your incredible work I get to learn it myself. THANK YOU

You are welcome! The ms45 definitions are still in progress. I hope to get logging definitions there too soon.

@pazi88 9 месяцев назад

It's easy. Just read the full bin and MPC from MS45. Then write those back and check the "Patch EWS" -box before flashing. And that's it.

And also I need to get the definition xdf files for the older chip ecu to use with a new piggyback Bluetooth chip that modernizes the chip style ecus. You now longer have to physically burn a chip with the emulator that cobrartp has come out with and I just want to understand one thing about these files. My question is if the definition was made to work with romraider can I use it in tunerproRT ? Because that’s what then cobra piggy back is made to work with and I was thinking of using ba114 file because that looks like exactly what I’ve been looking for ?

@onesikm3 25 дней назад

Or will there be some problem between the two tuning programs if I use the defintions that were originally intended to be use with romraider ?

Loppu videoiden katselu siihen kun kieli vaihtui. Harmi sinänsä, mukavaa seurattavaa oli aiemmin. Jos ne katselijamäärät ei merkittävästi tuosta nouse niin toivottavasti nähdään paluu kotimaiselle kielelle.

Noo älähän mitään. Just luin uutisista, että kohta RU-vidssa on mahdollista tehdä ääniraidat useammalla kielellä. Kunhan se toteutuu, niin eiköhän nämä tule tehtyä kummallakin kielellä. Toimii varsinkin tämmösissä missä allekirjoittaneen kasvoja ei näy.

Any chance you could help me troubleshoot with it? Really the only thing I want to change is the rev limit.... Appreciate it man.

Not with those tools at least that I did show. Those rely on the ftdi chip on the dongle (that is USB-serial driver). The softwares don't use the simulated COM port, but the ftdi chip directly to communicate with the ECU.

Vähä jäi epäselväksi mikä tää definion file on. Oma säätötausta on ecumasterin vehkeistä.. eli pystyykö vaikka ms42 lataamaan filen, viemään sen romraideriin, muuttamaan karttaa+rajotinta tms. Ja sitten lataamaan takasin? Eka tietty päivittää se ecun firmware? Thäänks, hyvä infopaketti 🤟

Definion file siis kertoo säätöohjelmalle että mistä kartat ja parametrit löytyy kullekkin eculle. Ilman sitä noiden säätö on lähes mahdottomuus. Ja joo kyllä, juurikin noin.
