This is the setup for adapting a USB to DB9 Serial cable for TuneECU. I don't know about an OBD connection but I understand the Tre series are not OBD2 compliant, so you will have to be more knowledgable than me to make an OBD connection work.
all vehicles starting from introduction year 2001 had to be compliant with OBD2 by EU laws (see https://en.wikipedia.org/wiki/On-board_diagnostics).
This is an interesting tool, it would be great to hear about your learnings
I would have sworn it was there but couldn't find it now either
Ref HUD ECU Hacker, I have used it on the Benelli BN600, which has two Delphi MT.05 ECUs. The application is far better than my ability to comprehend the information available. This ECU is not OBD2 compliant, so does not communicate with the common OBD2 diagnostic applications. The developer created HUD ECU Hacker so he could diagnose his bike, which had the same Delphi ECU, without using the clunky old Windows application. Was the BN600 sold in Europe? If so, what does that mean for compulsory OBD2 compliance? I looked-up DIRECTIVE 98/69/EC but it is the incomprehensible gobbldygook only lawyers can produce in order to justify their outrageous fees. While it seems to specify emission standards and the use of an OBD system it seems "No use of specific technologies is mandated to meet the standards" (ref Wikipedia) and while it says OBD systems should be standardised it does not appear to specify the standard. So in summary, I am confused! If I find HUD ECU Hacker will communicate with the Walbro/Athena ECUA1, I will be very keen to find if it is capable of reading and writing the whole firmware, as the Help file says it can. I have an ECUA1 here that refuses to respond properly to more than 25% throttle. Carmo Electronis charged $300 to declare it fault free, yet it does not work. The bike works perfectly with a different ECU. If HUD ECU Hacker is capable of reflashing the firmware it might end years of frustration for the owner.
it's wrong definition
but I can't fine any post tell us TX RX use switch protocol....

The Chinese diagram shows the positive and earth opposite to the pinouts for the Sagem ECU shown in Engenia's post. My bike with Walbro ECU has the same Ground and +12V pins as Engenia's diagram - so the Chinese cable configuration is opposite for these two pins. Could they have the pinouts reversed? I have seen that before on diagrams for other bikes. I guess I should have been more rigorous in my checking of the pinouts. I hope there is no ECU damage. That means we are back to some of the Walbro pinouts being a mystery until someone discovers something else. Texa adapter wiring would help, if anyone has access to one for the Walbro/Athena ECU. I wonder now what that Chinese Benelli adapter suits, if the diagram is correct. Certainly not the current crop of Benelli models, which have a different style of 6 pin plug. When the adapter cable I ordered arrives I will check to see if the wiring is opposite that shown in the diagram, which would explain the mystery.
That is the arrangement I use with TuneECU on my TreK with Walbro/Athena ECUA1, the same as the cable offered by Lonelec and functionally the same as the cables by Stingerwolf. The cable I used for years is pictured below. The adapter wiring is as shown in my AUG 12 post above. The Windows version of TuneECU works fine with USB-RS232 cables running CH340, Prolific PL2303 and FTDI FT232RL chips but the Android version only works with the FTDI chips. I now use a Chinese USB-C to RS232 cable: https://www.aliexpress.com/item/33029362074.html? However this does not help with connection to OBD2 applications. If someone knows how to achieve OBD2 connection I am all ears! I have attempted to achieve communication with HUD ECU Hacker but failed on account of having no idea about this sort of wizardry.Does this post from 2008 help?
Benelli TNT 1130 (walbro) Diagnostics!
Hi, Benelli's friends!!! Christmas is not here yet :D , but I want to make a gift to you:hero: Benelli Service >>> CLICK HERE
great to hear
Great.
yesgreat to hear
Do you use the Moto Scan tool from JDiag - Moto Scan - OBD2 Motorcycle Diagnostic Scan Tool - 3.2" Screen ?
Absolutely. The only difference is the Walbro needs the extra 2 pin Superseal connector for programming.
