great thank you very much. I'm proceeding as you advised me. I just need to finish the wiring and then I can start starting the engine. i am using as ecu speeduino NO2c which is the smaller and more compact version of speeduino and is able to manage two injectors. I made a 12-1 flywheel, audi rs COB coil, Bosch water and air temperature sensor. tunerstudio and megalog I have already bought them so even at the software level they are fine. I started doing a tunerstudio project but I would like you to help me set it up. I attach it herektm tune 22_08_2020.zip

I made a few changes, hopefully they will help you get going. You will still have to fill out the VE table. You will still have to enter the TPS and RPM break points and fill out the cell entries. Talk more when you are ready start trying to fire the bike up.

Because you have so many 255 entry's I suspect you did not load the Speeduino Base Tune first when you started your project.
Ignition, a safe place to start is 18 or 20 deg BTDC and as it gets into the higher RPM steadily retard it 4 to 8 degrees. Yes with a two stroke you retard the ignition at high RPM.
Myself I am not using the Speeduino for ignition control, I only use it for fuel injection. I have a different digital DC powered CDI ignition for lighting the fire.
My EFI settings can only be a rough guide. If you had exactly the same bike as me you could follow my settings exactly but as it is, you will have to develop your own settings that suit your bike.

Loading the Tuning Studio Firmware Definition ini file and the Speeduino base tune.
Speeduino Manual:- https://speeduino.com/Speeduino_manual.pdf
Page 11:- Creating a new Project in TunerStudio.
Page 12:- TunerStudeo Firmware Definition File.
Page 15:- Speeduino Base Tune.
Basically.
Step 1:- go to the reference sub directory in the Speeduino folder.
Step 2:- load the Speeduino ini file. (Firmware Definition File for the Tuning Studio software).
Step 3:- Go to the Base Tunes sub folder
Step 4:- and load the Speeduino base tune.
Then you can modify Speeduino base tune to suit your project.

By loading the Speeduino base tune all of the screens are filled out for a four stroke. Easily changed too two stroke settings and you wont overlook some obscure initial setting that might cause you a lot of grief until you discover it.

The KTM 65 SX has the power valve driven open by exhaust gas pulses into a diaphragm. Could this be used as a pseudo map sensor?

I made the whole configuration by putting together your advice and a first configuration that I did. can you give a final check to the project that I am attaching to you and modify or tell me what you don't like?KTM EXC 125 . 2006_2020-08-27_15.59.30.zip
