I don't know if you don't understand me, or I don't understand you.

Anyway, I used smok dataflash to put a 150cc file on a 50cc dashboard, but then if I drive 50kmh, it shows 30kmh on the dashboard instead of 50kmh...

Hi.
I tried writing with vvdi prog, but it destroyed the MCU.
I connected orange wire to pin 5(tool0), and yellow to pin8 (reset). This is correct? (I have VCC/gnd 100% correct).
I tried to program but didn't work. Then try again and no connection and dash is dead.

Do I have to do anything with the security bytes?
I used smok on these clusters, work perfect..

Thnx a lot.

I made 2 last month with vvdi no problem. Strange i dont know what you did wrong. Sec bytes not needed.
