Suzuki GSR 750

[Amicuz]

Hi, I've tried everything, but I'm not getting a response from my ECU. I don't know if it's a hardware or software issue. I've downloaded the library and tested it, but I never get a response. I've tested three L9637Ds and haven't received a response. I have a buckdown that regulates the voltage from 12V to 5V for the L9637D logic and an ESP32. Does anyone have any tips on what I should look for? I've been working on this for two months and I'm not making any progress. If anyone want to help i can send code pictures and shematic. Thanks
