Is there a simpler and more affordable version of Rusefi? Hello everyone, I've just started learning about Rusefi, and from what I've seen, UAEFI is already the official minimal version. However, the cost in my country still amounts to over 500 (equivalent to about half a month's wages for an average worker), which is quite expensive for me. So I'm wondering if there are any Rusefi-based projects tailored for beginners that are cheaper and simpler. My goal is to convert a 4-cylinder motorcycle to electronic fuel injection using a mechanical throttle cable. I've looked into Speeduino before, which seems relatively inexpensive, but I'm personally more inclined towards Rusefi. Thanks for any advice!
