The '12, '13 and '15 kx 450f ecu's all have the same part number, 21175, while the '14 ecu is part number 21175A. Can I put a 21175 ecu on a '14 or does the '14 model year ecu require the "A" version of the kx ecu?

Should be interchangable.

When i was doing this on my kx450, i ended up getting a 2010 for my 2009. All of the sensors and injector quantity were the same, so the only difference was the fuel map. Worked like a charm. The part numbers were vastly different too.

Should work just fine.

I have a Vortex ignition available that really wakes it up. If you're interested, shoot me a PM.

I sent you a PM crc245. How do I find PM's sent to me on this site?
