ECU Question

(1/3) > >>

JC85:
So the previous owner of my '07 Calvin swapped out the ECU for an older one that doesn't support the LAMBDA sensor and has me getting 30-33 mpg on a bike that should be getting 40+. I've been looking for a 15RC ECU, but I have a question that I can't quite seem to find an answer to. It seems like the Calvins had the 15RC.C8, but there were other models that had the 15RC.CC, 15RC.CA, ect. I'm wondering what the difference is. Is it just the mapping, or is it more than that? Will the CA, CC, etc ECUs work for the Calvin if I remap them? Any info would be helpful. Thanks!

Get a Beetle map installed for better mileage, unless you know the maping. OR get it tuned better. My EV gets just under 50.

Wayne Orwig:
Is that dual plugged like the Breva, etc.? That would be a lot different mapping for the spark.
But don't think it is.

I've done that. The older ECU not supporting the 02 sensor just can't get any better than mid 30s.

FWIW: When I was doing more 70mph freeway riding my EVY was getting right at 40mpg. Now that I'm doing less freeway and more city, it's in the mid 30's. Same for my Loops and my HD.
