GL1800 (2012+): Guhl Reflash 2.0

[Cruiseman]

I just got off the phone with Don Guhl and he is getting ready to apply the latest reflash to my ECU. I had the Level 3.1 reflash done about 6 weeks ago and was still encountering a significant cold engine stumble in the 2,600-2,800 RPM range. He said they have modified the fuel mapping significantly to add more fuel in the lower rpm range. I should my ECU back by Friday, so am I anxious to see if this resolved the stumble once and for all.

My ECM comes back tomorrow as well. I originally had the 2.0 flash and developed the 2000-2500 rpm, 1/4 warm flat spot as well.
Hoping this "Level 4" flash fixes that.

I have been patiently waiting for this issue to get sorted out. Once stable I'm ready to pull the trigger on an ECU flash.

Me to. Patiently waiting for the reports from those who have the latest update.

I got the ECU back today and hope to do a test ride here in about an hour. Fingers crossed. However, the last time I had the reflash, the stumble left the building, but returned a couple of weeks later. Weird.

That is odd. It kind of makes you think there is something other that the ECU causing the stumble. Maybe a sensor out of range.

I am very interested in your findings. Thanks Cruise

Only a short preliminary ride. Too soon to tell. I think I want to test it for a week before I post any results. The last time I had the reflash, I shot of my mouth about how it got rid of the stumble, then within a week, the stumble returned. I want to take a more measured approach this time.

It's been a week... any news god or bad?

[Cruiseman]

Watch for my report coming Friday!

Gulp! That's at least 5 days away? :p
