It's important to note that the 990 cannot be tuned using a tail sniffer setup and the stock exhaust. The crossover in the mid-pipe will cause cylinder 1 (left side) to scavenge cylinder 2 (right side), and you will get a false reading of F1 rich and F2 lean. If you attempt to use TuneECU to tune your bike with the stock mid-pipe and a tail sniffer you will end up with the condition seen below...

...What is the best answer - fitting secondary O2 sensors in each pipe?
Second best answer? Making slight mods to the stock map and seat of the pants testing? Pull out the mid pipe after testing each tune to check the pipe coloration. They used to call it a plug chop back in the day when you could get to sparkplugs easier.

What is the pipe sniffer situation when the crossover is removed and a 2 into 1 collector with single muffler used?

Edit: the crossover remains with the 2-1 merge? Also, would having the wide band sensor before the crossover prevent having to swap the sensor from pipe to pipe? Or are the pipe dynamics so different that each cylinder has to be tuned separately?

So, a follow up...

I could fit the ports required and purchase wideband Bosch sensors for $150-200 but cannot see the value in purchasing a datalogger and investing time in learning how to run it for a possible one time use - I can't imagine switching bikes for many years, or wanting to change my tune once I get it smooth and 40+ mpg

I did a test with the LM2 at a dealer.... and the obd2 function didn't work.
No communication so you need to hard wire.

Which maps have you tried? My R mapped bike is smooth and 40+ most of the time. I have the stock 2010 R map not the AKRA map

Stock Map

Catalina38, do you run stock pipes or am ones?
I've got the same bike/year with FMF Q4's and Akra mapping and get around 30 mpg cruising at 80 mph. a little more at slower speeds but i got around 40 mpg with stock map. mechanic said it'll burn the valves with stock map and FMFs. what's your take?

...to get my butt organized to try anything else - that is a good point though I should try it - sounds like several people have put the R map on a standard adventure - my first worry was whether the ABS addition would cause it to brick the ECU, but I guess not...

I could give a crap for the extra horses, but the smoothness would be great!

I prefer to avoid disrupting the exhaust flow as much as possible, so I personally have not installed bungs. Removing the crossover is the option I use. With a 1.5" crossover I believe it's there to prevent a clogged cat converter from over heating...

This bike is able to adjust for altitude so it runs clean and maintains the A/F ratio via the O2 sensors. I ride from -200' to +12000' and it never runs rich but maybe a marginally better flowing muffler will overwhelm the FI? Not likely.
If the ECU could not maintain the A/F ratio it would throw a fault code.
Also FMF states no remap required for their mufflers. I don't have a dyno with A/F ratios to post here but some one else may.
The couple of bikes that I ride with work great with this combo and I'm sure were not the only ones. I'm very comfortable being the test pilot on this one.
Warning this all IMHO, FWIW

25k miles on stock map + FMF's w/ no valve problems. The throttle response is much cleaner with the Akra map and that's what I'm running now.
