My review::
The Factory 14.7 EPA compliant AFR Is very very lean.
This produced white chalky plugs on my stocker.

The X14ieD claims an AFR of 14.0
The XieD claims an AFR of 13.8

I have the X14ieD and my plugs are a nice copper color now.
With This I feel safe adding a Hi flow "Baffled" exhaust and or air filter.

I'm no expert, I just could NOT justify all that money for an ECM and dyno time.
$1,000 for a proper stage one just for a single digit Increase in HP and TQ.
what 6 or 7 at best..No Thanks,

If your Installing a 2 into 1 system or removing the crossover pipe that could Induce
flat spots along the power curve and you may need the adjustablity of the PC V or
some other turner to manipulate the fuel tables and or Ignition.

The X14ieD's I Installed really feels good. the Bike Is smoother at all RPM's
My MPG did NOT drop probably because I'm using less throttle due to the
apparent extra power which Is really just smoother power delivery.
The Biggest change on my 08 EFI 1200R was cold start ups.
Before the X14ieD I'd start It,,
get 1400 rpms,,,then 15 to 20 seconds later a single Miss,,
It would almost Kill the engine,,followed buy 30 to 45 seconds of a unsteady Idle
ranging from 1000 to 1400 RPM's.
A steady 1,000 rpm idle would be reached at about 1.5 minutes or even 2 minutes.
After the X14ieD, Imediatly after,,,WOW
Hit the starter,,,rock stable Idle at 1400 rpm's then 20 to 30 seconds later
(45 seconds on chilly mornings) I'd have me a Tach parked on 1,000 RPM's
The needle looked welded to the Tach Face.

That one nasty Miss was all Gone!

I never noticed a ECM "Learning curve",,there may have been one but I was so
overwhelmed by my new smooth power delivery I still say my ECM figgerd
It had died and gone to Harley heavan XD
