Better fuel efficiency
- Major gains in acceleration
What do we do to make your KLX run this good?
Fix the ignition timing
We add timing starting at 2200 RPM. We taper it off up to maximum torque. The we retard it a bit until redline. This make the bike much more responsive and also pull harder up to 6000 rpm. The backing of timing from 7500 - 10, 000 rpm, helps with power on top. This is one reason why the ECU reprogram is so much better than just a fuel adding device.
Change the Intake Air Pressure (IAP) Parameters
It clearly states in the service manual, that the IAP is one of the main inputs the ECU uses at lower rpm's, to determine fuel needs. This is something we have access to inside the ECU tables. A nice performance gain was found here.
We optimize fueling
A 13:1 air fuel ratio is what we design for, with or without the 02 sensor being used. If using the 02 sensor, it strives to keep the bike at 13:1 instead of 14.7 :1
