So i fit a decat mid pipe with my original exhaust and i really like the sound and the volume is just right too.
After a few days i decided fit a aftermarket ECU just to richen up the system hopefully smoothing out the throttle response and add a bit of extra power.
Having spoken to Austin racing and they said "Yes it’ll definitely be better however I’m unsure if you’ll get the maximum potential using the standard muffler."
Coober says "We have a ECU version for de-cat 790, but never sold one, the power loose is huge. The engine was developed to be used with cat.
If you De-cat the 790 then you need whole setup the get a stable power output."
Now i cant say ive felt any huge loss of power in fact my bum Dyno says the bike is quicker.
Both units look identical with a different logo (and i assume a different mapping?)
So i guess im asking if anyone out there has tried a setup like this or has more knowledge about these things than me.
Do i really need a ECU to protect my engine after a decat?
Im kinda leaning towards the AR unit as it gives me room to move in to a aftermarket slipon at some point if i want to. Also the graph looks more linear.
What do you think?
