Well after having just the OEM provided tune loaded the last few weeks and very little seat time.... I finally was able to hook up the autotune and build a good map. I added some timing on the low end. I'll have to upload screenshots of the trim tables, target AFRs and my new timing table. I could tell just from test runs the engine was different, anyone that's ever tuned a race engine knows what I mean. It sure as hell is makin some bacon now! I can't find a reasonable dyno in the area that will fit this heavy pig unfortunately, so no HP #'s to back up my claims. Next weekend we head to ride royal blue for a couple days, so I'll build a map for up there. Can't wait for HMF to get off their butt and release an exhaust for this so I can't really tune it up.... About to throw a flowmaster on it and be done with it. So couple of observations...
It likes to be warmed up.... I noticed this with my big red with a PCV. Once you've been riding for a little bit it gets really snappy on the throttle and has more get up and go.
Exhaust gets hotter.... Well I have it closer to stociometric at low to mid RPM to be a fuel sipper, so a toasty exhaust is to be expected.
The OEM tune seemed to surge and would also foul out plugs making for hard starts and would sometimes stall sitting at idle. The autotune can compensate, but once I built the trim table and disconnected it... It seems to be fine at idle now.
The factory O2 sensor is smaller diameter.... Had to drill out and grind off their bung and weld in the larger one for the power commander provided sensor.
No good 12v switched sources in the back... Had to run wires from the fuse panel.
I'll add screenshots tomorrow. Anyone running a PCV that would like a copy of my tune?
