Well it's been a bit now since I have had the AF-XIED on my bike. I leave in 10 days for a multi-week trip on the Terra and look forward to how the bike performs. My bike at the beginning (pre-XIED) 1. Lean Stumble that left me hoping not to be killed at intersections. The bike would either die in the intersection requiring restart or die when I cracked the throttle. Either way it was hella dangerous. 2. Extreme lean pop on deceleration 3. Quirky throttle. Not linear and very snatchy. 4. Idle hunt problems. The ECU was always hunting for optimum idle. It would vary as much ast 250 rpms while it hunted and would sometimes die just sitting in my drive idling. 5. Bike had torque in first and second gear but was not consistent across the power band. 6. I experienced surging at speed. The bike did not always do this but if the day was hot and humid the bike would surge at speeds over 55 mph. 7. With the above problems I found myself not enjoying the ride because I was always worried about the engine stalling at inopportune times. Life after AF_XIED 1. Lean stumble 99% abated. I still get one on cold start if I take off too soon. But it is now a rarity. 2. Lean Pop on deceleration. Gone, non-existent, nada, nothing but exhaust note sweetness. 3. Quirky Throttle. The throttle is now very linear and consistent in all throttle positions. It has a much better feel now. 4. Idle Hunt. The idle is now rock solid at 1550 Rpms. No hunting. 5. Torque consistency. The bike has torque in all gears and it's consistent, meaning that I can find that low end torque in each gear. I can actually wheelie in third gear if I want to (I don't want to, I'm too freakin old). 6. Surge at speed. Gone and the bike performs beautifully at all speeds but the bike really is a pleasure to drive at highway speeds now. 7. The happiness factor. Smiles from ear to ear. I love this bike now that I have it sorted. What's next? Roger asked me to leave the setting at F7 for a 1000 miles or so. I am doing that. However I leave for a trip up the west side of the Mississippi River and back down the east side in 10 days (barring delays). I will be trying the F8 setting after we turn around and head back south. Looking forward to being able to try the new setting. I am still learning FI theory and it's nuances but the threads and articles that I have read have convinced me that short of someone breaking the hex codes to my Magnetti/Marelli ECU that this method is the most consistent means of controlling my bikes erratic electronic and fuel injection behaviors. Would I recommend this device to my best friend? Yes, without hesitation.
