I sent my ECM to MFI in Ontario, and it took about 2 weeks from shipping to receive back. I asked Steve to leave my rev limiter at stock since it's harder to detect the tune at the dealership and I don't believe there is any need to raise it since I shift at about 7000 RPM at WOT. (Torque drops off sharply)
You remove the left side plastics to access the ECM. It is fairly easy to remove once you see how it's attached to the bracket. I used a small mirror to check out the bottom of the ECM before I decided to try and remove it. You remove the small plastic Phillips head screw and cut the tie wrap, this allows you enough room to turn the bottom of the ECM towards you and see where the clips are that you need to move so that you can remove the two large multipin connectors. No pictures of this part of the process. Take a picture or two before and after if you want to so that it makes your install easier. The install is the reverse of the removal, after you carefully connect the two multipin connectors and lock them with the tab, reinstall the plastic screw and use a new tie wrap. Done!
The 22 F3S has the air intake positioned on the left side of the Spyder and it is behind the left black plastic circle where you would install additional lighting. The grill allows plenty of cool air that flows past the air intake and over the top of the engine. We had discussed whether or not I should modify the lid of the air box, so I inspected the air intake to the air box and found that it had a 3" diameter round hole that fed air directly across the side of the air filter. With the size of the air intake and its location directly into the air box I decided that modification of the air lid was not necessary. Access to cool air is more important; decent sheltering from rain etc. as well as less air intake noise under acceleration helped me decide. If someone decides that they want more intake area they can cut an additional round hole forward of the stock hole, directly into the air box, and not touch the air cleaner lid at all.
The Spyder started immediately and idled as usual. I didn't notice much change in off idle performance other than a slight surge when cold at low RPM (2000-3000). After approximately 500 miles I ride in Standard mode all the time. I have tried Sport mode and may use it occasionally, but Standard mode gives me the throttle response and performance that I want with fresh 91 Octane fuel.
I installed the Cat delete with 2 baffles that I built to reduce the bark but not the performance previously.
I don't use WOT until I am past 3500 RPM to try and limit clutch slip and rear tire spin off the line. After 3500 to 7000 RPM the power is linear and the upshift is the same as stock. Fuel mileage is relatively unchanged, but I don't monitor fuel mileage. I don't ride like a wild man but at highway speeds the engine pulls much better when passing etc, and seems to rev more freely.
This is the best combination of cat delete and Stage 2 that I have done, and it is definitely worth the cost. This is the last of my performance enhancements for now.
