i just bought my bike used last weekend and have been riding instead of tinkering with the bike. decided to remove the seats/cowls/etc. so give the bike a detailed cleaning and i find this under the seat.
i had to pay a few hundred bucks for that in my old bike. they don't come standard in the s3 1050 do they? if not then i got a really good deal on the bike.
When you paid for my pipes, you just bought me a tuneboy! The irony kills...
Tuneboy is much better than power commander, check out they're site. The software is a free download on the site, and you can get a feel for what the tuneboy is capable of. Being the tuner it seems you are, you could appreciate the difference. Most of the guys out there on Hondasakihas have no clue what a fuel curve or target ratio is, so they get a power commander because that is what everyone else has. That, and tuneboy doesn't support Hondasakihas! :devil:
20088Tune_dyno39 is for users with the Zard full exhaust system and BMC filter. No SAI
20088base2 is Devious' tune based on the 20088 dyno tune, but has a few slight alterations for added fuel for precatalyst removal from the stock header. Trident half system exhaust, BMC air filter, intake/TB clean up work. Prime pulse is 12800. Speedo correction is 106.5%. Rev limit is 9850 rpm. This tune and mods made 132.49 hp and 82.45 ft-lb of torque at the rear wheel (Dynojet). Not perfect, but this is a good starting point.
AlaskaS3's tune for the Zard slip-on, pre-cat & SAI removed, and headers port matched.
This is the tune AlaskaS3 has for the Zard slip-on, pre-cat & SAI removed, and headers port matched. Based off the 20088 tune modified with help from Devious.
SAI or Secondary Air Injection is an emissions system that puts air into the exhaust to help the catalytic converter burn unused fuel in the exhaust gases. SAI is one of the reasons for popping on deceleration. Removing the SAI isn't about gaining power at all, more like tidying up the system.
Here's a picture of the SAI solenoid and tubing. The tubing starts at the front of the airbox on the 1050 and runs to the solenoid. The solenoid then opens at times to allow fresh air into the exhaust.
The tube at the very top of the picture is where it plugs into the airbox. Once you have a non-SAI tune installed you can disconnect, block, or remove the SAI. The most elegant solution thus far is the block off plates available from our own Kuhlka.
Here are a set of his block off plates installed and the SAI gone:
Here's the SAI hanging out on a tool box before it completed it's journey to the circular file:
