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.

That's the best part, no install!

Tuneboy is software/cable that reflashes the ECU. Hook it up, reflash, unhook, and ride away!

Yeah. But if you have the PC3 already... well, it's up to you. Tunebwoy offers a bit more options than PC3, and is more elegant solution.

which has the better support for maps and custom tunes?

anyways, i don't mind spending a couple hundred bucks if tuneboy is the better solution but if i can't get anyone to tune it then it's be a waste of $$$ eh?

Tuneboy will definitely give you more options. It is not nearly as common so finding people to tune is slightly more difficult. The tuneboy can use the dynojet tuning link which is fairly common.

The biggest problem I have is finding people who will let me tune as they dyno. :mad:

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:

Is there any other place to get a tune boy cheaper? $529, geez.

So, if I buy the Tuneboy y'all are going to hook me with some map advice, right? What's this 20088?
Thanks,

20088 is a non-SAI tune for aftermarket cans.

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 is the secondary air injection system that dilutes the exhaust gases and causes the popping on deceleration. There is no performance gain from removing it, by itself.

Dfib got one of the tunes wrong above. The 20088dyno39 is NOT for the Zard. It is for high mount dual silencers. The tune that AlaskaS3 posted is a leaned down version of this tune.

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:


Hope that helps! :wrench: ;D

Edit: More SAI talk SAI Discussion
