TEKA vs PCIII vs Yoshi

[moz]

What do you guys think or know about the TEKA SFI FI tool? http://www.factorypro.com/
It seems to have more features than the PCIII or Yoshi tools? Though it is not cheap.
I noticed that JHS reckoned that because it is 16bit it has trouble communicating with the SV's 32bit Processor.
Are there any other alternatives? i.e. software based programmes which can be run from your laptop? My old Speed Triple could be remapped this way.

easy now,

Moz,
I am also looking for laptop type software to do the job when the new cans go on. So anyone out there got any info??

Nico :wacko:

PC III's in essence are software re-mapable (spp?) by design...and ofer adjustments over an extremely wide range of throttle position/rpm conditions... though I must admit I am not very familiar with the TEKA unit.

We have just taken delivery of the new power commanders for the sv1000 plus the sv650 and you will need these to sort the fueling both priced at £284.35 inc vat @17.5%. These must be the first in the UK.

How's about an "Idiots Guide To Using The PCIII" ??

Now am am excited :rolleyes: But IMHO, no Power Commander should be sold without including at least 3 runs on a Dyno 150 or 250. It will take a minimum of that many runs to get close to the correct tuning. I myself wouldn't try to "seat of the pants" tune with a PC. Of course any shop with the Dyno will want to charge for the dyno runs and the tuning time....and if they know what they are doing, the results will be well worth it...

The TEKA unit remaps the stock ECU, so you don't need to keep a piggy-back unit on the bike. You should not have to purchase one, just pay the tuner who has one for his time to custom map your bike. Basically it modifies the fuel injection in the same way a PC3 does, but instead of adding a correction factor to the fuel injection data, the "real" map is modified.

Any folks out there have a remap of there SV with a TEKA unit? I would rather pay $50 or so to have the bike remapped instead of shelling out $250 - $300 for a PCIII especially since I have heard so many problems getting things mapped up right.

Check out TLR Planet. They have a listing of the TEKA settings used by there members. That is were I got mine and the SV feels really well dialed in.

I've bought a TEKA & done a bit of tuning with it. I'm now getting just on 115 rear wheel BHP with significantly better throttle response than a friend's otherwise identical SV.

Pros: No intermediate computer (PC3) to slow the engine management process or get damaged. No extra connections to be improperly done or to go bad. No laptop needed to do the programming (although you can do crude adjustments onboard the PC3). Can do everybody else's fuel injected Suzukis once I've finished mine - might soften the cost of the TEKA.

Cons: It's very difficult to significantly change the shape of the fuel maps with a TEKA. The TEKA costs more than a PC3.

The SV EFI has it's maps contained in one section of the engine management computer, then in a subsequent section there is a correction module which takes the outputs from the likes of the temperature sensors and uses them to modulate the basic maps. I think the TEKA tweaks the correction module, so the basic mapping remains unaltered. This is only a problem if the stock mapping is unsuitable for any reason, but with a heavily ventilated airbox lid, K&N filter and free flow mufflers the mapping of mine still seems just fine.

For what it's worth, these are the current settings which I'm using:

Idle Plus 10% fuel
10% throttle Less 7%
25% throttle Less 10%
50% throttle Less 10%
75% throttle Less 15%
100% throttle Less 20%

I believe that the idle setting is the datum on which the larger throttle positions build, therefore by adding 10% fuel at idle (which is set lean by Suzuki for emission control purposes) and then progressively taking it out we end up with a 100% throttle setting which is in reality richer than the raw figures would indicate, but still significantly leaner than stock.

I dyno'd it with a slightly richer settings than it currently has, and the a/f plot showed that with the exception of the lean patch between 4000 & 6000 which you will see on most of the SV dyno charts that have been posted, it was still a bit rich right through.

The other night a group of us went for a really fast blast which involved me trying to keep up with an 04 R1 by using an unusually high amount of full throttle in the mid rev range. At one stage the temperature gauge was sitting on about 92 degrees for a while which might indicate that I need a bit more fuel in the 75% to 100% throttle area. On the other hand, this temperature might have just be the result of the SV's rather scrawny cooling system.

I bought a TEKA because the concept of using a second computer to "correct" the output of the first computer appears pretty stupid to me, a computer technician. It makes much more sense to tell the first computer to do it's job properly. I had also heard quite a few complaints of poor running after fitting PCs although to be fair I would guess that this is more to do with poor installation or poor siting of the PC rather than inherent faults in the PC - if you go cutting into cables without knowing how to make perfect, weather and vibration proof joints you will quickly end up with something which looks and behaves like a product of the British motorcycle industry of the 1950s.

So, if you have access to a TEKA, my suggestion is not to bother with a PC3. Just make sure that you do get the exhaust gas analysed once you have made your changes. And before you do the exhaust gas analysis, disconnect and very very carefully block off the PAIR intakes on the cylinder heads. It is not sufficient merely to clamp the pair hoses!!!
