The "What's in the AF1 shop" Thread

[JAndrewG]

So we were speaking of pressures a page ago, you mention that the Smalt shower set up (which is very cool looking) uses the OEM fuel pump. What's the stock system run for PSI/Bar? I'm surprised it can do the extra volume, as the stock injectors alone are marginal in the larger big bore kit. Injector volume vs. fuel pump volume are two different things, but interesting that the latter is actually up to much larger injectors and even secondary ones?

[JAndrewG]

Oh, and yeah that little smog pump is neat. Me too, always thought the smog pump answer to our government's new save the world regs in the early '70s was ironic. No less emissions... let's just water 'em down a little to get by.

Forgot something I've been meaning to ask you Micah. Have you ever done the tuning you were going to do on Axecent's Tambo?

I picked up a 339 mile '05 F4 1000 S a few weeks ago and have been learning about the eprom thing with the 16M ECU. There's a guy on the MV forum from the UK that custom writes them, can change the timing, fueling, when the cooling fans come on and shut off, and when that stupid EBS thing kicks in.

Seems he found that all the early MV 1000's ('05 and'06) with the 16M have the Tambo's secondary injector tables in them, they just disabled it on non-Tambo bikes by setting them to come in at 16k rpm. Since the bike is set to rev limit at 12,700 it just never happens (is the Tambo rev limit a little higher? Don't know...).

Anyway, he's also written software he's giving away if a guy wants all that imperical knowledge for himself and wants to do these things on his own. Thought it might be of interest.

On the other hand, I know Gabro here is the eprom guru for the early Aprilia ECU. Are they also the 16M? Hell, you probably already know all this stuff.

There's another guy in the UK that builds a direct plug and play Microtec ECU for the early bikes, and I guess that'd also do away with any of the typical add on modules too. Let's you control everything and in a much more sophisticated way.

Jeez... post hog that I am this morning. Guess I'm doing my part to get this thread to 1,000,000 views!

Air injection pumps do not just dilute emissions with no reductions. The whole point is to reduce unburned hydrocarbons which they do.

That supercharger looks awesome. I need to find one for my scooter!

KZ, how do they do that, other than simply dilute the exhaust? It's been so long since I looked at a 70's smog system, does the pumped air go in soon enough that the heat and extra oxygen help burn hydrocarbons?

[kzmille]

...does the pumped air go in soon enough that the heat and extra oxygen help burn hydrocarbons?

Yes, that's it.

[banzairx7]

The injected air also helps under rich conditions when there isn't enough air in the exhaust stream to support catalytic reaction. That was more of in issue back when carbs were still used and air/fuel mixture was impossible to control as tightly under steady state throttle cruising conditions.

[Hellgate]

It was tough this week...after taking out the Austin DEMO first thing last Saturday, I almost did just that this past week!

And you resisted? You are a stronger man than I Sir. I've been I Mexico all week and get home tomorrow. The trip was great but I want ride!

Thanks for the info.

Hey Axecent, you're welcome.

Check out mvagusta.net. The guy that's doing the eproms is merc07. He has a post with the software available to download.

I would think the cool thing for your Tambo would be to put the Microtec on it. The UK guy that has a direct plug-n-play unit is X81, and is a site sponsor with a business called X-Bikes. I guess you can do anything with it. Micah could tune it on his dyno and adjust any parameter you would need.

Arrow makes a cat delete mid pipe they seem to need, and an aftermarket air filter such as MWR helps too. Putting the bike back to stock would be a simple matter of swapping back these three parts.

My bike is just a standard F4 1000 S, but is so clean and new I want to keep it stock. I'm doing the custom chip, mid pipe, and filter. The chip is being written to turn on the fans much earlier, raise the RPM that the EBS comes on, advance ignition timing at low to mid RPM, and adjust fueling from emissions stoich in this area to more like 13.2 AFR. He worked out the ignition and fueling tables for a 1000 S on a dyno a few months ago, so it should be close enough for me. As it is now, the stock fueling is just terrible.

[JAndrewG]

Here's a thread X81 started on the Microtec, the 1000 S is referenced starting in post #5. http://www.mvagusta.net/forum/showthread.php?t=45281

There is also a tool to write eproms for the stock ECU, and a UV eraser to clean them first is available. With the software merc07 wrote, you could simply dial it in that way.

With either option you avoid any add-on like a PCIII, and can adjust anything, not just fueling.

i'm in contact with the microtec guys: http://www.microtec.cc/cms/index.php
they are presently working on a replacement ECU for RSV4

[The Foreigner]

I keep telling myself it doesn't have enough range, the seat is a plank, the front fairing is hideous, and they're not bringing the semi-attractive gray one to North America. I then tell myself that my 2003 is a great bike that does everything I need it to do, and the Rotax twin already has more power than I need.

Then I see a few more TV4 videos, read a few more reviews and threads, and tell myself to take Micah's advice and stay the hell away from the local dealers if I want to keep my rainy day fund intact.

Funny, that is exactly what I do except I just add that I've just "invested" about 1.5k eur more in my 2005 one and I don't need anything else..for now !

how can i tell what i might have fried when i as a last resort jump started my rs 125 off a car? it still rides but the screen tach ligths etc dont work
