I was wondering which system is the best buy for the buck. What are you guys using? I am saving up my $$ for the Direct link from Al, and there is nobody in my area that wants to tune my bike so I would like to try it myself. I do have access to a portable five gas analyzer, but I can't log TPS with it. It will log RPM. Thanks. | ||

I use the Zeitonix ZT-2 controller with Pocketlogger software on a Palm Vx. I got a cheep PDA mount that suction cups over the stock tach to hold the PDA. The pocketlogger SW has realtime readout so you can monitor your A/F ratio, RPM, TPS, and Engine temperature( or any other 0-5V input) while you ride and/or log. Got about $350 tied up in this setup and I've used it to tune both my street and race Buells. The street bike's stock ECM was tuned with DL and the racebike uses the factory programmable race ECM. | ||

Thanks. I think I'll go that route. | ||

Check out the Innovate LM-1 or LC-1 too. | ||

Ok guys, So is it just these three or are there any others that will be good for the Buells??? Now, If one has one of these and gets the direct link , can one use it to see where the air/fuel ratios are on the rpm curves and then be able to use the direct link to remap the ECM??? I guess one still can`t reset the TPS with any of the above??? | ||
| Brewtus |
Hogs, That is what I am after. I am looking to record RPM, TPS, and O2. The wideband O2 is very accurate, so if you can log all three readings you should be able to tune your bike. It will take some time because you have to find rich and lean spots in the recorded readings and compare them to your map, but it should be accurate. You still can't reset TPS or AFV with a data logging device. You will still need the VDSTS or Direct Link for that. XB9, one more question. Did you re-locate your O2 sensor, or did you use the stock location? | ||
| Hogs |
Does the DL reset tps and AFV?? | ||
| Brewtus |
If I have understood correctly, the DL does reset the TPS and AFV. If I am wrong please chime in. | ||
| Hogs |
Also does the DL do trouble codes or just the VDSTS, Guess what I am getting at does one need the VDSTS, DL, And a wide band unit?? what about this as well http://www.hardracing.com/Misc/WideBand.htm | ||
| Brewtus |
As far as I know DL does not do trouble codes. You will still need the VDSTS for that. The link you posted is exactly what I was asking about in my original post. seems like XB9 has the best solution for the money. The Innovate stuff that 650 was talking about looks like good quality products, but I am looking to go as inexpensive as possible. | ||

I chose the Zeitronix on price and size/weight. I think I researched them all. I used the stock location for the rear cyl, welded a bung on the front (Micron) for the racebike. You also need to log engine head temperature because you need to tune within a defined temperature range. (Message edited by xb9 on June 14, 2006) (Message edited by xb9 on June 14, 2006) | ||

Have a look at http://www.innovatemotorsports.com/ we use the LM 1 for onroaddatacollecting. Its starts in the USA at 349 $ for A/F only and you can built it up to a full system with rpm/TP/Temps etc. For datacollecting on the racetrack we recommend http://www.aim-sportline.com/ with the the MXL series you get also lambda values. Onroad/ontrackdataaquisition is the key to tune your engine. Jens | ||
| Hogs |
Heres a stupid ?.. What is the difference in LAmbda values, and A/F values? How do you use one over the other etc.etc...?? | ||

Take your time and choose carefully so you only have to buy it once. It depends a lot on if you want it for your own bike only, or if you want to be able to test several or many bikes. If you are thinking of a big bore/stroke motor then first you need to think about how you are going to control the fuel, and find a wideband set-up compatible with the chosen system, assuming it can datalog. Usually that is the cheapest way in the long run. Another way to do it is with a standalone datalogging system which will not be that cheap and all it does is datalog, so you're paying for software and hardware that already exists in most fuel injection controllers, but this would be a good choice for testing/datalogging many bikes. Usually datalogging involves a fair bit of computer/laptop usage so skills are needed in this area, and often the wideband controller outputs a voltage from 0 to 5V to represent an AFR (or Lambda) from a to b which you can program into it via a serial cable from the laptop. For example you could make it 0V = 10:1 AFR and 5V = 20:1 AFR, or 0V = 11:1 and 5V = 16:1 AFR. So the output from the wideband needs to match the datalooger's input or the software so the figures come out right on the computer. There is a manufacturer's default output that the unit comes shipped with that is usually recognized by whatever is doing the datalogging but ask questions before you buy. Some setups require a laptop to record the info (do the datalogging) some have memory built-in (but how long will it log for?) some use an old Palm handheld (small). How much memory do you need - well how long does it take to get to redline in 3rd or 4 th gear on a stock XB12? (several times) I think most wideband controllers have datalogging but they're all different, the TechEdge controllers from Oz are worth a look too. After you do the datalogging it needs to be transferred to a computer and displayed using more software. Check that the price of the software is included (usually it is, or it's free, but check anyway). The cheapest way to monitor AFR while riding, IMO, whether logging or not, is to have a wideband controller set to 0V = 11:1 AFR and 5V = 16:1 AFR and have it drive 10 LED's, each one indicating a 0.5:1 change in AFR. The Innovate LC-1 costs around US$200 and is a controller/cable with the sensor, about the cheapest you can get but seems to do the job well. Ian. (Message edited by opto on June 15, 2006) | ||

Thanks for all the info. This will help a lot! | ||

I have the Daytona Sensors "WEGO II" it displays A/F as well as recording it along with TP and RPM. You can vary the data compression from two hours down to five minutes and there by record a run down the road or a 20 minute track session. ... Terry | ||

This is important to remember. You need a way to read the O2 from the front cylinder because they need to be tuned separately. The values are suprisingly different from front to rear. | ||
| Hogs |
Thanks Opto,Terry and all...... So is it important to have two 02 sensors for the wide band for the front and rear cyl. OR could one just install a 02 for the wide band down on the header just after where both header pipes join together, and just before where the muffler joins, which wd. give you an average of both cyls. or better to have two separate ones, or is this over kill for the street, one wd. be fine???? Thanks again .. this is some of the best knowledge we need to keep on top of these motors , especially when one wants to increase bore, cams, heads and so on... Funny thing is, I seem to get bored with stock set ups and bike in general , always have to do something to take the boredoom out of the picture, See what is released for 07 maybe a whole new bike setup etc. | ||
| 99buellx1 |
They need to be tuned separately. If you are getting an average, you may be running extremely lean on one, but rich on the other, and everything could look fine. Also, if you are reading a mixture, how would you know where changes need to be made? | ||
| Hogs |
So one can make changes to each cyl.for fuel,Hmmmm Seems to be getting more techical all the time, Wheres that carb at.. | ||
| Jerseyguy |
I'm with Jens on this one.   I use the Innovate Motorsports LM1 with Auxbox. The Logworks2 software that comes with it is excellent as well. If you go to www.kdfab.com and navigate to the XB9 with TFI on the road data page you can see some Logworks1 data I took last year. The new version is even better. I'm in the middle of testing the Drummer Carbon Fiber on the road right now and will post my results when I'm done. | ||
| Hogs |
Hey Jerseyguy, So you are 100 percent happy with that gear, and one could easy set up a ecm with it and the DL, No plms. seeing A/F ratios etc... What does the Auxbox do as well... and...Wheres the Canadian FLAG LoL |
