Good job, keep it up!

So how will this work having the WB2 and diode jump on the unit already if both ports are already taken.

DynojetResearch

Each additional module also has 2 CAN ports, so you can continue to daisy chain them together. For instance, the CMD has 2 CAN ports, as does the WB2. To connect the two, you would run the CAN to CAN cable from port 1 on the CMD to port 1 on the WB2. You would then install the CAN termination plug in either of the remaining open ports, which still leaves one port open for the next device. Since that device will also have two CAN ports, when you plug a CAN to CAN cable into one of those ports, you will still have one open port in the chain.

I see.. I doesn't have to be in a expecific order as long they are connected to a CAN?
Because all I have is one CAN connector open in the WB2.

But u guys know how to make it work .. I just like to know how everything work.. Always being that way..

DynojetResearch

That is correct. Location of the open port doesn't matter. Once it's on the bus, it's available.

Thank you!! So the autotune will affect the tunning done in the car? I assume it reads the WB2 data and adjust the map itself in the CMD? I'm just curios how will this affect the current set up..?

whatnot

correct me if I am wrong dyno....
The AutoTune is said to work by the CMD reading the WB2 data and creating a closed loop logic based off of the AFR that you tell it (the CMD) you want. So yes, it will prabablyaffect your current setup (unless your current setup has ou running one constant AFR as of now), but it will pretty much do a better job than your current setup much faster than you can with much less runs.

DynojetResearch

Nooner has it. Once the AutoTune feature is added to the software, you will see a new section called AutoTune. In the AutoTune section, there will be a Target AFR table and a Trim table.

You set the Target AFR table with values of A/F ratio you want the car to achieve, based on RPM and throttle position. Once you start driving the car, the CMD will look at the WB2 data and compare it to what the target is, then create a "trim" for each cell. This is what populates the Trim table as you drive.

The next time you connect to the software, you can view/edit/delete the trim table, or apply it to the base fuel map. That will then zero the trim table back to all zeros. Each successive drive cycle should result and smaller and smaller trim values.

Are there procedures that you recommend so that Autotune isn't overshooting the target AFR and creating a saw-tooth fuel map?

You make it sound very simple, but in reality no autotune is perfect, and still requires an experienced auto-tuner. Not saying that it will be difficult to learn, but it's not the end all to tuning, and won't be as simple as a click of a button. And this is only on the AFR, not including ignition, etc. Am I wrong?

im gonna guess that its used the same way that their power commander uses it on street bikes. if that is so i know a few people who use it and it works just fine for them on their bikes.

WOW ..now i gotta start saving up some more add-ons ....T.T.....

well any new maps yet??? ( dynojetcmd.com have 0 map and 16psi maps...).....( i have old 16,20,24 & new 0 , 16 maps..)

So does the AutoTune affect the OEM closed loop fuel learning logic?

So.... With the CMD and the WB2, you can pretty much PnP and drive around for a bit and then have a basic map to mess with?

Sounds interesting

McFly

^Correct, except that the autotune feature won't be out till late Dec/Early Jan from Dynojets estimate.

I thought you would have to drive and AutoTune would give you a base of which to fine tune from, but this sounds way better! I didn't even think about smaller trimming each time, sweet.

DynojetResearch

The AutoTune feature does not instantly correct to large values. Much like the programming of the stock ECU adaptive learning, it will slowly add values to affect change. It also has limits as to how much trim it can apply, so there is no worry of bad data that could cause big changes in A/F ratio and give a problem.

The beauty of AutoTune is that it IS very simple. Create a table with the A/F values you wish to target and it does the rest as you drive.

It will work exactly the same as the AutoTune in the Power Commander V for the street bikes. Good catch.

Well, it could if you put targets in areas where the car was still in closed loop. However, you'd basically have one system fighting another. Typically, if a car has to trim too much, it will set a CEL also. Where that might be beneficial is if you knew what the target A/F ratios where, and were installing larger than stock injectors...you could have the A/F target set the same as stock so that the stock ECU trim table would essentially be zero, giving it the most latitude of adjustment.

For A/F ratio, yes.

That's very reassuring and sounds very good.

So the Auto tune is for open loop then? That would make sense. But if it is used in closed loop too that would not.

I am pretty sure the CMD is only operational during open loop ECU.... but it used 'closed loop logic' in that the AFR stays constant and the other values adjust to maintain that. Just as Cruise control uses closed loop logic to maintain a constant speed while other variable change such as load ect.

I am assuming my reference above to closed loop threw you off?

DynojetResearch

The CMD should only be used to trim/AutoTune (go closed loop) in areas that the stock ECU is in open loop; however, the CMD is not limited to those areas - so if you did specify a target A/F ratio in areas where the stock ECU was still in closed loop, the CMD would still try to trim to achieve your specified target AFR.

This may be beneficial if you know the original closed loop targets and happen to run larger injectors. You can then tell the CMD to target the same A/F ratio as the stock computer, therefore keeping the stock trim values quite small.
