The technical morass of tuning
07/12/16 8:45 AM

I've had the PCV and Auto Tune on the bike for 5-6 years and I haven't touched it except to install a couple maps and accept one AT adjustment. Never used my LCD-200 yet. This stuff is so complex if you really want to get into it that I doubt many people even are aware of what they can do with there PCV. I had to call DJ ytech support 4 times yesterday. Last time, I heard a lengthy sigh before the guy said, "Hello, Dyno Jet technical support, can i have your name please.....same spelling as the last time you called?" LOL Sorry, I paid enough $$ for all these gadgets and I do intend to figure out every last thing that they do.

I'm going through the PCV with a fine tooth comb right now and will do a write up that covers everything step by step. It's too bad there are not more people using PCVs these days but I do see why part of the reason for favoring a flash is the simplicity. Hopefully we won't loose sight of the value of products like the Power Commander, Auto Tune and Ignition Module. I'm diving into it.

Velcro and blue tape are very low tech but they work wonders.

I think I read somewhere that dynojet pcv can be used from a phone now. Dynojet c3 app?

You need a cable, anyone know what type to get for it to work on an android phone? Could it just be a normal usb- micro end thingy that you use to charge one? They say you need a On-the-Go USB cable, but I cant seem to find one to buy. I must be missing something.

Don't know? Worst thing that could happen is that you charge your phone off your PCV. Actually it is a normal USB cable that hooks up to the PCV. If it fits your phone and you can use it to hook up to your computer, I'lll bet it would work with a PCV.------second thought, if you have a cable for your phone to charge or connect to computer, the USB plug always goes to the computer. The PCV has no USB plug port, the USB plug needs to go to the external device and the small plug goes to the PCV. Might work if your phone has a USB plug port. Just hook the cable to the PCV and plug the USB end to the phone.

The phone ap would be nice and compact but damn--can't imagine pressing the buttons on a touch screen or mousing on a Iphone. The laptop was tough enough. Also, a little tough to see the lap top display in the midday sun.

found what is needed. I assume then all I have to add is the cable that my phone normally uses.

Rook,

You definitely NEED to hookup and use that LCD unless you are able to ride with the laptop connected like that and don't think that I hadn't considered the same thing several times myself. :)

I bought the POD300 a couple of years ago now and setting the target AFR tables and seeing what the engine is actually doing at that moment in time are 2 VERY different things. Using the POD300 I found all sorts of spots that the fueling wasn't right and I used the logging feature (for a few seconds) to capture the data, pull over, connect the laptop, make the changes then continue down the road to check my adjustments.

3 pieces of advice, firstly, check the AFR, RPM and throttle position at the same increments as the PCV (ie TPS: 0%, 2%, 5%, 10%, 20%, 40%, etc) and make your changes to those cells in the fuel map.

Secondly, there is an alarmingly LONG delay between changes in the exhaust gas to when the autotune registers the changes. I could feel the bike lagging at a certain RPM, then 1-2 seconds later (or 25 to 50 exhaust strokes later at 6000RPM) I could see the change in the AFR on the screen. So, when making changes check the cell just before you start seeing the issue (ie, you log its lean at 6250RPM, change 6000 & 6250).

Lastly, if you are going to start doing some manual fine tuning, set the high/low allowed trim adjustment on the autotune to 1% (minimum it will let you) otherwise the autotune may simply undo the changes you just made.

rod442,

I installed but never actually used the phone app for the power commander because it only supports 1 device at a time and it won't actually display data from the PCV like a laptop or POD300 does. I figured it would be WAAAAY easier to simply strap a laptop to the back of the bike and connect it each time then it would be to disconnect the ignition module and my autotune every time I wanted to make a change.

The LCD will be the very next thing I put on the bike. I'm sure it wont display the PCV software though so the laptop will be on the bike too. I was attempting to set the speed and gear calibration with the laptop but I realized that it was required to have those sensors tapped into. I thought they were connected through the stock harness. Nothing accomplished but good practice for the future.

I was not aware of the feedback lag. I will have to learn to deal with that. Sounds like a good idea to make max/min trim very low like you mentioned. If the map is close to begin with, IDT it should take too many runs to zero out the trims.

Thanks for the pointers.

I bought an LCD-200 back in about 2010 (I think)and have yet to use it. The real time devices look fairly simple if you can get the PCV software down and hook up a couple wires. I've gone through every aspect of the PCV program and am just about done writing a tutorial. All the info is already online but the procedures are very brief and sometimes lack explanation. Some things are not explained at all but you can call DJ tech support a few times before they get tired of you.
