Power Commander II

[OB_Earl]

How the heck do you know where to go with all these changes without being on a dyno or a ega? Us guys without those things could really screw up a good running bike. comments? Does the stock programming compensate for changing the exhaust?

Just picked up my Power II from Micron today. I installed it already but a massive thunderstorm just came in so I am grounded.
The P. commander is programmed from DynoJet for Micron. The Maps included are for the full system, S/ons, Stage 1 European bike, and stock. The P commander came with map .003 which for the full sytem micron, which is what I have. The map was set up on a Dyno at DynoJet to produce the smoothest curve and most power. 15 hp increase is what they claim on the Dyno sheet I have.
I will learn more Thursday once I work with the software more. From the limited time I have looked at it it seems that I can compare setings for the full Micron system with the stock, or any other map. Or, modify to my liking on a Dyno. It provides three tables 1. for fuel mgt. from 10% throttle to 100%, table 3 for small throttle position 0-5% throttle, and ignition timing, (table 4).All changes are made based on throttle position and RPM You need a pentium computer with windows 95/98. It locates under your passenger seat or hump and connects in between your ECU. You can make small chnages using the buttons on the P commander. I am assuming that others may have this unit but not with the settings for the Micron system? I suppose you could install it without a computer if you trust that the settings for the Micron system are good, and you have the Micron System.
I will let you know how it is on thursday and will be on the Dyno 1st week of August.
Five units came in today at Micron and all were sold.

Spent the first part of the week with a Yosh Ti - Rs3 race system on the dyno with the Yosh box and tried numerous settings,. The settings that provided optimal hp gains were ones far from the suggested settings from Yosh. I will post the run sheets as soon as we are done evaluating the Power Commander( those testsd will be on monday 26). Initial results with the Yosh box were a bit dismal and after spending a considerable amount of time and dyno runs did the pipe make considerable power gains when we went away from the Yosh suggested settings( 7hp gain) most improvement was in the midrange.

I hope next weeks testing will extract more power with the DynoJet product. All the information will be posted with the run sheets.

Performance shop in San Diego reports that the Yosh "advanced management" system zeros out its memory every time those electronic gauges do their full dial sweep when you turn on the ignition. Power Commander II apparently doesn't have this problem.

Yosh box settings were a bit differant from, what Yosh suggests. -5, -5,-5 provided the most gain on a dynoJet dyno. I know what you are going to say that is too lean and youi will cook the motor. Understand that I know this does not account for any ram air effects or wind drag on the bike, but these are the settings which provided the most improvement. A call to Yosh-USA after the results were in and guess what, they concluded the same findings. Well I doubt you will find any pipe mfg. willing to tell you to go leaner(liability). My bike was suspect to run a little rich stock, so maybe this can explain a little of this. I do not believe these will be the optimum settings. We tried all sorts of settings with the Yosh box, actually 10 differant settings. I just recieved the Power Commander II and will be spending more time with this product than the Yosh box.
Bob who has posted a very informative statement about the TPS being set correctly before you start any mapping makes a lot of sense. The Suzuki tools will be here friday and work with the Power Commander will commence after TPS corrections.

Yeah I know a paper clip will work and you can break out the pin in the screw..

terral are they saying that after you reprogram with the yosh box and turn the key off and on you lose all of the yosh program that you had put in ? burt

The yosh box updates the e-prom within the ECM unit (black box). The dynoject PCII inserts between the wire harness and the ECM, takes the e-prom reading and adds adjustments to them (that you made by a laptop, or pc2 panel adjustments) before sending them to the f/i & engine.

The Yosh box is "intrusive", that is it makes permenant changes to your system. Only way to restore to factory settings is to zero it out with the yosh box, or replace the ECM unit.

Using the yosh box, you switch the key off, connect the box, key on, program, write changes to ECM, key off. From that point on the settings are saved and will not change.

How did your results go? What final settings did you pick for the yosh box?
Are you still tuning with the PCII ?

I am more curios about the yosh box cuz my pipe should be here in a few days and I have the yosh box.

Thanks in Advance.
