WOW..

It is truly amazing where the technology has gone in the last 2yrs. These tuning devices offer so many options to the user. It is also very evident that one could cause harm to there bike if not educated in its adjustments.

I have been looking very intently into which tuning tool to purchase. I was very close to pulling the trigger on the TTS. Then the PV came out, the REV PERF has gained a lot of popularity recently on this forum (with Fuel Moto joining forces-which means its a quality option as well) it's a tough decision. With all that said the PV maybe the most simplified interactive tool available. With the pro and basic auto tune addition coming soon its a winner that IMO others will chase after (similar to the iPhone a few years back-now others of course have caught them) The jury is still out on how far the PV will go and what hiccups will appear but WHAT A PRODUCT! In the end the public is the real winner. Its not cheap but what is.. Sorry for the rant but its pretty cool!

I'm using Front Knock Retard and Rear Knock Retard. This shows how much retard is being used by the knock sensor to address a knock event. It isn't too practical as a gauge, as the events pop-up quickly and you must watch the gauge too much, but when you datalog you can see everything and where it occurs (KPA, RPM, TP, etc.). I have an event at around 60KPA and 2000-2500 rpms on the rear cylinder and have been trying to tune it out, but am thinking it may be a false event, as it keeps popping up. I hate to keep pulling advance out but will keep working with it.

Where are you finding these Firmwares? I am still on 644

My wires are original and I was using HD standard-issue plugs with around 12k miles on them. OTOH yesterday I changed the plugs to HD Gold, and oddly my knock-retard has moderated considerably even though I raised the spark values up to the levels I was using before the adjustments. I'm not necessarily linking the plugs to the change but I do wonder. One value in the affected range is 11° higher now that it was yesterday, so I based my suspicions of false knock events on this.

I had thought about changing the plug wires, but I don't really have any evidence they are causing trouble and the issues I have now are not major, IMO. Besides all that, the bike is running very well indeed. If wasn't analyzing ECM tables and datalogs to a fault I would never know it was having any problem at all.

This is another subject, but I used two sets of Autolite plugs (one heat-range colder than stock) up until about five months ago and had problems with them. So I re-installed my used (8k miles) HD plugs at that time and have been running them since October.

FW 644 is the last authorized version. The beta FW can only be obtained from the PV developers and can't be downloaded from their website. You could email them and ask, but I don't think they are issuing these beta releases unless they are testing specific problems reported by users. I do expect a new FW release fairly soon, as soon as DJ is sure it's ready for prime-time, and it should have the features we've been talking about here. There is some risk to running these beta releases, so you can't blame DJ for keeping a tight rein on them.

Thanks I'll keep checking. The new stuff sounds cool.

I asked DJ about an approximate date and was told they didn't know, but when I hear something I'll post here. I suspect they are working on an average-MPG gauge that doesn't stop when powered down and can be reset at will. They will retain the instant-MPG gauge, which is very good news to me, and will add a second that averages in some way. They already have an averaging gauge working but it only works between power cycles and I think they want to make it a bit more user-friendly.

I have really enjoyed reading this informative thread. I just ordered a PV from Jamie at fuelmoto yesterday for my Sportster. Can't wait to get it and see how the new tune works. Where on the bike does the PV plug in so that the map can be flashed? Does it plug into the data link port?

I don't know where the J1850 port is on a Sporty, but it's under the left side-cover on '07 and I believe the right side-cover on '09 and above FLH's. Your service manual will identify the location, but you could pose this question in the Sporty section giving your year-model and someone will undoubtedly report back an answer.

KPA is just a unit of pressure. 100 kpa is the pressure of the atmosphere at sea level. What's being read in the software, and used as the x-axis for most tables, is an absolute pressure value. If the engine is in a vaccum condition, the value will be less than ambient pressure. If the engine is at WOT and there aren't any intake restrictions, the value should be the same as ambient pressure.

Quick example, 100kpa sea level pressure, engine is idling at 30kpa. The engine is pulling 70kpa vacuum below atmospheric, converted that's 20.6 inches of mercury, which is what you'd read on a vacuum gauge if it was attached to the engine.

A vacuum gauge is "gauge pressure", so it's referenced that ambient pressure always reads zero on the gauge.

Pretty square guide up front on the first page, (thanks). I bought my PV a couple weeks ago when I knew the ECM was going to need flashed. It was either pay the dealer $189.00 for a one time flash and not know what the settings are or were, or buy the PV and keep my factory settings and know what the new settings were flashed to.

My 2011 Ultra runs like a champ. It even shifts without that annoying "clunk" now and has improved my gas mileage by 60+ per tank. I couldn't be happier with it. The second reason I bought it was the fact that it is technology and it is the latest and inovative way for users to work with their own bikes. Jamie at Fuel Moto was pleasant to work with along with the rest of his staff.

The fact remains, I don't have to pay the dealer any money, "ever" to flash my ECM when I'm ready to do the next mods to my bike. I did Power Duals, Monster Rounds, and a Stage I Sreamin Eagle air cleaner kit. $499.00 and I believe I will save money in the long run. Highly reccomend this product.
