You might contact Dyno Jet for a recommendation on someone in your area or llok here on this sight at the dyno tuner locator thread.

I'm a Cleveland, OH native, but I've been in Frederick since the army dumped me here in 2011. Working on finding my way back home, hopefully in the next year. Good to hear the dealer may be willing to give her the tune she deserves and not what the EPA thinks she needs. I'll talk with them more next week and see if their tuner can offer any references.

Current status: No change. Dealer said the ECM would be there on Aug 26, but they still haven't received it.

I believe I have the 18mm bungs on the V&H exhaust, based on what I could find when I was looking at the Target Tune kit. Can't verify it until I get the bike back.

It may be worth mentioning I also have a '98 Honda SuperHawk and my grandpa's '78 Kawasaki KZ650 in the garage. The KZ isn't going anywhere, and the Honda was a trade that I'll probably resell in the Spring (or trade for a Ninja 600). The Harley was purchased as a 2007+ specifically for the EFI/Delphi to be my 'daily' bike that I could rely on versus the two old carb'ed bikes. I, personally, don't want to do a thing with the tuner. I just want my bike working again with the peace of mind that it's running correctly and not, for example, melting pistons as I ride. I'm willing to pay the price for parts and service to achieve that goal. My struggle is in identifying the most practical approach with regard to this situation. I've also considered writing the damn thing off and trading it in toward a '14+ Road King, but that wouldn't be a practical decision right now in my life.

You have, however, identified pretty much all my positive thoughts about the Thunder-Max. Full disclosure: Tmax pretty much told me to be careful selecting my base tune, and then run it til it runs right. FuelMoto on the other hand told me neither option is going to solve my problem without a reputable tuner and a dyno session. I understand timing is something that will need to be dialed in either way (not auto-learned), and both local tuners have expressed a preference for Dynojet's offering. That's why I'm leaning that direction. As for myself, I have no experience and no preference. I just want to ride again before everything freezes.

one of the great things about today's technology is that we have so many options. The problem is, we have soooo many options! Good luck with finding the right path for you, and let us know what you decide.

Hey folks! It's been a while, but I finally got the bike back from the dealer after a slew of supply chain issues. I went with the DynoJet PV-1B and had my local dealer dyno tune it.

I've only ridden it home from the dealership so far, with a couple brief stops along the way. But the starter/compensator kickback is horrible! I'm using my MCRs, but it's behaving as if I'm not. Is that something that could/should have been addressed in the tune?

I paid for my own module and license, so I have full access to my ECU, but I don't have any experience tuning EFI. If there's a place I can upload the tune for review and opinions, I'd love to get some insight from people who know what they're looking at.

(Still riding, by the way! FirstGear is keeping my *** on two wheels any time the roads are dry.)

Sounds like you bought your PowerVision from the dealer.... too bad...

I believe you can still buy lifetime map support from FuelMoto...

Call them and see... or you could also call DynoJet for assistance, they've helped me out in the past too.

FuelMoto map support is very good. On a couple occasions I've done some data logging on a tune that had a couple issues. I sent the data log to FuelMoto with a description of the issue. They looked over the data log, made some adjustments, and sent me back a tune tweaked to address my issues.... It worked great for me..

If you have a PC, you can download the WinPv software form DynoJet, and then read, explore, and/or change the tune yourself on your PC... I don't do much tweaking on my own, but love to compare different tunes (AFR and Timing) to see how they differ...

The dealer told me the PV-1B was discontinued and they couldn't get it, and they offered to sell me a Power Commander instead. So I ordered the PV myself from FuelMoto and brought it to the tuner. Because I couldn't get a base tune from FuelMoto, due to not knowing any of the engine specs, it completely slipped my mind that they offer support on the back end! Rookie mistake, thanks for the reminder.

I've already downloaded WinPV and compared the base tune that they started with to the final tune they flashed to the ECM. I understand what the numbers represent, but I don't have the knowledge to judge whether or not they are what they should be. I'll send an email to FM with the tunes attached and see what they say.

If anyone is curious, I've also attached them to this post. Just change the .tun extension to .pvt on each file to open them in WinPV.

PV-1B, PV-2B and PV-3B are all the same unit, but ship with different cables to connect to the bike. PV-1B and PV-2B use the same firmware for 01-20 bikes, PV-3B uses different firmware for 2021+ bikes. Any device can have either firmware put in it and any cable connected, to work on any of the bikes.

You may or may not be able to see the IVO and IVC values of the tune. That's specific to the cam you have and the first thing that needs to be correct to start tuning.

I'd like to help you but How can I change the file extension be able to see it in Power Vision? Or can you repost with the proper extension?

Hey @98hotrodfatboy

I don't use PV but I'm always trying to learn. I had a bit of an issue downloading the files but here's what worked for me. You may already be ahead of me on some of this.

1. Click on the link, which will open another window where you are asked where you want to save the file. Just save it as a ".tun" file on your computer somewhere.
2. Then, go to where you saved the file and click on the title. You'll only want the ".tun" text highlighted. Then type in ".PVT" instead. Hit ENTER.

That makes the extension readable by the PV software. At least, that's what I did.

Hope it helps. And looking forward to learning with the others from the software knowledge-base.

Ok I have the file opened in PV.. They have the engine listed as a 105" motor with injector size of 3.91. It would be hard to determine engine size with out measuring the bore and stroke.. Pulling the cams and looking for a stamped number on the end would help along with a compression test... Do you have adjustable pushrods?.. It would be easy to pop one of the cover's to look.. Also if you post a pic of the cam chest side of the engine I can tell you if the tubes were changed out to accept adjustables.. There is a considerable difference in VE's from front to rear cylinder, I can make adjustments to that but it would only be based on speculation.. I suggest you try to get a hold of the person or previous owner to try and find out what you have in the motor or you will have to disassemble and measure.. Al so now that is it running can you describe any symptoms at any speed. How does it idle, Is it running hot, is it popping on decel, does feel like it's lacking power? what do the plugs look like and start with new plugs.. Your timing tables look ok but your AFR's are a little lean. I can change all that but I need more info on current running condition.

If the cams are unknown, there's no way to have the correct crank tooth setting.
