Okay, bad wording calling this a tuner. I have a tuner on my bike, this will let me see what it is doing as I make adjustments. If not, well twenty bucks isn't a big deal. You guys are rough. BTW, it is sitting on the dining room table. Not a chance of it going back without trying it out.

(Isn't it pretty much the norm to get a hole drilled in your pipe when getting it dyno tuned? This seems like the least of my worries. ???)

No holes drilled in my pipes to Dyno a sniffer is used or you can swap out to wide band sensors

I'm glad you have a tuner and understood what this product is. I'd be worried that a gauge won't give you the reading accuracy to make fine adjustments but have in with it and let us know the outcome.

I'd be interested how from an analog gauge you will be able to read and adjust for wot, load, no load, open and closed loop just to start , the ecm is making hundreds of adjustments at a time

I was told by Chris at Dobeck that since digital gauges are typically hard to see in the sun that they have built a digital guage that displays in an analog format to correct for this.

I run a power vision and it has the ability to run Nd log data and rewrite the tune n it's own or for even more precise tuning it can be used on a Dyno.

If I were you as soon as it arrives send it back and do more research to get a real tuner that will help you out. There is a lo of good info on this site
+1, I completely agree. Also, a proper tune involves a lot more then air/fuel ration. The air/fuel is necessary when you put on a new pipe and breather. Your motorcycle is already designed to self tune as you ride right out of the factory. The goal is to bring all of the parameters together so they adjust themselves equally as you ride. You should also have both cylinders tuned to run together properly. Your engine can do things that you don't know about. There are some things you can't detect without a dyno tune or v-tune, such as pings. Even a professional tune can be done wrong if the person tuning your bike doesn't have the skills to properly interpret the datat. I'm not a technical guy so I may not be explaining this eloquently. Hopefully Frank (Drago) or Doc can chime in and better express my point. Bottom line, don't waste your money.

Edit: If you're looking for a gauge that will accurately read your air/fuel ration I would recommend the one made by RB Racing.

Just FYI, most shops drill a hole in your headers if they use a sniffer and you dont have O2 sensors or even if you do have O2 sensors and they are located below the trans area or if they use a probe type sniffer and you have a baffle that is not straight through to allow them to put the probe straight up the tail pipe. The closer to the heads the sampling can be done, the better. Harley sells these rivnuts out of their SE catalog. This is the best way to tune if you dont have the large O2 bungs near the heads or if the shop tunes with anything other than the large wideband O2 sensors. If you've had your bike tuned on a dyno, theres a good chance you have holes drilled in the front and read headers and a rivnut installed or the hole has been welded back up. Something like this....

Yes I have. Sorry for not getting back sooner.

Overall the thing worked pretty well. It had a Bosch O2 sensor, a little box that looked similar to the Dobeck tuner that I have on my motorcycle which converts the digital readings to analog, and a gauge that suction cups to the tank. It also has various cords to provide power depending on if you have a cigarette lighter, or need to connect directly to the battery, or into a battery tender plug, etc. It comes with the proper sized drill bit, the rivnuts, as well as all hardware needed to connect the thing as well as clear directions on how to set up and use.

The readings on the gauge were easy to work with, and seemed to pick up even the smallest changes that I could make with my tuner. Overall I got it running to a point where I'm very happy with it.

Before I sent it back to Dobeck we installed it on my father in laws Harley. He has done quite a bit of work to it, such as heads, pipes, cams, and God only knows what else. He's a bit of a cheater in this area. Likes to go fast, but look stock. Sort of old school I guess. Anyway, his bike was set up on a Dyno so it seemed like a good check of the tuning system I rented. Ready for this, the gauge was pretty darned accurate. I could see that when tuning my motorcycle that each adjustment on the Dobeck was changing the mixture in about .2 increments, IE 13.7:1 to 13.9:1, etc., but just didn't know if these readings were indeed accurate. We were able to confirm that they were indeed by comparing it to the way my father in laws bike was set up.

So now my bike is running good, and frankly like it should have from the factory. It isn't the fastest out there, but that isn't what I was going for. It just runs clean, is responsive, much cooler, and has power that feels linear when twisting the throttle. It is tractor like in the mountains and requires little shifting on twisty mountain roads even two up. It revs to redline quickly when getting after it which was only a dream when I started this journey. I'm calling it done. Time to ride.

Then you still need an actual tuner to make the adjustments. Nothing here that would replace my Thunder Max....
+1! especially after speaking with a couple of guys local who say the nearest good tuner is in Vancouver and I don't have a passport.

Interesting article. I was looking into one of their tuners but my new to me bike had the SERT already installed when I got it. They gave some pretty deep discounts to Military, Ex-Military, FD, and PD employees.

Seem like really good people. I think it was John that I talked with.
