Installed it in 30. Minutes everything fit right and it works great I richend the fuel mixture the bike has more power better throttle response and runs cooler it does what it is suppose to do.

Took less than 30 minutes to install. It really works well and allows you to dial in for specific air/fuel and ignition changes. Put Screaming Eagle II slip ons onto my 2007 Sportster.

Because 2007 was the first year of EFI on the Sportster 1200, this is the option. I even called our local Harley dealership and Service center prior and they confirmed this. Very well made and user friendly. Let's you really dial in Stage 1 (pipes n air) without PC. Love the option of an interface if I go Stage 2 and 3. Less than 30 minute install.

I found the Daytona Twin Tec Tuner to be easy installation as long as you follow the instructions. Having been an automotive technician for many years then switching career paths to computers and Electronics. This device was not difficult to install. The only thing I would recommend as you remove each of the wires from the ECM Connector put them right into the Deutsch plug while you have that wire in your hand. This will help avoiding making a mistake. This is just my opinion. Other than that I found the instruction to be very good. After the installation setting the initial setup and making adjustments to the settings is easier than changing jets in a carbureted engine

So far so good. Seems of good quality. Install was not very bad at all old twisted stiff wires had to be gentle but got it done. Have played with tune and has relieved that lean cough. Still playing with it for mire fine tuning.

Was cautious about this purchase not making a difference on my bike. Easy install, and this tuner will bring your bike alive. So many changes right away and I can feel the minor horse power gain. Great purchase for the money!

Was very impressed with this less expensive little box. No more spark knock and I'm no longer running lean.

Good instructions, easy to wire-in. Excellent customer support from Daytona Twin Tec. I set recommended programming from included chart and solved my lean condition. After I install the S&S 509 cams I'll take her to The Dyno guys for a tune. Well worth the money & time. Great alternative to more expensive tuners. Will work on any Harley Davidson 36 pin Delphi ECM. Tuning accessories available to tune yourself. 2002 Softail Deuce EFI

I ordered the daytona twin tech 2 not realizing I couldn't use it. I already have a power vision 4 on my bike.

Super easy to install with great instructions. Cleared up all the issues I had with my 2005 Road King after my 103 inch upgrade to my twin cam. Running like a dream. Parts Giant has the right parts for the right price.

And exhaust seems like its 20% louder than it was before. Baffles were out then also.
In a word, yes - this will certainly solve your problem. Making the myriad of changes you've listed will cause a bike to fall on its face when you ask for power. This tuner, properly configured, will not only solve that miss, but also, give you better throttle response and more power throughout the RPM range. Plus, if you make any other engine or exhaust changes in the future, it's more than up to the task of handling those modifications as well. It's a really nice tuner.

I have a 2 into one and a S &S Breather on a stock engine will this help lean it out ? I get a lot of pops on decel or off throttle at speed. also plugs are a bit black seems rich 2002 Electra glide TC 88 FI
It might help, properly configured of course, but before you go down this road, have you checked that everything on your engine is sealed up? Specifically, make sure that the air cleaner, manifold and all exhaust gaskets are in good shape. If there's any chance of air getting in through those areas, you're more likely to encounter backfiring as fresh air leaks into the engine from various places. Considering the age of your bike, an old gasket might be the real culprit!

Will this work with my bike using Vance and Hines staggered long exhaust and does it have options on exhaust types
Yes, this would be a very useful tuner to work with your bike's particular set, and especially, as it evolves over time.

I'm not sure what your definition of fooler happens to be, so I can't comment on that. I can tell you that this particular device plugs in-between components such as the ECU/fuel injector(s), ignition &etc. (which, exactly, depends on what bike you have) and modifies the incoming or outgoing signal to enhance engine performance. The Power Commander works in much the same way. Other than that, pretty much every fuel tuner on the market works in this way. There are those that flash/reprogram new settings over to the ECU or completely replace said ECU, The Vance & Hines Fuelpak FP4 is an example of the former, while the Thunder Heart ThunderMax ECM with Integral Auto Tune System. Back to the Twin Tuner in question, this device - when configured correctly, has been proven to be an effective fuel tuner for a wide range of applications: aftermarket exhausts, air intakes and cams are well within the purview of this tuner.
