Customer Reviews
Recommend tuner
By James P. on
Verified Purchaser
Was very impressed with this less expensive little box. No more spark knock and I'm no longer running lean.
Great tuner for all 36 pin Delphi H-D ECMs
By Darrell W. on
Verified Purchaser
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.

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

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.

Questions & Answers
2006 Harley springer Efi
By Manuel M.
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.
Is this tuner what they consider a "fooler" or is it actually making the effective changes?
By Pops
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.
