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. 2002 Softail Deuce EFI
