The best way to go hands down for the big power number is the Thundermax ECM replacement. A wide band, self adjusting and infinitely adjustable replacement for the stock ECM. This ECM will self adjust after the base setting is installed will self adjust for any future performance change (cams, exhaust, ect.). I am told it will be available around the first of the year for the new electric throttle or "TBW" application. A stock narrow band ECM is simply a manual box compaired to a wide band ECM that tunes itself for weather and altitude as you ride. I have knowlege of 118hp and 123Ft LBS out of a 110 at or local dealer with the Thundermax ECM (throttle cables). The company has a list you can get on for the new release.

Very interesting option. It probably would be the best bet for guys that are changing their engine configurations often. The biggest issue I personally see with this is that it would nuke Digital Tech that the dealers use for service. They plug into the ECM to do everything. The ECM module is also the interface to the security system control (e.g. auto arm, FOB replacements, ignition disable, etc). Removing the ECM completely would likely cause warranty and other issues.

Try that out , and if you have a problem in B.F.E. and they say, what's this???? We aren't touching it, it's not HD and you can't get a hold of Zipper's...Greg

I used the T max for a few months last year. Never could get the bike to run well and the mileage was chit. Zippers customer service (another oxymoron) is non existent. Pulled the T max off, replaced it with a Power Commander and life had been good!
For an objective opinion, ask Mr. Twolanerider for his thoughts.... :2vrolijk_21:

The DELPHI ECU is way ahead of the replacement ECU's in capability and functionality. The replacement ECU's on the market(except S&S) do not take advantage of the Ion sensing system that the Delphi uses. This is a great feature for excursions in fuel quality or those rare occasions when the motor might be "lugged". The Ion Sensing and Spark Knock capability will remove timing in these occasional excursions so that detonation will not harm the motor. I use the Ion Sensing capability when tuning to get the motor to the highest efficiency then the Spark Knock capability is there for insurance. The Delphi system uses Manifold Air Pressure for one of the parameters of adjustment which will allow the ECU to adjust over a wider range of riding conditions. Any of the systems out there that program the Delphi system directly are the way to go so you do not go backwards in capability. The replacement ECU's will tune fuel correctly but have no way of making any adjustments if the motor is pinging. My experience has shown me that a professionally tuned Delphi ECU on a Harley will have better overall driveability, performance and rideability compared to the replacement ECU's. I have pulled several replacement ECU's off this year and gone back to the OEM Delphi system and a tuner that programs the Delphi system. Some people might consider Dyno tuning the Delphi ECU a disadvantage, well if the tuning is done correctly then the bike will perform better than it ever has. Dyno tuning is a 3-6 hour job done correctly. I have seen where it takes hundreds of miles of riding to tune in the AFR's on a replacement ECU. Even after getting the AFR's auto-tuned correctly they are not correct for 100% of the area the ECU will have to go like anything above 70% or 80% throttle. Some of the Autotune systems also have trouble dealing with idle area and the deceleration areas. It still is a personal choice on what you do with your $30K motorcycle and if you like to tinker and change things frequently (air flow through the motor) then a replacement ECU might be for you. If you want to do some upgrades and just want to hit the button and ride anywhere in the country the Delphi ECU with a tuner that programs the Delphi ECU is the way to go.

Couldn't agree more... :2vrolijk_21: Especially if the goal is to just get on and ride!

Now that I am getting some great in put and my opinion is changing. This is an excellent place to test what you are fed by the experts. Thanks and keep it comming!

I completely agree with the first post that the Thundermax ECM and the company behind it are outstanding, responsible, respectful, effective and indeed penultimate products and vendors. But I'm also stoned higher than Sarah Palin's hairdo :bananarock: :drink: .
The Thundermax has promise. Have always conceded that. But it's far (far far far far far [far far far]) from bullet proof. The company's canned maps used to start are too often not accurate. There are almost no tuners around the country to dail them in. The "autotuning" function too often makes poor choices rather than good ones. And may god help you if you need support from the vendor after the fact. Crap shoot at best.
Do you really want to be three days out and some untold hundreds of miles from home with a non-OE ignition system that almost no one besides the vendor knows and have the rest of your trip dependent on a crap shoot?

No doubt man. Readin' my mind. Anyway, isn't it one of those guy-sins to knowinly allow someone else to get caught in their Zippers :nixweiss: ?

This post has saved me from untold expense and aggravation. I can't thank you enough for the excellent advise!
