Thundermax
he had the ThunderMax ECM on display and it replaces the stock ECM.....most ECM's in autos are flashable so I see no reason the ThunderMax is not flashable........the stock ECM is flashable but the problem is the downloads from Harley are to generic and not custom maps for your particular set up......also it was Zippers located in Elkridge MD and from what I have found out they have a solid reputation....
The SERT/PCIII is what you need, not a new ECM.
if not, the software is very user friendly and allows you to adjust all parameters.
why would you want a new ecm?????? ask that question when your factory ecm fails while flashing with sert, if thundermax were to fail, you still have the stock one to get you off the highway, or even home, depending on mods.
zippers does not sell junk, nor do they participate in scams-------maybe you should do a little research before making those kind of accusations.
there are four tunes today, sert, thundermax, dtt, and the new closed loop s&s. sert is the only one that does not give you a new ecm!!!!
Correct Above. So back to my original..sounds like crap. Why would you replace the ECM when you can do everything with the SERT. There is nothing wrong with the stock ECM. If the guy is selling aftermarket ECM's then it sounds like he's trying to sell you a scam.

The Thundermax is a bit different than the SERT in that it has more touch points to tune at than the SERT. You can get much more tunability out of it, the processor inside it, is faster and has to be to allow you the number of cells it does to tune the bike. The initial maps given by Zippers continue to grow and they are offering them to you at no additional charge as well there is supposed to be a web site coming soon where you can go and just download them. To say the item is crap is just ignorance. While some won't go through the expense to get one, others will to get more tunability out of it. To give an example my buddy has an 03 SERK (screaming eagle road king) The bike could have been tuned more than the base map, but he chose to leave the bike where it was on a stock 103 with bassani true duals and a HD SE A/C ended up at 105 tq / 95 hp. He exceeded my bikes base numbers which were 98 tq / 94 hp with D&D's 2 into 1 and SE A/C and SERT.
