There are hundreds of posts here on oil temps, engine heat, blah, blah, blah. Having said all that, you are 100% more likely to have engine problems due to poor manufacturing practices, inferior parts, and poor assembly than from changing the exhaust system and either a canned map or Dyno tune from a COMPETENT tuner. Again, I'm not saying Fullsac and TTS is the Buddha/Nirvana of all systems, just that it works. The "canned" map provided by Fullsac for the TTS is not just something that's a "best guess".many, many hours have been spent on a Dyno perfecting the map you get with their exhaust system, and IMO, it's pretty damn close to perfect. In addition, the TTS allows you to upload your stock map from the ECM BEFORE any other changes are made, so you've always got that to fall back on.other tuners may allow that as well, but the one I know will do so is the TTS. With a device like the TTS, SEPRT, PV, Direct Link, etc, it would be more difficult for them to deny warranty coverage, particularly if all you've done is change the exhaust system and load a new map, whether a canned map or one from a Dyno tune. However, the odds are just about 100% that if you take your bike into a dealer and have a Tmax installed, and your engine has some real issues, the MOCO will definitely try to blame it on the Tmax, as you have replaced the entire operating system (in essence) for engine management. A lot is dependent on which dealer you take the bike to if there are serious engine problems. Just to clear things up a bit.ANY changes to the ECM can technically void the warranty. That 120r is tuned to run quite a bit of closed loop, too. I see hardly ever see any 300* Head temps. TTS, SEPST, Direct Link, etc are tools to flash the DELPHI ECM, nothing more.ĪNd to the other dude. There is no way in Heck, I would swap out a DBW Delphi ECM for a TMax. your 'indy' doesn't have a Dyno, I bet, doesn't know how to tune, and a TMax USED to be a way out for guys like this. it is going back to Thunderheart at some point. as stated by Zippers at the last Cinci Expo. Zippers no longer messes with a TMax either. TMax cannot tell if it is uphill or down hill, etc. That is IT! No map signal for loading of the engine. TMax does not even use a MAP sensor so it has NO idea of how much load is on the engine. TMax allows you to build a new map out of what has been seen by the TMax, it is NOT instantaneous. the Delphi with ION sensing pulls timing when the engine gets crap gas or starts to ping. The TMax is Alphi N and the Delphi is Speed density. The Delphi is a whole nother generation above the TMax. Dude, that Tmax sucks compared to the Delphi for sure. So, the PROPER comparison should be Tmax-vs-Delphi. Just go to You tube and put in Thundermax.Ī long post i know but you wanted some info.TTS is not an ECM, like that Tmax is. I'm happy with mine.My bike is running really well and my fuel consumption hovers around 44-45 mpg.However,i dont ride hard and all my work is roughly between 2200-3000 rpm.įurthermore,there are a number a great 'How-To' videos on physically installing the T/max and on how to actually Load a map. It works by having a particular engine base map loaded into the ECU.This map is a reflection of any mods or alterations that you have done to your bike.There is a considerable number of base maps available to you on the software that comes with the T/max,and even if there is NO DIRECT (100%) match,there will be one that is pretty close.The beauty of the autotune function means that the system will overcome any disparities and eventually tune itself to match.Also,this process means that no Dyno time is needed to tune.You can either load a base yourself,or you specify your criteria and the shop you buy it from can probably load it for you. I run a T/max with autotune in my 2008 FLSTN.As mentioned,the T/max is a direct replacement for the H-D ECU,and in the autotune mode,it comes with wide band Oxygen sensors that replace the narrow band H-D items.Basically,you remove the stock ECU,Oxygen sensors and associated wiring and replace those with the Thundermax bits.Pretty easy overall,although i found Zippers to be a little parsimonious with the front wiring harness.A couple of inches short of a good length.
