the ecu is pre-configured, with two maps, sea-level and 5000+ft and not changeable, it is optimized to 2012 m8 with push turbo and 2 elevations.
there will be a ecu for 2008 - 2011 (push, BD, cuttler,...) but in that case you have to contact jeff from dakota performance to talk about the setup.
egt is a nice way to control the 2 stroke engine, very effective. 02 sensor is also a good way but very problematic on 2 stroke, readings are not working all the time and the ecu can't use it to adjust it self.
the hp output is the "max possible "save" hp output" there are always people who want more and more hp, but there is a good match between power/reliability an this is the line where push is walking with his product.
the OEM dash sucks, you pay 15k for a snowmobilie and you get a dash with 5 functions? rpm, speed? (who care about speed on M series?) temp, trip, ...
IMHO that is a joke. The new dash is available mid- end october ans is plug n play replacement of the OEM ACat dash. but with all necessary informations. Honestly, who is watching his dash all the time? i take a look to rpm, egt, and maybe sometimes to water temp. that's all.
Throttle body before turbo, is definitely thinking out of the box, there is no other way "technically" to have a quick response 2 troke with a turbo, and we all know what you need when you do side-hilling, boondocking and all those burand/rasmussen style stuff. you need quick response. Also, We all know those problems with fuel/leaning out engine/ stock injectors, ..... nearly all those problems are solved,
finally it is time to make a step forward,
