I hate not having open source for my car... There is a rumor going around that a few of the guys that did a lot of work for the evos open source have been working on the G and Z's, but i have not heard to much at this point.

 

isn't osiris pretty much open source? you have full control of the stock ecu...

 

osirus and the haltech are about the only things worth running. i havn't checked up on updates for awhile on either of them though. osirus looked promising from a cost stand point, but haltech had more options suitable for high hp f/i. awesome interface also!

 

Osiris is not open source. Something like Ecuflash is opensource since its free and you are able to modify the code and make changes. Their are no license restrictions. AEM, Haltech, Osiris is all software that is license protected and you pay for which is not opensource.
