I was wondering if there are any functions which our stock ECU handle which a standalone system such as Haltech or AEM EMS do not. Has anyone here been running the Haltech, and if so, are there any problems with guages needing adjustment, etc..?

Thanks.

 

your best bet would be to ask dave at RPW, as they specialize in that system. but i too would like to have some more info on the haltech as i am thinking about going with that setup.
