eamiller Posted September 26, 2005 Share Posted September 26, 2005 So, tomorrow my ECU should FINALLY be replaced for the cooling fan issue. I have a november build, so I should have the pre-studder fix ECU. I'm just curious as to whether there are any external markings differentiating a pre-studder to a post-studder ECU (i.e. rev A vs. rev B). I want to make sure they are installing the latest and greatest. Also, I don't currently have a big issue with my studdering. Although, I do notice an occasional lack of power, presumably from the ECU pulling timing. Link to comment Share on other sites More sharing options...
Brady Posted September 27, 2005 Share Posted September 27, 2005 I'll give you a hint - the pre-stutter ecu behaves identically to the post-stutter ecu. Link to comment Share on other sites More sharing options...
legacy2005 Posted September 27, 2005 Share Posted September 27, 2005 i never really noticed a studder in mine. but then again i only had the "stock" ecu for 1k. i reflashed to stage 1 at about 1100ish. havent had the cooling fan issue pop up yet, and hopefully i dont any time soon since ill be going stage 2 soon (as soon as Jeremy gets off his butt and releases the midpipes for the lgt..lol ) at which point dealership work is out of the question. Work hard. Play even harder. My Garage Link to comment Share on other sites More sharing options...
eamiller Posted September 27, 2005 Author Share Posted September 27, 2005 A reflash won't affect the lowside transistor that is shorting out in the ECU.. If you go stage 2, they should still replace the ECU if your fans are on all the time. It's a known problem with the design. Link to comment Share on other sites More sharing options...
