Yes! See my Mileage Log below. April was when I got the SG. Immediate 10% jump, just from seeing what works and having instant feedback. Further refining of technique brings me up to over 30% improvement now.
I've saved $200 in gas since then, easily paying for the unit itself. In my opinion, it's THE BEST upgrade you can do for fuel economy.
When it displays SES codes, how are they displayed? In detail, or just the code?
I'd rather it be able to tell me why the SES light is on than tell me a code like "P1449" or something, then I have to get on the internet and try to decode that or bother everyone else finding out....
Well, nothing will tell you exactly what's wrong. Fault codes are just what they are. Yeah, somethings are specific like a faulty sensor, etc., but other items come from combinations of items that require that each item be checked or be sent through a series of checks. Might be three items that control a specific set of parameters, but only one of those items is failing.
I'm not sure if that makes sense to you, but that's the way it is. Think of the code as a clue on where to look. Sometimes, it points to one item. Other times, it points to an area.
Say you have a misfire in cyl. #3, does it tell you, Misfire: Cylinder 3.
I recently had SES Lights on and had to (once again) make a trip to see a friend w/ an Actron scan tool to find out why the SES came on. Luckily, his tool tells you what is wrong, other than say "P1440". Get what I mean?
