Replying to: bill2007yukon (Aug 14, 2008 10:02 am) Has anyone hd any experience in getting the ECU reprogrammed so as to make the engine stay in V-4 mode more often? With our 2007 Yukon, we NEVER get on it and pretty much just baby it around town so as to get better gas mileage so I think this rig could stay in V-4 pretty much all day. So what is the logic that the ECU uses that tells the engine to go from V4 to V8 and back? I am working with Jason Gadberry at Blackbear Performance and he is really sharp...and he thinks he can crack the code. So has anyone actually got this done to their truck? What kind fuel mileage of performance did you get? Any pit falls of things to avoid? **End Quote** I would suggest using cruise control as much as possible. I notice on my Tahoe, if I'm just driving I will rarely see V4, but with cruise control I'm in V4 a lot more.
