A little birdie told me that the winter fuel and colder air temps have been a real pain for LMS. But, they think they've got it and just need a few more days.
Winter fuel has nothing to do with the fuel pressure drop. I ran 104 octane race fuel with the 91v2 and hboost and the 93 v2 and hboost and they all dropped pressure at 4500 rpm. Winter fuel is their go to excuse but it is a false excuse.
I wouldn't be surprised at all that the fueling is going a bit lean and dropping, but everything I've discussed, but can't pass on, pretty much points to that not being the actual issue with the surging at ~4500-5500. It has to do with how the tables in the tune interact and how you'd normally tune just about any other car causes an issue in our computers.
I've tuned my own vehicle before but never seen the tables/layout of the explorer so this is all conjecture though.
Since our update came out a bit over a month ago I haven't had a single issue down to ~17 which is the lowest we've seen. Still haven't seen an update for the SS tune, but I think thats been put on the back burner for awhile since they are going to move it over to a 3 bar setup.
May have to make a move on the tuner if livernois doesn't get it fixed before too long.
First, please understand that this post is not meant as a flame or a dis of any vendor or member.
I'm doing homework too. Planning, among other things, a tune in Jan. One point on the unleashed tunes is that they are capable of data logging without other hardware (because of using an SCT tuner device) and this can be sent to get an individual update for your specific vehicle from unleashed.
Livernois doesn't offer SCT for 2013 and up SHOs and has been working the current problems sited both generically and specifically in this forum on multiple threads for some time and it remains unclear what is global to the engine/ECU platform of the SHO/3.5EB and what is specific to individual vehicles.
A lot of answers given to members seem (to me) to have been based on phone or email conversations rather than data logs. Is my thought a misconception?
