i am in America and most of the performance cars and V engines ( 6-8-10-12 cylinders). With the that being said the second bank is needed. With a dual bank engine it is nice to know if you have a problem with one of them and which one is having the problem. I have this set on the SHO twin turbo Ecoboost -- it is set up an EGT input. I noticed that one bank was running off. I lost an O2 sensor.

this was a huge discovery. Saved me many of hours of trouble shooting while tuning.
Also everyone i show your display loves it. The one picture is a little blurry.I have the buttons installed in the dash at arms distance and NO one sees it.
Also while we are talking about I own a small performance parts place. [url]townhaulperformance.com[/url] I think that is a great produce and i believe it can do great things over here. I have had it installed for about 2 months and have had nothing but praise about it.
So I understand your situation and hope you will consider the changes i mentioned. My full time job is in the steel industry programming industrial computers so i fully understand the "simple" change can be harder than others think. ( i also do automotive tuning with my business -- I try to get EVERYONE i do a tune for to add gauges. this unit is great because it does not make the car look like a "race-car" It can be hidden in the interior and no one will notice it until it starts up. Plus it is every gauge one would need rolled into a slim functional package)

Hope to hear form you soon
