I fitted a Haltech E8 to a friends 4x4...wee buns ( relatively speaking of course ), and ya dont need to cock about changing sensors or triggers.

Its quite tame for now but that will change.

The L8 may be very good for some....

But when mere mortals like us cant easily re-map it, its more like a useless box sitting there.
I was quite glad to throw it in the corner.

Depends what each person wants to do with their car, and who is tuning it. Everybody has their own preferences.
