Wound having my current ECU reflashed by Upsolute void my warranty?
If I purchased a new "stock" ECU unit to replace my "flashed" unit, before I take it into the dealer for service, wouldn't the dealer still be able to tell that I "was" using a flashed unit previously, simply by downloading my cars "history" from it's own "black box"?
Can I expect something close to a 1/2 sec. improvement in 1/4 mile ETs by spending $400 to $600 on the Upsolute reflashing process?
I know all these questions have probably been asked and answered before, but I'd appreciate some straight answers that would save me alot of time "surfing" the forum. Thanks alot guys.
