....I have used my JWT ECU since 1994. I ran low 12's in 1996 with it, ran the Pony Express in 2001 with an average speed of 130, and ran the Pony in 2003 with an average speed of 150 over a distance of 85 miles. I have driven the absolute crap out of that thing, in about as wide of a range of conditions as possible, and I have never had a failure related to engine tuning.
I AM NOT CRITICIZING ASH'S ECU, but I don't really see how it can be proven that it is more reliable.
