Re: LS1 - Flash - Reprogramming

["Walter Sherwin" <wsherwin@home.com>]

Funny you ask.  Just this morning I read a little blurb in GMHTP about Ken
Kelly.  He purportedly has an array of LT1 editors/programmers, and hints at
others, including LS1 coverage, soon to be available.  Says he can be
reached at 1-973-540-9252, or PCMdoc@surfree.com, or look at
http://carputing.com .  I know nothing about this guy or his products, just
thought it sounded to match what you were looking for......
