Re: [ST] FI Tunes and Coolant Temperature

I thought I had posted the fact that last time I was in the dealers, a month
or so ago, with hot starting problems on the RS he had just received the
issue 10 for the tunes for the ST and RS with stock and aftermarket exhausts
but I can't trace it . He installed it and so far I've not had a repeat of
my starting problem. Sorry I can't remember the actual tune numbers but they
still start 10...
