Re: EPROMs & mods, etc.

I am 99% positive (only fools are positive  :) that the IA mod, at least Stage 
II, does alter the ignition timing. I was one of the first to upgrade to Stage 
II and Ned was very interested to find out if I had preignition problems 'cause 
he was concerned that the Stage II setup he gave me might have been too 
aggressive for pump fuel (it works GREAT!). Ned told me that a discreet 
resistor value is changed to alter retard as a function of boost.  He also told 
me that he would give me more info on what res values to use to get less/more 
aggressive timing and/or retard as a function of boost. Also, he said I could 
install a pot and make it infinitely adjustable. I plan to try this mod and 
perhaps drill a hole in the CPU case to allow adjsutment with the unit ins
talled, though I have never followed up with him to get the componenet location 
and value data. So, on Stage II anyhows, IA does improve the timing, but via a 
discreet res value change, and possibly within the EPROM as well, but I cannot 
confirm any EPROM changes yet.
