Re: Mac-01 vs. Mac-02

     Paul,
     I'm not quite sure I follow your argument here:-

     RDH's modified EPROM is a very easy and reliable way of increasing the 
     performance of a North American ur-q. By mounting an IC socket in the 
     MAC02 it is very easy to try many different EPROM programs and revert 
     to the original. 
     
     "Totally unstreetable"? your modification does not allow the duty 
     cycle of the frequency valve to be modified for a more aggressive cam 
     (e.g. a Shrick 272). This can only be done by reprogramming the ECU 
     and supplying more fuel for a steadier idle. Allowing the ur-q I5 to 
     reach red line in the same phase of the moon hardly makes it 
     unstreetable.
     
     Once the assembly code is understood, reprogramming the EPROM offers 
     many more tuning possibilities than the Schrapnel Knobben. I agree 
     this is not what most people are looking for, but don't write it off..
     
     I respect your work (hey, I bought a Schrapnel Knobben) but personally 
     I prefer the EPROM mod.
