Re: MB/1B engine questions

Phil,

This is an old thread-reply of yours from just over 1 year ago.  In cleaning
up my own archives, I find this interesting as currently I'm running an ECU
with an EPROM Peter Link at MTM made for my car (EPROM only, no other
changes).  I get max. boost of 0.69 bar now (digital manometer, accurate)
like clockwork.  The EPROM will be joined by a change to the boost sensor in
the form of a resistance to the output and an optimizing WG spring pressure
for the changes while avoiding our friend pre-ignition/detonation.  All
changes are done step by step with thorough on the road testing with two
sets of ears in stethoscopes leading to the valued new head whilst driving.

I've put my faith in MTM (or actually Link) after much deliberation.  I'm
looking for a modest increase in power, but more than that, already even
with the boost sensor still unmodified and stock spring pressure, the car
runs much stronger with better mid-range torque with only fuel/ignition
remapping.
