instead of copying our turbosystems steve 4i chip and pasting in tables from old yb chips you should have left the trick ignition table and map alone
you have lost the 3.10 absolute pressure break line and replace it with a 2.82 absolute point
the line you lost contained lower ignition values
Whilst your over all afr values may have been correct at the time on the rollers and you may well have heard no det you could well have been mapping the tables at the wrong points due to the weber l8 being speed density
this is why it detted
Stu already has your 2.82 bar absolute ignition pressure line
surely it is for you to explain why at any pressure above 2.87 bar absolute why the ignition line you wrote doesn't alter
if you thing 14.00 degrees of advance at 45000rpm is fine at 3.4 bar absolute on a yb on pump fuel please explain your thinking
the map point below is 14.25 degrees the point above is 13.5 degrees
