MAC11 update

I'm with Louis-Alain, I think the coil is the next place to look.  
Think of it this way - if the flywheel was damaged it's not like the  
damage would dissapear at low RPM so why would it run correctly then?  
If the pin was off the timing would NEVER be right, unless the pin is  
switching it's position in the flywheel in real time ;-).

Here's another data point - the tach is run off the ECU. If there is a  
problem in the ignition related inputs (flywheel sensors) the tach  
would go haywire or stop working all together. If the tach seems like  
it's indicating correctly then the issue is an output problem, not an  
input problem. It's entirely possible that the igition coil is failing  
and just can't produce a big enough bang when the frequency demand  
increases. Rick, whats the chances of you (or a buddy) having an  
occiloscope?


Oh and I like this "... gotta love the supportive way folks operate on  
the "quattro list" these
days ... " by Steve B. Not only does he write that about Huw's post,  
but he completely neglected to read Ricks post and asked Rick to test  
exactly what he spent time detailing out about what he did last night.  
Good stuff.
