Quote from: Prof;523702Generally you\'d expect a nice curve - starting rich at idle, gradualy going towards 14-14.7 in the low to mid RPM\'s then after 3800, .

On "boost" at peak torque 14.7 afr is too lean, needs to be at least 12 afr at anything below 10 psi.

You should only see 14.7 afr when you are cruising

My bad :spank - just realised his boost comes on max quite low down - so yeah - he\'s getting quite high AFR\'s for 14 psi.

For \'quite high\' I would read \'rebuild waiting to happen\'. 14:1 anywhere but on cruise on a turbo charged rotary is asking for apex seals to leave rotor housings at their earliest opportunity.
