I'll be installing mp, removing the airpump and adding the power fc here in the next day or so. My question is its just a base map that it came with and I'm guessing ill be needing to add some fuel to compensate for the mp. I already have intake, dp and catback....ive ported the wastegate and have a mbc. Does anyone have a good idea of how much fuel to start off with adding to the map?? I will be installing a FJO wideband at the same time it's off my old civic car, so im familiar with tuning just not the rotary and the power fc, used aem before. Just want a idea of where to start with fuel so I can be safe and save a little time. Thanks in advance for any help.

 

If the PFC comes with the base mod map (Intake, Downpipe, Hi-flow Cat, Catback, Intercooler) which most do then you will already be in the ballpark. With watching a WBO2 and slowly boosting you should be safe enough. You could add a little fuel above 3000 rpm if it would make you feel better. Turbocharged Rotaries should be no leaner than 11:1 AFR at 12 psi unless you really know what your doing . Make sure you have the base mod map by comparing here...

Alright cool thanks man. the base mod map is just supposed to be the negitive split right?

 

The split table is just the leading spark timing minus the trailing spark timing. If a value is negative in any cell of the RPM/Pressure map it is called negative split. This is very bad under boost but tolerable in vacuum. These ignition maps can be smoothed out if you like. Just compare all the base mod maps to what you have in your PFC. Here are some good rotary tuning docs...
