I think the first one is the limit, and the second one is the actual value you would like. The idle limit is bit hard to work out - the first is set at 900 rpm and the second is set to 950.
The second limit is also set to 7500 rpm, this is the launch contol limit ( I set mine to 5500 rpm, ignition cut with full fuelling = huge flames ). When you look at the rev/idle menu, the first limit is set to 7500 rpm, this is the rev limit. I worked out some of the other settings ( manual is all in Japanese ).
It idles rough as anything for a minute at first but soon settles down as it learns. Basically this means run the car for 10mins with no electrics on, switch the rear demister on for the next 10 mins and for the last 10 mins switch the aircon on ( 30 mins altogether ). When you first start the car you are supposed to do a self-learning idle setup. If you dont then the car will start but will not run for more than a few seconds before conking out
Good bit of advice - If you dont have an Apexi boost controller ( you are using a Greddy or similar ) you will have to deselect the 'Apexi' option in the boost settings menu. Seems like quite a few people have got new shiny Power Fc's, so I thought I'd start a thread for anyone having problems with them ( like me ).
