Stock AF ratio is 9.7:1 @6500 rpm (blarf)
CP-E moves the AF to nicer 12.5:1 to 13.5:1 depending on rpm range. It also richens the fuel mixture earlier in the rpm range (around 3000 rpm vs the stock 4500). Its not a "blackbox chip" ...nothing like you see on ebay. Its a complicated circuit system which primary function corrects the MAF signal allowing you to run non stock specification piping (which normally throws a cel on all mazda6's), while maintaining a proper 14.7:1 ratio in closed fuel loop modes. (Openloop in 85% Throttle Position or 4500 rpm+)
I think your confusing this system with those 20 dollar IAT chips on ebay =/. Those just generally adjust the overall curve (generally richen the A/F mixture) and throw all manner of check engine lights. The CP-E
a) Corrects the MAF signal in closed loop modes, preventing the fuel trim from going lean at idle or in closed loop, preventing P0171 and P0174 Cel's, as well as preventing the injen intake pings.
b) Adjusts the A/F ratio (richens earlier and leans later) from the horribly sick sub 10:1 ratio, to a more normal power making 13:1...this also stops the fuel dilution issues, excessive carboning, and the cat's from being doused in gas.
As I said earlier, CP-E is looking for MSP's to possibly work on a system. If you know anyone interested in prototyping, send the contact info to them.
Here's a FAQ on how the system works.

The dyno's are by club members, not some random manufacturer test. You actually pm the vehicles dyno'd if you want. The first injen/cpe dyno was performed by myself. (I ran the dyno, and did the logging). The second was 5sdoors on 6tech/6club.
How do you like the AEM EMS? We've had so much trouble with it on the 3000GT...damn AEM keeps saying its not their fault, then secretly changing settings in the revisions . Around 400 AWHP now on pump gas though .
