Actually, the Greddy emanage is much more versatile than 5 points. If you get the data cable(a chipped USB cable) and software, along with the injector harness, you can change the fuel maps. With the ignition harness, you can change the timing maps. Both can be tuned in 16x16 resolution.
MAP = Manifold Absolute Pressure
To eliminate the MAF, you would need to convert to a MAP sensor based system. The HKS VPC is a device that does this, but does not have a KA application, is discontinued from what I hear, and is expensive. for the price, you could pay a little more and get a standalone system, or if you want plug and play, you coulf go the JWT route.
240Girl, you would only need the JWT ECU for this since you already have 370 injectors. But I'm thinking you must already have some other way to compensate otherwise you'ld be running very rich. 370 injectors by themselves will allow you to boost to about 10-11 psi depending on the turbo, tuning and fuel octane rating(Some states have as high as 93 regularly available, in CA I have 91). If you have the FMU, you should be able to some more. But an FMU tends to run rich and can really suck up fuel. I'm getting about 15 mpg with only 7 psi of boost and only an FMU to add more fuel. The injectors fail wide open and it just dumps fuel until the higher RPM's lean it out.
