The VRIs points are proabably the biggest gain from the ZE ECu, but the fuel maps may be slightly different. Either way I can see big gains from this setup.mysterextsi said:i thought the point of the vrtuner is to actually simulate the vris opening of the ze ecu? isnt the only function of the ze ecu is to have the right vris opening? i just sold my ze ecu/maf so that i can buy the vrtuner which is a lot cheaper than the ze ecu/maf. however, the car will be stock for winter so i wil buy it next spring.
