[QUOTE="cipan_supercas, post: 1437094, member: 1945"] There're nothing wrong with your existing map sensor as long as you are not into boost. The original ecu that came with your car was mapped for n/a application. This means, when you are into boost, there are no more table to access, hence the check engine lit up. Solving the problem: I suggest you to install a check valve to the existing map sensor so that the boost will not be sense by the map sensor. However you have to install another map sensor that's capable to read boost for the e-manage. eg: greddy or haltech map sensor will do the job. Bigger injector have to be installed for this boost application. You can even use 700 cc Sard injector. You can then use the blue e-manage to compensate the injector size and mapped your boost application. To me, I'll just mapped the existing ecu and eliminate the use of those piggybacks. Good luck with your experiment. [/QUOTE]
