BUT the difference with the Emanage is it starts you with a nice basemap and alters the maps for you after you enter what injectors you are using, then from there simple tuning is all you need(only took us 3 runs last night for a nice ~flat AF) its more like an "advanced piggyback"

timing control...you'll have retard the timing to a set point and thats it via the CPS. on the other hand the Zem(or chipped ECU) should allow to to retard degrees per pound of boost across the entire range...which is more efficient(and easy to tune) cause in vaccum, timing will remain stock, but ONLY begin to retard in boost thus the car will not be a slug when driving in vacuum(which will happen if you retard to much at the CPS).

lastly IMO FMUs suck ....anything that FORCES the injectors beyond their means by simply skyrocketing the pressure according to boost is scary. yes they are proven to work, but can eventually lead to leaks and burnt out injectors


for you all Emanage(least $), JWT(a little more $), Zem($$$$)...IMO ZEM is the best choice if you're going BIG(full ECU control and map editing), but so far my experience with Emanage puts it in the running as well for a nice entry level "advanced" piggyback that will control both fuel and timing aspects
