I'm still seriously contemplating this even after my JWT ECU (Tuned for Z32 MAF and 50lb. injectors....) To help lean out the spots that JWT tends to richen up for saftey purposes.......I also like the rpm band adjustment on the E-manage vs the SAFC2 It seems to be a lot more accurate not to mention the signal will probably not be lost from the e-mange to the ECU as easy as it is from the SAFC2 to the ECU........

IMO this is the way to go if your not going to go stand alone, or you allready have a laptop that will support this with software....Otherwise if your buying the E0-1 and the entire system (blue box, injector, and ignition harness) your prolly wastin your money.....A decent stand alone can be had for about the same price........Emanage full system is about 1100$.......A decent standalone can be had for like 1400$
