Hey guys I've got a 95 sc300 that i've turbo'd and would like to tune. It has a karmen vortex maf. My AEM FIC 8 has the ability to "clamp" my Maf voltage but it seems like my MAF runs off frequency as i was able to get the car to run when i altered the frequency map on the FIC but it wouldnt run just changing the voltage map.

Think i can eliminate the MAF and build a tune off the internal MAP sensor the AEM FIC has or should i make it happy with maf then fine tune with map?

I'm not really sure how to proceed

 

are you using the 2jzge ecu with this aem fic 8 combo? Tuning karman vortex is going to be a pita. Your wasting your time. Alot of people, use a tt ecu mod with these types of piggybaks. Im not a big fan of aem fic and havent used them. Mapecu3 is your best piggyback option imo. Use a tt ecu, with the me3 and turn that kvf to map frequency. That will give you alot better headstart, You are going to e pulling your hair if you are on a GE ecu with aem fic.
