I'm new to tuning fuel and had some Q's about running an emanage blue.
1) First question, about hardware, from what I gather you cant just use a usb male to usb male and you actually have to purchase Greddy's "special" support tool? Plus a serial to usb adapter if your laptop is not equipped.
2) Is the map sensor necessary to tuning? This is running on a 1jz, but I don't know how this map sensor plays into the tuning? I doubt it would turn the maps into like 3 dimensions based on RPM, TPS, and MAP, but what does it actually affect? I am using a ZT2 for all my datalogging, so if it for those purposes, i could do without.
3) Now for tuning on the unit, I haven't got it to connect with the laptop yet so I havent experimented with the 16x16 airflow/map map. Is this to fine tune the adjustments on the knobs on the unit? So is there general rules like you use the knobs on the unit for pulling fuel? injector duty cycle for adding? Will adding fuel via altering map signal cause fuel cut sooner and pulling fuel via map signal cause it later or potentially not at all?
4) Can you explain to me which functions will work in open loop and which in closed? I was under the impression all changes occurred only in open loop, but altering the map signal obviously was changing my AFRs at idle bringing them from 12.7ish to 14.7ish.
Thanks for any advice. I'm sure I'll have even more questions for you guys very soon.
