1989 Turbo II Mazda Rx7
#20
I guess i'll post an update because I just remembered my forum password.

Since April I have installed an adaptronic PNP s5 Ecu. Now I can actually monitor temps and adjust timing and fuel tables. I installed a AEM wideband so I can keep those AFRs super rich. I installed a corksport aluminum radiator which has proved more trouble than I think its worth. I also got my turbo rebuilt because my dumb self left the filter off and it ate a loose wire connector. Currently I have the car running hella rich just to avoid any real damage. I am slowly leaning the map out where it needs it. My biggest problem is overheating. I have been chasing small coolant leaks after I installed the new radiator however at 70mph + cruising on the highway temps like to climb up. Idling the car has no problem and anything under 60mph the cooling capacity is fine. That's what has me puzzled its not a rpm dependent property it is a speed thing. Maybe my ducting is all messed up or something else is going on. Anyhow the car still runs which is nice.
