Once agian I run into a problem. The b16a with pr3 ecu uses 2 o2 sensors for cylinders 1/4 and 2/3. I have a DRAG cast iron manifold, where do i put the o2 sensors? Do i put them in the down pipe…In the manifold… Is there a way to just chip my ecu to use only 1 o2 sensor in my downpipe or somthing???
chips your ECU. talk with xenocron about it.
does he chip pr3 ecus with a turbo base map also?
Use BRE as the tunnig and disable secondary O2
where can i get bre and can i chip my pr3 with it
