Prova ECU!
Hi All,
So managed to pick up a v1/v2 Prova ECU for my 1993 WRX. Wondered if anyone has ran one of these before?
I believe they are basically a chipped ECU with Higher boost and Advanced Timing and maybe improved fueling?
It will be a while before I fit this to my car as I need to improve fueling and cooling before running the risk of advanced timing. I also need to match the JDM fuel RON as I hear our normal 95 or E10 will just grenade the engine.
Also I wonder if you can remap the chip?
Im currently running walbro 255, decat, filter and Z4 ECU. Oh and ARP headstuds 11mm !
