Hi there people just joined the site so hello ! I
I have just bought a r33 1995 and it runs well no bad idle etc I'm pushing out 347bhp and some times the car will cut out on full lock if you brake hard but only a couple of times ! on the dyno its in the lean zone just under 13 and hits just over 13 in places ! my apexi power fc is detecting knock ! it hits 60 and the engine light flashes .
The tunner I took it to says it needs a full map ! but the guy I bought it of had it mapped in November and I rang them and they gave me the figures over the phone and the car was running as it should . so my question is could it be the afm ? it just had a fuel pressure test and all was good so I guess that rules the fuel pump out and fuel filter etc ?
I run high octane fuel any help would be great thanks
