Got the car back and am setting it up to run on standard ECU (a long story........). Got fault code 13 - oxygen sensor. I think its running a bit rich. What could that cause this fault, or is the lambda sensor knackered? Fault only came up at WOT and boost was too high at that point too (trimmed back in standard range now as also got fault code 116 - boost too high). What should the standard fuel pressure be, is it 3.5 Bar i.e. 51psi? If so, my fuel pressure gauge (when the vac connection is off the FPR) should read 51psi at idle shouldn't it, at present its showing 62psi and the AFR is showing 2 greens on WOT.
