Sounds to me like LRP burns faster, if so would require less timing advance. What octance is LRP? 95RON? So much for it being a Lead Replacement Petrol if you need to tune your car to run it! You probably don't have enough compression to make it ping and because of the faster burn rate detonation would be less likely anyway. Has anyone experienced pinging running LRP vs Leaded with the same ignition timing?
