Fuel Knock Test using octane booster

Got another test done today from a specialist got my car hooked up to a reader to read Knock, Fueling and Emissions again well happy with the results run mine with 95ron unleaded no super here and Lucas Octane booster mixing it to 47litres on first tank with one bottle of Lucas and then before reserve light comes on then fill up again to 47litres in the tank, one Lucas treats 25gallons -94litres lucas octane booster octane rating when I got test done drove car low down in revs first little knocking and as soon as it did knock as all engines knock the Ecu corrected it, it knocked round 2500rpm-3000rpm and then never knocked after that thank god all the way on boost it was well with-in limits. Emissons were a bit high as she getting a bit too much fuel but mapper thinks fuel pump uprated and the cause of this but I didnt even see the pump thats in it yet but all in all going by this engine running 100% with fuel and booster not a lean mixture causing damaging detonation due to low octane rating. Roll on the mapping for 95ron soon dont need to be mixing it with octane booster any more good to know that this octane booster works and my car for people that dont know is running standard boost at 1.1 bar and just has K&N panel filter and Ninja backbox all standard apart from that but maybe if my car was tuned it might aswell knock more cause octane booster might not cope with fuelling right with a more powerfull engine, but in standard form all great really.........................
