yeh...you read it well....I had the wrong premix ratio. major problem with my detonation! I called enemalta today which is our fuel provider, they say RON for Unleaded gas =95 Lead Replacement Petrol is 97.5....I doubt they are credible!!!any idea for stock injectors(550/850) and ignition timing on those ratings??(perhaps I BLOW my engine if they are incorrect!!)

95 RON = 91 pump octane
97.5 RON = 93 pump octane

If your RON ratings are correct, than Chris' timing map should work, and probably even my 91 Octane map.

Do you have a FMIC? My 91 Octane map assumes FMIC (cooler intake charge than your stock SMIC, I'm sure). Your current timing map is a lot less aggressive than mine, so you should be fine....
