This is a late 4G93T. Correct?
Unless that engine was offered in other markets to run on different grades of fuel looks like you are down to keeping it topped up with octane boost. Do not know if someone back home has the gear and knows what calibration maps to access.
I know first hand that OEMs spend millions setting up and testing engines to work in dfferent climates. So if this is a JDM only car then Mitsubishi would have not have cal'd that engine to work on crap fuel (trini). Hence the spark maps would be well optimised (within MBT, minimum best timing and/or det limit) for better fuel. On the fuel side they would have mapped that motor on the principle lean best torque (LBT) for all three modes of operation. Then one should also consider that your base maps are one thing but the output that comes to the coil pack/injector is based on multiple optimisers working on the base map. Each manufacturer has a stratigy to implement this. Even though the knock sensor will pull spark out under certain contions this is calibrated to work at certain frequencies (knock window). If you fuel quality is poor your det threshold will be lowered well before MBT in some cases and you will knock even if the max spark is being pulled by the KNK sensor. In the service side if your air mass meter is dirty this could trigger a "Bank 1 lean " fault and can cause this problem. Anyway I said enough. Hope you get it sorted.
since blow by reduces octane levels, would an oil catch can help?
its cheap, and it MAY work
HODDIE....The AFC i am talking about is from APEXi...and it can add/remove fuel +/-50%...at 1000 rev increments...if what you are saying is correct I will try this...thanks
Either way... Hoddie... our ''95 octane'' gas is 95 RON, which figures down to just under 91 octane at the pump.... it's about equivalent to what you get at your gas stations that would be called regular.
And Forth you sould not install a SAFC on this car the timming will be altered way too high Karmon Vortex meters don't react like Hotwire, Flap MAF's or even maps.
