Re: Eec-iv A9l = C3w1
There are some differences to the A/F and spark tables. In short, the C3W1 has richer base fuel values but a less WOT fuel fuel multiplier so it works out to almost the same. The C3W1 is commanding about 5.5-degrees more spark at WOT throttle than the A9L so that might be the cause of the pinging. You'd need a custom tune to change these things. Have you tried running premium fuel?
