I'm sure all say that. Less than 1 week ago, Sylvain at PEFI told me theirs (deto/knock protection programming) was the first on the market in late 2016/early 2017 for the 998. He said theirs is still the most sensitive (some might say PEFI's is too sensitive as even chassis "noise" can trigger it) and the best. I took that to mean that it will protect the engine from damage if deto occurs.
Don't they all say this?!!
Yet we continue to hear of 998's that "blew up" due to deto or as dealers say "bad gas." Granted, lately it seems those stories are related to PEFI sleds. Why the apparent disconnect between what the tuners are saying and the reality of the owners who have had these sleds go down?
Even if someone gets "bad gas" or the engine goes lean, why does the engine "blow up?" I just don't understand why the deto protection system doesn't protect the engine??!!!! It should work even at WFO. Anyone explain this to me I'd appreciate it.
