Please do not give advices to switch from Power Pack to some non carb compliant tune. This thread is for those who either have to adopt to power packs or switch back to oem tune.
Anyways. Ways to check - roll driver window down, drive next to something like cincrete wall - freeway divider in heavy traffic will do, press accel. pedal for some acceleration and tell us if you hear
so called pinging. If you do not hear anything with windows up - this does not mean anything.
I do believe this is unhealthy detonation. This sound is very familiar to me. I used to live in a country where fuel availability used to be a big problem, so people would use whatever they could get rather than fuel their car was designed for. If octane rating was below expected you'd hear your engine making this sound. It was very common to hear around. I cannot say that most the cars would end up having piston damage. If you were careful and use lower gears to minimize impact you'd be good. If you neglected the sound and whip your car on a day to day basis, then you could get engine damage. It was common enough so that mechanics would have small museums of parts damaged due to detonation.
Personally - I installed power pack with octane adjust option on to begin with. I do have two oil catch cans. I am limited to 91. I filled close to empty tank with 91 before pp installation. I am still on the first tank.
First tank still has some 87 gas remains. I will empty tank as much as possible, fill with 91 again. If detonation does not stop I am rolling back to oem. Or maybe there will be som good advice here.
From my research it appears this is hit ot miss. Some do not have pinging on 91, but some have on 93.
Frpp response - do not worry about it - but I do not buy it. As mentioned above - destructive features of fuel detonation are well known, and just "do not worry about it" will not cut it for me.
If I have to rollback to oem - I will make all efforts to return it to ford racing.
