Causes of knock retard
Hi, I was just wondering what woud cause the ECU to pull timing except for knock sum?
i don't understand why my timing numbers are 2* less than what the map is set for? I've logged the octane values to make sure i wasn't running on low octane maps and i don't think so since it shows 100% through the whole log. I know that intake air temps and coolant temps might also be a reason for the ECU to pull timing but both look normal to me (36°C for IAT and 84°C for Coolant temp at WOT).
Thank you
