Alright i thought i'd post this question to the rest of the group.

Everyone should know me from the ODB1.5 ECU project (95 PCM), we've come pretty far but im running into a problem.

I've got some basic tuning done, fuel/timing etc.... and engine is running great. Even got the PE tuned very well, including time to PE set to 0 so when you mash it, it grabs instantly. But here's my problem.

When car is not in gear, and i go all to the floor, engine rev's, and between rev up, PE and rev limited the engine will register 200 or so knock count. It's only doing in when not under a load???? I've checked my pe maps, and even loaded a stock bin, where it still shows it the 200 pe count?

Could that be phantom knock.

Engine is ln2 2.2 in a 95.
