Haltech boosting noises

boosting noises
How would you tell if its preignition, pinging, or detonation or are those all the same thing? I have this kind of metallic rattle when going into boost which has me staying away from it. I bumped down the timing about 3 degrees around the whole map and it has not changed. The only different thing i've done was put 89 instead of 93 because the station was out.

What ECU?

e6k. Im sure the trailings are not backwards unless it just fires them different. Or that could be the cas is in backwards right? I'll swap them and check later today, but when i timed it first they were sparking right at the marks on the pulley. I did have to put the trigger angle to 101 for them to line up though which seemed kind of high to some others i've seen.

Was this motor apart? Did it have any switcheroo on the front hub/pulley pair?

How to find TDC with a 2nd gen motor:
- Purchase Racing Beat or other aftermarket, machined pulley/hub piece w/ known good timing marks
- Remove existing pulley and hub
- Insert New; rotate to TDC
- Remove new; re-insert old, chisel a mark on pulley for new TDC mark
This is a bad enough problem on 2nd gens that I carry a known-good pulley/hub combination with me in my bag when I go out of town. It's an annoying pain in the rear, but a critical enough thing to warrant it's necessity at times.
Front hubs and pulleys are *matched pairs* that should not ever be mixed up!!!

Its wierd though. I found that website were you look through the rear plug holes and mark the pully where they are both between and thats were my pulley is which would mean that it is a tdc and the cas is right on the mark. The base is turned to the far clockwise position but there all lined up.

The 3 and 11 tooth offset are a major calibration value relative to how the CAS is stabbed in with respect to the engine being at TDC -- remember the gear on the bottom of the CAS? Rotating it tooth at a time is the same thing as changing that Tooth Offset figure. Stock insertion method will necessitate an 11 value in that Ignition Setup page. Otherwise, if you follow HITman's preferred method, it requires 3.
