ECMlink huge knock problem. First log

[milby43]

hey guys, I just got this hooked up. Seems i have a knock problem? This was just a cruising log with barely going into boost.

mods are on page if needed. Never done this before so, what to look for when logging would be helpful.

Thanks.

Do you have a legit version of DSMlink/ECMlink?

 

[milby43]

I had Tom Dorris from ECMtuning show me how to log without the chip.

 

[snowborder714]

Um, can't say I've ever heard of that before

Two things usually are wrong with the sensor to cause radically high readings.
1. It's bad. Look for black goo coming out the back.
2. It's not torqued down properly.

I'm serious though, have emails to prove it. Although I dont want to show them without his permission of course.

And with tuner pro rt, it was showing alot of knock as well.

I'll try what you said, thanks alot.

That log is...well... useless, since there is nothing really to look at. I've never seen anything like that before.

See something new every day.

 

[milby43]

yea I understand, like LTFT STFT and stuff like that. Im saving for the chip, should have it by the middle of april

As they said not a lot to go off of... .


Hmmmm Tom is Really showing people how to do this ???

could be a faulty knock sensor, I would look at the TPS to make sure its set properly, and put a timing light on it and verify the baseline timing. Looks like anytime it boosts it goes to spark knock.

 

[milby43]

Just set the TPS today, seemed to be smoother. I think i might try a different tps though.

Timing light was just on it the other day. But Ill try it again I guess.

Tom isnt showing people how to, he doesn't want to give support. It doesn't always work. It was just a last resort for me.

I have lifter tick, could that be it?

I don't see the point if that is all you get, since that "log" is pretty much useless.

Yes, a knock sensor can pick up lifter noise, but I wouldn't necessarily jump to that conclusion.

 

[twdorris]

Could be a loose knock sensor. I had my 95 Talon do that same thing when the knock sensor was rattling around loose.

Could be a bad knock sensor.

Could be base timing is way off.

Could be a bad knock board inside the ECU (although I don't think we've ever seen that before).

Could be some other problem inside the ECU that's throwing off the knock board (although, again, I don't think we've ever seen that before).

And, yes, you can log a stock DSM ECU with ECMLink (except the 95/96 ECUs). I really didn't want to open that can of worms, though.

It's extremely basic and I'm sure there are bugs all over the place. I didn't really want to release something that had so many potential issues. It would end up giving the wrong impression of our full logger, which is exactly the opposite of what I had in mind when I first added this functionality a couple years ago.

I thought it'd be a great way to let people use our basic software for a while even with stock ECUs. Then they might eventually want to upgrade. But I only had about a weekend to work on it and the results weren't what I had hoped and my time ran out anyway, so it stalled.

Sorry, but I really didn't intend for this to get posted up. But now that it is, please understand why I'm reluctant to post any instructions for how to do it. I guess as long as I make it REALLY clear on the instruction page that our full logger is significantly better, maybe people will understand.

Hey Tom I didn't mean to bring it to the public like that. So I apologize for the inconvenience.

I'm going to go through a few things tomorrow, knock sensor, TPS, timing, and idle.

Again thanks for the input, I know this maybe an aggravating annoyance(someone doing something...half ass), but I really appreciate the help.

Ill fill you guys in tomorrow night EST
