new to tuning!

[ti's 97 dsm]

Alright, apparently I am not very active on this site. On another hand I am also new to dsm link/ecm link! So I have it so the CEL pops on when more than 2* of knock, I did a 3rd gear pull and logged it...I have no clue where I am at now so any help would be greatly appreciated! Thanks!

so did the CEL pop on? i don't have link so i can;t read it but have tuned with it before!

Well it just pops on and goes away. And Yes it did. Says I have 4.6* of knock, it starts at 5990-6356.

you can try adding more fuel or taking timing away at that point to see if it goes away.... is your fuel pump rewired? what is your plug gap? new plugs wires? all maintenance done?

Everything is up to spec, I was told that if i dropped it a psi it would go down.

Your tps either needs an adjustment or you didn't have it to the floor or your linkage is out of adjustment. your coolant offset is set to 10 should be 0 unless you have a sensor issue. your timing looks a little out of whack too. but i could be wrong. if you can post up an idle and cruise log, and lets look at the basic stuff to make sure your set up right. also what size injectors do you have? ### you are set to 1014 cc's . one last thing make sure you log the combined fuel trim for the cruise and idle log.

His profile says he has 950cc injectors.


What boost are you aiming for? Your BoostEst value just keeps climbing over the whole log until the very end, where it levels off for a bit.

Run through this:

I'm assuming you don't have a wideband, correct?

Go into Edit > Captured Values and add:
-OpenLoop
-LTFT Lo
-LTFT Hi
-STFT
-CombinedFT
-SelectedLTFT

Then go into Edit > Displayed Values and add all of those things to the "To be displayed" list.

What's the reason for the coolant offset? Not that I'm arguing with it, as I run an offset myself. Just wondering why you have it set.

Go into the ALS/Knock tab and change the Knock Sensor Control settings to something like 2500-3500 for RPM and at least 25% for the TPS. This helps prevent phantom knock from tripping your CEL.

And to be safe for now, if you don't want to drop boost, I'd take the timing values from 5500 RPM and up and drop by 2-3*. Keep in mind you can do this either by the sliders or with the Direct Access tables, but please choose one way and stick with it. Most people prefer the tables, but it's really up to you.

My apologies man i'm so used to people not updating their profiles that i forget to check their profile.

Sorry if I do not answer every question, my attention span is a little short. But everything is set from the previous owner, on my last dsm I just brought it to get tuned, so Ill prob be doing the same with this one but I was just trying to pick up some advice to see if I could try and learn this.
