As I keep reading about Open Source ECU tuning (free reflashing software for Subaru's and Mitsubishi's), I find more and more information. As much as I want to be able to just flash the Stage 2 maps that are available, they're not as tried-and-true as the Cobb maps, and definitely no where near as confidence-inspiring as an ECUtek tune. A wideband O2 and EGT sensors are pre-requisites for me, but then there's the subject of knock. I had always thought knock detection was done via logging; seeing when knock was occuring (and timing being pulled) and tuning accordingly. That has scared me because I'd rather know I am pinging while it's occurring... not after I do a WOT 4th gear pull and see 30 counts of knock.
Reading the Enginuity forums, I came across a pretty interesting (to me) thread,
"Det cans, Knock Link, Knock Lite. Anyone using them?". Basically, has anyone had experience using Knock lights or stethoscope-like devices to pay attention to knock?
A device like
this one at the top of the page seems very simple and easy to rig up, so I was thinking of doing so before I start reflashing my car so I can get used to what I should be hearing. The TXS knock lite also looks like it's now on my list, but I'm not sure.
Anyone with any experience tuning their own car feel free to chime in!
edit: ughh sorry I posted this in Engine Performance, I thought I was in Engine Management and tuning... what a noob. Mods please move.
