So I pulled out my scanner out and pulled my code. As anticipated its for idle higher than expected. A good note I cut that ripped coupler where it was ripped and threw it back on and has been holding fine. Actually think it will hold too as now its thicker rubber where its clamped. I am pretty sure I will be switching my iscv steps back to lancer for a/c on as everytime now it revs to 2k when I switch a/c on.

 

What ISCV did you use?

I used

 

Completely stock evo right now. Well actually might be running lancer values in the idle Stepper table ill check in a few on my phone atm.

 

grr how can i add to my lancer xml so we can find out the knock gain settings for the stock lancer knock sensor??

 

Here is what I am currently running. Definately going to be changing some things around its starting to die on me pretty consistently at idle. However I think I forgot to change the high intake air temp steps back to evo settings

 

I dont think they were ever defined, however RS did find them, message him I cant remember if he posted them here or if I asked him and got them. I cant recall what they were right off hand

 

So I went ahead and changed everything back to stock evo. Does seem a little better to be honest. Nothing is killing these dips though :-/. We will see if the car dies I will leave it as is for now. So while I had the laptop with me I decided to do some pulls. I just went out and did these back to back same road 2 pulls each way. These are graphed in chronological (spelling maybe right?) order. Top is first pull, bottom is last pull. No tire slip and flat road so take these however you want.

 

Why not just download my xml and rom's and find out?

Then I wouldn't have to recite them from memory right?

Just so happens i'm on my laptop right now so i can just look at it :P

Multiplier 18
Single gain 3
Triple gain 5

Before messing with the gain up your multiplier. The stock lancer rom only has one knock multiplier since it was never meant to be turbo'ed which turns out to be quite high. The evo has 3 settings for RPM based knock metrics I believe it starts out way more sensitive than the base lancer than works up to a 20 by the end of the RPM band making it less sensitive in the higher rpm area.

Your motors are probably extremely noisey. I would guess the single cam makes quite the racket with that small head less dampening and thus more signal to filter out on the knock sensor. You should probably set your evo knock multipliers to begin at 18 like stock and work it up to 20 like an evo by the high rpm limit maybe even more if it gets too knock friendly.

 

Didnt realize you had actually put them into an xml lol.
Just to throw mine up there. These runs I just posted I have knock multipliers of
Low rpm-19
Mid rpm-20
High rpm-20
These 4 runs I had 2 that were completely knock free and 2 with some counts of 1's and 2's.

 

those look nice^ how does the knock gain work? what does a higher number or lower number do cuz evo has a 2 in the low and 7 high

 

I have mine set at 3 for single gain and 7 for triple gain. What I gather from Merlins guide is it effects how it calculates the gains for the Knock_base and knock adc_processed Im thinking. Basically same functions as the multipliers higher the number equals less sensitive looks like.

 

alright ill give that a try... i have 2 and 5 righ now righ now

 

Essentially it effects the knock voltage ceiling so higher numbers mean less sensitive yes.

I wouldn't worry too much really all knock I've seen pegs the crap out of the sensor.

 

Yeah ive noticed that knock makes itself pretty apparent. So I adjusted the biss some more today while logging my isc trims and got the trims both at -1. Also fixed the a/c steps table I cut the entire table in half so now my idle stay pretty much constant with or without a/c on. While I was logging I went ahead and took a video of my idle dips to see what you wall think.

That's totally not what I expected to see. I think that, while the BISS method has your base set properly, and your values in the idle table seem decent....I think you might have something else up though. What else happens, like...afr dip, or...i dunno, something else is affecting it.

You did a boost leak check right? Does it dip when the BISS adjust mode is on? That will narrow it to being either in the tune, or something mechanical.
