But I am curious to see your timing. I'll look at my IAT's.
Car is noticeably quicker for me as well when no timing is pulled.
When you dialed yours back did the car respond by not pulling timing?
I figured you were from the emoticons(whatever you call them) I think a lot of people on the forum get butt hurt fairly easy, so that might be why you had to mention that you were just messin. I don't get bent out of shape very easily...
When I dialed it back the car did not respond by not pulling timing. It would still pull timing whenever it felt like it.
I dialed it back because everything I read said on 93 that timing was blasphemy haha. Not long after I switched to a 3gal mix of e85(think knock suppressant) and the car still pulled timing whenever it wanted to I wish I had thought about shimming my knock sensor.

That hot air is not accounted for in timing and minor detonation could result. The knock sensor does its job and keeps the engine safe, but you see the power loss. If you had the IAT after the IC then it would pull the timing instead. This is a good thing. IAT does not cause detonation when it is accounted for in timing.
If its in the MAF(like mine) it's a drawthru setup so it pulls the temperature of the air before it enters the turbo. going with a bosch IAT sensor at the throttle body is on my list of upgrades unless I decide to go adaptronics... But that hinges on me being able to find a cheap PTP kit like Slash's.

Ok, I'll bite. What was your e-85 mix and did you scale the injectors for it? Also did you try the e-85 mix after experiencing the timing pull with a lower octane mix? It needs to be a solid back to back test to know for sure...
Or craziness here, pull timing from that area of the map and see if the ecu stops pulling it for you... It doesn't require a change in fuel or extra hardware, and should give noticeable results.
Sooooo... I pulled 2 degrees of timing where I was having KR. I took a few logs today and none had timing pulled. Maybe I must have been on that razor's edge? Seemed to have picked up some power in the 5500-6500 range too, likely from timing not getting pulled Going to work on the fueling now that I tweaked the timing...
So a few answers. My IAT sensor is still with the MAF. I looked at adding a separate IAT sensor post IC, but the '06 ATR doesn't have a calibration table for that sensor. I would have to use a second MAF. I figured the cost and effort to get a second MAF wired and plumbed in post IC just for IAT wasn't worth it, but perhaps this is a good reason...
Yomom, I went back through some my logs to see if there was a difference in IAT between runs and it does appear there is a correlation in my logs...

I didn't scale the injectors for it....I scaled the maf. The mix was tried after experiencing the timing pull on 93 only. I could switch back to my 93oct only when e85 wasn't available. I daily'd my car so this happened often. e85 was used on nights when I was going to local meets for shenanigans
Guess I'll have to do what slash did when my motor is done from seeing his results
Well hmm... Looks like slash had some mild det... Need more data to be sure. Dunno about you yomom, I still wouldn't write it off as a false positive yet, but it's heading that way. E-85 done right should have removed any trace of det with the same AFR and timing compared to 93.
Pre TB also for now, This is extremely important IMHO. I have a few more installed just not hooked up and programed.
I've got IAT at the MAF, Ic radiator temp and Post IC. It's been very slow but I'm building an arduino that controls the IC water pump based on differential temps of all three. I've also got Pre IC mainly for testing effeciency and a water cooling system I'm working on.
Heck yeah! Your antics crack me up I loved it when you got yourself so worked up you got banned
As far as getting worked up goes, nobody eats as much crap from other people here as me and I generally don't have any issue with it. In that particular instance, choosing my words poorly had little to with your assertion. It was fairly minor compared to what people have said to me without penalty, or even getting Moderator status shortly after (hi Travis). But moderators are just as susceptible to getting worked up, etc. as anyone else, as well as also being more than fair and forgiving too. Bottom line: It was my stupid mistake. I take full responsibility for it.
Before you laugh too hard though, a friend's daughter was diagnosed with terminal cancer yesterday. It would be wise to remember that karma doesn't really give a sh-t about who you think deserves it or not. If your motor blows up tomorrow you will get my condolences rather than a Nelson-esque "ha-ha". Comparatively speaking, being able to participate on this forum is rather irrelevant in the larger scheme of life.
But then I suppose you don't really care that the comment I was addressing when making my little booboo essentially was saying your Renesis results are impossible to achieve.
Sorry to hear about your friend. I will say it seems highly insensitive of you to pull them into the forum and use as your defense. Which brings me to the reason I've been on your case lately. You come off very insensitive. You don't give others the same courtesy you are asking for. You don't live up to the same expectations you demand of everyone else. They call that hypocrisy. Maybe the reason you get a bunch of crap from people is because your people skills are lacking. Sure, you don't have to care about others opinions. Likewise no one has to care about yours.
You often have good information but when it's tainted with nastiness people will ignore it. Just my advice to you. Take or leave it. But don't cry when people toss your **** back in your yard.
Ya I wish I could do that. The problem for me is that '06 ATR doesn't have a table for IAT sensor calibration So I would have to use a second MAF plumbed in and cables up. Between fab costs, the MAF cost and the cable splitter with connectors to do it right I'm likely looking at $300 or more. Might be a good investment tho.
I'm still not thoroughly convinced that my pulling timing in the tune was the sole reason that KR stopped. After yomom asked about differences in IAT temps I did see a correlation in my logs. Weather has cooled off here lately so it could be I'm not getting timing pulled because it's not so hot. Still adds up to the same result.
I'm still not thoroughly convinced that my pulling timing in the tune was the sole reason that KR stopped.
No it was probably the sole reason the KR stopped. The most likely reason why it started having knock is the IAT was not accounted for in timing. Move your IAT and then tune it out.
I wish I had thought about shimming my knock sensor.
