Not trying to flame here, I'm just trying to understand what I'm reading here.
good question... i wondered that too. from what i understand, the knock signal isn't really worthwhile to log, especially if the sampling rate is low. but yes, 0 = no knock and 1 = knock. it is possible for it to show nothing but 0's even though knock has occured.

Neither does you sticking your nose into it. This is an issue between Keegan and S-S (and to some extent Ed) and should have stayed that way. Everyone involved had their say and presented the facts as they saw them. There was nothing left for Ed or Keegan to respond to besides comments you interjected after the fact. Leaving the thread open only promotes arguments and personal attacks. We don't need this drama in here. It's not your fight, it's not Ali G's, and it's not anyone else's.

I'll leave the thread open, but I hope folks will let this drop as it is making all parties involved (especially the ones that shouldn't be) look bad.

Info from StevenDone of EcuTek:

As the revs rise, the knock sensor switches off at 6200 RPM on a US WRX, then back on again at 6100 RPM as the revs fall. So the sensor is active at 6000 RPM.

Nate, sorry you got dragged into this. This whole onslought was unacceptable, unprofessional and underserved to you and the whole crew at Subaru Specialists.

I never heard of EQ tuning until today. Unfortunately this is one of those first impressions I will never forget.


EDIT: my apologies to the moderators, I had this sitting on my computer and posted without reading Egan's last post. I agree completely as I posted earlier this is not the place. It was just frustrating to see Nate dragged into this the way he was.

Based on the complete lack of knock sensor activity, even when you claim you heard audible knock, I'm a bit skeptical that it was there during your datalogging sessions. So, you're attacking Nate's tune by claiming that there has been significant knock in the recent past. Are you saying that if you had tuned the car, that detonation would never have occured?
Please see my above post on the topic of the knock signal fiels as reported by DD.
And yes, if I had tuned the car, it would have not experienced this ridiculous amount of knock unless there was a mechanical issue after the tune. In which case, if it had been brought to my attention, I would have done something about it and not simply dismissed it.

Again, you claim to have heard audible knock with absolutely no knock sensor activity, in a WRX with a catless 3" turboback? Sure pal. The dip in timing is quite obviously present, but it sure looks to me like it's there by design, not as a result of the ecu pulling timing after sensing unsafe conditions.
Again, see my post above about the knock signal field in DD. And yes, you can hear knock even with a catless turboback if you know what to listen for and listen carefully with the windows rolled up and stereo turned off. BTW, what past experience with Subaru ECUs makes you qualified to say that the abrupt dip in timing is there by design? Maybe Nate can comment on this... was that by design, or do you agree that it is evidence of knock?

So you're accusing Nate of disabling or altering the learning ability of the ECU again? I stand by my assertion that the car did not detonate during either of the datalogs you took.
And yet again, you misread my post. I never said Nate disables anything. Atleast partially altering the learning behaviour of the ECU, on the other hand, is necessary for a good tune on a car with these modifications. So yes, I'm almost positive that Nate, like any other tuner, modifies the learning parameters atleast to some degree. You can assert whatever you like, but you have no knowledge or reasoning to back it up. It is very obvious to anyone who knows even the basics of how to read a DD log, that this ECU is responding to a lot of knock.

Did you just say that when the ECU calculates load above 4.0, it reads from a lower load cell? Or did you say that the fine learning table you showed us wasn't the same one that Nate put there?
I didn't say either of these things... not even closely. I guess I'm talking over your head on this. Re-read what I wrote, and if you still don't understand, I'll try to explain it more clearly.

I quite obviously used changed paramters to grossly exagerate how road dyno results can be tweaked to meet the desired results of the user. To suggest that a 10whp difference on a road dyno means anything is, again, ASININE. It is completely not repeatable. Even your stock road dyno showed significant difference from one run to the other, and that was presumably within minutes of each other. The point is, a road dyno graph can NOT be used as objective evidence in any way. To insinuate that Nate's tune on Keegan's car didn't make the power it should is twisting evidence to it's own ends. If you're suggesting that you can tune Keegan's car and make 215 whp on Nate's dyno, you're wrong.
Of course you quite obviously changed the parameters, which makes your own argument completely asinine. As I've said, I never change the parameters from run to run and I can easily back that up if you really doubt that. BTW, a road dyno measures the car's actual ability to accelerate on the street, not sitting on a platform on some rollers with simulated load being applied to the wheels, so the road dyno is actually the definitive way to compare a car's accelerative power when performed propperly. I'm not suggesting I can tune this car to make 215whp on nate's dyno. Rather as I stated clearly, similar cars that I've tuned with similar mods make 210-215whp on my road dyno on the same road, with the same parameters under similar conditions. Again, please stop twisting what I clearly say into your own words.


The only thing clear is that you think you need to attack the work of other tuners in order to establish your own name. Nobody here (well, maybe one person now) wants to see you or anybody else fail in your attempts to become a professional tuner, but leave your competition out of it. Attacking a reputable and established shop like Subaru Specialists has cost you more potential business than it will ever gain.
I never attacked anyone's work. I actually gave Nate the benefit of the doubt and suggested that its much more likely that there is a mechanical issue with the car rather than a tuning issue. The fact that Nate chose to ignor the issue at hand is not my fault and I will not be attacked for it.

Thank you for bringing a little sense to all this nonesense. Everything that needed to be said had been said when you locked the thread. And now its just a waste of time and energy to keep up with BAN SUV's uninformed remarks.

I'm sorry if this makes a bad impression on you, but all I'm trying to do here is to stand up for the data I provided to a fellow subaru enthusiast. I never intended to bash Nate, but I was not going to let fear of that stand in my way of allerting someone to a problem with their car.

Don't worry Nick, its an unfortunate issue but it'll come to term soon enough. I really fell this thread will run its course very shortly, as it seems pretty much everything that needs to be said has been said. Posting your own thoughts certainly doesn't stop this from happening.

Its always sad for a shop to lose a customer. I personally give Nate the benefit of a doubt because I've known him and the shop for quite some time and I believe him when he says it was unfortunately a miscommunication that has gone out of hand. I'm also willing to give Keegan and Ed the benefit of the doubt as they don't seem dishonest (as far as one can infer over the internet without actually meeting either person). Plenty of us have had different experiences with Nate and S-S and this is perhaps the worst I've seen. It sucks, but its bound to happen as the shop grows and matures to become part of the respected community. People get busy and what might have been an honest attempt to rectify a situtation can seem unacceptable to the other party. Its sad, but will happen.

I know the shop feels bad, but whats done is done. Nate had and has offered to retune, but I guess emotions ran high enough that this wasn't acceptible. I surely hope calibredwrx can find a solution he can be happy with. And if there is a real mechanical problem with his car, I hope it can be fixed.

I would expect you to alert your client and the tuner, not help contribute to this mess on an open forum. I can understand the snow ball effect that has occurred, but when Nate asked you to stop, the professional courtesy to stop should have been afforded and the posts should have ended there.

My technical knowledge of tuning is painful at best. My comments strictly have to do with the manner in which Subaru Specialists was brought into this forum; accused of doing something wrong. In your own best interest, I would just stop posting, call Nate, take him up on his offer. Nate is an extremely level headed and talented person. My guess is it would end up a productive encounter rather than the confrontational one that has formed here.

Nick
