I still argue (until someone proves otherwise) that the old tune doesn't contain the spark advance data change (because it wasn't part of the tune) and therefore, when adding the old tune back on, it wouldn't "remove" or set the spark advance back to the previous value, when applied.

If not that, or another reason, what's being said, is that one of the tuners is fixing numbers, which is ludicrous in my opinion.

yeah, it definitely seems like that's what he was suggesting. i'm personally going to quit following OP's progress, as he clearly wants this exhaust to fail.

the exhaust is amazing in quality, sound and performance. Tony provides arguably the best service in the industry. what more can you ask for?

OK, thanks.

I can't find the tuning section i thought i remembered about being able to edit specific functions, ie. only edit the values you specify.

Based on that, the only other conclusion i can come up with, is that someone is calling the tuners liars

That or there is some kind of equipment irregularity;

The A/F ratios are almost identical in the SZ tune, in the CAT tune, the SZ A/F was all over.

Have the manifold and couldn't be happier with it. All I want is the right catback and my setup is exactly what I want. Reliable and a better drive than the stock car.

hey mate

i went from stock to E370

Oops. Got mixed up with the threads. Thanks.

Quick question, how do you think it compares to fast intentions? Aggressive growl going WOT?

FI has the hiss. Motordyne doesn't

I'm interested in the comparative lack of comments by the OP actually

You see, some of us like Motodyne, are in the performance business and make and actual living out of it. Three generations of engine builders and performance shop owners are part of my family, for good reason. That's experience, conviction and dedication to the sport. Not like you Nar-du-well hobbyist owners, who drift in and out of the sport. You're the type who believes they've got the pulse on engine building or tuning, on the contrary you haven't got a clue.

You lack the knowledge and conviction but are always prepared to ridicule a manufacture, about something you don't understand or comprehend.

Frankly, you believe your qualified to give advice to others but in reality, people like yourself cause more problems then good. You've already given out enough of bad advice through previous threads.

Bolting on a TT on a 3 year old G37 is no great feat or accomplishment. Leave the NA engine building and tuning advice, to those who have enough experience not to lead others in the wrong direction.

You're the worst kind of troll. You only jump in when everything else has been said and done, just to add your BS and stir the pot.

Last time I checked, this was a 370Z enthuiast forum, which you don't seem to own.

Why do you feel the need to call out fellow members? Why do you continue to boast what you have done in the past? You do not need to impress us with your resume. We are all enthusiasts here; some more than others.

No one is hating on Motordyne. This is an E370 discussion thread. I posted results that was not in favor of the manufacturer, and got heat for it.

I have paid for everything I bought from Motordyne. No partial sponsorships, no discounts. I do not owe Motordyne anything. Sure, Motordyne offered me a free tuning session and I accepted it. In addition to the free tune, I was also offered a free set of revised ART pipes with free install and dyno for R&D by Motordyne. Do you think I accepted that? Why do you think Motordyne did this? Are you calling me ungrateful because I did not readily accept the retuned numbers from Church and should have stopped there?

Maybe this is all a misunderstanding, perhaps a technical difference between dyno machines. The run files have been requested so we may have our questions answered shortly.

OK, someone answer me this, did, or did not, Seb from SZ post earlier on in this thread?

I've just gone back and browsed through, i couldn't find his posts at all, i could have sworn they were there as he originally took offence to something Tony@Motordyne said.

I also remember someone mentioning that there was either nothing to gain from tuning spark advance or that it couldn't be tuned on the 370. Someone please help me out here, i don't like where all this is heading.

Seb deleted his posts about the situation.

MaDMaXX · 03-19-2012, 10:26 PM

So i wasn't mistaken?

Now forgive me for jumping to conclusions, but, how bad would it look (after saying 370 can't be spark tuned) if CAT then tuned that and gained power, then SZ took it back and showed the loss?

I don't think that'd look very good...

The deletion of posts both by SZ and Motordyne occurred on 3-1-12. My tune date with CAT was 3-13-12. The deletion was performed by admin/mod. Perhaps AK can shed some light to why.

I would suggest guys STAY ON TOPIC!! and keep the nonsense in the Lounge!

The posts were deleted by me at my descretion, And only at Tony's request to avoid anymore confusion? Those posts have been restored.

Again STAY ON TOPIC!!

Thank You.

Hi Seb,

Just so you know, Shawn at Church Automotive Tuning was not given any details or background on the tune or comparison. The only information he was given is that it was previously tuned and to see if more could be made. No other information was given to him.

Other than the possibility of the ECU changing its short and long term trims, I can't say why they are different but I will vouch for Shawns integrity. He wouldn't fudge results as some have hinted. Not for me, not for anyone. Nor would I.

I'm thinking it is quite possible that both of your results were/are accurate at the time of testing.

Jason,

Here is the additional analysis of the 3 best runs of each system. The 3 runs were averaged together to give a clearer picture of the final results.

This is the 3 averaged delta plot of best runs with the AF tunes.

At the end of the day, it didn't quite meet your expectation of making 5 more HP, but it was close.
