Tuners around GTA

Reality

@Megan370z
It really seems like you are going off on a tangent and I find it hard to understand what you are trying to convey.

Why do you keep bringing up this "Racing world"..
-are you a racer? Is the OP a racer?
-What does tuning for the street use have to do with the racing world?
-Are you running a race tune? (with an automatic??)

And I will ask you again..
-If the OP is happy with the results, why are your panties in such a knot?

I guess we will see soon enough, exactly what you are out to prove..

Am I a racer ? my answer is = im a wanna be ! and yes I went on the track with my 350z roadster with the whole body kit and no power mod but i was passing people with a better setup than me.
same with the 370z this year.

tuning for street or racing ? or even is the OP a racer ?
well ok the OP prefer to have gained some minimal gain at between 7000-7300rpm on the dyno sheet and is very happy with it ... i would be mucher happy to have the middle-higher powerband that being superior in the last 300rpm

does I have a race tune you say ? with an automatic ?
go ahead and start that debat on manual vs auto !! haha
yes my 370z is an auto my 350z was a 6mt

yeah my 370z is going to be more and more a track car than going on the street
so who care ... only me thanks

Reality

That's what I thought..
-So you were passing modded z33's in your OEM-NA form? and you were doing to same to modded z34's!?... Obviously you are the better driver


There is no debate.. Those who can, MT.. Those who can't, AT... Its quite simple


Congrats, you are the first owner that I know of who purchased an AT so he could track more.
-And you are right, nobody cares about your setup.

^I am not sure if you missed this the first couple of times, but you never did answer...

hahah you make laugh soo hard man !

you are aren't happy that I bash at APH because you love them soo much that now you are you doing some personal attack just to try to discredit what Ive been saying

good job kid , your just lowering yourself


if APH didn't screwed up their dyno setup in the first place , I'm sure we wouldn't have got that discussion

clap clap to APH !

the graph shown that he was reving to 7300 rpm which in facts is false , he was around 6500-6600 rpm ,, because of the screwed up gear ratio
APH did NOT even tune the higher top end , the last 1000 rpm which the engine could be knocking !!! , if they did , its not on the graph
Clap clap to your perfect APH shop and his fan !




all of that because some guy cant see clearly the actual number and the performance relied to it.

stay in your world of the peak HP ,

Megan370z

yup the z33 part in true as for the z34 part in 2010 i was even faster , thanks

yeah yeah yeah what you said isn't that true ,, but only in your own head,, how come the auto transmission are getting more and more into the racing ? that are out performing the manual ? get out of your town and look what is happening in the world .

I pretty much totally agree with you , no body care about my setup , it just gonna be more secret , as for tracking more with an AT ,, you got me wrong ,
the car is going to be a track car only in the future ,, having the AT to track more ? lol not really , can you read ?

I do not care if he like it or not ,
What I care is the result provided . he like it ? good for him .
we are in a free country man and we are aloud to have our own opinion.

Hey guys just take it easy. We're all VQ brothers around here and helping out each other. Megan, I like Sasha and shouldn't have come hard on him but wasn't happy definitely with his tune. That said I want to leave it like that and wouldn't want to drag this on for any reason.
I had a reason that the tune with APH was different than with Sasha's, I'm sure my butt dyno didn't let me down in comparing those two.
That being said and since you spent so much time analyzing the graphs, I said let me look at those again and there must be a reason why my butt sensor feels sensitive to these two tunes.

Here's what I found

Though gear ratios are different but Megan you used the numbers to prove both the tunes were same or that Sasha's was better. Take a look at the dyno graphs again that I've attached, I had marked some mid points to get some approximate numbers, sorry if I'm off I tried my best. The torque does show nice improvement with APH and thats where my butt dyno picks it up.

APH or Brian do not know anything about my tune with Sasha and I would appreciate if they're do not know and I don't feel any reason they should.

Megan, I understand your frustration and you're making more harm than good especially for Sasha. You seemed to have purchased M370 recently and am sure you would've done your homework with it prior buying it, ppl have had different results with that.

Next time I'm in T.O, we'll go for a run and see who's faster.


cheers.

Draper ,
what we have been discussing is APH didnt setup the dyno properly and the result of the gain are slighty affected by this.

you cant compare the graph of those 2 dyno together
because 1 has the correct setting (SG)
and the other 1 has incorrect value (APH)
you can only do an average of the gain with one and check the average gain with the other one ,, you cant just say hey I had 300 hp with his but 260 with the other one.

even that ,, there is no Dyno that read the same
APH is known to read higher than SGM one...
but on this one since the gear ratio isnt correctly set ,
it throw everything off ...



in conclusion ,, IF i was you . I would have 2 choices
either chose to go back to APH or SGM and get a few proper pulls with every tune
and make sure this time that the dyno is set correctly and get tuned on the top end since the tuner didnt rev the engine to redline ,,, he didnt even go into your peak power since he stoped around 6500-6000 rpm .. the 7300 rpm you see on the APH dyno sheet is the result of the incorrect value in the gearing ratio


that way you are looking to see which one is the best one...





look as an example when first I went to SGM for a tuning , yeah I was like you , mixed feeling with the gain , so later on I did some street tuning and being VERY aggressive with the ignition timing and afr ... then I went back to SGM to see 4 different map and see where we can borrow the best of everything ,

put everything together , we managed to get gain everywhere
2 of my street tuned map were having knock , we corrected it and made more power.

draper

Megan again, please look at the delta/differences in power i.e. from APH tune to Base
and Sasha to Base.
Regardless of gear ratio or different dynos, it is obvious there seem to be higher numbers (more than 1 - 2% ) throughout the power band and better than Sasha.

I didn't know you went back to Sasha to get a proper tune as you were not happy with the first one, I was in the same boat as you were and had to go to APH to get a proper tune. Sasha didn't want to try again, I gave him other options as well which were fair to both of us but he didn't want to go ahead. So I said 'oh well'.

Brian at APH made sure I didn't have any knock after the tune, and as I mentioned before no CEL/SES light till now which says a lot about the tuner. One usually gets this light if the AFR numbers are off and that throws off other stuff. It happened to me right after i got the tune from Sasha.

May I ask what was the gains you made from first tune to the latest one from Sasha?

Megan370z

Draper ,
those 2 picture you just shown is one of APH and SGM , thats ok

You said in your post when you posted the first time that this one was 1 pull from the base pull and then a pull with the APH tuned one

ofcourse you will have the big gain from the base tune...

and the one on SGM was with Sasha tuned map and your Cobb map which is already tuned from them,,
since you came in his shop with an afr 12,5

from the factory the 370z run lean ,, not rich like that , you even have breather mod and exhaust ,, if you wasn't tuned when you went to SGM ,, you would have been in the 14.x AFR

then the big gain would have shown like APH in his graph

Megan370z

on a side note ..
no I did not bought the M370 from MotorDyne

I bought an used 350z HR intake manifold with both Throttle body for my projet
Since someone showed the picture of their M370 . i took advantage of it and Did the modification myself , I dont see myself buying the same item for 900 $ when I bought it for 100$

Megan370z

aaaa I hate missing stuff
sorry Draper

I do not have what you are asking since the only sheet I have with me is the last one I got the last time I went to SGM and I didnt ask to have the one from the first time he tuned me .

if you add the gain I had the first time and the gain I got the second time
it should average between 5 to 13hp / tq
those are my word and dont put to much weight on it because I go from memory

but I do remember the first time I got in at 268 whp and left at 280 whp (6800rpm) and droping !!! since i do not have a CAI

Im pulling vacuum from 6400 rpm to Redline.. which mean there is a restriction in the OEM Intake system with the freeflow exhaust I have

draper

Megan, its a smart thing you did about the M370 and this is what some of the ppl were asking about that. Can I ask what you've modified besides the bolt holes? Did you do a before and after tune, just to make sure its worthwhile doing this mod.
Not sure if you can add gains from first tune to second tune as there are other things involved such as temp, gear ratios , etc etc.
I had to ask Sasha multiple times to get me dyno stuff, and he forgot to put the battery cover back in my car after the tune and which I still yet to recieve it.
You don't have too many mods and shouldn't be getting any knocking. Are you doing tune with Cobb or Uprev?
Either one, try getting a tune with APH as you should be paying only for a tune and that shouldn't take more than two hours... my two cents.

Megan370z

just to throw something
here is my first Dyno with my 370z at APH
the car had no mod or tune , 100% stock

the gear ratio is correct
I did 5 pull and those 2 there are the lowest and the highest one
you can see a big difference


Pull # 2 gave the Biggest number and pull #5 gave the lowest one.

always do more than 2 pull to check the accuracy of the tune...

draper

thats pretty good numbers for stock. And if I were you, I would do it again, as it is right now and one after tune if you were getting it.

Megan370z

You can check my DIY , picture and everything what I did ,
the only part that I did not covered was making the hose setup.
DIY 350zHR Intake Swap

As I said previously , Im going on his dyno next week to test the new manifold against the OEM on the 370z. ofcourse I will not knock since at around 15 degree C I lowered the timing ignition and the AFR is rich enough I should not get a knock

Like I told you by PM weeks ago , I have the Uprev tuner package .
I may go at APH and spend some time there to see what they can do in the future, but right now im focusing on the same Dyno !

2 head is beter than 1 , doesnt mean 1 is better than the other one ,, just things are done differently
