I have an appointment tomorrow(Friday) at 1:00 pm at Technosquare to have my ECU dyno tuned. I had my ECU reflashed a while ago. Since then I have have an intake manifold and a header and y pipe installed. Im looking forward to some nice results. I expect between 10-15 horsepower. If I get less than 10, Ill be disappointed, and if I get more than 15 its a bonus.

If anyone is available, come on down to Torrance. The car will be there for 3 hours or so.

 

Hmmm, I might be able to swing by around 1.

 

Here is the location:

TECHNOSQUARE, Inc.
22521 S.Normandie Ave.,

Do you mind getting a face to face confirmation about the 5AT tune if its still worth it with the torque converter problem? I know people have done it, but want someone to actually talk with takashi. Thanks

 

You get one loud mouth who doesn't know what the **** he's talking about and a product's reputation just went to hell. I have the original TS tune and I can tell you that you WILL see gain as other 5AT's w/ TS have experienced. Yes TC robs power, but it's true with all TC's.

I will be there today as well, so Tadashi can look at my car and compare to some of the "problem" tunes, if he has time. If not, I can come back another time so we can put this issue to rest.

 

Thanks so much...it was their response that scared me by the way...not other 5ATs. i just want to be certain when I send my runfiles and dyno that he can tune mine according to the mods and not a typical 6th gen tune so to speak. PM me with updates if you will and thanks again.

 

i live like 2 mins away from there, i might swing by also.

 

I am bringing my flash drive so Ill have the run files, assuming Tadashi gives them to me.

 

Very interested in the numbers.
Bump

 

Fill us in Deus.

 

Tadashi was very busy so I didn't get a chance to talk to him about 5AT. I'm not sure if Deus talked to him after his session. However Deus' re-tune gave him more WHP and WTQ with his new mods( headers, IM, etc), so the TS tune isn't the issue. He has other VQ35 tunes that he can customized to your mods.

 

Cool, I wonder what the numbers were.

 

265/249

rhmax, that link isnt working; i just takes you to the main forums page

 

It works for me, but here is the slip. Notice the 7400 RPM WHP RE-peak. I hope Deus doesn't mind.



I believe the blue line is before retune, and the black line is the after.

Mark, can you reply?

 

Interesting. Dues' car shows 17 more whp than mine but mine has 17 more lb/ft of torque than his.

Talkin' about robbin Peter to pay Paul. LOL. j/k

The hp power numbers are not bad but I was hoping with the 6spd manual and all your mods that you would be at least in the 275-280whp range.

 

It may be the Kinetix IM loosing the low end pull while giving a little more up top. The torque curve isn't as flat as stock IM and peaks higher.

 

Blue line is my baseline reading, with my original TS reflash, the red line is with the stock program, and the black line is with the new tune. It really pulls hard in the midrange of about 3700-6000 rpms. Tadashi believes there is a restriction somewhere, possibly the b-pipe of the exhaust which is limiting the high end. Im probably going to buy a Berk Technology intake because the pep boys special i have for an intake may be restricting too. I may consider enlarging my cat-back but not sure yet. Remember, 99% of your driving is going to be in the lower rpm range than above 6,000.

I dont know if its my imagination, but the car sounds better. Maybe because its pushing more air through the motor. I know getting to this point with a car is expensive, but I think its worth saving the pennies. This is really a great car to drive with an abundance of power.

 

More carbon fiber + splitters = more horsepower

I thought everyone who played gran turismo knew this

 

Very nice numbers! You could talk to Cattman to see if they can do a 3" exhaust for you guys

 

Ill have to do it on my own. It wouldnt be practical for him.

 

I dont see how a 3" exhaust on NA would benefit. i think your intake is a valid point though.

 

and then you would lose back pressure and loss of TQ , good idea if you want to be slower than a Honda

 

The Berk Tech Intake and the NWP Spacers install made a big difference throughout the whole curve. Keep your shield though. I'd like to get one on my Berk intake.

 

Do you have any dyno numbers for the Berk Tech intake?

 

I know that numbers only count and a dyno would prove things. Just going from stock to spacers and the Berk intake you could tell the difference. I wish I had a dyno for you. I'll get one when I install my apexi afc. But this thread will be dead by then.

 

I assuming you guys didn't the dyno of cattman's 3" exhaust huh? Considering its 3.5L and not 2L or less, sometimes bigger is better.

 

Im a bit reticent to try a 3" exhaust. I am going to try to improve my intake first. Im considering Weapon R and Berk Technology right now.

 

I have seen 3" exhaust to give guys up to 12-15whp....

I think for deus it would definitely prove effective, also deus I would try a 3" intake setup, i bet you could see even better numbers if you did those two things, actually I dont guess you will, I know you will. I bet you could see an increase of 10-15whp+ with those two things.

 

I thought there were gains and also made a nice exhaust note that's why Cattman is fitting them in 5th gens. I could be wrong but you shouldn't lose THAT much pressure for 3" catback.

 

My intake is a Stillen short ram intake, but the mid pipe is one of those PEP boys ones. I measured the inner diameter of it and it measures 2 13/16". ALso, there are these plugs for hose hook ups that stick out into the air flow. I think I can do with a better mid-pipe, possibly Berk. What are eveyone's thoughts of a 3" exhaust for me? Is it too big for an NA car?

 

I don't know about berk mid pipe, I would say, do the 3" MAF and make your own 3" midpipe (or do a midpipe delete). you can order the materials online at onlinemetals.com. I used their stuff before and its cheap. Actuall I would say do a 3.25" inner diameter maf.

as for the 3" exhause, its not expensive to do so, I just put mine together for about 250-300 and I'm going to get welded to together, I'm doing an exhaust cutout later. but for an NA car it has proven to be beneficial dispite what everyone else has said, its a good mod.

 

I know there is a Land Rover MAF conversion I read about. Maybe that is in the cards?

 

This link isfor a guy who is selling a 3" midpipe he made himself.

No one should go past 2.75 unless they are boosted

I made more power but I have a true dual setup with 2.25 piping

go ahead and try it Ive already seen what a 3 inch exhaust did for my buddys VQ setup... 228 I belive ... lost of midrange power esp since hes SSIM

 

"Lots" of midrange or he "lost" midrange????

 

A lost , he was running a custom catback 2.25 and made 232-238 I belive , He change up to a 3 inch exhuast with a Apexi canister and only made 228 which was his best on the dyno jet.

 

I doing the 3" exhaust with my 3.0, but I have a bit more in the engine to support it. It is a good mod, and can prove to be worth it if deus does the intake mod and is looking to squeeze everything he can from it NA, thats how the guy with the 320whp NA 350z is running

 

Agreed, since DeusExMaxima has headers I think that a 3" exhaust will help even more. But for a car running stock manifold, nope.

 

where did you see that , most guys that are N/A breaking 300mark on 350z have at least Cams and a botton motor built.

My first run made 241 HP and 252 TQ
My Last run I made 265 HP and 271 TQ on 110 octane.

Im on a slipping tranny , no 3rd gear and untune Utec and 20s and I was able to squeeze this much. After my tranny is fixed imma go again with a tune on the UTEC and by then I will be doing the SSIM mod since I have a spare manifold.
