Technosquare tune
 

I just had my ECU tuned by Technosquare today and according to my butt dyno, there is a difference lol! The car feels more responsive and more torque on the low end side. Before the tune the Z felt a little sluggish in the low end due to HFC. Now after the tune she feels more "alive" if you know what I mean?!

Also before the tune at WOT 2nd to 3rd, the Z would just squat. Now 2nd to 3rd breaks the tires free. I think this is due to my rev limit changed from 7500 to 8000. Now that I can rev the motor higher, when I shift to the next gear my rpms stay up around 5000. The higher the rpm, the more power. To an extent of course. I definately feel a difference!:icon17: I'm glad I had it done. Of course once I get the Stillen S/C for the Z it would have to be retuned again, but who cares!!!:happydance:

How much was the ecu chip?

Glad you like it! It was nice meeting you today...

Let's see the pic of the twins! :rofl2:

I posted it in the "General Discussion" and also in my album!:tup:

nice! I'd like to see how the tune tweaked with the power curve. Do you feel that the car hits peak power at a lower RPM with the tune?

Peak power is toward the high rpm range. Between 7000-8000. The car just pulls all through the rpm range if that's what you mean. Also it feels smoother all the way to 8000 rpm!

The graph of the power curve you seek is here: Technosquare ECU remap

Thanks :tiphat:

How aggressive is the tune? I skimmed over the thread and couldn't really find a clear answer. Any graph with the A/F ratio along side?

LOL that's where I saw the dyno results LOL! Thanks Phimosis! I didn't do the dyno because I have pretty much the same performance mods as killerbee370's and he dyno'd his.

I have a graph of a single run after remap with A/F ratio. didn't scan it. It's not agressive (lean). The agressiveness is in the ignition advance. I think that info is proprietary. (from memory) The a/f runs similar to stock up to around 6,000 rpm. The re-map is around 12.5:1 at 3k rpm and 12.0 at 6k, then dips to around 11.8 at redline vs. the stock tune trending up to a little over 12.0 at redline. So it is rich to keep temperatures down and power increases coming from timing advance.

Nice job on the re-map. Looks like they got the A/F's right where you need them for best power...

Great article on A/F's here: Autospeed article

Just wondering if doing this tune would void my warranty? I'm assuming so.. but hoping not.

Anything you do to a car carries the possiblity and all likelyhood of voiding a warranty. The beauty of a reflashed ECU is that it's just that... a reflash that can be flashed back to stock at any time to retain that clever little thing Nissan calls a warranty! ;)

I didn't want to put it in writing, but let's just say that if I have significant mechanical problems in the future that it may take a few days for my car to make it back to the dealer for repairs....

How's the throttle response below 3k rpm? I wonder if you can get more grunt on the low end. I'll have my exhaust and HFC, but I may keep the stock air boxes. Then anything else to lighten the load for more response like flywheel/clutch and pulley wouldn't have anything to do with ECU tune anyhow.

price and how long it took to tune?

Go to their site for details. There is a contact information so you can let them know exactly what you have.

It's actually kind of nice that our engines run so rich from the factory. Gives you a lot of flexibility to end up with a safe tune that makes good power.

Word:iagree:

I am fairly certain I know the answer to this, but could a Technosquare tune remove a CEL from say, test pipes?

WEll I contacted them by email and I asked them how is it that Nissan Nismo engine is 350hp and is eactly the same thing as the 370 but they can only get between 10 and 12hp stock by stock.

At least they were honest to tell me that they may be able to get the same gain in HP but they need a Nismo car so they can see what changes Nissan did to bring 350hp to the engine compared to 332hp.

They also gave me the price of the reflash which Im not gona discuss here, but I think Im gona wait until they can get the 350hp out of the engine stock.

Didn't the Nismo exhaust help contribute to that number? So the 350hp comes from both Nismo exhaust and tuning? 18hp from both sounds fairly safe...

Thats the part I dont know, if Nissan claims 350hp to just the engine or if is the combination of the exhuast, cause I went to Nissan site to compare the 370 and nismo and theres nothing engine wise. The only difference is the suspension and the tune exahust and the strut bars. I did noticed they raised the rpms to 7500 instead of 7000 like the 370, which thats what Technosquare did by chaning the redline to 8000. But other than that, where is there secret for 18hp extra

My guess is that its a combination of both tuning and the exhaust. Say like 10hp from the exhaust and 8hp from messing with some of the parameters on the ECU like leaning out the fuel mixture a bit or a slight timing change etc.

Well if that the case then the ECU reflash will get you at the same level as the Nismo, after you buy the exhaust, but I want to be sure, before spend the money, cause is a lil pricey for me.

If all you're worried about is making 350hp at the crank like the Nismo thats really easy to do with a few bolt ons like cold air intake + exhaust or other combos of bolt ons.

Would there be any benefit to have my ECU reflashed with out a dyno tune? I noticed you can mail your ECU in with a list of what mods you have on your car, but will this even produce power. I understand that a dyno tune will yeild the maximum gains, but I don't have access to a real tune shop around here. Maybe a drive to chicago, but don't know there either. Would I be wasting $550 to get this done? Thanks for any input. Agian I know that a dyno tune will yeild the best gains.

wat

Well now that you just said the price lol, the reason I find expensive the regular reflash with everything stock is because yes they did have to do a lot of test and programing and changing on the first car to get the gain they did. But Im a computer guy, I kow that after that setting is done, they just save that into their computers or even a flash drive. THat is why they are able to offer you the reflash, just send the ECU, they upload the basic setting, and you get your gain.

So in other words, they already did all the work and that labor got already paid off, $550 for an upload to the computer, nah, something that will take them 10mins. Now if my car is there, and they have to dyno it, change, dyno, change, etc then I understand they need to be paid for the labor.

But that is my opinion, it doesnt mean Im right :)

Engine

Nissan 370Z
VQ37VHR – 3.7-liter DOHC 24-valve V6 aluminum-alloy engine
332 hp @ 7,000 rpm
270 lb-ft @ 5,200 rpm
Bore and stroke – 95.5 x 86.0
Compression ratio – 11:1
Maximum engine speed – 7,500 rpm
Emissions – Tier 2-Bin 5 (Fed); LEV2-ULEV (CA)

Nissan Nismo 370Z
VQ37VHR – 3.7-liter DOHC 24-valve V6 aluminum-alloy engine
350 hp @ 7,400 rpm
276 lb-ft @ 5,200 rpm
Bore and stroke – 95.5 x 86.0
Compression ratio – 11:1
Maximum engine speed – 7,500 rpm
Emissions – Tier 2-Bin 5 (Fed); LEV2-ULEV (CA)

My guess would be that there is also some changes done to the vvel on the Nismo.

The thing is that Nissan doesnt say anything, if they have different head, or diff cam, etc, is just exactly the same settings.

the only things that are different power wise is the ECU tune and the exhaust.

just wait for an agressive ecu tune and cams and people will be making plenty of power.

pretty much the same as much as a evo X, 335i, or a bolt on 300zx twin turbo

Again with the agressive cams eh? Maybe on the exhaust side . . .

:roflpuke2:

Wrong. You can't compare mods when you're talking three boosted cars and one NA car.

Good luck with the cam thing... :ughdance:

Will you please enlight us, BBOY since you seems to be so smart and rude and the same time. Because like you said right now the Evo been boosted from factory and the Z been NA keeps the battle, so what make u think that with a Ecu Tune and some cams, wont do it?

Ummmm...BBoy is correct. It is Very easy to get BIG gains out of Boosted cars with a tune... a simple 3 psi boost is good for 15-20 hp alone on a Turbo car. Many can add 30-40hp+ with an aggressive tune. The tune on my Audi TT took it from 225 to 265 with no issues whatsoever. It is MUCH harder to get gains out of a N/A engine. 10-15 hp Max is about it..

Manny, one of the reasons you're getting slammed a bit is because there is no traditional intake cam on the 370Z.
