technosquare anyone???

[gmoney350Z]

does anyone on here used the technosquare ecu reflash??? if so, i have some question i gonna ask you!!! thank you

[bkreitzer]

There is another thread discussing ECM upgrades and reflashes. I am seriously considering allowing technosquare to reflash my '07. I have talked with them about the options and it costs $550 for a vehicle drop-off (in person not mail in).

What year of Z do you have? Have you talked with them?

[gmoney350Z]

I have a 06 Z with alot mods and its auto...I called them on friday and they said it was $750!!!...maybe I heard wrong but if its $550 I can get it by the end of this month...does it if you have manuel or auto for cost to change???...just asking, what Z you have and mods???

[bkreitzer]

I have an appointment with TechnoSquare on 4/10/2008 to reflash my '07 Nismo Z. The only engine mod I have is the Nismo CAI. I do not plan on modifying the engine further as I think the CAI and reflash are all the new engine needs. This is going to cost me $700!!! (550 for the reflash and 150 for the Dyno). This had better be worth it!

I cannot wait to get it back and check the results!!!

I will post before and after dyno results with the CAI.

I do not think that the transmission matters in the cost, but be sure to fill out the information sheet on their website before sending in the ECM.

Their phone number is 310.787.0847

[gmoney350Z]

Oh that's tight bro...ill just get the ecu reflash I really don't care about gettin it dyno...I just need to get it tuned...imma just call them and get more info this week...and keep me posted on the number you get out your nismo Z...and thanks for all the info bro.

[bkreitzer]

Before you reflash your ECM... what mods do you have for your '07??? Most bolt-ons do not add too much power to the older engine, so list your mods and we can go from there... the reflash is a little costly...

I got:-Aem cold air intake-Nismo exhaust with 3' piping with shock Y-pipe-dc headers-kinetix manifold planum-motordyne MREV2 manifold

And that's my 06 350Z

The DE engine will most likely not gain too much from the mods; meaning not too much HP and torque gains, but I imagine that it will behave much better and give consistent fuel/air mixtures throughout the powerband. The ECM in the Z's will NOT know your mods, so to unlock the money, time, and advantages of the mods I would suggest that you proceed with the ECM reflash.

My '07 Z is in today for the upgrade!

[bkreitzer]

Oh, that reminds me... since you are in LA... are you going to the Z West Coast Nationals this month? How about the Stillen Nissan/Infiniti customer appreciation May 17th?

[rmezz13]

i want to know your gains. i'll check back later/ tomorrow. thanks

[gmoney350Z]

I see what your saying well by the end of this month I should have the results and post them up...I may go to both with the shop I go to...are you going?

I'm interested in seeing your gains with intakes only.

[matt_2036]

I have seen a gain to 288 whp with the below gains. This was gefore thehigh flow cats and flywheel/clutch. Hp gains can be made through na build, but it must include a tune!

[gmoney350Z]

I will post it at the end of the month bro!!!

[gmoney350Z]

I will post it up at the end of the month of my 06 Z

I am going to both.

My dyno results!!!!

Date: 4/10/2008Car Specs: 2007 Nismo 350z with the Nismo Dual CAI.Dyno: SuperFlow WinDyn Dyno V2.7, calibrated on 4/2/2008

*NOTE the numbers below are wheel numbers, not top-side numbersGovernor settings=185 (changed from 155)Tach settings=7500 (was not changed)

Before HP=280 RPM=6900 TORQUE=242 RPM=2700After HP=292 (+12) RPM=6900 TORQUE=256 (+14) RPM=2500

The Throttle changes was the change I noticed most on my drive home last night. I feel like it really makes a difference when it is punched esp. at higher speeds.

Also, for some reason that I cannot explain... it is easier to shift smoothly...

Well I may see you there bro!!!

[gmoney350Z]

Man bro I can't wait til I get my ecu reflash...what you think I can get with the mods I have?

[bkreitzer]

Man bro I can't wait til I get my ecu reflash...what you think I can get with the mods I have?

It would be hard to answer that... I would guess you are losing HP and TORQUE right now because the ECM does not know about the parts... so you might get a big jump after the reflash or not... so hard to tell... maybe the results will yield 20 - 40+ RWHP.

Do you have a dyno result from before the mods? You could consider using one from the web as a baseline, but try to find a dyno result generated from a SuperFlow...

[gmoney350Z]

Yeah if I can get 40 more hp ill be good...naw I don't have a baseline dyno...imma just do the before and after dyno with the mods at the end of the month

[rmezz13]

How much did you pay for +12hp and +14 torque ??

[bkreitzer]

$600 with the before and after dyno. The reflash was more than just increasing the HP and Torque. I wanted the governor and throttle settings changed as well.

[rmezz13]

Thats pretty good, i'm looking into the Cobb AccessPORT for mine, looks like its running about $700 if the G35 guys don't get back to me about the group buy. You can change it all your self its a plug and play so you can reflash from the inside of the car, there is on the fly mode changing, and you can adjust your idle, and timing as well. Many things you can do and its not uncommon to get 17+ whp. I figure that would be nice, i could use that to help other Z owners as well. I looked into what you had done and the local guys in columbus never heard of doing that, so i figure my only option is the cobb's accessPort.

Thanks for the info and posting your before and after results.

I was checking those out as well. most of those systems are pretty in depth. using it with a few dyno runs seems neccessary to keep everything in sync. i would love to have different maps saved for economy and sport

I would normally agree with you, but the ECM reflash, for me, actually increases my MPG a little as long as you are light on the throttle. I big question I have is that could a separate set of maps actually "choke" the engine for a true eco mode. Adding 2-5 MPGs would be nice when I am stuck in traffic and cannot "drive" the car.

[rmezz13]

got to the website (google cobb accessport) it says something about changing between modes on the fly, maybe going from sport to economy like when your stuck in traffic..... i think it can do that.
