I'm very interested in getting this upgrade, I spoke to the
Japanese fellow who did the programming and he sounds on the ball.
Who has performed this upgrade?
Feedback please.......

I WANT this mod....need feedback....

It's a good mod.. There are different alternatives.

 

...alternatives to an ECU upgrade, or companies other than Technosquare?

 

I think he means tuning alternatives like safcII, vafcII, emanage Ultimate, etc. But you can also choose to get the L spec flash from TS if you plan on doing your own a/f tuning with an afc.

 

The words have been stripped from my mouth

 

Hmmmmm...
I don't plan on doing and additional binary programmimg.
Just want to get the eprom flash.
What gains are to be expected?
Has anyone else had this mod?
Were they pleased with it?
It is soposeto raise the redline to 7,100RPM and remap fuel+O2 over a broad spectrum.

 

The only 6th gens with the mod are the ones who were testers I believe. A generic flash generally doesnt work as well as having the car tuned because different mods result in a different a/f ratio. When u put a car on a dyno you get a readout of a/f and can add/subtract fuel where needed to get the ideal a/f ratio for maximum power.

 

I have the TS flashed ECU, and I am one of the testors. I know there were a few others who had this done after we tested.

The TS ECU can be tuned to your specifications, ie. mods you have. I don't know the gain in hard number since no one has dynoed ECU only, +15 HP and +10 TQ are only estimates. It does open the throttle all the way when you WOT, and car pulls harder from low RPM and doesn't taper off until near redline. The transmission is also more responsive; quicker up and down shifts (no modifications to transmission control module). The rev limiter is raised to 7100 RPM and speed limiter is removed.

If you plan to add more mods after, you either would need a reflash or one of the piggyback systems.

 

So what do they change? I never understood this concept. They should ask for an A/F rather than a mod list. And what do tehy do when they 'retune' your ECU, what are they changing? Timing? How do they know how the 'mod' affected this paramter? If all they change is A/F.. this can be done with an AFC, no down time, perhaps less $$$.

I asked for 7200 and all I can get on the dyno is 7050. Have any of you A34 guys tested this?

They told me they couldn't do anything for this, as it's controlled by the TCM.


Again, refer to section 1 of my post..

 

I'm the very first tester for TS, and I gained 17HP and 10TQ with just an intake installed..

he played alot with the timing on the engine to achive those numbers, I also kept sending it back and asking for more lol..

 

my rpms are at 7100 also and it does all 7100 of them..

 

If you're going by the tach, might as well let a 3 year old tell you what RPM your engine is at.

I'm talking about the data taken at the dyno.

IIRC I have some of your run files... I'll need to check them for that.


**EDIT just checked your runfiles, and you see 7030 MAX. Could it be the sampling rate of the dyno?

 

HAHAHA.... I just checked my run files bro, I'm not like other new orgers..

 

What was MAX?

 

I thought you know all this stuff! They do prefer that you send them AFR rather than a mod list. With AFR, they don't have to guess what you need where. Unlike 350Z's or G35's, where they have several samples with different mods, they can map from your mod list. If or when they have enough samples of 5.5 or 6th gens, you won't need to send AFR sheet. But even then I'd still send with AFR.

As for the transmission, it does have it's own ECU. But the flashed main ECU let the redundancy and value check be done by the trans ECU directly. If you want more accurate details, you'd have to call Tadashi.

 

my numbers are at max, yes..

 

I was asking what were your max RPMs?

 

we started at 3k all the way to 7060rpm on 3rd gear..

 

Which run was that data taken from(7060)?


Mine must be then.. I only see 7060 and asked for 7200... Could be the dyno sampling rate, but even when I was stock at the same dyno, I'd see 6550.

 

that was my last run with the ecu program, the latest one..

 

Tek

After all is said and done, and i know u and Deus have prolly the highest rated ECUs here. How has the mileage been affected? I know after the ECU ur car dumps a lot more gas during the powerband. But how has it been since u got it done?

I drive my car at work, daily... LOTS, how would my mileage be affected?

Kam

 

i dont know if this question was asked before, and i know the answer is probably no, but lets say i get the tecnosquare reflash and i take my car for service, if they flash my ecu or disconnect my battery will that have any effect on the reprogram?

 

it only dumps alot of fuel after 3k rpms, you can drive about 90mph before you pass the 3k mark, so you are ok..

with fuel I can't give you a accurate answer since I drive on 22's, the wheels alone drop my mpg some, but RH told me that his car dropped alittle on it, not enough to complain about..

 

not at all... remember that they reprogram the ecu, the ecu knows nothing else but the new set up, after the tune the ecu doesn't know to go back to stock, infact the program is now the new stock form..

 

I dont see why it would effect gas mileage unless you were flooring it all the time. Other than that normal city driving should be controlled in closed loop up until a certain amount of throttle is reached.

 

Am I reading this correctly that Tek-Niq gained 17HP with CAI and ECU combined? It would translate to less than 10 hp for ECU mod. I suspect that most of the gain is from having the throttle fully open at WOT, allowing more air, and leaning the very rich a/f mix.

 

What's your A/F on your latest dyno?

 

no, I gained 12 with the intake alone, next dyno was with the ecu and intake where I gained another 17hp on top of that..

so 29 total hp with this set up..

 

it goes from 14.5 to 13.1 at higher rpms, I wanna still do some adjustments at lower rpms with the fuel..

I'll probably look into the e-manage or that SAFC cause I have to send it back every time and its costly..

 

After I get back from my trip, I'll go see Tadashi again about any improvements up top. Piggyback would probably be better for you since you will be able to have a couple of different settings stored. One to save you a little fuel, and one for not saving any.

As far as MPG, maybe 10 miles less per tank average on stock wheels. With y-pipe, seems to be almost stock. I'll have to give it more time to know for sure since it's getting hot.

 

reason for the piggyback is cause I'm still alittle lean on the low end, thats where the 14.5 comes in, I wanna get it so right after 3K I get all the fuel so the low end is better, I wanna get the most out of these headers when i get them..

 

So with SAFCII and the ECU L spec tune, you can adjust all the nifty times?

That tuning box, can you have different tunning presets? And how many?

Wow. I guess the Technosquare upgrade is worth the price. Thanks.

Chernmax, you had this APEXI thing installed. Was it difficult? I'm hoping that when TEK installs his he'll take some step by step pics???

I wonder what it will do to TEK ride along with the TS ECU upgrade?

You splice into 5 wires and cut one to intercept the MAF signal.

Search is your friend.

Yes search..... but thats for a VQ35 from a 5.5gen, im not familiar enough with that car so I dont know if the ECU has the same pinout as the 6th gen. If it does.... Thanks for the help but picstures still tell 1000 times better story then a diagram.

Kamski

 

The point was that you can look up the corresponding pin-outs for a 6th Gen ECM and do the same thing.

Besides, pics of spliced and cut wires wouldn't do you any good anyway.

 

yea thats whwat i figured, i had to double check though...thanks

 

The pin out is different I believe. Search altimas.net for Velicos's vafcII wiring diagram. Thats what my friend used to wire mine up.
