Just recently got my ecu back from technosquare, top end feels great but at low RPM the car feels under powered and hesitates like it's getting too much fuel. You can feel the motor want to go but again the motor stutters at times like its chocking on a shitty a/f mixture until you get into the higher RPM when all hell breaks loose and a smile is put on my face. I've come around corners at 2500-3000rpm and layed on the pedal (WOT) to violently slide the car out side ways and have had the motor just stutter/hesitate leaving me unable to put enough power down to break the rear loose. This is really hard to explain but any insight or direction would be greatly appreciated, I would expect there is something the matter with my tune as $550 has got to get you a better result than this. I've searched the forum and haven't read anything similar to this concerning technosquare's tune's, just looking for some feedback before I start spending more money to correct this problem.

Also, my invoice from technosquare reads;
350z 2005+ ECU upgrade program # EV10A_STG1_V4.... thought there would be a tune for 07-08 specifically....?

 

It’s a one-size-fits-all mail order tune. Maybe your expectations are too high.

 

i would call technosquare?

 

go to zee dynoe my frenddd....real tune ftmfw!

 

should of went with uprev

 

UpRev FTW!!! you need a dyno tune!!

 

EV10A is an ECU number for an 07 350z MT... invoice seems right for the application...

 

I'll check what my invoice says but about your problems, I think the a/f ratio needs to be corrected. I had the same problem as well and to some point even after my custom tune still have it. I've just learned to live with it. You should call them up and see what they say.

 

Damn, this makes me want to reconsider getting a tune. Or would you still recommend it? I love having low end power over high end, hence why I also just bought a 4.08 FD kit.

 

Don't even worry about it, man. This thread is just a case in a canned tune not being right for the end user. With Osiris, you can just send the tuner datalogs and receive updated tunes which you upload yourself. No shipping your entire ECU off and not having a car for a few days.

 

Well Technosquare is close to me so I planned on just going there and getting a dyno tune. How does that compare to Osiris?

 

Howdo people still choose that option with the other options out there for near the same price.

 

What other alternatives do you know aside from UpRev and Technosquare? Those are the only two I know of.

 

In that case then, TS would be a viable option. You can't get a better tune than a custom dyno tune.

On the other hand, if there is an UpRev tuner/dealer near you that can custom tune your car on the dyno, I would go that route, simply because Osiris includes datalogging and diagnostic capabilities and TS does not.

 

You know, there are Osiris Tuners in Socal too...one in Canoga Park and one in Wilmington, not too far from Technosquare

 

.nvm

 

UpRev.... Easy.... Specialty Z fan here

 

+1 Sebastian and Gregg are very knowledagle and good tuners. they Will be taking care of me pretty soon, the 21st to be exact

 

Right...but I have a base model so that means no cruise control buttons. So how am I supposed to switch between maps?

 

^I asked the guys at Church Automotive the same thing, they said they don't know of any other way.

I thought maybe having a CarPC would work, but they didn't understand my question when I mentioned that.
