I don't have quite the cash flow that I wish I had for my car, but I have saved up enough money to get the Technosquare ECU, which I have been wanting for quite some time. However, I was just reading some of the group deal threads and saw that Cattman has new headers. This will probably be my last mod, at least for a year and a half. Should I get the ECU or save up for another two or three months and get the headers?

 

Could you tell me more about this ECU?? Maybe a website link where they have it for sale? Does it actually increase HP??

 

headers, especially b/c you are an 03... ive heard those ecu's arent worth the $$$

 

definitely headers...are you automatic or 6spd? i've read automatic TS ECU doesn't do much in terms of power...the only benefit is the extended rev limiter...the a/f curve isn't well suited for our cars...becuz its a generic map...and alot of our cars vary

 

I am in an automatic. Extended rev limiter being the only thing? It doesn't change the shift points so it doesn't really affect that aspect. I was looking more at the drive by wire adjustment, timing, and A/F ratio. It shouldn't be generic because it is customized for what modifications you have on the car. Could you be thinking of the JWT being generic?

 

its still generic regardless...if you put mods on my car...and mods on your car...and we both dyno at the same time...i am PRETTY POSITIVE our a/f ratios and timing curves will be both different...TS ECU uses a generic map

u can order the L spec ecu with only the extended rev limiter, dbw adjustment....F spec ecus add in timing/af ratio

 

do you have stuff done to the car or is it mostly stock?????,.. IMO the ecu would be a thing done last after you have headers and whatever else you want to do,

my vote is for the headers, check the stickes, headers and 5.5 FTW

 

headers and 5.5 gens match very well

throw on a GAB for free...gain even more hp...smoke the new civic si all day

 

I've got the Berk Intake w/ Apexi filter, Cattman exhaust from the Y, CatConv, all the way back. It would be nice to have the headers Cattman also, but I would need to come up with at least another $300 to cover install and shipping. With my wife quitting her job to have our twins on the way, it will be hard to explain the money to her. That's why this will probably be the last mod for quite some time.

 

Headers > ECU ...

 

I wouldn't buy the ecu, save up and get the headers.

 

IIRC, all the DBW adjustment does is enables the throttle plate to open all the way at 100% throttle, because the stock ECU does not open it all the way. The F-spec flash is "generic" in that you tell TS what mods you have and if possible, send them a dyno, and they will provide you an AF map that they think is best suited for that. Base timing can only be done using the Consult II, and not via a reflash or piggyback.

What we've seen on these cars is that the AFR looks very different from car to car, even with the same mods, so you'd actually be better off with a piggyback and a dyno or wideband tune over a reflash. Unless of course you get the L-spec and a piggyback, as already mentioned, so that you have the increased rev limiter and DBW adjustment. Another thing to think about is the Emanage Ultimate, but I'm not going to get into that here, plenty of info already out there.

Get headers first....

 

Okay, I've got it. Just how loud should I expect this car to be with these headers?
And NMexMax, do you know of a pretty good shop southeast of you to install these? I will be in Clovis, NM by the time I get the dough for this.

 

Seeing that you have a Cattman cat-back, it will be significantly louder than what you have now.

This is what I posted some time ago based on my experience:

Only other thing to consider is the a/f is typically rich after the headers. You will have to get the ts or tune with some form of afc to really get the most out of the headers.

 

Wow, so basically it would be the loudest setup that you've had. Not too good for me.

 

I just got back from the shop and after several dyno runs I am running super lean. I'm talking 15.5 to 16.0 lean. Why wouldn't headers make it even leaner if it is allowing more air to flow through. Wouldn't headers lean it out even further?

 

Where were your a/f readings taken from? Were they taken from the tailsniffer? If so that could be the 'problem' since the accuracy of the readings isn't as good as it should be.

Also, that is dangerously lean, so I would say it was more reading error rather than actual useable data.

My a/f curves were lean whenever I used an intake, but were right on par with the 02/03 rich @ 5K+ curve so many have seen.

 

Brother I feel your pain... I have a mortgage, car payments, 2 kids, 2 dogs, college savings, retirement savings, assorted bills, and other expenses, mods are always at the bottom of list.

 

I am not too knowledgable on dynos, but they didn't hook anything up to the rear of the car. They clipped a couple of things up in the engine compartment and some device in the cockpit. It is the most reputable shop in Charleston. I am not sure though. They were very surprised about it and said that it was probably because of the intake.

 

Unless you have an o2 bung in your y-pipe, I would say it was the tailsniffer.

 

So Puppetmaster is this a Sexy noise or very annoying noise (The setup you have now)? I am thinking of purchasing Cattman Headers. I already have Cattman Y-pipe, FastCat, B-pipe and Muffler. Will this be a better setup than buying Stillen Headers to join the Cattman B-pipe to Muffler? What would you say your HP increase is sense the install of the Headers (alone)?

 

I would sell the Catback, put the stock catback back on and get the headers. The stock muffler isn't that restrictive and does a good job of keeping the sound down. A B-pipe adds some power and is pretty cheap. You should be able to install that yourself.

I have headers and a B-pipe with the stock muffler and it sounds really quiet. Cruising at a steady a RPM it's silent with no drone at all. It's louder under hard exceleration but not too loud. During regular easy driving most people would think it was stock. I don't like loud street cars at all and this setup is fine with me.

 

why wouldn't you finish modding your car before getting this 'ecu' that is adjusted according to your mods if that's what you say
i don't understand these comments... they're in totally different classes
200hp for a 2liter @ around $22

 

I've got just over $700. If I wanted to save up for the headers, it would take me at least seven to eight months for the extra $300+ I need for the headers and install. If I got that, I wouldn't get the ECU for another year and a half at least. The reason the money is so slow is listed above. If I can get the headers later on (which would still be hard to explain) I can get the ECU reflashed for $150 which isn't too bad. IMO

 

Stay away from stillen headers unless you like spending money on a mod that will lose power in some rpms bands and barely gain anything in most. Either get cattman or hotshot (if you can find them). Stay away from ss autochrome and stone mountain crap as well.

 

Hey Chris, I think you heard my car a long time ago at Corey's house. Just before y'all headed over to the body shop to get your bumper done. I showed up there with Josh (Irish44J). You were with a 6th Gen, but I can't remember his name. IMO, Cattman headers plus Cattman rear sounds really good, but it is loud from inside the cabin. My current set-up is perfect: Cattman headers plus Frankencar cat-back. Its too bad Frankencar is done making anything for Maximas, they had some great products. Basically, it will sound better than what you have now, but louder, and of course, you will get way more power.

As for gains, I need to get the car dynoed, but I'm not sure when that will be.

And like Sloppy said, DO NOT get Stillen headers (there is a whole thread with details on that in the FAQs). They won't give you much. Get Cattman or Hotshot.

 

from who?


Get the headers before you get the ECU, if you even decide to get the ECU, get the L-spec.



I have the same set-up, and it's great.

 

Technosquare does re-flash for $150
What's the L-Spec?

 

It was mentioned in post #6.

 

This is news to me... Got a link? That's not what I paid.

 

My own thread, thanks

about halfway down. It applies to any new mods.

 

$530 shipped for Full spec, $345 + shipping = L-spec is what's needed to spend initially.





I'd rather control my own A/F.

 

How do you find out about the different specs? I thought I've been all over their website.
