ECU Upgrade
Are there any real techs that are qualified to answer these obscurities??!!! I dont know about you people but I have a hard time listening and belIeving most other members claiming that they know their sh##&$t!!! PLS IF YOU ARE A QUALIFIED TECH PLS STATE SO...OR STFU!!

It's just I get so pissed when I hear of jackasses we all know who wreck it on the street or freeway in a dumb *** drag.
Or the dumb mods that f..k up our enviornment.
Want a good mod NC guy? Get a SC or turbo.
(NC dude: I apolige for my crack. I was attempting humor.)
We all need to care people. if nothing else 911 told us that.
That being said: NC dude: I'd love to get on a track and waste you.
and if you left me in the dust... well, I'd like that almost much.

The US is one of the few countries that regulate emission. Ever breathe the air in Mexico, or any other developing countries?
Internal combustion engine emits pollution regardless. Get an electric car if you feel otherwise. http://www.itiselectric.com/
Meinser boy, you may want to partake in some liberal weed and chill out. All I said is that I don't think the world at large (ei: you) needs to worry about the barely increased emissions from a miniscule number of 350Z owners who would choose to take their cats off. Having grown up in LA myself, I take no offense to anything that you say...
Go visit a superfund site then yell at the 10 guys on this board that will "hurt" the enviornment with their modified ULEV engines.
You can race an electric golf cart or wait for that hybrid NSX.
Settle down Beavis...

I am not going to get into deails but there is a lot of HP to be gained from ECU tuning
For those who want to remove their cats it seems it does not help this car by much if at all. seems the varible valve timming takes offense to the loss of back pressure. Once the engine tunners figure out how to work with the valves you will see improvments with exhaust mods.

On freeing up HP, pollution, and weather the dealer will know if you changed anything.
The amount of power that you can usually gain from an N/A motor is usually minimal 5-10HP with ECU tuning. But, if this car was deliberately detuned from over 300HP by doing something like making the car agressively pull timing then yes, it is possible that an ECU will show us big gains. There are other instances of this happening on N/A motors. The Audi 4.2 V8 in the A6 platform gains about 25HP with an ECU upgrade because Audi deliberately detuned the motor.
Increased pollution from ECU tuning is possible but not likely. One of the biggest changes you can make in an ECU on a N/A car is advance timing and maybe add a little more fuel if you can flow enough air. These changes aren't going to have much affect on your emissions system.
It generally is possible for the dealer to tell if an ECU has been altered. Even plug-in style ECUs are usually under a cover that is held on by several screws. Dealers will look closely to see if the screws have been tampered with. If they really suspect something they can put the car on their diagnostic equipment and usually find out of spec values in the logs. If say, you moved the rev limiter up 500 RPM they may find instances of you shifting beyond the factor limit and deduce that the ECU has been altered. That said, unless the car starts having a bunch of ECU related problems there's probably little chance that the dealer would ever take steps to figure this out.

Okay, maybe this is coming out of left field (now that we're off the terrorism kick), but I remember reading somewhere one of the easiest ways to tune the ECU is to make sure that its mapped only for your specific fuel. For instance, the stock ECU has to be able to accept 89 octane without knocks, simply because many people will occasionally miss premium, or whatever.
Sport Compact mag showed gains when using 100 octane, but from what I understand, the factory ECU doesn't like that a whole lot either. So I'd guess a new ECU designed specificly for 91 (or 92 you lucky bastards everywhere but california
), a slight piece of power could be grabbed there.
Also, are the rumors of the NISMO chip just complete bs?

They will pull data if they think they can denine a claim.

) and then have my turbos blow my Audi dealer would have an interest in not warrantying the repair. The reason is that if the regional Audi rep were to come inspect my car once the repair was complete but before my car was returned to me and he/she learned that my car was modified but the dealer decided to warranty the repair anyway he would deny the claim and leave the dealer holding the bag on the repairs. Has this ever actually happened? I'm not sure. But, I have seen an actual original copy of a memo sent by Audi to their dealers warning against covering modified cars and that they could be held liable. I had a very cool dealer who was very mod friendly share this info with me. You are obviously one of the cooler techs and I appreciate that. My dad works in the service department of a large dealership that regular services many highly modified cars, including one with a 3 stage nitrous setup. He believes in covering everything on that car that is not broke as a direct result of the mods. The problem us Audi guys have faced is that the dealers have been warned so much that most are very much against mods and will often go to great lenghts to identify modded cars and report them in the Audi database as modded which effectively voids the warranty. For us it took a ton of turbo failures for Audi to adopt this policy. I know the 350 doesn't have turbos but if we start seening transmissions or rear ends or some other major component braking a lot, it may cause Nissan to adopt a similar policy. Don't mean to be an alarmist, just trying to give people a heads up as to the possibly implications of ECU tuning.

u have to chip the s4 hehe. its like night and day i loverd the mtm chip i had on mine. anyways, as im sure u know, u can just buy a whole new ecu with the chip inside. that way u can swap the stock one back in and they wont know. although mine was a bit suspicious due to some higher than normal boost readings (i forgot to reset everything with a vag). i just denied everything and told him to go ahead and check. they couldnt prove anything. hehe
it would be nice to get some good gains from chipping the Z.

Oh right you're from NC. that explains it all. Be sure to kiss your wife...ahem...sister...ahem....wife goodnight tonight.
To all those NC posters who asked previously: Yes! you CAN use your pick axe to "mod" you Z. Strike squarely and out the MF..er comes.
Look NC dude... maybe you belong on the CRX boards???

You are very sad

I'm gonna chip my car regardless. It is a must do mod for me as far as bang for buck goes and here in California when you buy a new car you don't get smogged until 5 years.
So fug em! I bought the car, I'm gonna tweak every bit of HP out of it I can.
Can't wait to here from a repuatble company that puts out a good one. Rev limiter, top speed limiter, cooling fan options, spark, fuel advance etc etc!!
Bring it on!

Nissan wants to get a big piece of the Sports car market. They will do this by getting a rep as selling fast easy to mod cars. If they denie every warrently claim due to a part mod the will soon loose you the youth market. Nissan is not stupid.
My information came from some japanese engineers that worked on my car months ago when my new tranny was put in and partial information from Dutch Doer of NNA he is ahead of all the dealership parts and service departments in the midwest and is helping bring nismo parts to nissan.

LA dude, you obviously have no idea what the f*ck you're taking about. I work for IBM at one of the largest IBM complexes in the world, right here in North Carolina. Research Triangle Park, NC is located between Raleigh, Durham and Chapel Hill, NC and hosts major installations or corporate headquarters for such corporations as IBM, Cisco, RedHat, Nortel, Glaxo-Wellcome, and SAS Institute. Raleigh has NC State, a respected engineering school that had one of the first educational nuclear reactors in the country, and I think you might have heard of Duke University in Durham and UNC in Chapel Hill.
I know that others have made it quite obvious to you that you came off as being the most ignorant f*ck currently lurking this board, but I wanted to take a special moment to inform you that, no matter what you think you learned from the Beverly Hillbillies, there are a large number of sophisticated urbanites in North Carolina who take special offense to your type of bigotry.
I know from first-hand experience that there are some deep-mountain folks in North Carolina that are complete bumpkins, but I would bet everything I own that they're smarter and saner than some of the....interesting specimens that you have running around in the deep recesses of California.
California doesn't hold a patent on sophistication. Get used to it.
