Is there a speed limiter on the Eclipse's ECU, and if there is where could I get a chip to remove it and around how much horse power would i get from that.</P>


What other chip is there to add up more horse power.</P>


</P>

 

It depends on if you have a GST or GSX<FONT color=black>. The non-turbos don't have a governer, and neither do the GSX's. Only The GST's have a Speed limiter. You won't get ANY horsepower from removing the speed limiter, it will only allow your car to reach a higher speed. There really aren't any chips that really work....there all mostly marketing scams. Some will do what they're stated....but not in the way you're thinking. </FONT></P>


<FONT color=black>No chip ever really helps, or any other wonder mod for that matter. Think of it like this, if the chip is really that good, wouldn't the manufacturer have put it or something like iton the car originally? In a very competetive market like this whereefficiencyand hp(now anyways) are the key to selling their products, the manufacturer would try and squeeze every bit of performance froman engine before they sold it. So why not "chip" it beforethey sellit? </P>


There was a test done on the venom chip that made an astounding discovery. The chip claimed increase hp and torque by about 20% except at full throttle. Well, it did. However, it did it in a very sneaky and undermining way. Instead of "optimizing" the engine's fuel maps or what not, it simply intercepted to throttle signal and modified it. So if you push down on the gas pedal about 50%, The "chip" tells the ecu that you're pushing down 60%. When you press down to 85% the ecu thinks your at full throttle, so anything above that won't evenmatter to the ecu. So they weren't lying....but they didn't really help your car any more than you could by mashing the pedal a little more. </P>

True I would be worried of purchasing a 20hp chip or something like that but I mean like an engine management ECU/chip like that would give the engine it's full potential with fuel management, rev limiter, speed limiteretc...</P>


For instancetheR34 is set to 280 hp from the manufacturer. Why? cause it's the law for all manufacturer in japan or else the would a horse power war. I'd like that. I mean a skyline engine could hold around 1000ho. So what would happen ifNissan sold the car with a 1000 hp engine <IMG src=smileys/smiley15.gif border="0">.</P>


I dont know, the R34 sold has a 280 hp engine, but limited it's actual full potential is 350 with just a 200 chip to unblock the limit set by the manufacturer.</P>


Other than that usual they dont produce a car to it's full potential for an other reason to make money like Nismo among others. If they did a lot of companies wouldnt have a reason to be.</P>


Anyways thanks for the speed limiter.</P>


Whatwould be a cheap good engine managment that has it all for the GS-T</P>


</P>

 

Greddy emanage is a good piggyback system that gives good control. Absolute control would be a dsmlink, but only for a 2g. TMO makes speedlimit and rev limit chips for 1g's. There are absolutely <U>no chips</U> that work with 2g cars. I think it has to do with the OBD2 system.</P>


For the skyline comment, The GentleMen's Agreementon HPin Japan was made to help with the discrepancies in production cars and their racing homologizations. Manufacturers weren't allowed to sell the production cars with all the same equipment as their racing equivalent. So they all agreed to limit the hp since that was the easiest thing to control. Atleast, that's what they say. Now be reasonable, skylines are capable of 1000hp just like any other engine. You can build a 1000hp corolla engine if you like. Nissan wouldn't spend an exponetial amount of money to build a 1000hp skyline and sell it for nothing under a million dollars. Horsepower isn't cheap, especially after the 500hp mark. Remember,by your example,Mosler and Saleenwould be in a constant hp war.The r34, or r33, or even godzilla r32 can go up to 350hp with the stock turbos, but a simple chip won't bring out the full potential. Opening up the breathing and raising boost will bring it closer to 350hp. A fuel management chip and speedlimiter just won't cut it....You probably might not even need to do any fuel mods to get to the 350hp mark on those engines. Chips rarely ever do what they say, unless you're in a diesel....then you're in luck.<IMG src=smileys/smiley2.gif border="0"></P>

 

Agreed about the skyline, and about boosting it up to 350hp that is obviously thefastest way of getting to 350 but still that isnt it's full potential. The R34 OFFICIALLY comes out from the manufacturer with a block on the ECU, to unblock it u simply get a chip that costs around 100$ to 200$ who's fuction is to unblock that blockage inECU. That is a fact. I mean I'm majoring in computer science, it's like having a program (in the ECU)and simply just with a couple of words u could minimise or maximizethe output of the programdepending on how u program it. Obviously with a boost and that chip it will go up to around 420 if not more with no kind of upgrades. I mean it's a 2.6 TT engine that could hold 420hp without modifying it. 2.6!!!! </P>


About the 1000 hp true most 6cyl TT have potential to get there, and other 6cyl would have to have space for a TT set up to start the 1000hp project. So why do u think the R34 is so intimidating to it's adversary, it just has a 2.6L engine. That could hold up to 1000hp. It's such a tiny lookingengine compared to other 6 cyl like the Zs and the supras. but at the end size doesnt matter.</P>


I was thinking of getting the Greddy E-Management but what functions does it have other than fuel management, and if it did add horse power how much would it add. And can the E-management be controled by on/off switches.</P>


How about jet chip are they good or not really.</P>

 

<FONT size=1>Perhaps the ECU has a block, but it doesn't have one to limit HP. Only Speed, rev limit,andboost pressure, which contribute to limiting hp. Understand that these ECU's are ROM type chips, They are for the most part static controls. To absolutely limit HP, you need to limit the fuel maps, mostly. If Nissan limited the fuel maps, they would definitely not be able to produce the kind of power that the engines do. Instead they limit boost and that limits HP. However, almost every turbo engine has limits on the amount boost they can run. Modifing the ECU isn't the "fastest" way to get power, slapping on a bigger turbo is<IMG src=smileys/smiley2.gif border="0">. Plenty DSM guyshave added another 75hp by putting on a 16g and they'd never even mess with an SAFC, much less the ECU.</FONT></P>


<FONT size=1>As opposed to the small size of the RB26DETT, i'd say the R34 is is revered for it's ability to rev higher because of it's undersqaure design. Also, the "car" has a major part in it's reputation. It comes in a light-weight(relatively) AWD(rear biased) package. Not very many cars come with a rear biased AWD system. Audi Quattro's and DSM's are primarily Front drive cars that have been converted to AWD. The Skyline is a rwd car converted to AWD. Because of this, it is more set up for any type of racing or motorsports. Also, the engine is bullet proof. You can add any amount of boost to an engine, but the manufacturer buildspecs are what count in the long run. Most of Toyota's engines were designed by Yamaha, just because they have a reputation of building solid engines that can take abuse. Nissan followed Yamaha's idea and "overbuilt" their SR20, VG30, and RB26 engines. That's the main reason enthusiasts like the Supra's, 3SGTE Celica's, Skylines, and so on. Wouldn't you like to have an engine that you know is really hard to break? Unlike a Honda engine where precision is key and pushing it past 300hp makes the con-rods go out, you have to maybe push the2jzor rb26 to like 650hp beforeopeningup the bottom end. As for the undersqaure comment, That allows it to rev higher. And we all know that the higher an engine can rev, the larger a turbo it could potentially run. Now just remember that you'll never see a 350hp skyline with a stock intake or exhaust sytem! These are ways nissan used to limit output on the engine. Close up the breathing a little and the engine won't put out as much as it could. Sorry if it seems like i'm being a jerk, i don't wanna come off sounding too bad, but chips aren't the key to unleashing an engines full potential. If they were, we wouldn't have an aftermarket this big. You've let the hype get to you, especially the "chip" hype. Chips, or rather piggybacks now, can do a lot of things tofree uppower, But since the introduction of OBD2, chips can't really do all they claim. Piggybacks still work, but they are an external control.</FONT></P>


<FONT size=1>As for the Greddy, it has 16x16 fuel map controls. It can control Ignition and timing to an extent, and can be a boost controller and turbo timer. Also, it can be a datalogger. Understand that these chips and piggybacks don't "add" hp in a sense, they fine tune the engine release the potential of the engine. I'm not a big fan of Jet though....a lot of choppy gauges and semi-false marketing....</FONT></P>


<FONT size=1>You're a CS guy? I'm on my third year in EE over here at University of Cincinnati's College of Engineering. What college do you go to? You're not in Lebenon Ohio are you??? If you are, we should hook up sometime.</FONT></P>

 

EE u shouldve went for ME. Thant's some good info u got, thanks.</P>


but for the chips why did they get that much of a reputation, I mean they should have something in them that works for the market they have.</P>


Ok with 2000$ from a stockGS-T what do u think i should get</P>


hehe Beirut Lebanon at Notre Dame University..NDU....</P><edited><editID>slayeroger</editID><editDate>38085.9464236111</editDate></edited>

 

My dad's an EE sooo....you can guess the rest. </P>


Chips don't really have a reputation, the marketing meks it seem popular but it really isn't. All they rely on is marketing to really get sold. They haven't really received good reviews, but they try and make it seem like they do. Now, with $2k, you can get a gst into the twelves....without chips<IMG src=smileys/smiley2.gif border="0"></P>


NDU huh.....<FONT size=4>GO BEARCATS</FONT><FONT size=5>!!!!</FONT> Well they didn't make it to the final four, but they went far enough for me!!!</P>

 

Oh, for mods, go with an Fmic, upgraded injectors and fuel pump, fuel management(SAFC, or even GM MAF/MAFT), and then get the biggest turbo you can afford after that. I'm assuming you've already got the basic mods.If not, get 'em! They are Intake and Exhaust,and other basic stuff like wastegate and BOV.

 

Ya I see whatu're saying. For fuel injector what do u think I should get, like I mean 750,550,1000cc, or it wouldnt make a difference. Oh and what is 'Fmic'.</P>


Well from the stock set up of my GST(well actually with a green filter, a catalyst taken out and a bit of boost) I was thinking of getting the greddy 24R intercooler kit, greddy BOV, and the greddy upper and lower IC pipes, a stainless steal intake pipe with an A'pexi air filter and a dual stage boost controller, with a custom made exaust system. I was thinking of fuel mods but I'm not sure what to get yet. I mean if I'm gonna be spending 2000$ maybe even more <IMG src=smileys/smiley4.gif border="0">(hopefully<IMG src=smileys/smiley19.gif border="0">) I wanna make sure I'm getting the best parts for my car, thats whyI'm taking time in choosing what to get and asking a lot of questions <IMG src=smileys/smiley5.gif border="0">.</P>


It would be really helpfull if i could get ur opinion of what I'm getting and what i could get. (Wastegate<IMG src=smileys/smiley5.gif border="0">, i though I could bypass it till later on if i dont really need it, would it bother not changing it for the time beeing cause they're pretty expensive)</P><edited><editID>slayeroger</editID><editDate>38088.5031944444</editDate></edited>
