As I mentioned in that thread, I got in touch with the US branch of the company who makes UNICHIP...a piggyback ECU mod. Someone, I beleive in the other 98/99 ECU thread, had noticed that they listed all 4th gen Maximas as having a chip available. The guy I talked to said that it was indeed available. Basically, you bring your car in to one of their installers and they custom tune it for you. Kevlo911 pointed out that this is similar to the Greddy e-manage system, which I had never known about before. Emanage is cheaper and you tune it yourself. However, the guy at UNICHIP said that extending the rev limiter was also possible, but would cost more and be somewhat difficult.

He also mentioned that if there was enough interest, they would consider making a generic 4th Gen maxima chip that would be more or less plug and play...no custom dyno tuning needed. I am not sure if this would include the rev limiter or not...I suspect not.

Basically, I just wanted to make people aware of this, and see if there is interest in getting them to produce a generic chip for our cars. I'm afraid my technical knowledge of fuel maps and stuff is not what it should be (which is why I won't be doing emanage) but I am willing to help coordinate this if people are interested.

My plan right now is to see what the SSR intake manifold is like. If it's any good I will get it, or if not I will probably have my stock manifold extrusion honed. Once that and a couple other mods are done I plan to have it custom tuned or buy the generic chip if there is enough interest to get it produced. I'm probably not going to do the MEVI, so I don't think the Rev limiter is really a concern for me.

So what's the deal? Are people interested? Should I talk to Jack about where we need to bring a test vehicle? Are people interested without the rev limiter raise or is that the deal breaker...I'll have to check on whether that oculd be done with a generic chip.

 

Sounds good!

 

Price?1234567890

 

Unichip is not cheap + install and dyno tune time = usually around $1000 for the Accord guys. It'd probably be similar for the Maxima. Plug n play setup w/o dyno tuning would probably be about half that.

 

I would love it, but thats a little too steep for me.

 

i would buy it for the raised red line

 

I would be interested in a plug and play chip for around $500


EDIT: for extended redline of course

 

i would be willing to go into this for $600 max and it has to work for the 1999's as well. i don't think the extended rev limit is needed since i am not getting MEVI and i will get getting the SSR manifold instead

 

Yes, sorry, I should have mentioned. The guy told me that it will vary from installer to installer since they set their own prices, but that it would probably be about $850 for my car. Definitely an expensive chip.

That's why I was thinking that the generic might be a good thing.

What I was wondering is if the upcoming Stillen one that I see mentioned will have the raised rev limiter.

Good feedback though...keep it coming. If enough people respond then I'll get in touch with the dude and try to iron out some details about how much and if raised rev limit is a possibility.

 

""What I was wondering is if the upcoming Stillen one that I see mentioned will have the raised rev limiter""

Can you tell me where the info on the stillen one is?

 

ouch $850 its like we are being punished because our cars are newer? why nissan why. endus i see your also in MA where are you having it done(installed and tuned). 850 is alot but if they can raise the rev limit and bump some horsepower then maybe it will be worth it. you should try to see if your can work out some kinda deal i mean if they could lower it just a tad maybe $650-$700 they maybe more competitive.
i have talked to adam from stillen about the VQ pro a couple of times and from what he tells me it will only be fore newer VQ cars i.e the 3.5's not the 3.0's, he also mention the will do something for the QR25DE motors. i am going to keep on the SSR thing i think that is my only hope if i wanna increase some HP. this unichip seems like its alot of money for unknown results..... more info is needed so see if this thing can do what jim wolf and technosquare can do

 

well im takling to jim wolf right now.and they say that a 96 ecu will work in the 99 maxima with some mods done to it but they did not explain.so i email them back asking what needs to be done.so if they can tune the 96 runline up to 7k + and it still work for 99 im buying it.so ill keep you posted on what i find out

Thank you for your interest in JWT products. Yes it is possible to use the 96 Maxima ECU in a 99, only after it is upgraded though.

If you have any technical questions please give us a call M-F 8-5 (pst) @ 619-442-0680

Ill take it for the $$500-600 range if it raises the limiter if not just for the fact my Stillen S/C is on da mf way..


~we ((99's get the Shafffft))~~~

 

yaw get no love, nissan should have just made yaw 5th gens

j/k


i hope this works out...just something new for maxi's

 

nah someone will figure it out soon. i just want the redline increased on mine. since i will get my supercharger later this year.

 

@Zack - The installer the dude referred me to was Fastline Motorsport whose website is, I beleive, http://www.fastlinemotorsport.com/. Thanks for the info on the Stillen unit...sounds like the UNICHIP may be moer or less the only option now. Hurt!

@Chuckie - That's very interesting. I talked to Technosquare and they basically said there is no hope of a 98/99 ECU, but maybe JWT would do one. It seems like that might even be a better solution than the UNICHIP since it would definitely do everything people want...but where have they been all this time? There are people out there who would be buying their ECU's if they made it for the 98/99 without having to have a CEL. That might be something we should check into further...

 

yeah i spoke with techno also and they said that the 2000 ecu might work in the 99.but they ar still working on cracking the codes for it.so im looking on getting a 200 ecu to try out in my car. and also get me the 96 ecu for jim wolf and try that also.but im just looking for the redline increase. cause ill be boosted soon and only need it for my mevi

 

Endus Unichip looks pretty good i guess. its $425 but the installation kills since it involes dyno tuning and programming but if it can do what the JWT ECU and Technosquare ECU can do then it will be worth it. i am going to call and find out how much it is installed with the raised rev limit. it is also a bit more enticing to me because they are specifically tuning it to MY car so there for i would be getting maximum gains. if you can talk them into developing a geniric plug and play application that would also be great since the cost would exclude the dyno tuning but we can only wait and see.

 

Cool. We def need to call Mr. Connecticut to make sure he can actually raise the rev limit...the guy from the big company said yes, but I'll believe it when I hear it from the dude whose actually doing the install. Let me know what he says.

I agree re: the custom tuning for your car as well. I know there was some rumbling about a someone possibly running lean from the JWT's...I don't think it turned out to be true but the idea of being *extra* careful and making sure that everything is cool in *my* car is why I am willing to pay the extra as well. It's probably a bit silly to some, but I don't know nearly as much about this stuff as I should....learning all the time. I have a tendency to pay through the nose to get it done once, then do it myself the next time...maybe on my next car I'll do eManage.

 

Really? That's wierd. I emailed them not more than a month ago and they said there was no chip for 98/99 and there would be no chip for 98/99....keep us posted on that one!

 

Hey endus i just called Unichip on the # on thie website and the guy told me to hold of a week or two and check back their website since they will be updating it. he also mention that their will be plug and play nissan applications in the works so we will see but as far as this goes $780 for a FULLY dyno tuned system for my car is worth it. i am going to wait until the end of the month to see what develops as far a SSR goes because if they can do a manifold that doesn't deplet the low end then i wouldn't need an extended rev limit but if there just beating around the MEVI here i come. But since i am not a fan of swapping a 2000 ecu or 1996 ecu into my car this is what i am going to do and best of all no down time. i am guessing they can have it installed and tune in a day. i am just waiting to see what fastline says when they call me back...
thanks for the heads up endus

 

Cool! Thanks for checking again...sounds like we just have to wait a few of these things out and see how it develops.

 

if it is similar to the greddy emanage then y not do that and tune it yourself pay a hell of a lot less.

i would only want the extended redline from them but i would not pay 1000 for it.....sorry

 

but what about the 98's

 

yeah i went down there since i work down the street from them they said they are trying to work it out but they dont think they can.and they are pretty sure a 2000 ecu will work for a 99 so i am going to try

 

ill ask them about the 98s next time i talk to jim wolf. im sure the 98s ecu will need to be reprogrammed as well if you use the 96 ecus

 

Hmm older VG maxima applications also

 

Here Is The Update For The 99 Ecus. Yes The 96 Ecu Will Work For The 99s And They Said They Can Program Them Up... Jim Wolf Is The Place To Call .. Im On The Hunt For A 96 Ecu And Send It To Them To See What They Can Do. Im Also Going To Call Technosquare And Ask Them About It Also. So I Will Keep Ya Posted

 

I just ordered a 96 ECU to get reprogrammed to use in my 98. But as far as the 99s go, I thought there was an issue with the vehicle immobilization system. Is this not the case, or is there a certain workaround for this? IIRC, on the G35 forums, guys have to modify their own ECU that matches up with their key with the chip in it; they can't use a spare ECU. I'm sure there may be an easy way around this, but I'm just curious what it is.

 

yeah im not sure where did you order you ecu from. jim wolf siad it will work so we will see im going to order one and fins out

 

Got mine from a junkyard that had it listed on car-part.com from a 96 SE 5 speed manufactured 12/95 for $115 shipped.
