Got my Zed back at the weekend after having my Uni-chip re-mapped and what a difference. It felt a bit under powered recently so I got the map checked out. It was running a bit too rich. Running very Smoooottthhh now!!

 

I can't understand why anyone else on the forum doesn't have this chip. It seems to go like the clappers. The readout when it was on the rolling road said that it is pushing out about 370 - 380 BHP at the flywheel. Is this good for a zed that has just had the chip, exhaust and intake done???. Am I still the only one with this Chip on a ZED??

 

I had the PTU changed aswell ( supplied by Vijay via his brother, Cheerz M8!!) so thats one less thing to go wrong in the furture!.

I will try to get as much use as I can out of it now the summer is on it's way. Enjoy the ride guys!!!!!!!

I do know of one other guy with the UNI-chip and he's having it rolling road tuned on Friday so i'll let you know the results as he's done the same mods as you have.

 

I know one thing for sure i am definately the only car(let alone ZED) to have the AUTRONICS management system on my car and it's the dogs danglies!!!

 

Paul

 

I think the reason why no one has this is there are no people reputable enough to get it mapped. (well at least thats the concensus)

 

It sounds about right depending on what boost you are running?

 

Who did the remapping ? I presume they would have used a Dastek dyno (Unichip own them or vice versa) and I wanted to get before and after comparisons for my auto/manual upgrade on the same type of dyno.

Quite right on that one Wazzer, it would depend on the individual mapping the chip. I thought that seemed quite a healthy BHP for the mods made. Would like to crack the 400BHP figure though. What should be the next thing I should look at to give a little more??.

 

Great I am not the only one, let us know how your M8 gets on greddy. I am sure he will enjoy the ride home!!!!

 

Andy, Millway sport does all the work on the car and are an agent for dastek. Very helpful firm with good service.

 

Can't wait to get home now from work to take it for another spin!!

 

Seez ya

Paul,

 

Any info on the ECU you have???

Would be greatful, I have used the Lumenitions ECU before on another car, but they never worked very well on any Turbo car.

 

The PECTEL systems are very good, but quite expensive.

 

Thanks,

 

Leigh.

I have had lumenition before on my racing MINI turbo and worked very well, Have a look at www.gdasportscars.co.uk this is the place that did the work on my 300zx,his name is Graham and he owns the firm and also is the only dealer of Autronics in England!!

 

BTW also check out thread on the board called "HOW MUCH" we are having a discussion about management systems.....To be quite honest, i've looked at all the websites and seen all the info on these systems,none of them seem to offer what the Autronics does in one completely upgradable package....You can have the system with all the goodies that the other systems offer for a much better price and it also supports Water injection,MAP sensors,etc etc etc the list goes on.

I can't seem to find the Autronics website but maybe it's just my PC playing up!!!

My uni-chip can be re-mapped as you upgrade parts on the car and will also support water injection and other stuff. Do you have an idea Greddy how much of a performance gain the Autronics gave your Zed? It sounds very good from what you have said. What other mods have you made to the car?

The performance gain hasn't actually been measured yet because it's only just been run in. The system allows you to gain as much as possible from each mod and set the fuelling and timing and boost pressure for every 250rpm so peak performance is always achieved.When i say it supports Water Injection i mean it controls the management of the water injection pumps so you only have to fork out for the pumps themselves rather than the brain to control it all.i'll keep you posted as things progress.

 

With regards to mods:

JE pistons,ported head,Greddy Max extreme exhaust and frontpipes(no CATS),Greddy profecB boost controller,lightened and balanced flywheel,crank and conrods,Helix full plate composite clutch(specially made),Twin HKS air filters,No MAS sensor(MAP sensors instead,550cc nismo injectors,water injection,FSE power boost valve,Autronics engine management system,launch control,traction control,250psi Bosch fuel pump,twin dumpvalve system,samco hoses,2 GREDDY EGT guages and Greddy boost guage,running 16psi at the moment but will be 22psi in a week or so.

 

Paul

 

 

Jeeeez M8, that is an impressive list of mods. Keep us informed when you get it up to 22 PSI. Your car should be kicking some serious ass if it's up at that level!!!.

I may go for larger injectors next when I have some spare cash.

Greddy, how do you get along with the Profec boost controller? Is it easy to setup?

Simon,

The Nismo injectors are known for making the tickover a tad lumpy as they are soooooo fookin large they run at less than 1/2% total capacity and shut down momentarily only to jump back into life with a bit of a purge causing a lumpy feel.This isn't a problem but just to let you know!!

 

John the Profec B is a piece of piss but doesn't have Fuzzy Logic (i don't need it cos of the Autronics it does it all for me,another advantage!!!).It has a low/high boost switch so you can choose between the two and knobs...ooooh er missus....to set the boost on each setting i.e one knob for high boost setting,one knob for low boost setting and once low and high are set you just switch between the two at will....Simple as that.

Fuzzy logic,just in case you didn't know,learns your car's boost curve so therefore avoids big boost spikes and avoiding detonation/pinking,giving jou a much more controlled and constant boost and a more powerful feel to the car.

 

Paul

So Greddy tell me what turbos you got, or are keeping those as secret!

I'm not at the moment and yes i know i should be but just didn't have the money!!!!

Will be getting the Greddy TD05 kit in the summer and will be able to run even more boost then!!! ha ha all ferraris beware the Greddy is here!!!

i was thinking of buying SE new hybrid T28 stage 3 kit,good for approx 2BAR but have yet to hear any reviews on this product....Obviously i wont get SE to fit them don't worry about that!!!

 

Paul

 

Greddy, are the low and high boost settings, the lower and upper limits that the controller will work within or are they somethign different? Sorry to sound dim, but that's because I am when it comes to electronics and cars. I know that I need a boost controller to use the extra psi that my other upgrades provide but I am not sure whether to go for a Profec B or an HKS EVC IV. I have read the web sites for all the controllers and they just make my head spin and I am getting more than a little confused with all the technology.

Thanks

John,What it does is allow you to basically set the boost at two seperate settings as you wish to set it i.e 8psi for low boost and 16psi for high,but you can adjust these settings for each,low and high,as you wish and then switch between the two pre-sets at will.

Eg you've been tootling around town tearing up old grannies in their fiestas on low boost and you pull up to a set of lights and next to you comes a 355F1 Berlinetta....Press the switch to change to high boost and you now are running 16psi. Simple as that!!!

The settings are limited to whatever your chip/MAP will allow and not to what the controller limits you to, all the controller allows you to do is have settings "pre-set" and you can adjust them at will and it also makes running higher settings safer with the addition of the boost curve learning ability of the controller!!! Breathe..Sorry to go on but that's the best way i can explain it.

If anyone else wants to add their 2pence worth please feel free.

 

Paul

 

 

Ok now life gets complicated. How do you know what to make the low and high settings so as not to damage the engine? The new ECU, turbos and injectors must all work into soem sort of psi limits but how do I know what they are? Sorry again I'm not very technical.

 

Also can the boost controller take an external feed as a signal to go to high boost? As the car is an auto the power setting on the gearbox has a warnign lamp on the dash and I was thinking that if a feed wire could be taken off that circuit then it could be used to change the boost controller from low to high as the power light goes on. I have seen the HKS EVC IV and Profec B both have overtake/boost switch buttons as optional accessories that can be added to the steering wheel, and I assuming that they must wire in to the controller in some way?

 

Sorry to go on, but this is going to be my last big upgrade to the car and I want to get it right so that it brings all of the other stuff done together into a reasonably good package.

John,I KNEW you were gonna ask that!!!!

have you already had the chip,turbos and injectors fitted?

If not then your best bet is to have them all done at the same time, as the standard chip may not be able to provide the right settings for the injectors and at the right boost pressure!

 

If you tell me where you are based in the country i'll be able to point you in the right direction with regards to a specialist tuner for help.Sorry i can't help anymore but i may know a man who can!!!

 

Paul

Yes they are all fitted now. JWT Sport 500 turbos, JWT ECU and 555 Injectors but no boost jets fitted as they made the engine run very badly.

Its just that I have been offered a Greddy Profec B and remote switch for £475 and an HKS EVC IV and remote switch for £575 and now I just have to find out which is best to match my lack of knowledge/ability and the upgrades done. I am based in the Midlands. Thanks I really appreciate your time answering all my dumb questions.

Hello mate,

 

Like your side skirts, where did you get them from and how much, also how much do Uni-Chips sell for?

 

All the Best,

Paul,

 

what turbo's are you using? Apart from your management system, you mods are very similar to mine

 

What's your oil consumption like with the JE pistons and do you find the piston slap annoying until they have warmed up?

 

Steve

Steve,

I havn't actually noticed any real increase in oil consumption but thanks for the heads up on that i'll carry some spare oil with me in future!!

As for piston slap,again,i havn't noticed any but thanks again i'll keep my ears open.It may well be that i've only done 1800 miles on the new engine so these things havn't come out yet??!!

 

I'm still running T25standard turbos at the moment...didn't have enough money to buy new upgraded ones at the time...i'm looking at the Greddy TD05 kit or maybe even the JWT units but havn't properly looked into this yet so Steve if you have any advice on this please feel free to say!!??

 

Paul

Hi Mark

 

My Zed has got a full strosek body kit. It was supplied by the zed centre. It is not exactly the easiest of kits to install. Requires a considerable amount of blending into the bodywork by a professional bodyshop.

 

I did install the kit on the car myself. Fitted the front and back bumpers, the side skirts and the vented rear arch. Saved quite a lot of money doing this and it took about two - three days to install. I have had no previous experience doing this type of thing. So after a couple of days, lots of panel bond and rivots later it went to a local body shop. They then spent 2 solid weeks belnding the kit in to the existing panels and gave it a full bare metal re-spray. The kit has now been on for just under two years and is still looking fine. Going from memory the cost of the kit was about £1900.00 and the body shop charged me £1700.00 to do the bodyworks / re-spray.

Costly stuff but it does look the biz!!

 

Vijay recently had the same skirts installed on his car too. Check out his white Zed in the rides section, it looks great.

 

 

Seez ya

 

Simon H

 

Oh yeah, the uni-chip cost's £450.00 supply and install. Takes just a day to do on the rolling road and what a great ride home you have after. Would say that an uprated clucth is in order though when you up the performance. The car chewed my stock one up and spit it out for arse paper in three weeks!!!!

 

[This message has been edited by simon h (edited 10-04-2002).]

I have to say Simon i really am Not a fan of body kits but i think your car looks f***in excellent!!!! What is the colour,is it a standard Nissan red or something else?

 

BTW i'd be very careful when it comes to clutches and do your research on all products as there's a big difference between the paddle clutch plates and the composite plates in what sort of punishment they can take and how they handle normal driving conditions ETC ETC waffle waffle!!!

 

Oh and Just incase you were planning on doing so i phoned AP about 6months ago to find out a price on a plate from them only to be told that they don't actually make one for the 300zx!!!

 

I finally settled on a HELIX kit in mine and it is a full composite plate made to my own spec,Just in case you were wondering it's not too hard on the left foot and engages very quickly,can be a bit tricky in traffic but it holds everything i've thrown at it so far so i'm happy.
