How many people on here have either one of these chips? whats the difference between the two, which gives better performance?

 

Also have many people got Mines chips and what performance gains can be had from these chips

 

thanks

aki

first of which chip do you have?

I would try and post a sensible answer to this but since it will just turn into a childish batch of name throwing i wont bother.

 

Just do a forum search - I posted the relevant views on them a while back before i lost my will to post anything other than playground crap !

 

Enojy the carnage that follows and i hope you get a good ecu Aki .

 

p.s JWT

I woudl go with NICO on this JWT is your best bet.

Mines are a very reputable company in Japan and do make some awesome stuff for cars, by far and away if you look on the skyline forum and just look how many of the r34s have mines ecus youll see what i mean.

I have a mines ecu and im very happy with it, but they are very expensive and difficult to get hold of. So jwt would be the way to go.

I've got an SE chip, and I'm pleased with it, no detting what so ever and a good power increase, they map it specific to your car.

I think the JWT gives a little less power because they are mapped within safer limits.

If you are taking your car to SE don't expect it to be done quickly! try and pin them down on how long it will take.

I have a JWT ECU fitted that was supplied and mapped to match the JWT Sport 500 Turbos and JWT 555 injectors that were supplied by Stillen at the same time. The engine was taken out by my local nelson when one standard turbo blew and we agreed at the time that upgraded turbos would be better than standard Nissan ones. So he looked around for me and spoke to the supplier on my behalf arranging shipment etc. (Since found out that MJP Eastern Autos can get the stuff without me having to deal with the shipping duties, etc)

 

The car prefers running on Optimax as I guess it matches the US fuel octane, but I am no expert on that. As I dont have a boost controller I am just using the standard wastegate and boost (14.5psi) and the car pulls great and that is good enough for me at least.

 

I have seen a lot of comments on here that SE ECU's are better though as they are mapped specifically for the UK fuel, etc but I like mine as it is. If I was spending the money again, would I go for JWT over SE? SE seem to do a good job but people seem to imply that they are not very fast getting the work done, maybe someone who has had an SE experience can comment.

 

Customer service from both Stillen and JWT is excellent however and the kits came through with really good instructions and both Stillen and JWT answered phone calls and emails promptly. The only problem for me was that as I was handling it direct with Stillen they charged me a "core" cost whilst awaiting for me to return the old ECU back to them on exchange, but they creditted my card within days once it was sent back to them. Hope this helps. If you in the midlands you can always come over and take a run in the car.

Aki ask someone who has had both,Andyp or ChrisC,and they will tell you JWT=KAK when compared to the SE chip.

BUT that is only because the SE is custom mapped to your car, whereas the JWT is a safe mass market upgrade.

 

If JWT were a UK tuner, and they did custom maps for each car, then i have no doubt there would be minimal difference between them.

 

The difference would be which was prepared to go the leanest to extract that little bit more power.

 

If SE produced a mass market chip which you could buy by post, then i am damn sure that it would be lot more conservative (like the JWT) than each one of your custom mapped chips.

 

To say that JWT=KAK when compared to SE is a misleading statement.

 

SE up the boost, then map your chip to match the max boost that they give you, so that it works safely.

 

JWT give you a mapped chip, which will safely work within the confines of the parameters defined for the chip you buy.

 

SE can see the upgrades and condition of your engine to tune the chip with.

 

JWT advise what chip is suitable for what level of upgrades you have done to your engine.

 

Just as a point of interest, i think JWT are the only tuner that are officially licensed by Nissan to modify their code, afaik.

 

 

Ahh Craig my friend - I see you are still willing to waste your time in the face of such ill backed up fact where im not !

So at the end of all that the SE chip gives you more power LIKE I SAID .

 

 

 

------------------

Don't know why I'm bothering answering this cos I know the SE screamers are not gonna reason this out. Basically any "Off the shelf" chip is gonna give comparable results if it is intended for use in the same country with the same level of mods. I don't care how many people say the SE chip is better - it is tuned to the specific car with the cars specific mods!!!! Under the correct conditions an engine will proce a certain amount of power for a certain amount of fuel and air - more fuel and air=more power obviously. Depending on how close you want to go to the limit affects the last few BHP you can squeeze out of the engine. However an engine that is running on the critical limit on a cold day will do its best to take itself apart on a warm day with inferior fuel. So really no chip is better - they are both good at what they were designed for - and btw, I bet JWT could get more out on a custom mapped chip than SE can

 

Why didn't I just quote craigs post and put my name to it???

------------------

These dyno charts were posted recently by Andyp and seemed relevant to this thread.

 

 

 

------------------

It all boils down to the record of the company

 

A: MINES are a huge name in Japan, One of if not the biggest name in ECU tuning in Japan.

B: JWT - Huge company, very well respected in the STATES. (NO problems)And used to race race winning NISSAN GTP 300ZX TT. In the american gt series, won everything there is to win.

C: SE - no comment.(well i could comment but i wont)

lets face it if the japs and american set up shop over here se wouldnt stand a chance but as they're not about to se are going to make hay while the sun shines......wots needed here are more companies like options setting up over here not only would costs come down but we'd get better service......but we're in good old blighty where good things dont come our way and we all politely take a rodgering because thats the way its always been

Steve - I notice NO boost figures are marked on those graphs!!!! Unless conditions are IDENTICAL then the comparison isn't worth making

 

Thing with rolling roads is - they are good for tuning a car up to get the best out of it - they are not much cop for comparing cars really.....

 

CheerZ,

 

Andy

 

------------------

Just to clarify one point. SE will modify a chip to suit your car but they have at least one, maybe more, that are available off the shelf and have been setup for certain configurations. If you have particular requirements then they will set it up on a dyno. (expensive due to dyno time but worthwhile if yoiu are chasing silly numbers)

 

Obviously the SE base product works best with an appropriate exhaust, intake and boost upgrade - exactly the same as JWT for their base product.

 

The graphs above were run with SE/JWT back-to-back on my car at the dyno day last November. Having said that I still have a JWT chip in my car because the one I borrowed was Tim's and I don't have one of my own at the moment ( and because I forgot to ask last time I was there).

 

A number of people have SE chips and as far as I know they are all happy with them. The reason they work well is that they were optimised for UK conditions/fuel etc. Whilst I'm sure that the JWT chip works with UK fuel, I doubt whether it has been set-up specifically for it (as we are hardly a significant market for them) and consequently they are at a disadvantage. Also the parameters within which they work will be broader ie they have to be safe everywhere from the deserts of Arizona to freezing conditions of Alaska or whatever.

NO NO NO its like this

MINES= in a 300ZX will dett like a twat.

JWT=mild upgrade.

SE= CHIP kicks ass BIG STYLEE.

You need to ask Andy and Chris,they have both.we don't live in the USA do we we live in the UK.enough said.

 

 

 

 

------------------

Lets have a game of ECU tennis - on one side of the net is JWT and on the other side is SE.....

 

The above shows why people can't be arsed replying - nobody gives good arguements - they just say theirs is better full stop.

Ian what ecu do you have ? nuff said

I agree with Duffman, there is no conclusive

proof which is better. I have an SE chip which I'm more then happy with.

The only conclusion we can draw from this thread is all 3 (SE,JWT,Mines) give good power upgrade. One bit of advice I can give is DON'T FIT A SUPERCHIP, I discovered there was one fitted when I bought my car, the car didn't feel as fast as the SE chip fitted afterwards, and the Superchip detted all over the shop!

Warren it only happened the once it was shit fuel.It's had that chip for 18 months.

 

------------------

Macca you walked straight into that one m8

 

Your car is mapped too close to the critical limit for the crap fuel they supply us with over here...

 

If you didn't know what detonation sounded like I think your engine would be in Zed heaven now m8 - you were lucky!!!

OK then Duffer WHY has Warren being getting Detonation all this time and he has no SE chip???When will his go to heaven???

I feel a real big NICO post coming on .

For all the trouble it's worth why not just get a totally custom engine management system like the AUTRONICS one i have in my car and then every time you mod the car in any way just set the system to record 1 hours worth of road driving in all manners and then re-programme the ecu from the laptop piece of piss.....Hell of a lot easier and a HELL of a lot better than all the shit these tuning companies sell and i bet its not that much more expensive than the cost of a chip and a rolling raod session to get the thing running right!!!

 

Just my 2pence worth of useless info...i'll climb back into my hole now......
