How good is Amuse ECU mod?

[winsome]

Hi Bros

I have a JDM model and now ready for an ecu mod mainly for the purpose of removing the 180 limit. I have choices of Mines, Amuse and the HKS VAC. Initially I had my mind set on the HKS because it leaves the stock ecu alone and I really dont need any more power. However friend of mine came back from a track day complained that on certain occasion the vac was not able to bypass the limiter and he wasnt able to pass 180. There were totally five GTR and four of them have Mines ecu tuned and they were all happy with no problem. But I have yet heard anyone have their car tuned by Amuse. I understand they tuned in such a way that suppose to be more aggressive compare to Mines. Anyone have come across any information of how stable is the Amuse unit? Any info is appreciated.....

Thanks in advance

Winsome

Hi Winsome,

Although we can supply most the JDM tuner reflash, i would recommend going for the best, user friendly and cheapest option being the accessport

Production accessPORT launch date announced + more

all the reasons why are listed in the thread.

The Amuse and other reflash are all done with the same software from Techtom. The only difference from tuner to tuner will be certain parameters which are a character of that tuner. From what ive heard the techtom is quite limited in what can be changed on the stock ecu i.e boost, rev, timing

The down side is that you will need to remove your stock ecu, a bit of a job getting to the ecu which is located behind the passenger glove box. You then need to place in a suitable ecu packaging and post to Japan, let them plug in the laptop for ten mins and post back to you in HK. If for any reason that ecu should get lost or damaged your in big trouble. The other option is get a Japanese tuner to fly out to you which will be even more $$$

Ive heard the newer GT-R (june onwards) can not be delimited by the vac or amuse/similar reflashes. it throws up a P700 code. Also a few reports in Singapore of GTR going into xmas tree mode with the vac.

A few of us have beta tested the accessport and have been happy. I hear Alf in Singapore is a ledgend turning off hood lamps.

Other than that looking forward to seeing what Dave Power @ ecutek will come out with.

Hope the above is of some help

Sorry for the "off topic", but what's all this talk about hood lamps?!

thanks for the info benji,

I know about the accessport and the flexibility is very attractive. the only concern i have is that it is a DIY reflash what if i mess up the upload in between, or so "unknown" factor happen in the middle then i am totally screw up? at least if the ecu is damage or lost or whatever the shop will be responsible? or am i worry too much about it?

anyone tried out the accessport yet?

Thx

Hi Winsome....

Noticed that your location is listed as Hong Kong. There are no Cobb dealers in Hong Kong as of this moment but perhaps very soon you will have local support. I run MB Motors in Singapore and are dealers for Cobb. Do you know Kayaba Shop in Hong Kong? Mr Koyama-san from Jun Auto is always there and I am sure he will be able to support you should you need help with the Cobb unit. We have reflashed a few cars with Amuse and Mines and will be putting the Cobb reflash onto the same dyno within the next week. If you have any other questions, just email me at keith@mbmotors.com.sg

Regards

I am probably too paranoid about it. the more i think of cobb the more i think it makes sense. not only can you reflash the rom but you can turn off unwanted error light also......

i think i am going to be on the waiting list also......

my chassis number is 3*** and i took delivery in May, can it be reprogrammed?

[tokyogtr]

mine's make very regular trips to hong kong. i've got mine's and never had a problem. never heard of anyone else having one either. i believe mine's even attend trackdays in zhuhai to help customers tune their cars.

Its going to be quite hard to mess up a reflash as you put it. There are safely features in place, so if your battery should die (within the 5 min up load) or the cable become disconnected or anything like that you can simply start again. I speak from experience... our early beta software didn't upload 100% and we had one dead gtr, until we started the upload again, no problems


I have also just posted some exciting news on our thread, that cobb has also included the option of reseting transmission error codes. This can be extremely helpful for people who don't have access to a Consult III.


Put it this way. you go for the amuse/mines option. Then at later date decide you want more power / want to add a different intake etc..

If you had chosen the accessport the maps are FOC to download and you can do it your self easily. Add to the fact that accessTUNER software will shortly be available. With the techtom you'll have to pay again...


Mines vs Cobb ? Cobb for the win

[First]

I posted this on Nagtroc. Will repost here to get more comments.

In a weeks time, my parts for Mines VX exhaust, Mines straight pipe (full decat), Mines air filter mesh and Mines VXrom running 0.9 bar wil have arrived. I was told I will make close to anywhere from 550hp to 580hp flywheel with ease in this configuration.

With the recent release of Accessport, this really screws up or at least confused my plans. I really really like the accessport and no doubt I'm going to get one just to reset hoodlights, tpms or checklights in case it happens. I have always written off Accessport's map until now. My reason is Mines VX rom map are proprietary ecu map for Mines exhaust, straight pipe and air filter. Who else to best extract all the performance out of their products other then their own ecu mapping right?

This all hold true in my mind until accessports development went well underway and I start to find people like Benji of GTC from Welcome - GTR OWNERS CLUB reporting 600hp flywheel running 100 octane with Sunline racing exhaust. I believe he did decat his catalytic converters as well. Add to that, the flexibility of accessports to change map whenever you want. I have not remap my ecu to Mines VXrom mapping yet as the Mines engineer will be coming over to do that for me so I won't have a GTR without a brain for 2 weeks.

Now there has been rumours saying that Mines might have lock its programming. I am afraid if Mines indeed did lock the ecu, after flashing to Mines, I'll never be able to use Accessport's remapping features anymore.

What do you guys think? Should I just go for Mines Ecu? Or should I just turn down the remap from Mines and go with Accessport's Stage 2 Map?

I really hope someone with indepth knowledge or experience about this to give some advise.

The question is "Would accessport's Stage 2 Map be JUST AS GOOD as Mines Ecu Map on Mine's exhaust system?"

Every car is different. Lets agree on that first. Every single car produced is different.

It might be minor, it might be major. Some cars are faster than others. Some are slower than others. Some cars make more power, some cars make less power.

This is life.

ECU's. All current ECU's have some amount of learning. They have some amount of feedback, especially this new Nissan GT-R ECU. They run knock sensors, multiple 02 sensor feedbacks. Boost control, misfire , etc ,etc.

Is it necessary to run the Mines ECU with the Mines parts ? Is it necessary to run the Cobb parts with the Cobb Accessport ? No it is not. The Cobb Accessport will be constantly updated. It gives you the ability to keep the stock ECU,and load a new map to the ECU in the car. No taking it out and sending it in.

Don't let any marketing speak try and convince you otherwise.

[doggiehowser]

I tested a friend's MINES and my Amuse reflash. I suspect the power figures are going to be very similar, but Amuse also worked on the throttle response which make the GTR much more usable, cos the car is more eager to rev.

FWIW, it is painful to see the car being dismantled to take the ECU out (and sending it to Japan) and putting it back together will never be quite the same again. For that reason, I'd go for Cobbs if I had to do it all over again.

Thanks guys. Sorry for the Hijack but pls keep the comments coming.

My situation is slightly different. Mines dont come to my part of country so I had to get them over by hiring them. Pays the air tickets, accomodations, service free etc etc. I'll go to any length.

Regardless, it will be the Mines guys reprogramming my car. They will tailor it to my driving style and the fuel available in my area.

But still having said all that, I think I'm coming close to making a decision already, I'll use the accessports Stage 2 map on my Mines product.

Lets hope this decision is correct. And now... to think of a way how to turn down their engineers... god. This is going to be awkward.

[First]

Benji of GTC, could you care to elaborate a bit more and make me feel I'm making the correct decision here? lol.

You ARE running 600hp now with BP ultimate 102 and Sunline Racing's with full decat right? This is with Acessport's current stage 2 map?

Care to speculate what kind of power I'll be getting running on Mines with full decat and Ron 98 cobb stage 2? Is 550hp possible?

[tokyogtr]

fyi, mine's are reading this board already so they probably know already...

I was talking to a couple of Mines guys today.
2009 Nissan GT-R: M-Works Garage Sale and Mines R35 GT-R Gets a Couple Changes



They were working on the demo car thats here in the US. Mines does some cool stuff, I just am not sure what they actually give to the consumer, compared to what one of their demo cars actually has.

For a new GT-R, its all about boost, with good fuel. If you have crappy fuel where you live, hot temperatures, you are going to be limited by fuel.

I have heard a stock GT-R here in the US, in 112 F temperatures knock on a 1-2 shift. Brand new 28 miles on the odo. 91 octane fuel.
