Laptop for tuning needs

[SirBrass]

I know plenty of folks abandoning apple in droves as OSX becomes more locked down and more like iOS than the old Mac OSX. Apple seems to like the idea that Windows RT has.

See ya, Apple. Let us know when you start being inventive again and stop suing everyone that has a white phone with a single physical button...

And how DO you bring back the traditional start menu button in 8? I've looked and can't find that option. Instead I have about 3 different ways of getting to the Metro UI when I only really need one (charm bar).

I use a spare mac book to run win7 on bootcamp for flashing and logging. Works fine. Never use windows outside of that.

And it takes forever to flash with windows on a Mac. Ask @nelsmar

he said it only is a problem when dynoing. so if you aren't dynoing save your money and use bootcamp

3 minutes vs a minute minute? negligible

I've looked at the T-100, Lenovo Miix 2 and Dell Venue 8 Pro.

I need to know from experience, which one of this will absolutely flash the car in 1 minute or less.

I have a mac, have run parallels, bootcamp and vmware and they are all within 3-4 minutes.

I would only get a new device if I can get flash times to 1 minute or less. Now that I am fine tuning the car, I hate to have to sit 12-15 minutes a night just to see the car flashed.

I believe @nelsmar uses the Lenovo miix 2 and it is close to 1 minute? If so, what USB adapter are you using?

Again, this device will be use solely and exclusively to run Ecutek, don't care about nothing else and want to know it flashes in about minute.

Thanks.

ECU tek should consider using usb3. This will significantly increase write speeds. I don't know much about the data transfer speeds of ecutek, writing a rom to our car. but in general, usb is going to be a bottleneck when writing data.

You can accept the fact that the "metro UI" is the new start menu and functions almost the same as the start menu of old or use one of the many options to bring the "traditional" start menu back and quit your bitching.

When vista came out, everyone clung to XP. When. 8 came out everyone clung to 7. Meanwhile Apple is breaking records for user adoption rates.

^take that as reference, why does microsoft ALWAYS have to fuck around with their OS? Why do we as paying customers have to always re-learn how to use their damn OS? XP to vista wasn't too bad but the jump from 7 to 8 is fucking terrible.

As a long user of microsoft products, I wish they just kept it the way it was back with windows 98 and not have to re-learn how to use a freaking OS.

Because that USB3 performance will significantly help boost the performance of the ISO 15765-2 connection that is running at 500kbs. Oh wait... no it wont. The issue with the flash time is due to latency of hardware not the actual transfer throughput. A lot of hardware is used as passhrough allowing the actual computer to send commands via canbus vs buffering the data to transfer on the hardware (the cable). The cable is capable of processing full speed and the software expects there to be a specific latency due to it being a pass through device and a virtual environment does not provide this, as well as some older chipsets.

I haven't read up on the USB3 spec's but im going to assume the newer standard doesn't improve latency just throughput. However I could be incorrect about this. Also flash time could in theory be slowed down due to heavy can bus traffic.

I disagree... But for the record i never did try flashing via my mac using bootcamp only parallels. I used to flash in ~2mins but was told directly from Xavier @ Ecutek to stop doing this due to the latency issue in which I am familiar with since I have been developing canbus based hardware as of late.

When it comes to time... the money is well worth spent for a cheap tablet JUST for flashing for my own purposes. I have been doing ~ 100 flashes a week and thats an assload of time staring at the gauge cluster lol.

Take your Macbook. Install a SSD in it. Install W7 on a bootcamp partition. Call it a day.

You can run W7 in a VM but flashing is way slower that way.

nope you got it right. That's why I'm saying I'm unfamiliar with this territory of computing. usb3 wont help in this case. In the simple solution of writing a rom to a device, usb will be the bottleneck.

definitely something I'm interested in learning. Coming from a world where I'm daily dealing with 10gigabit connections, kinda weird to think about such slow data transfer speeds

I just wish I wouldn't have sold that old netbook...

Install windows 8.1.

I'm not talking about people switching to Mac from another platform, I'm taking about when they release a new a major update to their OS. When Mavericks was released they broke a record for adoption:

Windows 8 on the other hand has been available for 15 months now and companies like Dell and Lenovo are STILL selling windows 7. Dell even recently released a new generation of their Optiplex SFF's and they come with Windows 7! Do you see anyone complaining that Apple isn't releasing new computers that run Snow Leopard?


As for the USB3 discussion: USB2.0 gas a potential throughput of 480mbps, and the full rom is 1.25mb including whitespace. If USB 2.0 were the limitation it would flash in under 1 second. Hell, it would have time to write and do a verify on the write at least 5 times in 1 second.

Also I have flashed using ecuflash in VMware fusion on my mac and it is exactly the same speed as on a bare metal laptop. The limiting factor is the ecu.

FWIW, my old laptop does not flash any fast at all.

I would like to find out what is the determining factor in the speed (I'm only interested in FLASHING, nothing else).

Is it the SSD drive, is it the USB 3.0 port, is it lots of RAM, is it a really fast processor?

I'm inclined to think its the processor.

It is not the ECU. I have a retina Mac (SSD, usb 3.0, i5 proccesor) and I flash between 3-4 minutes on VMware, Parallels or Bootcamp.

@nelsmar flashes with his 8.1 tablet in 1 minute and 35 seconds.
