Alright

[Spectral]

I ordered the one in the link (Green board) , and it seems to have the same issue as the screenshot above. This is my second cable (white board previously) and second OTG cable (bought the one in the link just in case)... maybe its the phone.. (Galaxy S3). Might try another Android device.

[martymil]

I have three and all work perfectly

Did you get the cable from the supplier I linked to ?

As you said might be the phone

[Spectral]

yeah, straight from those links as I had tried another earlier and got a white PCB one.
I tried another android phone earlier (Motorola TC55) and same thing... but I have another option again to try tonight I guess.

[martymil]

The problem with phones is that the manufactures customize the firmware and that's where the problem might lay.

If you where in Sydney I'll let you try my tablet as that's guaranteed to work.

[Spectral]

Got my android nutter mate over and he loaded some firmware of a different kind that he said supported usb host mode properly. Then it connected and read the ECU ok for a little bit. I didn't have a charger connected at the time so the car shut off the odb port like it does the radio after 5 mins.. My battery is probably slowly on the way out being 5.5 years old. I'll get a charger hooked up tonight and try a full read then write with any luck

Thanks for your help

[martymil]

You always have to have a charger connected whilst
reading or writing, it's an absolute must no exceptions

Glad I could help

[martymil]

Btw reading the ecu should take less 5 sec

[martymil]

Btw Taking the radmo link down the holder doesn't suit our cars

I came to this thread to ask that question. Thanks!

The Brodit/ClicOn stuff is a tad overpriced...

You don't need one for a 2 minute write.

If the ECU has an unknown bin/version on it it will take 76 mins.

[martymil]

Depends how good your good/bad your battery is, not worth the risk.

Especially when your car has been sitting around for a few days.

In the workshop any ecu flash, a charger/power supply is always connected.

[T1M]

Well it's not an 'absolute must', just wanted that to be clear. It's dependent on the situation. Good battery/not depleted from sitting round a 2 min write is fine.

[martymil]

If you want to play Russian roulette with your dme
go for it, but please stop don't giving bad info to other members that rather play it safe.

If you want to have a guaranteed write do it my way

If you possibly want a corrupted dme through a failed write due to the car shutting down because someone is being lazy to hook up a charger be my guest

I will not promote your way to anyone and you should not either.

Choose what ever way you like, but I'll stick to doing it my way

From MHD FAQ

Q: Is a battery charger required?
A: It is highly recommended for long flashes (install, uninstall). A healthy battery will handle short flashes (map changes) fine.


So is MHD giving "bad info" for their own product?

[martymil]

How do you know someone has a healthy battery?

Half the people don't even know how to do the most basic maintenance
But yet they'll play with things like flashing dme

You assume people know what they are doing

I find that most people on here do basic maintenance on their own car. I'm talking about oil, oil filter, plugs, coils etc.

No need for a charger for a 2 minute write. Yes it's a good idea to have one but I've been flashing N54's for 5 years (majority has been via COBB AP) and only use my charger on long reads or long writes. Even then I sometimes don't use the charger. My car is still on its original battery which is over 7 years old and has had well over 100 flashes done.

No, I didn't assume anything, and judging battery condition is a whole other issue and outside the scope of our discussion.

We were discussing electrical flashing facts. You made the assertion that a battery cannot handle a 2 min write and said the connection of a charger is an absolute must, no exceptions. This is incorrect, as stated by many others and MHD themselves. I politely corrected you and you accused me of giving out bad info to members.

You are free to do whatever makes you feel comfortable but please stick to the facts when handing out info, else make it clear you are stating your opinion.

They must contradict them selves then because the software says something else

Really where does is say the battery charger is not needed.

Even their own software has a little message before you flash in big bold lettering, so I'am sticking to the facts.
If its recommended, its needed. If you don't and something goes wrong, your on your own basically.

They are not even confident that the battery can handle a 2 min write, that's why they recommend a charger.

Like I said you want to take a risk go for it.

They have to make an all purpose disclaimer in their app. But they have said on the forums unless the battery is drained (poor condition/car has sat a long time without running) then a 2 min write is fine without a charger. Many other experienced users back this up.

As per another one of MHD's posts, if you don't have a charger on hand and have to do a long write, then you can always pull your fuel pump fuse and it won't run, which helps the battery out as it only has to power the DME:

They can't make any guarantees and have to pander to the lowest common denominator, but this really is just a matter of using common sense.

In their FAQ thread, and in their general info threads on E90 post, N54tech etc like I said above already (and quoted from).

You've made this thread to say you bought a new cable and have decided to use the MHD flasher. The first post was useful. 29 days later it's now moved on to you handing out opinions as fact, potentially misleading those new to or considering flashing, and you calling out and arguing with those with more flashing experience than you.

If you (or anyone else) wants factual flashing/MHD app info, just use any of the official MHD threads found on this and other forums. This has all been covered already.

If you want to document your flashing experiences and opinions, it might be better suited to a 'build thread', as it's specific to your ride and your preferences/opinions? People can still read it and follow your progress but won't mistake it for official flashing info.

If the software developer puts a disclaimer in and says we recommend using a charger,
use a charger.

Threads and opinions are just that, who knows who wrote those threads from mhd.

No way of knowing and easy to get out of if something went wrong.

Stick to the facts of the software developer and what is written in the software.

Like I said if someone chooses not to use one and something goes wrong, your pretty
much on your own from there.

Now if something goes wrong and your using a charger whilst using the software step by step it was designed to and something goes wrong, they can be held responsible, as
long as you can prove it.

So whilst its recommended, its necessary and a must if something was to go wrong
to cover yourself.

So again not my opinion.

So unless you email the software developer and they say its definitely not necessary to
use a charger in writing you must use one. (good luck)

Until then facts trump opinions.
