MHD/BMW Ediabas/INPA K+DCAN Cable

[martymil]

Good to know, don't want to post links to dud cables

But there will be always one in every batch

[Dat Aus]

Alright, so I've got my cables from the sellers Marty linked to in the original post. My new charge pipe should be arriving either late this week or early next week. I think I'm ready to flash my car.

I'm an iPhone guy and don't have any Android devices. I could borrow a family member's Samsung phone but I'm thinking I should just spend the extra little bit and buy a dedicated device for whenever I need it.

Can someone tell me if either of these will be suitable for doing the MHD flash? I literally have no idea when it comes to Android. I don't intend to use it for anything other than the MHD software.

The one I linked to at office works works perfectly 100% every time

Leave it in your glovebox and don't use it for anything else

The problem is is the mhd app locks to one google account and can get tempramental
if used on multiple devices

Do yourself a favour guys it's peanuts what it costs but can be costly if something goes
wrong, keep the BMW apps on this device seperate and use it for flashing and gauges

It's just cheap insurance for very little money

[Dat Aus]

Thanks. I must have missed that in your post.

Is there a way I can test my cable before I start flashing?

[martymil]

As soon as you connect it, it should come up on the screen

First I've heard of this temperamental behaviour. I take it you read this posted by one other person somewhere so now you're spreading it as gospel like most things you post?

FYI I have my Google account on 4 different android devices (2 phones: galaxy s5 and s7 edge, and 2 tablets: nexus 7 and some cheap 7" thing from target) and all work fine for flashing without conflicts.

What should come up on the screen? The app?

Also, I have an old trickle charger. Will that be sufficient to keep the voltage up?

If you purchase with one device and then do a purchase on another Google has locked further purchases until you ring them

Has happened to me when used with my Samsung phone and the android tablet and it's not something I've read somewhere

Really gospel, i'm posting something that works 100% every time so people don't brick their cars

If someone wants to do it another way, go for it.

If you want something that works 100% tried and tested read first post.

Depends on how good your battery is

If it's on the way out no chance

You need something with a bit more juice

If your battery is good condition then use something like in the first post

If your battery is old I suggest a 20amp charger and turn everything off

[Dat Aus]

Thanks, Marty. Sorry for all the questions. This is my first time doing something like this so your help is very much appreciated.

[martymil]

It's all good

Ok. So I went and picked up the Lenovo tablet from Office Works today. I have my cables. I'm about to download the MHD flasher module and stage 1 tune. I have a battery charger ready to use.

Anything I need to know? Will the app walk me through what I need to do? I recall that I cannot touch the car while the flash is happening. Do I put the driver's window down before I start and then just leave the tablet on the seat while it flashes? I don't fancy sitting in the car for 40 minutes while it installs.

What happens if my battery charger is insufficient and the voltage drops below the required amount?

It will shut down and brick your car and you wont be able to start it

you will have to reflash to stock, again the charger has to be able to keep up
otherwise it wont work either

[Dat Aus]

But it will be fixable, right? Just need to re-flash to stock?

Would it be worth bring my brother's Hilux over and hooking up the duel battery system from it?

[martymil]

never tried it

cant borrow a good charger from someone ?

if it drops below a certain voltage it will shut down no matter how many batteries you have

the only way to ensure it doesn't drop voltage is to run your brothers car for the entire flash

[Dat Aus]

You suggested a 20 amp charger, right? I only have a 10 amp. Will that suffice?

Pull your LPFP fuse before flashing as this is the main drain while flashing.

If your battery is in reasonable condition with a charger there shouldn't be a problem.

[martymil]

10 amp will be fine, just make sure you turn everything off

heater, lights, radio or anything else that draws voltage

put your battery on charge for a few hrs before flashing too

[Dat Aus]

What position should my ignition be in? Just press the starter button once, or twice to get everything on (except engine)?

[martymil]

Everything but engine

Make sure reds are on but engine not started

[Dat Aus]

Thanks.

Is it ok to put the window down beforehand? Or does it have to be closed for some reason while flashing? I plan to put the window down and then leave the device on the seat while its flashing? That way I can access it to check progress without having to open the door.
