MHD update

[Superdaws]

Anyone running the new MHD maps with sport cooling yet?

[T1M]

A few. Brad87's been using the feature since well before it was released by MHD. While you can overdo it with the ambient temp thresholds for each mode and it will cause the pump to run more often and faster, it appears to work as advertised.

is there a place in sydney that I can get to assist me with MHD upgrade to my car? I dont have the space/equipment/location to do it myself.

Don't be daunted. It is literally the easiest thing you'll ever do. You don't need any space or equipment. Literally all you need is a tablet and K+Dcan cable and a battery charger is recommended.

I bought the cable from eBay for about $30 and I bought a cheap tablet from Officeworks for around $50 but if you already have an Android device, just use that. You can get battery chargers from Supercheap or Autobahn for not much at all.

Take your time and you really can't get it wrong. It's as simple as plugging a cable into the OBD port and pushing a few buttons.

You *need* a battery charger for the initial flash.

so if i go to a workshop and they charge me x amount (in the hundreds, just cant remember) am i getting ripped off as this is something i can do myself?

Most definitely getting ripped. Do it yourself or find a member local to you to help.

Yes, I should edit my post to say this.

I have heard of people doing the initial flash without a charger but it's risky as shit. Definitely use a charger the first time you flash a map because it will take around 40 minutes.

Absolutely. Literally all they're going to do is plug a cable into the OBD port, push a couple of buttons on the tablet and then leave it to write the map for 40 odd minutes. The actual labour time will be about 2 minutes. I wouldn't want to pay someone hundreds of dollars for that.

Just buy the equipment and do it yourself. The cable and charger aren't expensive at all and even if you don't already have an Android device to use, they're cheap as chips. It really is very simple and the MHD interface is very intuitive.

I honestly don't see how anyone could get it wrong. Just connect the battery charger, plug the tablet into the OBD port with the K+Dcan cable, open MHD app, select "flash a MHD map", choose the tune you want, then hit "write map". From there you just leave the tablet to do its thing and don't touch anything until it's finished. That is literally all there is to it.

Alright, I know it's an old thread, but I have now bought the Cable, have the Android Tablet and about to get the MHD license.

Major Question: Will a trickle charger suffice or do I bloody need to go buy another charger just for the flash?? I own a trickle charger, don't want to buy yet another charger.

If you have a solid battery you'll be fine. If youre not sure just setup a car with some jumper leads and let it idle. the new flash disables the fuel pump so you dont need to pull the fuse...

So, hook up the trickle charger and turn the car on?

No, just hook up another car like you're jump starting it.

how many amps is the trickle? if it's >5A should be fine. just turn all lights off (including angel eyes).

huge chargers were only really needed before mhd fixed the issue with the lpfp running continuously throughout the flash.

UPDATE:

Bringing up an old topic to provide an update on information. I contacted MHD about my question, and they have confirmed that a 5Amp trickle charger will be fine, as long as all options such as auto headlights etc are switched off, and usb sticks, phone chargers etc are removed.
