MHD first full write... is this battery charger okay?

Neiman Levenson · 04-05-2017, 12:34 PM

Hey all, So Im finally getting the ball rolling on tuning my car. It was a nightmare finding the right android device for MHD simply because I bought a used device at first (samsung galaxy s3) that had a damaged port. Since then Ive picked up a refurbished nexus 5 off ebay for $90 and couldn't be more happier with it! I already had the OBDII cord and OTG cable so I Instantly hooked it up and bought the monitor module which is very cool.

Now into the tune: Im going to flash a tune in the next couple days and was thinking of picking up this battery charger https://www.lowes.com/pd/Schumacher-...c-00ff86febf6c

will it suffice being 8 amps? anything wrong it? Thanks for the feedback in advance.

Heres a pic of the nexus 5 and where im planning to mount it once my car is tuned!

I have one of these that the car sits on in the winter, no issues when I did the MHD Flash.

Should be fine.
I just use the trickle charge setting on mine, connected under the hood.

I purchased a generic charger with the right amp from Walmart, but had to leave the car plugged in for about 5 hours after the tune to get it charged fully. Straight install otherwise.

thanks guys i'm going to use it and i'm considering pulling the lpfp fuse as well just to be on the safe side, have any of you guys done it and happen to know which fuse it was off the top of your head?

Fuse #70

Turn off all your day-running lights and pull fuse #70. You'll be right.

Everyone on here recommends the c-tek chargers, but I've done all my flashing with an old traditional 8-amp charger from supercheap auto.

I really think most of the problems with charge are from before people started pulling the LPFP fuse.

it shouldn't take more than 50 min.. that charger is fine just plug it in a little before and unplug 70 if you'd like. turn everything off

I used jump start cable to connect my other car with 135i for first time flashing. I live in an apartment so power supply is limited. The first time really takes about 40 mins to an hour for its job. Just to be patient and never let your friend or yourself touch the door lol.
