Thank you! I searched, but didn't yield any good hits. This is exactly what I was looking for.

For the software install, it's best to have a charger that will at least put out a couple of amps. I have two chargers: one for trickle/maintain (BMW branded) and one from harbor freight that puts out a max 6 amps that I use for software updates.

If you just have a trickle charger you can always do the DME read then charge back up and do the write to the DME. I know with my tunes from ESS, the read takes much longer that the write.
Some people just fully charge and do both at the same time but I like to play it safe

Thank you for the tip. I'd prefer to play it safe. I'll snag a good charger, always a good tool to have in the garage anyway. I get nervous messing with the software of the car.

Let me know what you end up with. I'm contemplating taking off my Shark Injector if I ever get around to sending an M3 cluster and my DME to Terra to have it coded, and then reinstalling it afterwards.

He can code it with the shark still on the DME if you want to keep the tune. What he needs to code is out of the range of the tune.

Ah okay. When I asked him a couple of months ago he suggested I remove the shark tune before sending it to him.

He was able to do mine with my Dinan tune still the DME but ultimately he's the one that will know. IDK how much of the DME the shark tunes overwrites but there is a good chance that if you reinstall the tune after he modifies it, it will overwrite what he did

Gotcha. I'll just ask him again whenever I get around to taking the plunge. I'm (blindly) holding out hope for someone to figure out coding on shift lights for the M3 cluster but coded for the M54...

[Sockethead]

I know he was close to figuring out how to code through the OBDII

Ok, I'm puzzled. I have a low tire and after searching the garage to find the tire air attachment (that was right where I left it so I wouldn't forget!) I can't get air into the tire. Tire has about 28lbs in it. I tried a bike tire and it fills fine. The compressor is on and fill line is wide open. I've disconnected and reconnected both ends. Any ideas??
