35iS exhaust side

Any idea how this affects warranty?

+1 although mine is now the extended BMW warranty with AWP Assistance/Allianz.

Had a look at the MHD site but confused as to whether it uses your own stock map to revert back too, or one of their own? The reason I ask is it lists the 35is but shows the stock map as 306hp when it's 340?

It can do both.

You can perform a backup, which can be restored at any time. Or flash the MHD 'Stock' map.

Would almost certainly void it if they found out. You could always restore the backup if you need to make a warranty claim though.

That cable seems cheap. Plus it states for cars up to 2008? There are others up to £40 or more, there’s conflicting thoughts online about the cheap cables bricking ECUs...

In my experience they're identical. I have a £50 cable and a £10 cable. Internals are the same.

The website has links to approved cables. go for one of these if you're unsure. http://mhdtuning.com/support/

Fab thanks.

Mainly want it for logging to get to the bottom of my engine injector issues. Then it’s playtime because frankly why not.

No problem. have you tried ISTA or INPA? Probably better for logging/diagnostics.

Cables and INPA arrived. Will take a look tomorrow but want to be careful as INPA and inexperience seem to make for a bad combo.
They will work with the same cable https://www.ebay.co.uk/itm/For-BMW-INPA ... SwrIlaw9iZ

If you have trouble installing inpa, try googling bimmergeeks. They sell the cables and have inpa, ista etc. for download.

I've installed it a couple of times on a Windows 10 laptop and never had any trouble.

Some guides tell you to install an XP virtual machine, but it's not necessary.
