EcuWorx remap for Z4M

I'll survive, just got some niggling back pains after coming down hard on one side of my back.

Thanks Tom. I'll keep you in mind.

Final drive changes don't require any coding in manual cars bud.

Ouch, sounds painful:(
Ah yes, I hadn't really thought about why the fd change was in your other tools, I just assumed it was only a speedo correction thing but of course it must confuse the dsg software.
I think I can code the speedo with NCS, will take a look at it, it's way out now with the 4.44.
Drop me a line if needed, happy to travel. Cheers.

NCS expert can be used for speedo accuracy, but the final drive has nothing to do with it. it is based on wheel diameter and revs per distance.

I have coded mine such that is between .5 to 1km per hour off.

? Revs per distance is very much changed with a fd swap. I've just swapped from a 3.6 to a 4.44 and the speedo at 70 reads about ~10mph difference at least. Glad to hear I can code it in NCS, I thought as much.
ETA I guess you are talking about revs of the wheel rather than the engine. I'm not sure how but im almost certain the speedo is reading higher than it was with the old fd. I'll do some checks, maybe it's in my head

Rev per distance of the wheels, not the engine or driveline. Based on overall wheel diameter it will turn x number of times over a period of time displacing you x distance. The car knows speed based on this input from the wheel speed sensor, not engine rpm.

Some great progress there OP. Hope your back is better soon.

Cheers.

Yep you're quite right of course, I think the only checks I need to do are on my brain

I'm sure Martyn can do a remap for that?

The supercharger one? I think at my age a little boost would dial it in a bit

Any updates on the ECUWorks Z4M tool?

It's ready to go, I just haven't released it as I'm thinking of migrating all of my software to be web based.

Great news, it'll be much appreciated

How long does that usually take?

For those of us ready to use the software, can we purchase the desktop version?
