Is there anyway to get the data from an ECM? I don't want to break anything. Just want to get some info.

 

You have to be way more specific than you "just want to get some info"

There are a few obd tools out there that can read just about anything you need...

 

I want to get the info for speed. The data maps or math stuff that calculates the speed from the vss. Same with rpms.

 

Why on gods green earth do you need that lol

That info I know nothing about, but I'm gonna GUESS that you won't be able to get that from the stock ecu. Lol forgive me for not having any useful info.

 

Do you want to save the info? or just want to see it when you're driving? for the latter you could always get a scanguageII

Good luck man.
If it hasn't been done, there may be a reason for it, but like I said..good luck.
I like to witness electronic miracles.

 

Challenge accepted.
