Are you using crome pro or crome gold. Crome fee will not allow you to datalog/live tuning

What version? If your using 1.6.3 there are alot of people that report issues with dataloging. Try switching to 1.5.3

6.1.3 i think now. my bodge wiring fixed the issue. logging seems to work fine with the stock ecu, really need to get a wideband hooked up so i can start some proper tweaking. cheers for the help. do you know where i can down load earlier versions of crome as when i try from the normal links i get told its and earlier version and it stops the install.

Thanks again for taking a look and trying to help

You can download older version of crome from the website. Just keep reading and you'll find it.
