As above ive had this fitted to my 2wd sapp cosworth and not to sure if level 1 or level 6 as ive bought another computer and it is supposed to be l6 and has a different colour screw cheers.

 

L6 OR L8

 

Hi thats confusing as the one i have fitted now has a dark grey screw and is supposed to be l6 i thought the white one was l1.

 

has it got small wings on the side with holes in to screw it in

 

Just looks standard to me both look the same?.

 

For pictures of the ecu versions see: http://www.bigturbo.co.uk/main1.htm

 

The L1 with model number ending in 1 on case has a YELLOW screw, as fitted to 3 door cossie.
The L6 with model number ending in 6, has a white screw, that looks more like silver/grey after a few years, the L1 yellow screw is a very definite yellow.
Definitive way is read the model number on ecu case, assuming no ones changed the pcb!!

Thanks to you and tabetha both of them must be l6 its just the other one must be a dirty screw as my original one is white.
