I wasn't able to determine if it was still necessary to remove the dash to install this type of system. Can anyone enlighten me on this?

Thanks

if you do fuel only you can make a little adapter to make the haltech (or whatever ecu) plug right into the gsl-se harness, and then you don't have to change anything under the hood if you don't want to

i'm not sure about removing the dash, if the car was a gsl-se to start with then no, but if its a 12a to gsl-se ecu i think yes.

the timing on the spark plugs is different from s4 to s5 so if one rotor housing is from a different year, you are not going to have a good time trying to get the timing where you want it. will always be a couple degree off between the two.
