I'm months away from a tune but thinking on it. I've never had a tune done, last build was a crude work around with an FMU (for sale btw).

Anyway I'll be using an SCT chip on an A9L. I assume the computer has to come out, be programmed and then slapped back in for another pull.

I've got the dash out of my 91 and am wondering if I should leave the heater fan uninstalled to allow access to the computer? Dash is about to go back in and it's decision time. Also time to post a sneaky f#cker double DIN rig I made.

I know the computer can be removed with the fan in place but I'd rather spend my $$ on tuning time over wrestling the ECU in and out.

looking for feedback from the experienced hands here.
