Its in the engine bay on the drivers side near the firewall.

Its under the black cover that gets unlocked and slides off.after take the cover off you will need to unclip about 4 sets of wires to completely get it free.

Hope you decided to go with my tune also bro!!!

Thanks Scratch! Yes I've decided to go for a full Kleemann ECU tune but it will be slightly different that yours as I don't have the Throttle Body and pulley that you have.

Cory is a rockstar so thanks again for all your help!

Damn can't get it out LOL. Been working on it for over an hour in the garage trying to be super careful not to pull any of the wires out. Any tricks to it or special tools you'd recommend?

I'm a mechanical idiot so it's probably just me.

No go, worked on it for over an hour with a bunch of tools so I'm going to have it removed at the shop then FedEx it in from there. It's a bit of a minor convenience but I didn't want to take a chance pulling out one of the wires by mistake.

I suck mechanically so I've learned to be OK with paying for professional help. I don't think it's been removed in 8 years so that's probablly why.

There's a Kleemann authorized dealer near me so I'll have them remove it and Fed Ex it to Cory. So all is well!

Thanks again for all your help wit this Scratch.

EC tunes are fantastic but I'm having a bit of trouble passing emissions due to my OBDII showing, 'Not ready" so Kleemann can help me in this regard.

Nothing against EC, I highly recommend their tunes for the raw power. (See video in sig).

Yeah followed that to the letter but the pins will just not budge. Again it's been in there for 8 years and never been removed so that's probablly why.

Will have it removed professoinally for me tomorrow/Tuesday and will be good to go!

Thanks again.

Alex
