Anyone know a shop that’s good with electrics?
 

So recently my z messed up, and I took it some shop around my house and they diagnosed it with a bad ecu and fuse box. Dude wanted to charge me 600 for a junkyard ecu, and then upped the price to 1.8k when he said he found one at the dealer. He quoted me like a 2.5k repair but what made me doubt him is he kept upping the price every time I talked to him. So does anyone know a good shop that works on these cars specifically around the la county area. A bit further would isn’t preferable but I could make it work if anything.

Also does anyone know if ecuteam.com is legit?
