Awesome content keep us updated i can't wait to see more . I hope that sludge in the oil didn't hurt the bottom end , because these bottom ends can make good power stock long block. What is your power goals?

Personally if I was you I'd just wire in my own . First get an general idea of wiring and reading wiring diagram. Then go wire by wire and wire the ecu to the factory harness. You shouldn't have to remove the dash to get to the ecu. But if the ecu is under the dash like most older Hyundai's it can get tight. But if you can pull the loom down a little it can help with more room.

Yes I wish I could do it on my own but i reckon it’s a bit out of my skill level. I can wire car stereo’s but an ECU hmmm maybe not.

I found another guy that specialises in ecu installs, custom engine harnesses and tuning with Haltech’s. His quote was $1500 install and $800 dyno which is a fair bit cheaper. Im going to go with that, I just have to drive a bit further to his shop.
I understand that not everyone is willing to jump into wiring like that and I know why. Also Thats not a bad price definitely I'd go with him mostly if he does great work.

I haven’t really done anything else with the Elantra, I did notice some oil weeping out of the dipstick tube where it connects to the block. This got me thinking it’s got some blow by. I did a compression test and got 214-218psi across all cylinders. I believe 220psi is ideal, so it’s close.
Maybe the o-rings on the dipstick tube need replacing or I could run a 10w-40 oil instead of 5w-30.
or it just has some blow by.
Is oil leakage from the dipstick the norm for these engines under boost ?
What Chris said check the oring on the dip stick also I would recommend you running 5w40 or 10w40 since it's turbo now just to have something q little more thicker. Also I can't remember but what's your catch can set up?
