Installed the jb4 last night and did a few runs on map 1.
It drove fine, but I got a PO100 code now. My car is stock.
I'm driving in map 0 for now and I still get the code but goes away after a while. I'm guessing cuz of the auto delete option. But it goes back on when I start my car.

No autodelete in map 0... I would double check the wiring. It sounds like a sensor is not making connection probably.

Connections are good. But now Im getting a half engine check light.

That isn't a valid code. Read the code with the JB4 interface to see what it is.

if you're getting the half engine light then it is 99% some connection somewhere. Happened to me, happens to a lot of people. Email Terry or Jon at BMS and you can send them pics of the instal and they'll walk you through a troubleshoot.

Ok, checked the engine code it looks like code 270? Or 271
Speedo pointed at 0,2,7 and then 100

The code was on map 1

There's a guide that shows what numbers or letter correspond to the tach/speedo indications when reading codes from the Jb4. You must decipher the code

Order the cable, wont get that til tomorrow.
Now I have 2 codes now. I only read 3 digits though :/
You tube video of code.

Problem with the MAF sensor - check your connections again
