Cx racing turbo kit installed now has rough idle and goes rich after start up
Just installed turbo on 92 Miata, currently have stock ecu, stock injectors, wide band sensor. I do plan on purchasing megasquirt ecu, and 420cc injectors. I did first start up it idles fine for about 5 seconds then goes really rich and wants to die. Any recommendations?

Take off turbo kit. Install Megasquirt. Learn to tune. Install injectors, learn to compensate for new injectors. Install turbo kit. Have a great time tuning for boost because you already learned how to do it on a stock motor. Be happy that you didn't blow up a motor using a stock ECU at first.

How are you going to make sure you have the right amount of fuel in boost? Stock ECU does not support that.

like others have said, you need megasquirt and injectors. Stock ecu can't run a turbo. You will blow up the motor. Very....quickly.

Well, not to knock the kit, Have it running on my 90, not using their manifold of course but had absolutely no issues so far. HOWEVER....like others have stated, you've created a bomb that you have no way of controlling. if youre really wanting to run it use vvt 265 injectors, use the stock ecu, with a fmu. BUY A MEGASQUIRT. Pm me if you need help tuning. certified efi tuner here.

on which systems?
how many megasquirts have you tuned?
Seeing you post that you prefer speeduino over megasquirt in the other thread and then seeing this made me laugh.
