****FOUND THE PROBLEM****

I'm cleaning up someone elses mess and they had set boost cut.... I never use it so didn't even think about it!
*****

I have been trying to help this guy tune his car remotely and we have things close, he is using coil on plug against my advice and already had one go completely bad.

Car boosts fine up until about 13 to 14 psi then does this weird up and down boost and AFR that you see in the log. Only thing I can think of is that these coils are garbage maybe and cutting out about 14?

Has bpr8es plugs gapped at .020 (thats what I was told)

Injectors also don't add up as he supposedly has 2200 Bosch but as we tune them they are closer to 1000s

Looking for any help. I'm doing this for him for free as he was ready to ditch the car (wasn't even running until I started with it). Another set of eyes is appreciated

Let me get my crystal ball...
The front 02 voltage is bizarre - .8v or .2v, and no cycling - I assume this is related to the narrow band simulator enabled for the wide-band?

A picture of the engine bay would go a long way to helping to know how the engine is configured.

The Speed Density map is a beautiful rainbow - no where near a stock starting point.

What kind of car is this? More details please.

I did the VE table, I know its pretty LOL

I'm an idiot. He had set boost cut to 14 and didn't tell me, I missed it, now it makes sense.

It looks like a boost limiter is set by intentionally cutting fuel. I don't use it in ECMLink so I am not so sure but isn't the option in the pic below the cause?
