Nasty bug and code 47

[chuckmuska2005]

I know, code 47, there is no 47 that I could find but I tripple checked and it really is code 47. Here's my issue, my 1j is running rich, like below 11AFR. I have gone over the ecu and had the capacitors replaced, checked the harness for loose wires, checked the map sensor and fixed the knock cuz I got the code for it. I replaced the resistor pack for the MKIV 550's (cuz the jeccs one i got went bad) and noticed it ran much smoother but still rich. I got two engine codes, one for airflow meter and a code 47? Any ideas as to what's causing this?

My mods are:

single turbo
MKIV 550's set at 38psi
walbro pump on switch
APEXI NEO
AEM UEGO
All on soarer harness and ecu

I'm still lost can't figure this thing out.

Flow test your injectors? Any kind of tune?

I have the MKIV 550's on a safc tune, I'm honestly starting to suspect the injectors. How do I get them flow tested?

Not so worried about the flow test actually, wondering if the pintles are fried on the injectors. Starting to suspect ECU.

Check the capacitors in your ecu. Mine ecu is at Driftmotion right now for repair.
Here is the link for the repair service from Driftmotion.

I got the ecu back from Aaron at driftmotion less than a month ago for the capacitors to be replaced

Did you replace the o-rings like you mentioned earlier.

Try using the stock injectors if you have them.

Try leaning it out at idle till it is around 11.7 afr's. Then do a street tune, without going over 95% duty on the injectors. So no boosting and if that works, look at your injectors.
