Default Running Super Rich. Correct maf sensor??

Hey all. I recently finished up the turbo swap on my 92 240 wagon complete with a fresh bottom end, and t5 swap. Sense I did the swap I've had a pretty consistent rich condition (pegs the aem gauge at the minimum 8.49) and a hard shudder under acceleration. I've done a little reading and it seems I may have the incorrect maf for my setup. I have the 0280212016 maf that came off the car when it was Na. after some light reading it seems I need the 0280212007 out of a 1990s 740 turbo. Before I go and throw down some money to get one coming I figured it would be best to consults the pros and make sure the 007 maf will fix this issue.

I have the 3bar regulator and the orange injectors running around 15psi

The 016 in there is correct for your car. The 007 is an LH2.2 MAF and is not correct, also will not be from a 90's anything for Volvo.

Does it run rich cold? hot? always? I'd suspect bad MAF sensor or massive boost leak first.

I swapped out the ecu and timing box when I did the turbo swap with a 91 turbo 740. It is consistently rich. I have checked for boost leaks but haven't been able to find anything major. It seems to run a little better when the engine is cold but not much.

I have two other mafs that I have tried both are the 016 and have yield the same rich condition.

You sure you used the right ecu? I believe the number on it should end in 563 or 937.

Did you remove the the WOT wire on the TPS? Believe it's the blue and white wire on position 3.

For starters just remove it from the plug and see if it helps. If so terminate the sucker and drive.

I will go give that a try and grab the number off the ecu.

Google tells me that's a turbo ecu with egr. Should work (I think) but it might be unhappy with the lack of egr. Do the wot wire thing.

Removed the wire and the rich condition and chugging remained unchanged.

In my bit of reading about that ecu, it should work but the cel will stay on.

Did you install high-z injectors or a resistor pack?

He said it had a stock 016 amm and is a 92 so I assume lh2.4 which would have the resistor pack to match the injectors on the donor engine. Should be at least running the b230f/t green injectors.

The NA engines don't have a resistor pack? Unless I misread what you're saying.

The chugging could be spark blowout from too large of a plug gap. Check your plugs and reduce the plug gap to .026". I'd also check the engine coolant temp sensor and make sure it's working. If that sensor is open circuit or too high a resistance it can make the engine run rich all the time because the engine will never go into closed loop operation.

Is this the same sensor that will send a signal to the gage?

Nope, but the sensor is near the gauge one. You're looking for a sensor under the intake that has an injector style connector on it. The body will be black plastic and brass.
