It is the stock housing (inasmuch as it is original to the car.) If you want dimensions, I can measure openings with caliper.

I think you are both correct. I think that Dacz is probably correct or at least on the right track about the car running on default/learned values after MAF error is posted. k0mpresd you are right on about the clearing codes clears the adaptations.

This setup is working passably as a daily driver because the ECU does not know the increased flow rate of the injectors. The increased air coming through is being mixed with more fuel than stock injectors would have provided and the happy accident is that it works well enough to get by until I can pursue a more resolved solution on both fronts (MAF and injector calibrations). I am wondering if the OE/stock 30V ECU air/fuel/load maps will be a good start if the baselines for the MAF and fuel injectors are updated, or is that not how it works? In my neophyte brain case, I imagine that since the SC boosts air flow in a near direct relationship to engine speed, the air/fuel/load maps would be be pretty close to what would be optimal, except that the scale applied to air and fuel calculations would be greater from idle.

Perhaps tonight I can look at the bins again and once more try to get that toehold of understanding that would make this communication easier from your end and more productive for me towards a better resolved solution. I really appreciate the interest you both have applied towards this.

Cheers,

add map, minus n75. seems like a giant can of worms.

have you managed to read your flash? Are you running a stock file?
