Anyone have the Mitsubishi part numbers for the 3g/Evo Mass air flow sensor?

My 2g died. Well it literally broke from heat and over tightening the clamp on it and got sucked up into my compressor wheel and beat up my brand new FP 68hta. So I figured if I'm replacing it I might as well upgrade. But looking through RockAuto. There seems to be different part numbers depending on if I look up an EVO or a 3G. There's also (4cyl 3g and 6cyl 3g) So there seems to be some difference between them?

Which one/year should I get that works the best? Tuning isn't an issue I have Ceddy Mods and there's an easy setting to switch to it. And I'll pick up a pigtail on eBay.

Also I currently have a K&N Cone Filter on my 2g MAF will it still fit/switch over to the 3g/EVO?
And the aftermarket air intake tube between the MAF and turbo, will that match up as well?

Thanks to whom may know these answers LOL
 
You’ll want the MAF with either “399” or “482” on the sticker. The 399 MAF is the actual EVO unit. The 482 was used in some Eclipses and Monteros and the flow and calibration are (supposedly) nearly identical to the 399.
 
I run a 339. There's a couple pics on my build page here: https://www.dsmtuners.com/threads/1991-tsi-awd.540276/post-153905477
You will need a different intake snorkle or adapter. The 3g/EVO maf uses a round outlet to the turbo and 2g is oval. Fits a 1g no problem though.
Here's the air filter side if you need measurements.

I got the physical setup done and car is running. But having some weird load issues in logging that's also causing less performance cause the extra LOAD is causing timing to be pulled when it otherwise wouldn't be. I know I have the MAF Size correct and MAF scaling I found off a Evo8 ECUFlash ROM. But I've been getting conflicting views on what the MAF Adder should be. Its been set to "stock" aka 2g MAF settings until now. I changed it to unit8 - 140 units. vs the 80 g/s the stock settings are.

Any body have a definitive answer on the MAF scaling and MAF adder settings for a EVO MAF on a 2g ECUFlash ECU?
