3G MAF 482 - When to upgrade from 2G MAF?

[95GSTowner]

Profile is current and I just installed ECMLink V3 Lite. I've searched on the topic and I know the 3G 482 MAF is an upgrade but not sure when I would benefit from it? Today at the junk yard I came across a 3G MAF "482" from a montero sport. I read this MAF is considered to be as good as an EVO 8/9 MAF and is an upgrade. My question, is it even worth using in my current setup? My current setup is s16G 21-23 psi, PTE 680's, EVO IX Fuel Pump rewired. With ECMlink, The 3G MAF should be easy to tune but again not sure if I would gain anything.

Go speed density then you don't have to worry about the stupid maf.

Check this out for sd, ecmtuning.com read through this and youll find lots of information on options.

Not until you've reached about 50 lb/min of airflow. You'll won't get anywhere near that amount with the Small 16G, so you have nothing to worry about.

Ya I was right around 35-37 lb/min @ 19-20psi with my small 16g, 2g maf was never an issue.

thanks for the info. after searching most of the day all i could gather was that it's an upgrade. I have a spare 6-bolt block that i plan to build this spring. Will use 2g head on top. Also i'll be using a much larger turbo that i already have fp3065. At that point i'll upgrade from ecmlink lite to full so i can run SD.

I was at 475awhp and the 2G MAF was still working fine.

I've ran SD on my 2G, and I'm currently running it on my 1G -- it's a waste of a lot of extra time tuning. Why calculate airflow by screwing with VE tables when you can just measure it and not have to mess with anything? (no that's not actually a question, we don't need to fill this thread about how great SD supposedly is, as that would be off topic somewhat)

I dynoed with the tiny injen intake pipe, and then pulled it off, and only gained a couple hp at 400awhp. With a Holset or something that has a bigger inlet and more airflow, it definitely pays to get a bigger intake pipe (a MAF is not going to kill your hp because of a "restriction"). On a Holset WH1C, I saw over a 3 lb/min airflow gain going from the 2-1/4" intake pipe to a 4".

This is what I needed to hear! I'm good with a wrench but know nothing about tuning. My future power goal is 350whp - 400whp so it sounds like the 2G MAF can handle that. Thanks

You can run sd on lite.

Thanks for clearing that up. I was thinking of the gm-maf cable feature.
