AEM EMS help. MAF values rb20det

[1990typem]

Does anyone have the MAF values for a AEM EMS series 2 for either rb20det or rb25det?

Aem works with a MAF just doesn't have preloaded base values to work from. I've already spent 2k on the ecu and gauges so getting the map and iat sensor are out of the question for now. I just want it to run with the tune and the mods I have until I rebuild it this winter.
Mods are
Alexis intake
3" down pipe with open dump
3" blitz catback exhaust
Hicas delete

AEM does work with the MAF sensor but does not have any preloaded bases or values for the MAFsensor as switching to a map is more common. I spent all my money on this setup so it needs to work with a MAF for the next couple months.

I just need to see if someone has the MAF values to start building from but they are AEM specific

Here is a tip you might have to look into the RB25 file to find the maf value. The RB20 one is very incomplete. I had to copy stuff from that file to make my own start up. I didn't use the maf tho went straight to the map sensor.

That's what I've been trying to do but none of it is selectable. I'm trying to just build off info I've found for n60 mafs. Had I known the system was not actually plug and play I would have done the same but I bought a house so parts will not be an option for awhile

@ 1990typem, I've deleted your duplicate threads. You need to stay focused on a single thread in ONE forum. Duplicating stuff all over the place causes confusion, and won't aid in solving your problem.

1990 type m you might have to make your own. I just took a look and it's 0.5v so maybe useing the VQ map for the sensor you have. you might beable to use nistune and look at a vqmap.

I think it might just be easier for you to jump into the map sensor. it doesn't have to be a aem map sensor btw, you can use a GM 3 bar map sensor, take a look into the setup wizard to see the different map sensors.

[1990typem]

I don't want to and can't do a map sensor just yet. If I'd have known the aem ems was not plug and play I would have saved $1000 and bought a power FC. That being said I'm not going to have a ems sitting in my garage for 2 months when I know it's doable

Looks like your going to spend time making a vq map for your maf or getting a s13/s14 maf ka.

go yank off a 2 bar map sensor from any given turbo saab and a ait sensor from a late 90's vw...
running maf on an aem is silly, just get the sensors to convert to map and go from there...to spend the time developing the maf curve requires dyno access and time...lots and lots of time.

[1990typem]

I've already paid for the tune so the extra time to tune it is not a big deal because it's already paid for.

Sorry about that. I wasn't sure where to post it at

[1990typem]

So I ordered a gm map sensor, pigtail, ait sensor, and bung for the manifold from diyautotune.com. Now I just need to figure out the conversion procedure

[Carl H]

if you read the instructions its all in there...

[Yellow4g63]

Your going to add pins to your ecu harness with the pins they provided. Borrow or buy the crimper its very easy.

or junkyard up an ecu connector and use those pins/harness wire.
