M30 AFM+19lbs= WOW!

[Rob]

I came away from a so equipped 325i wholly unimpressed, but I'm glad you like it Bobby

[RCWells]

Well, I'll feel better about this whole fiasco once it's properly tuned, however and whenever that happens.

[Rob]

i actually just started to read this thread, bobby you need to do some modding ha

[RCWells]

Well since this thread stirred up so much shit, I may as well follow up with things as I go along.

I will be ordering the Apexi S-AFC II unit in the next few days, and I already have dyno time scheduled for March 4th, Baton Rouge, 9AM.

I will install the AFPR this week, and the 25mm MC as well (it's been on the shelf too long and while I'm doing all the mods, may as well finish this one too). Then, I have got to install a new clutch, and it's off to BR on Friday, March 3rd. Crash at Branden's, have a few Amberbocks and get up early for the dyno fun.

We'll see what happens. Should be fun. (and I mean that in a really r3v sort of way) .

I liked the mod because it helped me sell my motor faster :)
I swapped in an 027 AFM and it ran like dog shit. I had to put an m20 board in it for the motor to run correctly FWIW.
Just watch your costs Robert, dont spend the value of a MAF swap.

[CGDoig]

oh my god, after this thread i don't think i'm going to do it. Too much work for not much gain, and a chance to blow things up. Just like this thread.

You can run a MAF with an SAFC, don't bother tuning the M30 AFM with it.

[RCWells]

You can run a MAF with an SAFC, don't bother tuning the M30 AFM with it.

And you KNOW this because.....?

[Digitalwave]

Because thats why a lot of people buy SAFC's, to do MAF and MAP conversions. If you can do something good, why do a still-restrictive AFM instead of a MAF?

Robert,

Tj is correct with his post. It would be pointless to tune with a AFM if go with with a SAFC... you are better off going with a MAF/MAP sensor. AFM = barn door MAF/MAP = sensor (aka: no blockage)

[rwh11385]

and if you do a MAF swap, it'll make your "gain" from a M30 AFM look as gay as Elton John's christmas tree

[RCWells]

Look, I won't argue that point that MAF > afm. Not much point in that. BUT, unelss you've seen that the afm tuned with a safc is not effective firsthand proven with poor dyno results to back it up, then it's yet again, just more supposition on your part.

As of right now, I am NOT going to go with the Apexi unit. I've decided to just tune with the AFPR and leave it at that. IF I need to, later on add something, it would most likely be a MAF. I may do that eventually anyway. IF I had known that this would wind up being as involved as it is, I probably would have just waited and gone MAF to begin with.

No regrets though, this is a learning process, and I've already learned much. So, I am happy that I've gone ahead with this particular install.

Now, does anyone know how to or know where a good write-up is on the installation of the AFPR? I don't have any diagrams or instructions, but need to get this on ASAP. Oh, and Dave's site is not detailed enough to answer what I need to know.

that's the most logical decision


i think that is what i suggested too, lol. coincidence? haha

Wells, do you realize we are just trying to help you out? You don't have to get so defensive everytime we suggest something.

Good luck with the dyno tuning, I think you will be glad that you did it.

-I would just go with an MAP:
