would it bwe wise to rid the afm, run powdercoated exhaust from the turbo to an aftermarket hks greddy or K&n filter? this with using silicone couplings and all of course

I don't exactly following you. You wanna ditch the AFM? What's going to reg. air/compressor? You need an AFM or a VPC (vein pressure converter) OR just get a stand alone ecu. Is this kinda your plan?
Let me add something to this. Has anyone stuck the AFM after the IC (on the way back to the TB)? I did that to my RX-7 until I bought a MoTec and it worked great. Granted MR2's don't have nearly the room to do this. Just a thought.
but you can disconnect your VAF... or Vane Air Flow Meter... its not called a AFM... Air Flow Meter... thats just what is does as well as sense temp. If it still runs it means you can remove it. Meaning the car is running off the MAP sensor. Your car is gonna run richer so w/o fuel management its... well... rich. Keep in mind tho... 9 outta 10 times its gonna throw a code. It might not since its an older car, like i said i don't know the turbo system that well.
In order to remove the code you'd have to get a re-flash.
so basically the answer to your question is no, its not wise to rid your AFM.
its a performance piece... senses air flow to know how much fuel to add. would you get a better flow w/o it?.... yes... enough to make a difference?... no. like he said if your gonna remove important ECU sensors your gonna need stand alone management. but w/ VAF in some system isn't needed because the ECU will rely on MAP sensor as a back up.
Was just curious... as it would make it easier to change and or clean the air filter.. I just remembered that in My Rx-7 I ran the filter directly off of the turbo. This is the reason I asked the question. But I figured there would be consequences to the thought. I saw that Hydes car didn't have one, but I imagine that with all of the money they have invested, that they gave the car a standalone unit... What do u all think about the apex'i power fc?

I don't like them personally. If you want affordable ECU get into the Wolf EMS V5 or 4.0. They can be bought for under 900.00 AU
Is the wolf EMS a presetup unit... do they program it for u when u cann and tell them what u have? I am just curious as to what the best unit is and why... I know that the power fc is a standalone unit not a piggyback... not that that matters to me or anything.. but I would just like to know what the best unit is, where I can program it from here in south florida, and the easiest one to use.... For example, UI would never tell anyone to purchase the Apex'i avcr boost controller, it may look Kewl, and give a presentation, but for 700.00
you could find yourself a nice manual boost controller, and buy all new suspension all the way around the car..... so I am looking for something that works, and is easy to program. Not that I am anywhere near purchasing a unit yet.
you take off intercooler... and put a air filter on the turbo's intake and another filter for the throttle body... but you still need the VAF sensor after the filter for the throttle body

It should matter
Best unit? MoTec, no question about that. However the TEC 3s is sweet too. Wolf, Hal's and Slinger's are all about the same
The Wolf EMS does not come with a preset program. If I were you stick with the oem ecu, there actually pretty good puters unless your running a huge turbo and want more control.
I'm not into the APexi light shows, but I didn't think they were stand alones. I could be wrong. I tuned my buddies GSX and his was indeed a piggy unit. It was okay I guess. If you go stand alone, MAKE SURE the local tuner knows what he's doing with the ECU you buy. I leaned the hard way, BUT, I learned it on my own. The first time I took the RX-7 to the dyno I pulled a 470rwhp @ 18psi w/ T70 turbo, so that wasn't to bad for tuning on the street, I won't ramble anymore, just keep it simple.
Yeah, I guess the factory ecu should be sufficient for me... I only really want 300 at the motor... which all I need at this point is an aftermarket IC and have the car setup to run properly and efficiently with reliability.. I have had extremely fast cars B4, But when u are pretty much faster than anything on the road u get bored of the racing... No challenge. Plus the faster u make the car, the lower the reliability goes.The main reason I bought this car wasn't so much for speed, but more a quick car. And my main focus this time is going to be looks, which is a huge and expensive endeavor.
If you eventually upgraded to a complete engine management system, then you will most likely no longer need it. Until then, it causes no problems, so why touch it?

It will not work on the MR2.
Again, it causes no problems where it is at, so why move it?

The turbo MR2s with an AFM do not use the MAP sensor for fueling.
A stand-alone system is only as good as the tuner who tunes it. A marginal EMS with a good tuner will be better than an awesome EMS with a crappy tuner. Shop for a competent tuner first, then get the EMS if you decide to go that route. I'm personally a fan of EMS's since there is much improvement to be made over the stock ecu and you can ditch the AFM. An EMS is not entirely necessary for your goals, but if you can afford it, it is a "cleaner" alternative to the various piggy back options and affords you a lot of flexibility going forward, assuming you have found a good tuner.
