I might just be one of those crazy mother f'ers who puts a stand alone on an NA. If so, what can it eliminate? I know the AFM can go, which is the main purpose for me, other than the added control. The TPS can go too right? How about the stock ECU? Does it have any purpose when using a stand alone? The reason I bring this up is, I recently found out that a friend of mine can get me a great deal, and I have basically run out of other stuff to get. I don't like body-kits or fancy wings and the like. So I figure if I want the most NA power possible, the road will eventually lead me to a stand-alone. Might as well get it while I can. Does anyone have any guesses as to how much gain there is by removing the AFM and having a custom aluminum pipe mated to the throttle body? The stand-alone will open up many of doors.

 

Most stand-alone EMS systems require:
1) TPS
2) air temp sensor
3) water/coolant temp sensor
4) load sensor (i.e. MAP sensor)

The Zenki TPS is not usable due to it's narrow-band design; this needs to be replaced by a full-range TPS.&nbsp The Kouki TPS can be kept, and the TPS signal tapped right off the sensor; this makes for an easier install.

Stock ECU can be removed.
All emissions can be removed - the stand-alone EMS implies no emissions.
If you own a Kouki car, you need to address the electronic oil metering system, since this cannot be controlled.

Just to give you an idea of what a stand-alone EMS unit can do, Grassroots Motorsports installed an Electromotive TEC-II onto a 1984-1985 GSL-SE with bolt-on mods.&nbsp The car managed to bang out a 13.5 down the 1/4-mile with some minor tuning!

Wow was that from stock port 13b? That thing should be putting out at least 200rwhp or is running on a high diet chassis.

 

I believe it was a stock block, but don't quote me on that.&nbsp It's a good idea on how restrictive the AFM is on an NA.

I've been saying it!!!!!

I've seen 1st gen with Holley setups do low 13's, now imagine what you can do with a Halltech?!?!? Iswear to god, a halltech will be my next major mod!!

 

These are very good things to hear. The stand alone is not a cheap mod but in the long run, it seems to make sense to me. Not only could the EMS help me out now, but in the future it will allow me to do things the stock ECU just can't handle. I look at it this way; I can spend $1500 on a decent set of wheels that actually slow the car down, or I can spend that money to add a good amount of power and have total control.

I don't need the OMP now, and I am trying as we speak to eliminate it. Loosing the AFM will aslo let you make a custom intake tube that can be nice and smooth. I have even considered maybe running the intake tube directly through the firewall, and mounting the filter under the dash area behind the glove box. Not sure if that will work but it would always draw cool clean air, and the tube would be about a foot shorter. I'm just digging up ideas right now and want to have a fully mapped out plan before I go spending a months pay.

 

RING!!! RING!!! RING!!! RING!!! RING!!! RING!!!

AND if you decide on going Turbo you already has the foundation for it!!! See, nobody listens to me!!

 

What brands of engine management systems are capable of working on a rotary. I know Wolf and Haltech, are there any others?

 

Microtech, Electromotive.........

 

SDS EM-3 if your willing to remove the CAS and install an 81-85 distributor and two coils. No flaming please, I've heard it all before.
