hi
what is the real difference between safc, haltech, microtech and wold3d

i plan 350-400 rwhp so what's the best ems and turbo kit for me?

please tell me your opinion

zyounker

AFC is a piggy back and is not a ECU in it self. It just modifies singles going to the stock ECU.


The others listed control fuel, timming, have better resolution and features. They all replace the stock ECU.



As for whats best? find someone in your area who can tune one of the standalones listed and that is your best.


Having a tuner that is familar with your ecu and rotaries is the key ingrediant.

RETed

See above.

How about telling us more about your car?
I doubt you can afford "best"?

If you're asking about a stand-alone EMS, you cannot do it yourself.
If you insist on going stand-alone EMS, DO YOUR RESEARCH FIRST.
There are Haltech, Microtech, and Wolf3D subsections in this forum - GO READ THEM.

what is the most hp i can reach with SAFC? with all other setup like
fcd, 720 sec, walbro, mbc, etc?
is it easy to tune correctly the safc with AFR gauge?

and how it's difficult to tune an ems with just a wideband?

i read about ems but its hard to find information

thanx for your repply
it's very in my country to find other people who own rx7
i like this forum

Well, by the questions you are asking. you really should have someone else tune your car.. I mean you could probably use a base map or SAFC and just tune fuel on most of the systems using a wideband, but there is still a learning curve with that and that is also only tuning fuel. Timming is very important and very hard to tune and mistakes are costly.



Even if you have to drive a few hours to get your car tuned spending the money to do it is less then buying a new engine if you blow yours up.



A narrow band AFR guage that uses your stock O2 sensor is pretty much worthless. Dont use it for tunning.


Hope that helps.

The S-AFC is a piggyback fuel control unit made by Apexi.
The Wolf3D is a standalone engine management system made by AEM of Austraila.
Haltech and Microtech are manufacturers of engine management systems and components.

Engine Management System = Controls fuel flow, ignition timing, and some other secondary functions.
Fuel control unit = Controls the fuel flow and some other secondary functions, but not ignition timing.
Piggyback = Attaches to your car's stock computer, rather than replacing it.
Standalone = Replaces your car's computer.

You need to ask your local Mazda performance shop. This is not a project that you can plan on your own.

ok but
i think i will go with SAFC2

can i tune it just with the afr gauges or i need absolutly a wideband?

and for the timing is it affect with the SAFC? the CAS work fine!?

yes i know this shop but they just sell safc by catalog order!

they have no dyno and they don't know anything about EMS !

RETed

You think most places are stocking vendors?
You'd be surprised.


You don't need a dyno to tune a fuel computer.
If you really want, get a cheap wide-band that's really popular in here.


-Ted

alex144407

yes they just stocking vendors in my region !!

for example in my region of approximatly 250000 of people
i am the only one i know who drive a t2
but...

how much for a cheap wide band ?

and where do you got this information Evil aviator?

zyounker

you can get widebands for ~$350USD now adays.. Check www.rx7store.net for one vendor.

As RETed stated, a dyno is not required for tuning. You would want to dyno tune if you raced competitively, but it is not necessary for street tuning. I know of several people who have had great success tuning their engines without a dyno or wideband O2 sensor, although the kicker is that they knew what they were doing.

There is somebody, somewhere, in your area who can tune an engine. I don't mean this in a bad way, but I don't think that your knowledge is sufficient at this time. You can certainly experiment with tuning if you like, but you need to understand that your mistakes could very well result in a blown engine (about $2,000 to $3,000 CAN worth of damage). I just wanted you to understand this, because I have seen far too many people on this forum attempt engine tuning because the internet made it sound easy, and then blow their engine or never get their EMS working properly. It is extremely difficult to trouble-shoot EMS problems via the internet or telephone, so do not rely on these sources to help you. As long as you understand the risk, I think it would be a great idea to try things yourself, although some education and/or supervision would greatly help. A simple piggyback fuel computer like the S-AFC would be a good start for a beginner, or for a professional who is not familiar with rotary engines.

I just make it up. Aviators do that a lot.

OK, seriously, I don't know what information you mean. My tuning/EMS information is based on personal experience, college education, and interaction with tuners. My internet and regional information is based on internet search engines (mostly Yahoo), travel experiences, and interaction with various people. These are all things that anybody can do.

A steep hill to go up is helpful too, you're less likely to have to explain to the cops why you were doing 120mph.
