Would this give me similar benefits to a haltech? I wired up an s-afc in my friend's car today, and it was fairly simple, much easier i'm sure than a haltech. I saw a thread earlier about hot-wire mafs, supposedly miatas have the mafs insted of the afms it seems, if i used this s-afc with the maf would this possibly work? Thanks.

 

Define "work" ...

 

Use your own judgement of how i meant work.

 

I have some S-AFC expirence under my belt. It works great for NA cars. But obviously is no comparison to a real EMS, like the haltech that you mentioned. Hence my comment. It doesn't really control anything, it just plays with what the ecu sees. It has absolutely no control over timing, but you'd probably be keeping the stock distributor. Also, as I mentioned in the other hot-wire MAF thread, you most likely won't be able to just wire in the hot-wire maf.

Here's an Idea...If its within the control of the S-AFC (ie +/- 50% simulated air increase or decrease) you might be able to somehow hook-up your engine to the ecu from the miata, and then you'd be able to use the hot-wire MAF.

It would require a ton of research, and expirimentation to get either to run you engine, and run it well. And remember that the S-AFC is only good if you have someone that has the equipment and the know-how to tune it.

 

Basically i'm better off buying a haltech.

 

the safc might not work on a gsl-se because its not a 0-5v system, its 0-12v. someone needs to find out if the safc manipulates the input signal, or takes the input value makes its calcuations and outputs a 0-5v signal
