How to - Get an an AFC to work on the MSP

Any wattage resistor should be fine....

Does the FM clamp only work on partial load (or under boost), or it is always on....

I'm not really seeing how the ECU won't learn around this setup unless the O2 values are always being simulated...unless I just can't think right now...i dont know.
THe clamp ONLY works under boost, thats why we needed one with a pressure sensor.

Awesome, I might get an e-manage then. They're under $300, then all I'd need is the ignition harness and the stuff in this thread. Not too shabby! Thanks for putting the info in one place for us binary.

if you read the one thread you will also need injectors

the voltage clamp is on as long as the clamp is getting a vacuum signal. i suggest you rig it like this;

intake manifold - boost gauge line - T fitting (hose to clamp / hose to gauge)
 
Okay, I Know the clamp only works when the manifold pressure goes to positive.

Im trying to step by step this in my head...
the FM clamps it, so all the sensor sees is stoich, or what?
 
As orangezoom stated you'll all need higher flowing injectors if you want to run more than around stock boost. Tune away :)
 
how about a group buy for an O2 modifier, SAFCII, 440cc injectors, and whatever else we need. I'd be in for that.
 
Hrm. So, this works for boosted Protege's (MSP), but kinda curious if it would work with N/A Protege's for light tuning. I would assume you wouldn't need a voltage clamp, either, given that that only functions under boost, which an N/A car would very, very rarely see. ;) What with being naturally aspirated and all.

The other two problems I've seen for this are:

a) The comp not functioning under open loop operation.
b) The ECU relearning around the new device.

Out of curiosity, does it function on both of those situations? I couldn't see how it would work under open loop, as once you hit the loop, it just ignores the sensors totally, effectivly jamming it's fingers in its electronic ears and drowning out what it's hearing from said sensors with an obnoxious chant of "La, la, la, I CAN'T HEEEAAAR YOU!", for all intensive purposes.

I've obviously not yet slept, but I'm at work... I think I need sleep. *yawns* Just curious. =)

Werd. Its seeing a constant stoich condition.
 
I thought the SAFC just flat out didnt work at all, whereas the eManage worked, but the ECU would learn around it...

If it controls just fuel I do not think it will work, but that is what they said about the emanage too

Well, I mean, people have tried to get the SAFC working, right? And from what I recall, it just reads the RPM inputs or whatever. Doesn't really adjust s***. I dunno...if all it needed was a voltage clamp for the O2...it seems all too simple, especially with so many people trying to get affordable electronics engine tuning for the protege...
