AFC idle issue

Sure, I can do that tonight when I get back home!
The only differences i found was you have Auxilliary Coefficient B as 1 and the supermap has 0. I mean i guess that could be a problem if they use that input for something. but inside the actual database its all the same except that and you dont have a customer name.
i looked in a database program, so im looking at actuall data as opposed to the r4 software so im looking at reall data. If its not that aux coeff them im puzzled.
I just got a respond from mark at SS. Here what he suggested me to do:
Martin,
I recommend that you carefully clean the area around the connection for
the MAF signal wires both going into and out of the PSC1. Because the
signal operates in current mode, any leakage will reduce the signal
amplitude. Leakage due to contamination will have the biggest effect
at
idle.
This is a situation that is unique to certain Mazda applications. Most
MAF signals operate in voltage mode which is far less susceptible to
leakage. Let me know if this helps.
I dont get what I mean by cleaning up the connection though. Does he mean with an electronic cleaner or something?

I will try that at home tonight for sure! That might be the case... he said that this leakage could be caused by any dirt, contamination or corrosion around those connections, so I will give it a try for sure and see if it runs better. That makes sense for sure, just need to know if this is my problem hehe!

Ill check that for sure. Winter is bad here especially this year so there is a good chance that water got near the connections and rusted it or something.
indeed. mine leaks. i have to fix it sometime this summer. but i garage it and i heatshrink and silicone all my connections.
What are the wires for the MAF signal on the PSC1?
Are they the green for in and violet for out?
yea you are right.
update: I checked my wires and soldering and everything is good, i sprayed some cleaner on it and nothing has changed. I e-mailed him back just waiting on what he is going to say next.
Good... keep me updated once again!
yea so he e-mailed me back saying to check and see if the rpm and vacuum on the afc match the car/boost gauge. And it does so i told him that and just waiting to hear back from him again.
I don't know if they are going to warranty this or not but i'm pretty sure the unit has gone bad somehow.
dont forget the screen shots. id like to compare it to mine if u dont mind.
also, if u take out the afc, everything goes back to normal?
thanks
He asked me the same thing, but even if the vaccum was not read correctly it would still be under the over pressure settings (1psi) so the signal should not even be changed and technically run excatly as without the AFC.
