Lean Idle Issues with Split Second AFC

Which Megasquirt, and who installed / tuned it ? I've heard of troubles trying to run OBDII w/ Megasquirt. My buddy is pretty nice with it though, E30 bimmer.
 
So there really isnt any way to change any settings on the SS AFC to compensate or correct this?
 
Dont mean to thread jack. DanDan what does the 626 manifold have to do with it? My car when i start it will deep but then idle correctly after i bleep the throttle didnt start until the manifold was put on. Jus tryin to get some information

it has no vtcs butterflies, i believe they shut to get more gas to the engine to help richin up alil bit. without the butterlies the manifold gets more air and leans out at startup, when its cold out my car actually dies sometimes and it hard to restart, i have just removed the butterfies from a stock protege manifold and ported and polished it, this should help with the issue a bit!

Cool thanks for the information. I now know why my car does this its was about 30 something here the other morning gave it gas and the car cut off but i know why .
 
I changed my settings to Over pressure or RPM and then set pressure to
1.1. It idles fine now. It was at -1 before. Problem solved.
 
I don't understand what you're saying. You changed 3 settings ? Isn't the "Over Pressure" suppossed to be set to 1.1 ? Whats does RPM have to do with it ?

Sorry, I have a hard time understanding what people mean when they type info. I used to do Technical Writing for a job, so I'm kind of obsessive when it comes to how people type, and the context lost in typing. Thanks
 
(over pressure or RPM) is one option for output B...

well actually its (Over RPM or Pressure) but same difference

EDIT: wait which pressure did u change from -1? the fuel pump start pressure?

Either way, I still don't get it. What you just said is kind of a contradiction. Regardless, it doesn't matter, as I'm just preparing for when I get my SS-AFC. I'm not big on searching through the 80 pages in the SS-AFC Thread for set-up info.
 
so you dont actually have the SSAFC yet? cuz that would be the problem, to understand what im saying you have to open the program, go to options, then output settings
and under output B there is a drop down menu that has 4 options
*Over RPM
*Over Pressure
*Over RPM or Pressure
*Over RPM and Pressure

and he is saying he chose the 3rd one and then changed the pressure (not sure which pressure, assuming fuel pump at start up) to 1.1, it is set at -1 standard
 
Correct. I run emanage. I've seen the R4 software screen-shots, but like I said I'm just trying to familiarize myself ahead of time.
 
I'll post a screenshot very soon explaining this in more detail. I am specifically talking about the boost pressure and the Output settings. Nothing to do with the fuel pump setting. It was at -1 psi which is the pressure when the AFC would "kick in". I now have it set at 1.1 psi which I believe is helping out the idle issue since it isn't acting up anymore. Like I said, I will post a screenshot. I guess I shouldn't assume people know exactly what I am talking about.

You are absolutely correct! I changed the over pressure setting. I'll post the screenshot tonight.
 
Just reading threw this and im trying to understand why people use the piggyback setups with a learning ecu? I come from the ford side of the world and piggybacks dont work on the ecu because it corrects what ever the piggyback tried to change. Im new to mazda world still and not really digged to much into whats out there for the ecu control. I know fords have the sct xcal's. They give you full controll of the entire ecu to reporgram it from ground up with no cutting or splicing of wires. Do we just not have somethen like that?

Also not trying to sound like a dick bag in this just wondering.

no we do not have anything like that as far as i know, and the ecu learns to a certain point with this piggyback, which they tell you to tune for
the only thing the ecu will learn, or try to do is even out the long term and short term fuel settings which is what you want it to do since when anyone tunes it its not perfect, and if it is well then the ecu will make sure its not LOL

its a great alternative to a full standalone, and people dont really make anything for these cars because there isnt as big of a market as evo's or hondas so we just have to settle with piggyback or overkill(standalone) for our cars
