AFC-SplitSecond PSC1 Map Library

[2.0t03speed]

any of you got a map for 565's ?

^^^ LOL, make your own! You could always try one of the 440 maps and go from there. You're going to need a scantool to tune in closed loop though.

thats gonna be a pain lol.. or at least tedious it seems.. GL

i think what im going to do is start with kickers 14 psi mad and adjust the fuel for the 565's since its only a 28% difference.

I'm suspecting that somewhere in one of the 2 wires that connect to the O2 sensor there is a short or disconnect somewhere. When the car starts up & idles, it should be running in closed loop mode, where it is reading signals from the primary O2 sensor & determining fuel output based on that reading. When my car is wired normal, the car idles fine & gives a AFR of ~14.5. When the AFC is connected (and thus is spliced into the O2 sensor wire between the AFC & sensor) I get the heavy "fuel dump"....since the AFC is not programmed to change anything with fuel until it goes into open loop mode (programmed at -0.81psi according to my map settings as read from the AFC last I checked) in theory it should still not be able to change any fuel settings when it is at 15in Hg vacuum (rough idle decreases the vacuum idle a bit)....so if the O2 sensor wires were shorted/disconnected in the AFC somewhere, it would not be reporting any value to the car ECU, and therefore the car would be (in my head) trying to compensate by adding more fuel to get it's expected AFR from the primary O2 sensor.

Does this sound right to you guys? Like I said, I've done alot of reading & if the AFC behaves the way I understand it, it's really not changing anything...it's just that the ECU isn't seeing the signal it wants to see & therefore is acting haywire to try to adjust.

EDIT - also, can I connect just the Black, Red & Yellow/Black wires and not the MAF or O2 wires to see if I can monitor things without actually having the AFC interfere with anything? Also, could the unit likewise be wired with the above setup & just MAF wiring (not connecting the O2 wires) to again test if the unit is functioning properly. In a sense....can I do this kinda wiring & in turn test my theory that the O2 wires to the AFC are in some way compromised?

O2 sensor weak ground, any disruption (installation of SS-AFC put your ecu grounding system at its limits) of the o2 ground will cause an issue (output a full .9mV super rich - vehicle will try to lean it out),an O2 element creates voltage (the reference for it is the ground - mess with the ground the element has nothing to bring the voltage back down with),

testing : with an ohm meter and volt meter, measure resistance from engine block to neg battery should not exceed 15 Ohms, also take a voltage reading with vehicle off, from the battery terminals say its 12.3 volts..... Take a reading from the positive terminal on battery to (ground) the engine block, difference should not be greater than 1 volt.

Also, Take a reading from the positive terminal on battery to (ground) the ecu ground by the drivers side strut tower bolt with a white multi-connector, difference should not be greater than .5 volt.

If it is check ground connections, clean connections, you may have to use a wire brush on the eyelets of the washer-wire connectors.

Unless there is a breach in the connections inside your AFC, that could cause some back feed causing similar symptoms, but I would assume the unit wouldn't power up if that were the case.

Wow, very helpful information, i wouldn't doubt that this is the cause of most of our idling problems and other such things. thanks for posting, my car runs fine but i might just make a separate ground wire for the ssafc just to put some of the stress off the ecu. I also noticed that when i didn't have a very good connection with my battery terminal (the ring was not tightening all the way) so i put a copper piece of sheet metal around it, works great, and car ran much better after that.

got a picture? there's a lot of ground wires connected there

does anyone have a map for my mods? im not goin through all 44 pages

I'll take some pics today.

mostly you have to just use the supermap and adjust it on your own, but once i get my ATP wastegate put in and fixed, (hopefully this weekend) than i can finally finish adjusting my maps, can prob. use mine, but even then you would need to monitor and adjust as necessary for your own purposes.. everyone is different.. even with the same mods.

anyone got a copy of the installation instructions... im trying to figure out what wire and pin number the tach is on

 

[sean22306]

"7) T-tap the PSC1 YELLOW/BLACK wire to the Lavender/Grey wire on ECU connector pin 48. This is the tachometer signal wire"

 

[SpeedAdiction20]

derekb, just saw that you have a FMIC, so ya wouldn't be able to use my map well lol, just start with the FMIC one in here, and adjust it, gonna need the WB though and i like the datalogging myself, makes things much much easier and safer.

as far as looking for the instructions, look at the How To: on this, i think they moved it to how to section, but check both areas just encase.. or actually here i have it listed so ill just link it, but they have the attached instructions.

All i get is bir red x's instead of pictures... it's like that for all the ssafc instructions here... i think whomever hosted them is no longer hosting them... there is one link that has the pic but it only shows the top section...

Exactly the info i was looking for.... thank you much

 

[rooster]

yey! my lean problems have been fixed, input coeficients weren't filled in correctly.

 

[SpeedAdiction20]

lol grats.. oh ya i just noticed that there wasn't a pic there anymore, i guess ill take a pic of them sometime and stick them in here if i get a good one.

 

[axisboldaslove]

does the splitsecond take readings from exhaust 02 sensor....i currently don't have mine plugged in and just wondering if this would be a problem for this product???

 

[derekb727]

does the ss afc v1 take away the speed limiter?

 

[SpeedAdiction20]

pretty sure no it does not take the speed limiter away, and no it does not take readings from that O2 sensor, just the first, primary one in the exhaust mani

 

[derekb727]

wat do you have t do to take the speed limiter away?
