SAFC Wiring

[Rendon LX-i]

What he means what is it used for..

Well it tricks your map to spit more fuel to w/e your set the S-AFC at. which for boosted apps Roach you would need to run more fuel so you would dail in a lower percent ratio on the afc thus tricking the map to spit more petro. has a hi and low setting so when your just at regular driving matters w/e you set on your low is what it well go to..on the other hand you got the high which is when you get WOT it shoots what you put. i have both hi/low the same...theres no need to get all fancy with doing all the other bs. Works great at first my car would shot out craps load of snoot and not run. its a cool little unit if you keep your obd0 setup...which i wouldnt..

Yet you can use the S-afc on your obd1 to fine tune inbetween the gaps that the chip burning couldnt get. works good either way as a piggy back or a kinda alike a standalone...

Makes sense? all it uses is your map for tuning.

Thanks for the explanation Josh, yes I was reading on it and found out what it was used for.

I actually was wondering if anyone besides apexi made them, it seems not. Anyway thanks for the answers.

HAha i found my notes... here it goes pimping i wrote this reading and reading reading and reading before i boosted and i doted shit down...

For 86 accord lxi

Connector A

Brown/Black.....Ground 1 Cm from each other
White/yellow.....RED (powa input

Connector B

Red/Blue.....Blue(Oxy Sensor B) Air/fuel raio seen in voltage. usefull for tuning. can be seen on sensor check.

Connector C

White/Blue...Map Sensor
Red/Yellow.....TPS

SO pins are

A16..ground
A17 ..Powa

C11..Map
C7..Tps...

K now with some helpfull info i wrote also idk where i got it from but i have it here on my note pad and just typing.

Things you need to know

Safc setting
50% lo-hi throttle atmost all the way accross (to bout 4,500RPM)

Make sure SAFC is set at "PRESSURE" and set on 06in-06out Also make sure it is set at "/" in the car section

The common scale for injectoers are:
5%-440cc-450cc
4%-390cc
3%-310cc

Then Subtract 1% per 500RPM incresement. This well give you the starting point. To play it safe run Rich/Stoich side, so we increase fuel flow by 1% per 1000Rpms. Try no to top out 5%........because your fule maps are increasing in pluse duration and percantage at teh sametime.

So base setting for 450cc are
1 240/450 = 0.53
2 0.53 - 1 = 0.46
3 -0.46 + 100 = -46


So we have the difference of 46%. we add our 5% for injector compensation which leaves us with these setting.

1000 - 40%
1500 - 40%
2000 - 29%
3000 - 38%
4000 - 37%
5000 - 35%
6000 - 34%
____________________________Accord^
7000 - 34%
8000 - 33%/34%

Cross over can be set -45 low and -30 for your high all this does is determen when the low an high setting kick in. if they are the same then it wouldnt matter where you have this crossover set at.

Throttle point at 10% and at 13% for fuel economy lol which i never tounched but BUT THATS ITs if you connect it like that my ran like a dream and gave me a base start and was boosting a health 8psi all day everyday for 8 mouths yo...


Hope i helped for those are struggling with this ummmm TDURR haaha

[Tdurr]

^^ lol thanks. I haven't really messed with it too much. I need to get the 450's in so i can play with it for real.

thank you for this dude. for real thanks. i now know how im gonna tune mine.

[Rendon LX-i]

NO problem guys...I did it to save you the hassle....

[Tdurr]

want to know something, i still dont fully under stand the %thing but i know how it works and wut to do to tune it lol.

[b20a86lude]

hey can i c pics if exactly where u wired it i can think of wat ur talking about

[89T]

at the ecu...

[b20a86lude]

hey i want pix

back from the dead...so rendon are the numbers ive highlighted in bold, are they NEGATIVE values? im about to finish this off finally and I wanna make sure I do it right haha

[Tdurr]

The negative is for using 450cc injectors for boost. If you will be na all you have to do it get the settings right then leave it at zero. But really, go obd1.

Im gonna be running dsm blutop 450's so negative setting for me! Tbh I would prefrr obd1 but that just means im a little further away from finally boosting this old girl. It is on my agenda tho. God I have so much work to do

['A20A3']

I still need to setup the msd btm as well. Still need a few more parts too. Spark plugs are two steps colder than stock too IIRC

[Tdurr]

Spark plugs - ngk bpr7es. I remember that by heart because I fouled out so mmany lol.

And do obd1 first. It will get rid of the btm, and u can justbget it tuned from the rip. Obd1 on na makes a huge difference in its self.
