Unhappy s-afc ,ce light help...

well...i just installed an apexi s-afc today. i followed the instructions to the word. since i did not have a sodering gun, i opted for crimping it. there were no odors coming from the ecu, or the engine bay, and everything sounds and feels good. except... i now have a CE light. i followed the instructions from scooymods.com as a guide.

any help to fix this problem would be greatly appreciated. also if anyone has the correct settings for a MY01 it would be of great help.

you shouldn't get a ce light with a SAFC. try to reset your ecu and see if it goes away.

Default safc,ce light...

imprezakid,
i tried reseting the ecu,no go. correct me if i am wrong , but the way you reset is disconnect neg. battery terminal for about 10 min. then start car without hitting gas till it comes up to normal operating temp. then shut it off and start the car again. if i am wrong tell me the correct manner. thanx

yep, thats the right way how to reset the ecu. when i installed my AFC i got a ce light because i hooked up a wire worng after i corrected it and reset the ecu it was gone. you should double check to see if you have all the wiring right. also you might want to get a code pulled to see whats causing the ce light.

Default s-afc,ce light help...

ok, i just came from the local mechanic. he ran a diagnostic check and found the problem. i messed up, hopefully not too bad. according to the reading it said MAP wire was shorted . i should have listened to my gut feeling on this one, because when i got to this wire i did not know what to do. there was a map in/ map out wiremeachanic said i proably put the wires backwards.i'll find out soon enough what the deal is. this is just a heads up for anyone out there that is going to install a s-afc. double check your wires and if your new at this have someone who has a clue to help.

I have a MY99 and on the diagram it says B136 #5 for the MAF/MAP wires right? My question is that on the S-AFC there is a white and yellow and on ecu is Pink and Blue. So which wires do you solder together? White with yellow and yellow with pink?

Default s-afc,ce light help...

wrc, the ecu wire is pink and blue. what i did since i dont have a sodering gun was, i cut the pink and blue wire and spliced the male fitting closer to the ecu side. on the other end of the pink and blue wire i spliced the female fitting. the yellow wire should go to one end and the white to the other. and thats all she wrote. i hope this helps...

I think I understand. I havent attempted to install it yet but what your saying is that there is 1 wire from ecu which is pink/blue and there are 2 wires(yellow,white) coming from s-afc? And so connect one wire from afc to one end and connect the other wire to the other end?

PLEASE! go get a soldering iron, and some solder.

when working with something as delicate as these little ECU wires, they should not be crimped.

I also made that mistake once, because I knew it was only temporary. And sure enough, the CE light went on. I didn't have anything hooked up to the chip, I had previously tried to install something, but then since took it out, and was going back to stock. but when i crimped, the CE light came on easily.

when I soldered, I haven't had a problem since...

wrc555, correct the male fitting goes on the end of the pink and blue wire closest to the ecu(by the connection) and the yellow asfc wire should fit right in. the female connection goes on the other end of the pink and blue wire, and the white wire should as well fit in correctly. i hope this helps.

jgard18, thats my next move. i am going to get a soldering gun and solder the wires together.
