Hey i installed the Apexi VAFC II in my prelude and it droped my rev limiter down to 6500 and when im running it in vtec for a while my engine check light comes on i have checked all my wiring and it seems ok and all the options are working on the unit????

 

ur ecu is in protection mode...

run the cel with one of those jumper wires to find out what u wired wrong...


( i just installed mine like 3 wks ago)

 

Sounds like you wired it up wrong, samething happened to me a while back. Check your wiring again. You most likely got the colors mixed up.

 

well i thought that i had wired it up wrong but i have re checked it twice now and i am confident that its ok.
the apexi website said i should look out for open connections so i went to the trouble to heat shrink all the connections as well so there isnt even a open wire.
but what do you mean by run the cel with one of those jumper wires??!? and is there anyway to get the ecu out of protection mode and would a wrong connection only put it into protection or could there be other ways.
thanks for taking the time to write back though because i have had this problem for a little bit and its really starting to get to me..

 

check youre sensor-settings on safc

 

did you follow the instructions closely regarding the placement of ground?

 

ok recheck the wiring diagram and make sure for a few of the wires... YOU CUT THEM and prevent them from goin to the ecu at all... ( it hin its the Blue VTM wire or something)


also, Check to make sure for i think 3 of the wires... U have to CUT the wire,, then hook up 1 wire to it.. and another wire to the OTHER half of it....

Not just tap into the connection like you have to do with the power/ground

thats what i did wrong

 

thanks for writing back ill re check my wiring again and make sure that i have cut the wires i needed to, i will let you know what happened

thanks again.

and about the sensor settings i think that there fine its like 6in and 6out isnt it??

 

hey i managed to pull the computer out again and i have rechecked the wiring over and over again i am now positive that the wiring is ok. what else could it be, my friend is lending me his VAFC II in two days and i will see if his works but if it dosent then i really dont know what to do.... so if anyway has any other theorys or have had the same problem please could you let me know

thanks in advance....

 

map sensor must be set on 6 and the arrow must be set in up-right position, if my memory don't lie to me.

connect safc on wire diagram without cut off speed limiter!!!

 

bump
please anyone out there with any other ideas???

yeah i did what it said with the ground wire i think it was the brown into the black then the black into the ground for the ecu
