how do you guys like the apexi neo for tuning i had a split sec ftc1 and no one tunes them and if they do it costs a fortune on the dyno how do guys like this tuner

 

did you ever figure it out. i have to put mine in so i just wanted any tips you can give me!

 

the tach wire should be black/yellow in ECU E5 connector #16, and your in and out should be set to 13in and 13out from what i understand.

 

this is the thread i used to install my safcII in my gs400

i also set mine to 2 in, 2 out and it works perfectly....

my afr's were 11.8 to 11.2 @ WOT so far i have taken 17% fuel out and am now running a solid 13.2 to 13.5 @ WOT. im taking the car to teh track friday night to see if i have gained any significant power since my last trip (15.1 @ 96) im hoping for 99 maybe even 100mph traps!

 

this was easy you guys had me worried!

 

I was wondering are the wiring diagrams on the 400 same as 430?
