Now that I got the my Talon back and running I started putting my toys in. I finished up the SAFC and EGT yesterday and got some wierd things from them both.
First the EGT works great I just don't know what to do with the information it gives me. On the way home with it I would get right around 1400 degrees just on regular freeway traveling. When I got on it with about 18 psi it would go up to 1600 and drop back down after a few minutes of regular driving. So this is pretty much new to me and any info would be greatly appreciated. Such as what is a popular temp range to tune to.
Secondly, after I got the SAFC installed I noticed one thing. It all works great, but the RPM's are off(I think). They read about 650 at idle, and my tach in the car says 1400, now I am not sure what I might have done wrong, but I verified all my wiring(solder and taped all joints), and wiring path and it is all good. The throttle position works, and I am assumig the knock counter works too. Currently I have all the settings zeroed due to this so nothing gets affected. I have did the initial setup as stated in the manual and for a four cylinder engine. I just can't figure it out.
Lastly, I am going to be putting in my PLX Wideband kit shortly and would like to know what a recommened A/F to tune to would be.
Thanks in advance.
