so today i swapped another gsr into my del sol and it seems alright except that the vafc is acting up and my car seems to surge when i first get going. an example of my vafc2 being weird is say my car idles at 800rpms then i rev it to 1200rpms.. the vafc will read 1200 while my tach on my cluster reads back down to 800. the vafc worked fine with my old motor i dont know what is going on with it now. any thoughts?

thanks jon

 

Its showing your last and highest rev. on my vafc1 does the same thing, but you can turn that on and off. If you cant figure it out and its not tuned then just reset it.

 

yeah i was trying to figure out how to reset it because i dont have the manual
