Ok I'm getting the local honda dealership to install my SC in a couple days here.


Do I have anything to worry about concerning my AFR's? or is it setu pperfect from comptech?


P.s what about when I install my exhaust/test pipe....?

 

My understanding is:

Vortech - expect it to be lean out of the box, but you can buy recalibration kits to adjust
Comptech - expect it to be lean, but you can actually adjust it a small amount with a screw

 

^^ Do you mean rich? I know my out of the box Comptech definetly runs a little rich not lean.

 

I thought they set them rich out of the box for safety and then recommend it be set on a dyno to WOT AFR of ~12.5!

 

My tune has the top end a little lean, but i have a test pipe, my afr's dont look to great and i need to get something to tune the afr's

 

My CTSC w/ AC was lean out of the box. I had a CT header and Invidia exhaust installed.

 

How lean was it running? dangerously lean?

 

There you go!

Two set ups that are lean and not stock!

I called Comptech today to talk about fitting a Comptech and AC to a JDM car. They assured me, even with the higher compression ratio, that if I leave the car stock it will not run lean. It only leans out when you start tweaking They suggested if I'm going to tweak I need a custom ECU and map.
That's out side my comfort zone
