Nitrous IAT is timing being pulled?! Ive used this on my tbss for yrs without issues. I have a customer vehicle tht we are doing the same to. I have it set in the tune to pull -8* on spray. I have iat wired to just disable it to -40*. Scanner shows iat jumping to -40* when armed but i cant get it to log actual timing being pulled. My total timing stays at 30*. I have even logged iat timing etc. Nothing changes. What do i need to look at to show actual timing being pulled??? Thanks.
You shouldnt have to log anything different to see timing being pulled. it will show in the normal timing pid. I'd start by pulling the tune in vehicle to make sure the iat setting actually went in. when doing the iat trick I always adjust the column to the left and right of target to match. That way if it actually falls in between 2 columns if the computer compensates up or down it hits what you want.

The tune settings are set up correctly. Im disabling the fiat sensor completely which jumps to the last column -38°. I havnt tried changing both columns next to each other. Tht could be the trick.
