Tunning from nos to n/a

[pursuit2550]

I spoke to a reputable tuner the other day and he told me that to change fro a nos tune to a n/a all I had to do was increase the timming table. Is this all it takes? I dont run nos very offten so I would like to run on a n/a tune most of the time, so if that the only difference then that would be nice.

are you asking that you want to run nitrous ..but u want to run NA tune most of the time.. and you don't want to run between tunes .. ?

if that is the case... its best to run WET system ..get your self a timing retard device if you did this u can run ur car NA tune all the time ... and once you hit that bottom your wet system shall take car of ur AFR ... and timing device shall retard the timing to a safe level ..

No, I will run the nos tune when I go to the track and then just switch back to the n/a tune.

Where would I go to add just timing?

If you don't know how to adjust a timing table, you need to do a lot of reading before you start making changes to your tune.

To answer your question - download a stock tune for your car from the repository. Then open the current tune in your car. Do a compare with the stock tune. Copy the HO and LO spark advance tables and past them to your current tune. Save it with a new name and upload it to the ECM. This ASSUMES that your car is stock and that the stock ignition advance table is still applicable to your car. You need to know if this is true BEFORE you make changes.
