Few tuning ?s Gettin ready to do a cam install(F13 114 LSA, FAST 90, 01 injectors), and have a few tuning questions.
1. Im swapping 01 injectors for my 99 injectors. can i just copy a 00-02 fuel injector table? and is there anything else i need to change/copy?
2. Im also installing a FAST 90 intake/TB. is there any definate answer on what needs to be adjusted for that swap(goin from 99 LS1 intake)? I have tried searching, but what does come up seems to be mostly for vettes, and doesn't work right for an F-body.
3. Any prestart adjustments to idle, fuel, airflow that i need to change? Any relearn procedures that i need to do?
4. Does anybody have a decent tune for a F13 that i can use as a starting point?

1. yes you can just copy the table for the injectors that you are installing and do not mess with it again unless you change injectors again..
2. If you want to tune it, you are going to want to unplug MAF, copy high octane spark to low octane spark table. Drive, log/scan. Adjust VE table to get trims dialed in to slightly negative values. Plug MAF in, drive/scan, adjust MAF table to dial trims in. Then do WOT tuning via PE table(Wideband 02 sensor is great for this).
3. All fueling I described in step 2. You can chamge idle if you want. After reflashing it will take like an hour of driving for the trims to relearn.
4. I dont have a tune for that.
Be sure to search this forum and read the stickys. There is tons of info here on how to tune your ride. Good luck.
I am sure others will give you some advice as well.
