Need help with a NOS tune

[Luweegy]

I've got a tuned LS6 Attachment 24018 Can someone help with a wet plate 100-150 shot tune?

Start with 12 degrees of timing from 0.60 cylinder airmass and higher and 2800 rpm and up.

Add 10% fuel from 2800 and up in the Power Enrichment EQ Ratio vs. RPM table. Also in the PE Enable Cold TPS table make it 36% from 2800 rpm to 4000 rpm.

First do a pull from 2500 rpm to 4500 rpm and then check for KR and AFR. If its learner then 12.0 AFR add some more fuel to the PE table. Next do a pull to 5500 rpm and the check again for KR and AFR. Next do a pull up to 6500 rpm and then check for KR and AFR. After the third run you can start adding timing, go up 2 degrees at a time. You probally end up around 18 degrees of timing with a 100 shot.

All I did was take out 5* of timing in the tune, and leave it at that... If it's a wet kit, you'll mess with your fueling through the jets.

Got anothe ? What color wire am I looking for off the TPS on a 01 Vette?And what wire color and posisiton on the PCM is the tach signal.I'm all wired except for this and don't have a C% GM manual anymore for some reason.It must've gotten legs. Thanx again for the help. DSteak,5% degrees across the whole main timing table?

I don't know the wire for the TPS off hand... I don't have nitrous in my own car, and have never installed one... Just tuned for it.

When I tune a car, I zero out the AFR spark correction table and make all of my timing adjustments in the main table. If the same car goes back and gets a wet kit installed, I use the AFR spark correction table to take out however much timing I want. For example... I just did a 2010 Camaro that had a cam and heads, and after it was tuned, he put a 125-shot of nitrous on, so I just put -5 in the entire AFR spark correction table from 3200rpm and higher (window switch was set for 3000rpm and it's on a progressor).
