Novice tuner here.
The car is an 06 manual gto:
Duspeed intake
Ls3/7 card maf with a saxon pc screen
Nw 102tb
Fast 102
Headers and full 3 inch exhaust
The ls2 itself is stock ( stock cam, stock heads )
Decided to get into tuning my own car because i had been through numerous shops in south florida and none of them worked out for me and my car. I have the tuning schools books on tuning; beginner and advanced. And i understand the basics
Adjust idle correction, dial in the fueltrims, add timing accordingly... but what i am trying to figure out is how to tune this 102/102 manifold/throttlebody combo.
The previous guy who tuned my car left the car with idle issues, when pulling out of gear and coasting the rpms would decelerate inconsistently slowing as it would return to target idle. And left me with a cruising AFR of 15-16. He blamed the lean condition on the fast 102/ nw 102. As a result ive decided to download an oem tune and start from scratch. But first thing is first, i need to tune the throttlebody before anything. How do i go about this?
On this forum, some say its all about recalculating the etc scaler and others say just adjust idle airflow and spark... so experts please chime in here and point me in the right direction with in depth explanations
Thank you
