My Tuning history:
1. Fixed HKS 264/272 cam, can't get idle.
2. Fixed adjustable cam pulley, dialed intake and exhaust cam, good idling.
3. Low rpm very bad, I advanced ignition timing, so far so good..
4. High rpm need more fuel, meaning need Webber to do re-jetting.
5. Power? Fun but not as good as my PS SR20DE Tomei/HKS...he.he. but nice to hear it's Webber sound
6. Comparison:
On Webber engine, tuning your fueling is a bit dificult coz it will need a series of jetting kit to suit your engine needs but cost is cheaper compare to EFi tuning. The only hassle is to test a jetting one by
On my PS SR20DE, I've a PS Fuel Enhancer II to do my fuel tuning just from my finger tip located on my dashboard and a good point is I can tune while driving, meaning that actual load is applied. A PS Air Fuel Analyzer is helping me to show for an optimum A/F ratio, while you probably need a wideband O2 gadget for Webber engine.
