I'd like to get some input from you folks before I start tuning my engine timing.
What revolutions should it be at when at a standstill? 1200 rpm?
My neutral and Drive (standstill) RPMs are about 500 revolutions off from each other. That doesn't seem right so it's one hint that I...
So i have been reading about tuning an engine, and it almost seems too simple. I was hoping the veteran tuners out there would be able to fill in the blank spots.
I have come to understand tuning as this: when the amount of air going into the engine changes, the air to fuel ratios need to be...
Recently ordered these from DDM TUNING Oct 2. Recieved them in the mail today. I looked at the bulbs and notice they were not clear, they are rainbow (the kind of rainbow u see in a oil spill)
these bulbs are H3 3000k 35w
This is a log from a WOT run of a 2ZZ with the following mods (among others):
- MP62 supercharger with 2.65" pulley
- VisionFunction castings and A/A intercooler
- 80mm custom throttle body
- Piper stage 2 cams
This is a typical low-peak of A/F ratio when tipping-in with my setup. Tip-in enrichment is completely turned off. Observe that at tip-in A/F ratio destabilizes approximately for 1 sec and after very smooth depress of the throttle, A/F ratio destabilizes inversely for approximately 1 sec.
Since the installation of an A/A intercooler to my supercharged setups (both the MP62 and the TVS R1320), I had some issues with respect to idle and throttle opening rate vs. A/F ratios. To be honest, I had throttle opening rate vs. A/F ratios issues when I also had no intercooler at my...
