Actually, just re-readiing your post.. here's a note..
"Now it is very important to make sure your o2 sensor is working as this is the only sensor control mixture feed back. so leaded fuels are a no no.
I hope I can hear someone out there saying can it do individual cylinder tuning. GOOD because it can and does. Here's how it works
The PCM is told how far the o2 sensor is from the cylinder head and it is then given a time window of when it expects to see the exhaust from the last cylinder that fired. It knows which cylinder, from the firing order. At this point it expects to see that firer sequence in the time window while also calculating RPM that the tuner can set. When it does it can then adjust the mixture for that cylinder based of the o2 sensor."
Now from what I gatherd, the learning feature of the factory PCM can adjust each cylinder's AF ratio, based on Lambda readings at the o2 sensor to a preset ( by tuner ) lambda, as an end result.. So even though wackinig in bigger injectors may not be the be-all and end all, the capacity of the factory pcm to so finely tune the lambda, must surely be of benefit? Am I too far off track?? shall I grab another beer... I get smarter with each one!!!!!!
