Why is it that all the car companies went to the wide
LSA cams shortly after we went to injection... I am sure
there is a logical reason... if they wanted to cover up
the idle with the electronics they wouldnt have wasted all
that money going to the wide LSA cams
Like Streetwize already said.........you don't NEED a lot of overlap with EFI because the fuel delivery system is way more efficient, heads are better, EVERYTHING is better these days. How many stock and super stock guys you see now running 102 LSA cams like used to be common. Things change, we are smarter and realize you don't have to crutch the motor with a poor cam design. So they are not trying to COVER UP anything. They are using what works BETTER for both idle quality AND power. That still doesn't change the discussion here and that is with PROPER tuning, the ECU doesn't care about the cam. You can MAKE it work
I understand that you can inject the fuel at the last given moment
to help correct... but the valve is still doing the same thing...
if the O2 thinks its seeing a lean condition the next cycle will
have more fuel applied.. so in reality its chasing the last cycle
but if the overlap is minimal then it wouldnt be.... JMO... I'm
still having idle problems of going fat(before I pulled the engine
the last time)... maybe I just have the idle set to low based on what
some are showing... I figured 850-900 would be a real number... but
I also have to get the temp up higher for this to learn... above
about 1300 things come around... this is on a 105 LSA installed
at the same thing
EDIT
it could be as simple as to cold of plugs.. 3923... this time
I'm going to 3924
