Intermittent faults are a bitch.
Next time out try going 100% TPS and see if the fault re-occurs.

Re: 4l60 no 4th gear
Shift points are governed by road speed and TPS. Make sure both of those are reading correctly first.

Re: Ecotec V6 Dry sump
Was interested to see if there are any high capacity v6 sumps anywhere and I found this mob. Not only do they mod v6 sumps to have scrapers and baffles, more oil etc... In the gallery I found a dry sump for ecotec :lol: http://www.asroilpans.com/holden-gallery.html I've got one in the garage, the r...

Re: Ecotec V6 Dry sump
That is certainly getting up there but then you are fixing all the evils with the dry sump.

Re: Ecotec V6 Dry sump
Holden V8's have a very shallow valve angle, unlike the Chevy 23° stuff which makes the drain back better but worse valve to bore angle. At the end of the day, I also don't think we are revving our engines high enough for windage to be a huge factor, it gets much worse the higher the RPM. What RPM d...

Re: Ecotec V6 Dry sump
My low oil pressure was on our L67 VX Commodore. Our street is uphill so you can brake a lot harder without locking up than on a flat surface. I wanted to find the point the tires would loose grip and the ABS would kick in. For the LS motors, I believe it's a design flaw in the block and it's someth...

Re: Ecotec V6 Dry sump
Came across this relevant video, the guy in it is really goofy but some interesting and surprising results with the oil windage. https://www.youtube.com/watch?v=bk7r0TL0Or4 I've watched a few of his videos, Definitely a interesting kinda guy. I think what that shows is they lack oil/windage control...

Re: Muggy high humidity days significantly improves performance - But how?
Probably need to measure EGT too to get a better idea of what is happening in the cylinder. The other thing that comes to mind is moisture changing the burn of the fuel. It's been a long time since I've looked at it but they used water injector on aircraft and it changed the fuel burn characteristic...

Re: Muggy high humidity days significantly improves performance - But how?
As you say, moisture in the air is supposed to be a bad thing but then why does water injection increase power? I remember my old 308 was really happy on cold mornings, especially when there was a bit of fog about, you could hear it in the exhaust note. Maybe it's the way you have it tuned? Factory ...
