'09 FEH MPG Techiques

Re: '09 FEH MPG Techiques
Since GaryG did not provide a reference to his statements or a photo of an aftermarket "tool" documenting/revealing timing is retarded after a cold start, we can only "guess" or look for such documentation. I have not found any such documention in the Helm manuals.
This is what I found at this link: http://www.patentgenius.com/patent/7762232.html
There is a lot of reading at this link. I do not know if this is what GaryG is referring to. In this link, at the top of where the invertor claims:
the first statement is exactly this:
The invention claimed is:
1. A method for a vehicle engine having a plurality of cylinders and an electric motor configured to rotate the engine, comprising: during engine idling, advancingspark timing of a cylinder to substantially before a peak torque timing, adjusting motor torque output of the electric motor to maintain engine idle speed, and retarding the spark timing of the cylinder toward the peak torque timing in response to adecrease in engine speed.
Note the filing date of November 6, 2008 and the date issued of July 27, 2010. Does this mean only the 2009 and newer hybrids have this feature?
There is too much other information to post it here. The engineers at this site can "eat their fill" here.

GaryG, the one and only!

Re: '09 FEH MPG Techiques
are people crying over the "warm up" strategy? I know my FEH does this. I can tell by the power the truck gives me and RPMs read out, when i get in and go.
So what's the issue?
I for one love the P&G tech. I just started using the "N" part on the glide... LOVE IT!

Re: '09 FEH MPG Techiques
In cold weather where the battery is too cold for EV but the engine is ready, I modify my glide using the brake pedal. The only way to heat the battery is by increasing the rate of charging. I find pulsing and gliding in "D" with a small amount of brake pedal pressure speeds up warming the battery to go EV.

Battery is not too cold for EV until the battery is lower than 0'F.
I know, because I've run in EV ( for short periods ) at 0'F.
Maybe you mis-spoke.
You don't get many amps at 0'F but you can for sure coast in EV and be in EV at stoplights at 0'F.
Only the engine and CAT converter needs to be hot enough to allow EV.

I do not think you have ever had this occur. At least not in a 2005-2008 FEH.

Glad you worked in P&G while driving the '09 FEH. Get that accelerator blip working and your set for some serious MPG.

No, he is the same poster! I was advised by the owner of Cleanmpg that gpsman1 uses the same URL to post. They have stopped him and have ban his post. The so called billyK can't post also!

They seem or made to seem like two different people.
