I fail to see how the size of the injectors will affect the enrichment value. Remember this is the percentage extra fuel of an already known quantity, added to compensate for improper vaporisation and condensation on the walls of the intake tract, valves and cyllinder walls.

 

Just so I can put this into "cody terms", the warmup enrichment table richens the fuel map by whatever percent is indicated correct? I did mess with this(put to 0 below 32 degrees), and it did help a little bit. My only solution right now is to pull the car into the heated shop for 20 minutes and she usually fires right up.

I think the MAIN cause for all of this is the 15w50 oil that I run; when its anywhere under 40 degrees its syrup. The engine cranks rather slowly unless its above 40 degrees(brand new battery as of yesturday morning actually)Ive always run this oil and Im a firm believer in it with "abused" setups, ie, what I do to my car everytime I drive it. I just want to get some solid #'s so I can put my car to sleep for the winter!

 

lol trust me, i know what it is.


the reason you dont run a huge amount of enrichment on injectors such as 880cc,1000cc,1600cc is because these injectors are so large, they are hard to open and close on such a small pulsewidth, thus idling it a tad richer seems to keep things rather smooth.

and with the full amount of enrichment, you will see super rich conditions during warmup.

 

This is true. I have 578cc injectors and they idle best at around 12.9:1 A/F.

Cold start enrichment is in the 10's and 11's.

 

I have 600cc and idle at 13.5. I was worry about it because was to low, now I am more calm

 

yep, you can thin out your warm up enrichment table a bit, try to get it back into the upper 12's atleast.

 

I'll work on that. First have to get the 2mm headgasket on and turn the boost up this spring. My map will change a lot once I get my 3.5 bar MAP sensor. At least that's what Cody told me.

 

Hows your gas millege with that rich of an idle? Is your cruising A/F still in the 14's?

Gas mileage is around 26 to 27 and my A/F's at cruise are around 14.2-14.5.
