everytime i start my car in the morning and i press on the accelerator the a/f reads 16.00 and it cuts out real bad. once the car runs for about a minute the cutout goes away, but when it idles when cold the a/f is ok. what would cause this?

 

Throttle pump coolant correction factor, maybe?

 

I have no idea how to adjust the throttle pump map. I just looked at it a few days ago and figured id ask before i started messing with it.

 

how about the coolant correction map? stock cars generally run a little richer when they are cold

 

Well, i thought that but why would it run ok at idle and cut out only when you give it gas? Adjusting the coolant correction map will richen/lean everything overall causing the car to stall and idle rich.

 

anyone know how to adjust this??

 

you change the number.
lol

 

fire up the car, preferably cold, go to the "coolant correction map" hit "home" and make the number bigger until it runs better. as the car warms up it'll go thru different bars.

the stock ecu is 0 correction after 65C, so should you

 

thanks you asshat lol


ok, i will try this thanks!

 

i think this is for E6x? When i go to the coolant correction map and press home it doesn't do anything. Where do the throttle pump settings need to be? I've been messing with the coolant factor for the throttle pump and when i dropped it to 0 it got better, but thats the lowest setting i can go.

 

if you dropped the coolant correction factor # to zero and it got better, that means everything is too rich... lowering the number reduces the amount of fuel that is added in by the accelerator pumps when you stab the throttle. increasing the number increases the fuel.
this is on the accelerator pump (throttle pumps) page BTW.
the accelerator pumps really only work when you stab the throttle or there are quick changes in the map signal (like too quick for the MAP sensor to recognize it) so it reads off of the TPS.
i dont think this is the problem unless it's only doing the lean hesitation when you stab the throttle.

i think you need to check out the fuel coolant correction page like j9fd3s said. and pressing the home button wont do anything on this page because it's only one range. the little arrow should show you which bar you're at in the fuel coolant map at that current moment in time, so just mess with the bar the arrow is on until you get it smoothed out.

 

Yeah, it is when i stab the throttle. The wideband goes to 16.00 and I have to feather the throttle to keep it running until the engine slightly warms up. On idle it works fine.

 

so increase both the throttle pump coolant correction number and the fuel coolant correction bars.

 

does it do this with the engine warm? or cold? if its cold then you should be adjusting the coolant correction map

if its warm you adjust either the main map or the throttle pump (i hardly ever touch the throttle pump map, hint hint) until it RUNS WELL. the wideband will show weird numbers, but its kinda supposed to right there

 

I adjusted the coolant correction map and the throttle pump map and still nothing. Wtf is going on???
