rich on cold start up
rich on cold start up
car running 8:1a/f-11:1a/f on cold start up how can i fix this with the s300?
and could this be the cause of the mtor dying if i dont step on the gas pedal????????

Re: rich on cold start up
In the parameters theres a tab called, fuel compensation.laziebun wrote:car running 8:1a/f-11:1a/f on cold start up how can i fix this with the s300?
In there you want to lower the correction % in the cold low engine load for the said temps where its causing problems.
What wideband are you running?

Is the wideband warming up?laziebun wrote:im using LC-1 but i cant seem to get the volatge offset right so i just monitor it logworks..
is this what your talking about (picture below)
It sometimes (if your using a DB gauge) gives readings like you explain as the sensor warms.
And no, its the water temp correction you need to change, the numbers that are 70.3% 70.3 47.7 34.4 and 18.8.
Depending on your temp depends what u need to change.
Say if its somewhere between 32 and 67 lower the 34.4 down a bit and the 18.8.
Probably more the 32 degree cell than the 67.
But by the looks of things your going to need to take a lot of fuel out. Maybe around 10-20% to get it nearer a 12 or something. keep an eye on your water temps and see when its starts running more normal.

im using my laptop and the wideband is warming up.
so my question is why dont i make changes to the air temp idle and light engine load??? since i am trying to get it to start and stay running at idle.
But ill try what you suggested and see how that goes.
im going to wait till the enigne is complete cold and datalog a cold start and post it here see what you think, do you have logworks????

When the engine is cold, it runs on the water temp correction, the air temps do effect it, but this is for when the air intake temps are warmer and colder.laziebun wrote:im using my laptop and the wideband is warming up.

If your engine run's fine when its warmed up, the air intake temp should still be very similar its just the water temp what would change.
Yes i have log works.
Try making the changes and see if it gets better.

well its supose to be a map that was tune for my setup, but its acually a map from hondata calibration forum. How do i know this? i downloaded a b18c map with a revhard set up and it pretty much mirrors my calibration. So now im trying to learn this tuning thing myself with forums help and a few books.

unfortunately, your car is your test car.Keep reading, just as i did, and you will understand. Running that rich at idle is just outright rediculous!laziebun wrote:well its supose to be a map that was tune for my setup, but its acually a map from hondata calibration forum.
