Hello evryone...

Am just new here on this forum so please bear with me with some of my queries...

Am using an S300 engine management for my jdm itr turbo...

I was able to tune the car at idle speed after the engine has warmed up with optimal fuel mixture of 14sh...

But the problem is when the engine is cold it tends to go very rich indeed around 8 or 9sh on the A/F ratio on the wide band innovate LC-1 Db gauge.

I wonder how can i able to sort this problem out..

Please I needed your highly solicited technical advice on this..

Thank you in advance...

You may need to make adjustments to the Fuel Compensation section of parameters.

Thank you spunkster....

But the thing is, I dont know what changes to do on those figures. How would you edit the figures there? I mean for the water and air temperature (low load; medium; high)

Would you increase the figures of the correction % or should you lower them to compensate for the cold start?

Am really lost...

Please help thank you very much....

If you are running rich you remove fuel, if you are running lean, you add fuel. If you are still unsure of what you need to do I would suggest taking the car to someone familiar with tuning so you don't damage your engine.

I've got the same issue, summer time the car starts at the 3rd try, it's winter now and the wideband reads lean the whole time of cranking.
At what column and row is the ignition trying to start the car? From here I can add the fuel to get it to start the first try? Just need some PROFESSIONAL advise SPunk. H22A into a EG with a 110 oct fuel with a GM 3 bar map
It's been dyno tuned for the GM under a MoteC got 394hp and 294ft.lbs of torque
But how do you compensate for the outside air temps?

You can adjust the fuel compensation tables. No wideband will read correctly when cranking.
