Bit of a long shot here. But does anyone here have a copy of there ecu map on the computer? For an Omex preferably, but dta etc will do.

Could anyone that has, put up a screen shot of there coolant fuel trim table please. The table showing the extra fuel added by the water temp.

Just wanted to compare it to mine, as I need to trim some of the fuel out as it's over fuelling when cold.

I know it's all dependant on engine etc, but I just want something to compare to that's all.

Cheers.

That's what I'm doing. Got the wide band in and ready for starting it up for the first time in ages. It runs fine when warm just rich when cold.

I was just wanting to see if there was a rough curve to the coolant fuel graph that is the common shape. So I know if I'm heading for something vaguely normal!

It's not - water temp compensation tables are normally done on a percentage basis from the base fuel map.

That would be grand if you could rich.

I know it's a percentage of extra fuel. As you say, must be a percentage of the map value added in.

As said previously, I know it will mean checking the wideband but it's just to get a rough idea of the curve shape that's common. I think currently my map at initial starting water temp is adding 50% or more fuel.
