start cut, fuel cut an ign cut at start up.

[Rensjes12]

is it possible of making a map which cuts fuel and ign for the first 5/10 seconds when starting the engine for first time in a while ?

the idea is to build up oil pressure before the engine starts. 

i was think of using the GP rpm limit table. ect and "engine running time" on axis's. then set te rpm limit to 0 .(see picture)

Linkg4+ plug-in (r53 mini+)

r53 turbo conversion.

 

dear regards,

You have the right idea, but engine runtime on the axis is not going to work.  The engine isnt considered running until it is above 400RPM so the engine run time is never going to count up in this case.  You could instead use a general purpose timer that resets based on some other parameters such as RPM above 20 or similar.  

Personally I think it would be better to fit an oil pressure sensor and base the limit on actual oil pressure - then you can also use the same table for safety at high RPM where oil pressure is far more important.

Oke , then i will use the oil sensor. A 2D table would be enough then right ? 

Thanks AdamW

Yes you could probably just use 2D, you might need a second axis if for instance idle oil pressure drops low when the oil is hot.

But something like below would be a starting point, engine wont fire until there is at least 10psi.
