I think the tables your refering to are the port to direct injection ratio tables.


There are three cold warm and hot. Its best to keep same values in all 3 tables


The value in the table is the amount of port injection sometimes its a value between 0 and 1 and sometimes it might be a percent depending on which definitions your using.


so if tavle has 0.3 or 30% it means at that load rpm point ecu will use 30% port and 70% direct injection


Best nevercto put 1 or 100% in the tables as that means all port injection. This means no fuel through the direct injectprs which are in combustion chamber of engine. That would likely cause direct injectors seals to overheat and get damaged. You probably want not to go over say 0.7 to 0.8 or 70 to 80 % port injection so your always runnog a good amount of fuel through the direct injectprs

My man..
Yeah it confirmed.. i just tried today on street
It was very torque full
I feel the pedal react to car move forward is better with pi table from the rom raider stage 1.
I think all the same through all stage rite
Even i have see the base ecutek map which is pretty the same .
If not mistaken the value is 0.3 in low and 0.2 at the max
The off in the middle of rpm
And back on 5000 rpm up.
Maybe you can share a stock ecutek table map

And i think there is treshold of they switching. By temp or something else. I forgot.

Well basically to translate from flash rom language to motec are really challenging.
But i am not giving up as i can feel better and better in everything i do into the engine.
