Which fuel map takes presidence?
I have a E6X and since I've last ran my 13bre I've changed the primary injectors from 550's to ID1000's. The base map I'm using is for 850 I think for the primaries and has settings for multiple correction maps such as coolant temp, air temp and so on. My question is for zero throttle fuel settings which map should I be making corrections on? Which fuel map being either a base map, or a correction map has priority? I'm attempting to start with the coolant temp map since I assume based off a cold start attempt it should take a priority.
Thanks,
Matt

Both...
When the engine is at full operating temp, you only want the base map used. That's your standard RPM based maps through the range. Anything below that you add fuel on the coolant map. The coolant map is the percentage add to fuel to the basemap. Both need to be "right". Also, since you changed the primaries, you need to adjust the base map to compensate.

assuming your 850cc base map is decent, use the percent change function and -15% fuel (below staging) from both base fuel and priming maps. correction maps dont change. i would start on your last working 550 map though (and use -45%), not a base map. ive never seen a decent base map posted on these forums

Per the haltech manual in no exact terms "the main fuel map should be good before you go dicking around in the enrichment maps"
i have followed this rule pretty well. if the car is warm and idles at various rpms at various loads relatively well, then i start with the coolent and water temp maps.

The air temp map will be based on gas law. It's generally not something you tune. This map needs to be setup before you begin working on the main fuel map.
The coolant temp map should be zeroed out at operating temp, say 150*+. Add just enough fuel at lower temps to allow the engine to run cleanly after you have a good working main fuel map.
Throttle pump will be the last fuel map to work on.

When referring to "below staging", do you mean the first staging map specific to the primary injectors? Meaning do I only make the %correction to the first stage(primary injectors)?
