Mapping Apexi Power FC via datalogit...correction map or base fuel map?

When mapping the Apexi Power FC via the datalogit do people adjust the actual base map or do you faf about with the fuel correction map?

 

I currently have all the figures in the fuel correction map set to 0.00 and have been adjusting the fuel map directly. However I read somewhere on the internet (on a celica forum or something) that you should adjust the correction map and not the base map as the ECU uses this to run closed loop correction. I just cant see the point in having a fuel correction map as well as being able to edit the full fuel map.

 

Advice from those in the know please!

I would say you map the main map, correction maps on standalones are usually for nitrous and race fuel etc.

 

This is the confusion though because you only have access to the main base map when using the datalogit or Power excel programs. If you map via the handheld unit (which would be a nightmare) then you only have access to fuel correction map and iginition map...not the base fuel map.

 

My main question is if i leave the correction map @ 0.00 and change the figs in base fuel map, will this effect the closed loop running? What is the norm when mapping the Apexi?

 

Where's Ryan when i need him ;)

cheers ryan, so its a good idea to use the correction then? I am pretty much starting from scratch from the stock apexi basemap so its obviously setup for the stock twins.

 

Dont fancy selling me a base map for a GT4088 on 800cc injectors do you ;) .

Did you buy a new 4088 or did the one you get off Gaz turn out to be ok?

 

I had a brand new precision one. Gaz's is def foobard. Im still of the opinion it had shrapenel through it as i have seen a few that have been run for quite a while without any signs of damage.
