Hello everyone,

I’ve been searching for the WOT (Wide Open Throttle) enrichment table in my tune for a while now, but I can’t seem to locate it as a standalone “WOT Enrichment” table—at least not exactly 1-to-1 as I expected.

What I’ve found instead are related tables like “Fuel Injection – Open Loop Enrichment.” I suspect this might be the main table controlling fuel enrichment at high load, but I want to be sure before making changes.

My goal:
I’d like to temporarily disable or zero out the fuel enrichment at WOT so I can log and analyze my short-term fuel trims without enrichment masking the baseline fueling behavior.

My request:
Could someone familiar with this tuning platform help me confirm which table(s) I should modify? I want to avoid randomly editing tables and “stumbling in the dark,” as I’d prefer to work efficiently and safely.

Any guidance on table naming conventions, axis ranges (RPM vs. load), or whether I should also look for a “Power Enrichment” or “High Load Enrichment” table would be greatly appreciated.

Thanks in advance for your help!

Let me know if you'd like to add details about your specific tuning software or vehicle platform.

might help if you attach your tune to the post (either zip it up and attach it or stick it in a google drive/dropbox and share the link)

My personal map isn't really useful anyway, since basically everyone here has "the same one".
I’d just like to know exactly which table is responsible for WoT.
Vanos is clear, and WoT detection can only be found once in our defined tables, I think.
Sure, directly above it there’s something about enrichment, but not literally “WoT enrichment”.
I just want to be 100% sure that I’ve deactivated the correct map.
Since I’ve installed performance camshafts, an M50 intake manifold, and an equal-length exhaust manifold, I’ve reworked the entire map.
So far, everything works pretty well.
Still, I’d like to know afterwards whether I deactivated the right tables.

Will nobody help me with this small thing?

for WOT enrichment look under fuel directory > fuel injection - open loop enrichment, this is a percentage added to your base fuel table.
another this to look for is under fuel directory > detection - open loop enrichment, this table sets at with TPS percent open loop is activated, on ms41.3 it's activated by load, not TPS %.

quick FYI, your base map should always aim for stoic +-(14.7 for gasoline), open loop enrichment will enrich the fuel by some percentage set in the 2D table per RPM row.
it is best to user open loop enrichment so engine feels smooth in transitions, instead of adding the percent values to your base map which will ruin your cruise and idle.

hope this helps.
