Lean Spool with ECUflash 1.40
Did any of the lean spool fixes make it into ECUflash 1.40?
I'm getting ready to swap from a Evo 8 -008 ROM to a -015, and add lean spool disable. So far I've been able to do all the patches for 2 byte load, Tephra mods, etc but Lean Spool is still unclear for me. I totally understand what it does and how to tune around after the change - it's the implementation and method that is confusing me. I've searched and read all the lean spool threads as well. I've looked at a ROM and xml with the lean-spool disabled and here are my questions.
- Under the fuel tab on ECUflash there is "Boost Enhancement (Anti-lag) Table". It's a 2x7 map, does it have anything to do with lean-spool?
- Under the fuel tab on ECUflash there is "Boost Enhancement Enrich/Enlean (Anti-lag) Map". It's a 19x20 map with AFR values, does it have anything to do with lean-spool? What does this do? I believe this is an added map for lean-spool?
- Under the Turbo tab on ECUflash there is "Boost Enhancement (Anti-lag) stop/start RPM". These are the values you adjust to disable lean spool? In ECUflash 1.40 they are RPM values.
So basically did ECUflash 1.40 fix any of the bad addresses from older versions? And what does that large AFR map do.
Latestly what is the best way to implement this on a 94170008/015 ROM.

The 94170015 xml in ECUflash V1.40 seemed to have several errors. I wish I could remember where I found this to give credit where credit is do, but here is a great xml setup. Who ever did it did a great job organizing it. It's also setup so all the tables are defined in the evo7base.xml and the 94170015.xmp only has address information.
It is setup to use Tephra 5.10, direct boost, and JDM MAP sensor. I changed it to the short version of the MUT table and added the blobbits for the ECU Periphery settings. I believe it is fine to use this xml even if your ROM is not setup for any of these mods?
From another thread on here, it seems like the "Boost Enhancement Enrich/Enlean (Anti-lag) Map" os actually an EGR related map that is used under cruise conditions.

iirc the Boost enhancement table in AFR is labled wrong & is actually a timing map for coolant temp.....I can't remember which thread I read that in.
The boost enhancment start @ 1680 & boost enhancement stop @ 1684 are the Lean spool tables.....set them the same at a low RPM, say 1200. You can also do it with blobbits in fba
