I need the following code for the 96260009/96260709 xml. The code below is what I have now and it's wrong. Hoping someone has the correct code and can help me out!

<table name="Lean Spool Load Threshold" category="Fuel Lean Spool" address="39a2" type="2D" level="1" scaling="Load8">
<table name="input value" address="63da" type="X Axis" elements="14" scaling="RPM"/>
</table>

<table name="Lean Spool Trailing Time (Rich Side)" category="Fuel Lean Spool" address="397a" type="2D" level="1" scaling="uint8">
<table name="input value" address="63da" type="X Axis" elements="14" scaling="RPM"/>
</table>

<table name="Lean Spool Trailing Time (Lean Side)" category="Fuel Lean Spool" address="398e" type="2D" level="1" scaling="uint8">
<table name="input value" address="63da" type="X Axis" elements="14" scaling="RPM"/>
</table>

Are you going to be tuning lean spool? Just curious.

Thanks for that, it was odd I found some slightly different addresses in an old evo7base xml that I thought I'd tried and werent correct. Seems to give the same values as yours though but have thrown yours in.

Got any tips for scaling? Unint8 is the only one that seems to make sense, but Ive seen others in time(s) which would be a lot easier to tune with and make sense of.

I like the idea of lean spool, and from minimal testing I like what it seems to do. First few runs through the gears it activates and leans out during spool time decaying back towards high oct. map values, but after some persistence it has less and less effect, so to me it appears to make short bursts spool faster but due to the need for thermal management it only remains active for a set period. Ive tuned without it so far, but I'd like to experiment with it and if I can make it work for me sure, I'll use it.

The units are roughly seconds according to Merlin's EcuFlash guide (see page 103).

I think I'll re-enable lean spool some day, but I swear that my car leaned out more when I went from 93660005 to 96260709, even with the same fuel and timing maps. So I'll just get things under control first.

Right ok. I opened it to check but didnt re-read it again. Cheers

Did base hi oct. map settings when set the same on both roms result in different actual AFR's? Have seen some differences between default values in AFR mapping table for lean spool which would obviously affect a change in actual AFR's when active, I modified mine to make it less lean under load but when enabled I think you need to also enrichen the base fuel map a little so it doesn't lean it out too far. Or just alter the AFR mapping table to give you desired albeit slightly leaner AFR when LS is active. I'd like to know what a stock evo with LS enabled actual AFR's are.
