Not sure if it will help with lean tip in everywhere, but it will mostly fix the lean spot between 2000-2600 rpm.

For the USDM Evo 9, the requested linear FPW is at FFFF6C30/31. This variable corresponds to the values in the input axis (aka x-axis) of the PW linearization table. Its a 2-byte value. I assume you'll know where to find it in the ROM you are tweaking. You'll need to pick a spot in the MUT table to log it. I log it at MUT 2B/2C. My EvoScan definition is:

<DataListItem DataLog="Y" Color="" Display="2-Byte Sync FPW" LogReference="2BSyncFPW" RequestID="2B" RequestID2="2C" Eval="0.008*x" Unit="ms" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="0" GaugeMax="66" ChartMin="0" ChartMax="66" ScalingFactor="1" Notes="" Priority="1" Visible="False" />
Ah! I thought it is already built in the rom, but I guess I have to assign the MUT address!

I just logged this item and it gives me 18ms when cold to 14ms when warmed up, is there any chance just scaling might be different?

Current MUT table shows: 993A 993B @ 2B / 2C

where 2 byte injector pulse width logging is 9938 9939 @ 29 / 2A

Well it fixed my lean spot between 2000-2600 with the radium rail/damper but I still have a lean tip in from a full stop. I can fix that by making the car go open loop but is it possible to fix in closed loop?

Gotta fix that with tuning.

An update on my setup, I finally settled on a Boomba fuel rail that accepted the stock Evo9 end fittings.
This has a 1/8 female NPT port for whatever you need to add.
So I got the new trick Radium pressure damper with manifold reference.
This has a 3/8 male NPT port and I was unable to source an adapter in Oz to marry the damper to the rail.
However, Mettle Air in Niagara Falls have a suitable brass adapter 120-CA, and the whole setup works fine and no leaks.

That Boomba rail looks pretty nice, I thought you had Radium rail though, which had the right sized port for the FPD.

Wonder if if you could get a local company to do a small batch of 1/8 to 3/8 adapters in Al.

The Boomba rail did in the end work out ok for me, but looking at the revised Radium rail/damper and fittings setup, that is in my opinion the best setup for the Evo 56789.
