I haven't recorded any of the 23:1 A/F readings on the LMA-3. I have been working with timing and fuel tables and individual fuel trims on my laptop while watching the LMA-1 A/F hand help unit. ( It looks like someone dump a plate full of spaghetti in my car)

I only have one laptop and it can only read one thing at a time. So I need the Neptune management running so I can make adjustments in RTP.

My PLX A/F gauge will only go as lean as 19:1 A/F, so its useless and reads the word "lean" anything past 19:1. So I then rely on the Innovate wide-band.

As far as power goes its not much. This is done on the freeway at 55mph to 58mph anything faster it needs more fuel and drops to 18.5 A/F. But at 23:1 A/F its enough to keep the car moving at these speeds.

I have access to two dyno's a "Mustang" dyno and a "Dyno" Jet. My first prototype engine made 288whp and 217ft/lbs of torque at 14psi running a A/F ratio of 11.8 on pump fuel.

EDIT I just noticed you want WHP at 23:1 A/F. I don't know what it makes at this level? I would guess 20whp but thats just a guess?
