It has a stock 1bar with MAF patch. I can log the MAF HZ past 12200 fine but car goes lean after it goes past the last cell in the MAF table which is maxed out at 67.725(or 511.99 g/sec).
Other than upgrading to a 2.5Bar or tweaking the PE table, is there a way to add fuel back to the areas above 12,200?
Thx

You need to scale.
It's already applied. Read the first sentence of my post.Quote:

As 12,200 is set to 512 then you need to scale more to give you room to roll back over to the 1000 hz cell. As a cluge...set 1000 hz to a value larger than 12,200 and work PE. I believe once you go past 12,200 it reverts back to 1000. Will never hit that cell in the real "driveability" world
Not the best but should work. Other option is to tune in SD....raping PE is not my normal course of action :-)

Update....I believe the 06 didn't have the "revert to" issue, only the 2005 and the MAF Patch should fix it......So going lean is just because you are running out of resolution....need to scale more or go with SD.
Not in the E40. Do the car in SD and scale it.Quote:

Your airflow is flat lined at 23.83? What does you cell have in it at the hz it flat lines?Quote:

Just a reminder, until we see the tune file, don't forget to scale the timing as well. G/Cyl gets factored and the timing table offset accordingly.

Here is my scaled tune.
Car is running MAF only.
Looks like 35 tables scaled. Didn't touch the transmission yet. Did I miss anything or are there any tables I should have left unscaled? Idle stuff?
Cylinder Charge Temp (Bias and Filter) s/b offset (like timing table) instead of factoring the contents. Injector Flow rate is fixed across the Manifold Vacumn, s/b linear ramp like stock but scaled by 50% unless you have a Vacumn Referenced Fuel system, Mode vs Airflow s/b offset, not contents scaled, Warmup transient Decay max and min s/b put back to stock, no scaling required, Impact Factor Gain s/b offset, not contents scaled.Quote:

Don't forget the tranny Torque...scaling will be offset not contents scaling.

10-4. I will go back and offset vs scale those tables.Quote:

For comparison. Still need to scale tranny and run VE through Bluecat tool.
You can use the current injector data if the other tables like MAF and Timing were tuned accordingly as long as all tables are factored at the same percentage, including the IFR. It's just not the best way to tune as you are starting from erroneous injetor data and now you need to fudge the numbers as you go. I personally don't tune that way but depends on your preference.
If you decide to go this way, you will have to find the flow rate of the injectors. I am pretty sure that his kits come with either 52 or 60 lb injectors. Believe the LS2 kits come with 52 lb'rs (unless you bought other options or again, have the vacumn regulated fuel regulator) and if rated at 58 PSI then the IFR would start at 52 and run up to 56.96 or so. You can interpolate between the two ends to fill in the rest of the table. Then scale those values by your 50%.
Maybe someone else can chime in on the injector flow data data.
