Would like some insight on scaling for ID2000's on E38

So, basically I have a question regarding scaling this E38. Right now it's set up on a custom 2.5bar OS, and has already been scaled by 50% to make ID1000's fit. Now, well that no longer works.

The stoich trick does not work well at all on this setup because airflow data reporting gets thrown way off, so I'm having to do everything manually which is no big deal, but understanding what I need to scale by is the hard part to me.

Using the ID data, I can get a 75% scale to work on the IFR side of things as this 212lb/hr injector becomes ~60 lb/hr @58psi. Does that mean that everything that has already been scaled by 50% needs to be rescaled by another 50%? Or does it only need to go 25% further? (Anotherwords do I multiply the airflow referenced tables by 1.50 or 1.25 to get them to match?) Hopefully you guys can open my eyes on this.

Thanks.

whats your IFR limit in your PCM? 127lb/h?

Negative. 63.5 lb/hr :(

ouch!

did you try the regular scaling of 1000cc and cut your VE by 50%

I'm in this same spot :)

After swapping my 57mm Turbos with 76's, I need to get rid of those 1000's cc and get 2000's cc. I didn't do it yet but it's good to see what I will have to do later, however with an E40...

Hmmm, or a Pro EFI???? :secret:

It's easy if you have a manual transmission and don't have to worry about torque reporting.

I guess my question wasn't all so clear.

Do I need to multiply my already scaled tables by 50%, or 25% in order to get the correct amount of scale which will equal a 75% scaled down tune?

Or as per Stecks logic, a 25% scale.

Multiply it all by 0.5.

Thanks.
