Adding ID850's to a Boost Referenced Regulator setup

[Lakegoat]

E40 computer: Does this look correct for the 50% scaled setup? Double stoich, half IFR, half IVT Terms. I will set fuel pressure at 58 psi as shown in the ID website numbers. I can use 43.5 psi and change the IFR numbers if that is a better way to go? I am not sure. I just want to make sure before I crank a new engine in a few weeks. I thought I read somewhere that the offset table would be different on a boost referenced setup but now I cannot find that reference. This offset table is directly from the ID website.

Thanks!

Leave at 58 psi base pressure, offset table should be all 0 kPa column across the board as well as you will always be at a differential pressure across the fuel injector of 58 psi/400 kPa. Rest looks good/

Only concern will be do you exceed the 512 g/sec hard-coded limit on the MAF. If so you may have to revert to SD (could do CLSD if preferred) but there has been discussion on the forum that there is a limit to the VE table as well....which I don't believe has been confirmed and I haven't had time to look into it. Last resort is complet scale with IFR and Airflow/Airflow referenced tables..and Torque tables as well :-(

The limit on the VE table of 4096 would take a SERIOUS engine making some real steam to hit that value.

I agree Dave......I haven't hit that limit yet. though not a lot of samples.
