A little late to the party on this one, but if you ever want to go back to MAF, we have the technology. Hmmm...sounds familiar...how about THE SIX MILLION DOLLAR MAF?
With a new MAF, connector...
Because the MAF signal is being limited by the max airflow vs rpm table which happens to be 23 gm/sec at 400 rpm and below (0 rpm).
Siemens 60s can run acceptably, even in a stock displacement applications (350), but there are a few compromises with running an injector of this size. First step is getting the offset tables right....
Its simply a matter of scaling. Instead of grams/sec, what if we could rescale the airflow and fuel calculation into something else? Maybe kg/hr, lb/hr, kg/min? Hey, how about something like...
Exactly. With appropriate scaling, LV8 can cover the entire possible range of gm/cyl and also serve as at least an indirect indicator of boost. In my case for example, the LV8 is scaled for 150% of...
Fair enough. A light re-tune for the injector swap should be sufficient in this case.
The MAF sensor shown is from Blowerworks (including aluminum housing and meter). The tuning is based upon a...
I agree.
Here's an example implementation.
If you look closely, you can see the MAF just upsteam of the throttle body coupler. In this case its $32B based code running in a 165 ecm with 765...
Long time contributor to both TGO and CF. Nice to find a focused EFI tuning site that covers a wide range of vehicles and systems since there's more to tuning than just thirdgens and C4s.
