apu1 vs dynamic efi?

[stew86MCSS396]

I was looking at those after our WB02 conversation, but it looks like 7427 isn't on the list. What a bummer!

Not a total deal breaker, with the 7427 you can add the wbO2 into the datastream while logging.

I opted for the APU1 or burner/datalogging cable, only bc if I was gonna fuel infect 1 vehicle in the stable then I would in turn want to do it to all the vehicles I own including people that locally wanted help doing it.

If it was going to be a 1 and done deal, then I would definitely opt for Dynamic EFI.

If your reasoning to get the APU1 is for emulation and the ability to do on the fly changes well I think it's useless!!! Even sitting in the passenger seat I cannot do the calculations quick enough and navigate to the cell that needs to be tweaked. Maybe someday if we can get AI to make the changes on the fly...now that would be something!!!

Yeah that's the route I'm going, WB02 fed in to the 7427 and an Autoprom. I'm fully expect mine to be a one and done though, that's why the ELB looked enticing. As it is I'm thinking about using my APU1 to get a baseline that will allow me to drive somewhere and have them do the full tune. I don't know if the dozens (realistically hundreds) of hours of learning will be worth one tune, unless I just get really into it for whatever reason.

The AUTOPROM also has 3 analog inputs that can be used for injecting the WBO2 data (and other sensors) into the datastream. Eaglemark made a write up on hw to do this.

Many years ago, I started out thinking one and done with a ‘7427 and Ostrich 2.

Fast forward to now, I would only use the ‘7427 if I needed E-Trans control (4L60E / 4L80E), otherwise I would use Dynamic EFI.

Emulation is great, because you can make changes without having to shut the engine off, and without needing to repeatedly program EEPROMs... It's not about being able to change the cells as they are beng used, it's about the convenience of being able to make changes with the engine running and see the updates in real time.
