AEM Boost Gauge > Serial output

I have an AEM boost gauge. It has serial out.

Is there a way to incorporate the feed into nistunes logs, just like wideband O2's?

May be possible. Just been rewriting the wideband classes this week to simplify adding more units

Can you point me to information about what the output looks like so I can see how it can be read in? Assuming it may be similar to how the UEGO works with just text output?

Yeah, I've only had HyperTerm hooked up with ACC on. So it only read 000. I'll take it for a spin and record the stream.

Not sure why AEM do this but vacuum is 020 (20hg) and positive boost is 020 (20 psi)

The LED reading is the same [ 20] can mean 20hg or 20psi. They should make hg with a -
i.e. [-20] is hg and [ 20] is psi

Anyways HyperTerm output is like so:

Code: Select all

020
020
020
018
018
018
016
016

Code added and tested today. Added a 'boost' item to wideband for AEM

Thanks matt, works pretty much as expected. No idea why AEM don't differentiate between vacuum and boost.

As you can see here in the shift change 26hg is reported as 26psi.

I'm thinking I'll just pick up a DLP IO-8 next week.
Do you know if anyone has a lookup table for the boost gauge? (I'll ask in the DLP section also).

Thanks again.

No I dont. You could contact AEM and see if they have anything?

Yeah I found the info I need. I'll post the tables and cvs files once I make them.
