Hey all, I have an AEM Series 1 (I know, it's very old), and have been doing some logging trying to understand how all the trims are behaving. The behavior/function of a number of the logged params coming out of this thing are not very clear.

First off: did AEM ever supply a PDF describing each possible logged parameter's function / role? I cant find one, it's not in AEMPro (the help articles dont come up), and AEM was like 'sorry, not supported anymore'.

If not, I'm specifically looking to understand:

Fuel Map [what is this? larger than expected at all times. allegedly in microseconds]
Fuel (Fmod) [Seems like pre-trim fuel? how does it relate to Mod below]
Fuel (Mod) [^??]
Fuel Pulse [is this before or after trims? after some trims? Often not the same as inj #1 pulse]
Fuel Inj #01 Pulse [I assume this is final pulse width]

These `Fuel Trim (*)` params all seem like maybe fuel map pulse width + their trim. Correct? When no corrections, they are all about the same. Say at idle, each would be around 1k

Fuel Trim (Ait) [non-0 even when no trim]
Fuel Trim (ALT) [non-0 even when no trim; table all 0s]
Fuel Trim (Baro) [non-0 even when no trim; table all 0s]
Fuel Trim (Start)[non-0 even when no trim]
Fuel Trim (TPS) [non-0 even when no trim; table all 0s]
Fuel Trim (Warm-up) [non-0 even when no trim]

e.g. here's data from a couple log lines

Idle where the fuel table's interpolated value should be around 1.045ms. It's usually all good when there are 0 trims

Fuel Map: 5085 (I mean WTF is this?)
Fuel (Fmod): 1045
Fuel (Mod): 1040
Fuel Pulse: 1040
Fuel Inj #01 Pulse: 1570
Fuel Trim (Accel): 0
Fuel Trim (Ait): 1045 (Should be no correction at current temp)
Fuel Trim (batt): 540

Cruising at 2800rpm, trigger tip in trim:

Fuel Map: 5760
Fuel (Fmod): 2340 (Close to fuel table value, okay)
Fuel (Mod): 2350
Fuel Pulse: 2970
Fuel Inj #01 Pulse: 3475
Fuel Trim (Accel): 1500
Fuel Trim (Ait): 2330 (Should be no correction at current temp)
Fuel Trim (batt): 540

One where the Fmod and Mod dont match

Fuel Map: 5625
Fuel (Fmod): 1145
Fuel (Mod): 680
Fuel Pulse: 640
Fuel Inj #01 Pulse: 1190
Fuel Trim (Accel): 330
Fuel Trim (Ait): 1145 (Should be no correction at current temp)
Fuel Trim (batt): 540

Thanks for any help!
