Startup Procedure and Autotune

[dsddcd]

So, I am working on my base cal so I can tackle the 9 Hour drive to the tuner, and I have a few questions.

Here is the startup procedure I have used so far with the addition of testing all the electrical and the mechanical including setting the FPR........ But if you have any tips I would appreciate any info you have.

(1) Adjust the
a.) I/J Batt Offset
b.) Change the Coolant temp Calibration
c.) Calibrate all the extra sensors I added/changed

(2) Rescale my break points

(3) Build a base map which has been interpolated from the base map and other fuel and Ignition tables

(4) Set the Throttle Position Min & Max

(5) Checked the Timing and adjusted for 0deg both at low and high RPM to ensure no drift

(6) Adjust the idle

(7) Monitor AFR’s while raising and lowering the RPM w/o load and appleid scalars to the base map


So far the car runs and drives at low load acceptably but not loaded and since I am a one man crew I would like to try and use the Automap for my first ruff in then commandeer someone to drive the car while I street tune the fuel.

Problem is I cannot get the Automap to work, the instructions are vague on the topic so if anyone has experience with it pointers would be great. Here is a how I have set up the Automap function based on the instructions, as I drive it does populate the Log table however I cannot seem to figure out how to get it to make changes to the fuel map with the use of the "Program Changes" feature.

I am also struggling to understand the “Automapping Initialize” parameters.

They never explain what the “Target Accuracy” they explain what is does but do not give a unit reference. So if I have 0.5 in there does that mean that it will only make changes over 0.5 ms to my I/J Pulse Width or does that mean that it will only make changes if the error is more than 0.5% or 50%..............

The same goes for the control logic, based on the equation below what units is “Change”, is that Pulse Width, Percent…..

Change = (Target Value – Log Value) * Error Multiplier + Error Additive

Thank You gain for reading

1. The automap feature in AEMPro is intended to be used on a dyno where it is possible to hold the engine in one load cell for a certain amount of time.

2. Quite a few tuners have reported the automap feature isn't as fast or safe as manually adjusting the fuel map. Don't forget that a misfiring engine will result in inaccurate AFRs. Some sort of update will be included in future versions of the AEMTuner software. Some people prefer to use the closed-loop O2 Feedback and apply the O2#1 FB Value percentage to the fuel map.

I am still struggling to understand the “Automapping Initialize” parameters.

I wish there was more explanation on this too.
