Self learning Apexi AVC-r

[lukevl]

Trying to tune one on an RB30et now and I have a dilemma. I can't get it to self learn duty cycles to match the target boost levels.

Now I know it won't self learn if 1. Start up duty isn't zero%. 2. If the boost over shoots or is higher than the requested level.

We have an actuator that runs (Spikes) at 1.0 kg/cm2 then settles at 0.90 or so and we are aiming for 1.15 consistantly hence the fitment of the avc-r. Is our target figure too close to the wastegate setting and preventing self learn from working?

Thanks in advance.

You have to have the RPM singal connect for it to self learn otherwise it takes donky's years!

If its spiking in a certain gear pull the start duty down a bit.

You have to turn self-lean mode on aswel. X = Off O = On

Yeah done all that. Set the gear judge and got gear learning all turned on.

2 weird things:

1. When we make the start duty less (more negative) it doesn't necessarily make the spike go away. IN fact sometimes we get the opposite effect. Its almost like trial and error. Does anyone think its because our wastegate setting is too high???

2. When setting the gear judge with the 'capture' feature while driving, the n/s figure climbs the more you rev it. Was the install dodgy? We get good speed and rpm readings. I assume n/s is rpm divided by road speed which would give a constant number (linear gearing) for each gear? Since ours climbs as revs rise in the one gear should we get a better rpm or speed input?
