Memory dump of ECU

[longassname]

I believe you only had 2 or 3 parameters wrong when you posted them way back when.

If I may suggest--what you should be working on is identifying the routine that calculates the learned ignition advance correction and where it stores the learned values. This feature of the SVX ECU makes it unecessary to have fancy memory devices which can be rewritten while the vehicle is running in order to do auto tuning. All you have to do is let the ecu do the auto tuning and then pull the learned values to use to correct your ignition advance tables. This is 99.9% of the tuning that is within the abilities of 99.9% of end users.

Even for OBD1, it would be a huge step forward to know that we are using the right parameters for the data logging.

Thanks for the input Michael.

I see what you mean about letting the ECU do the tuning itself. Ingenious. I would never have thought of that. I will spend some time looking in to it.
