FN904A Spark Questions - Solved

Unread postby yeastieBoB » Wed Nov 15, 2017 10:25 pm

Confused about which table to use.

Spark Sea Level – FN904A – DEPRECIATED, located in Spark / Ignition > Console PIDs, has data.
Spark Extended – FN904A, located in Tuning / Engine / Configuration > Spark / Ignition, is all zeros.

I expected the depreciated table to be empty, and the table under Tuning to have data.

The A9L2 Base Calibration page says to “increase the ENTIRE TABLE (ALL CELLS) by the difference of MBT spark at 3k+ subtracted by current value in tune at 80 load and 3000 rpm.” However, I don’t see a row for 80 load in the spark table.

The example calculation uses 28, which is on the 70 load row. Is that the value I should use in my formula?

did you download the latest a9l2?

if the depreciated table has data then that means you dony have the fn071 patch enabled in your tune

It looks like the A9L2 I have is from July 2016.

I tried downloading a newer one, but the link on the A9L2 page just takes me back to the home page. I don't see the A9L2 on the downloads page. Am I missing it?

Thanks, I found it. Sorry, I overlooked it on the base tunes drop down menu.

Last question below.

The A9L2 Base Calibration page says to “increase the ENTIRE TABLE (ALL CELLS) by the difference of MBT spark at 3k+ subtracted by current value in tune at 80 load and 3000 rpm.” However, I don’t see a row for 80 load in the spark table.

The example calculation uses 28, which is on the 70 load row. Is that the value I should use in my formula?
