VersaTune User Forum

Hi folks,

User from New Zealand here. I've been emailing Steve about getting this software working for my Japanese imported Mazdaspeed Axela. I have it installed and have loaded the base tune for 93US/98EU Octane.

Using the dashboard I've run into an error though. I've been trying to get the Air Fuel Ratio or lambda values I get this:

"Negative response ID 31 received when using service 22."

I've attached a screenshot.

Please try removing parameters from the dashboard one by one to figure out which one is not supported. Try logging after you remove each one. Let me know which one is the culprit.

in that list, it is definitely the Actual Air Fuel Ratio. The others will work fine.

You are correct. The AFR PID is not implemented in the stock code. How bizarre. I'll see if I can add it.
