Testing firmware 1.2.15 Knock

Car: Hyundai 1.6 16v

Wasted spark

60-2 no cam

Knock seams to work nice, I can hear the engine knocking and see the spikes in Vt.

Issue.

1: When loading 1.2.15 I have to reduce req. fuel from 16 to 12 ms

2: Also I have to type in big numbers for Fuel cut and fuel resume (20000 and 19000) this function act like rpm limiter now so something Is wrong her.

3: If playing with knock sensor 1 and 2 it will effect the lambda value somehow. Sensor like 1-1-1-1 is good 1-1-1-2 will make lambda go bad. (nothing connected to knock input 2)

4: Gauge of lambda target is not showing the correct value of the lambda table.

Nice function to have:

Ve live tuning is a cool function and if we could have the same function for knock it would be great.

Tune your car so you believe there in no knocking (low ignition advance) then turn on “knock live tuning” and Vt will store all numbers in the knock table. Then you will have all threshold values stored easily.

Also we could use a “if_knock” Flag/tag and a counter for every cyl.

3 log files to look at.

The car is not tuned well cores of the hack I made to get this firmware to work at all
