Hi there, I just installed the new software, put the correct numbers into the dyno settings and loaded a log. The chart however is not really what it should be. The car made 480 engine HP / 530 engine NM on this boost pressure on the dyno before.
Something I should pay attention to?
Thanks

You add this function in past (I would say becouse of my wish), and now its over -why? :slight_smile:
Some time its handy to have this functionality for example if you have voltahe that decreses when the fisical value is encresing. Than its better readable for human :slight_smile:

5

I would like to ask how the Drivetrain efficency in the updated dyno tool should be determined?
The dyno tool has no help, is there some documentation to be found elsewhere?

6

I had my car on the dyno and it gave a .92 efficiency (NA MX-5 Miata). 4WD should be lower, some other cars might be a bit higher.

You are right. It fixed an issue with the scatter plot.

I will revert this change and fix the scatter plot issue in another way.

11

I’ve tested and it works for me.

You can try to delete the following file:

My Documents\EMU_BLACK_V3\logChannels.xml

12

Try to improve it for the next build

Window opening/closing/order behaviour is well received :call_me_hand: thankyou!

Ur lambda/rpm/map is oscillating….thats why u also see the egt oscillate.

17

hi i have looked at many things and still have a big amount of oscillation . i have long driving log its too big to attach here .

so i have the same issues with v2 firmware and v3

how ever i found a way to stop the oscillation of the egt by disabling the o2s in >oxygen sensor parameters changing it from lsu4.2 to any other thing the egt will read normal .

i also tried to unplug the sensor o2s it still has dose the same oscillation .

so the next question is why is the o2 sensor settings have to do with the cause of oscillation ?

@Jadzwin_ECUMASTER can you please help with an explanation. ( or maybe a bug when using lsu4.2 or lsu 4.9 )

18

I have never seen such behaviour, however we will investigate this.

hi can you tell me a bit about the set up you using ? lambda setup 4.2 or 4.9 ? > egt ? all wired directly to the ecu ? or with can to lambda ? or egt to can ?

many thanks
