IGN issue

Hi,

It seems that sometimes the IGN value does match with the IGN value that is in the calibration file (see picture).
Any idea on what is causing this?

KManager version: 1.3.5.4
ECU: PRA
vehicle: European Civic Type R 2002
Spark plugs: NGK BKR8EIX
Ground location: as suggested by Hondata

Try clearing security (online, tools, clear security) and then closing the program, then reopen it and load your calibration and upload it to the ecu.

I did it, but this didn't solve the problem. Any other ideas?
Thanks

It seems that the IGN value fluctuates more when TPS goes to zero.

Does it happen also with other ECUs like PRB, PRC?

Hondata, can you please tell me if this is something to worry about?

Thanks

At idle the ignition will be anywhere from 0 to 20 degrees.

We're in the process of testing this in a vehicle.

i think i got some IGN issues as well

why would the ign retard (spikes) at no change of any parameter?

any idea causing this spikes?

We tried the same calibration in a vehicle here, but did not see the ignition spike.
We know that a bad TPS signal causes a similar problem - the ECU thinks that there is tip in retard the whole time. I also suspect that incorrect gear ratios make the ECU think you are changing gear when you are not.
