ERROR1 and ERROR2
Moderators:R!C0, JonMan, RickS
Hi, I have a subaru plug n play ECU ver 2.59.
I did a log and found the codes for ERROR1 to be 128 most of the time, and 130 sometimes.
I also found ERROR2 to be either 0 or 4.
I tried to search for the meaning of these numbers, but have not found any. But since it is called ERROR, I am very curious about the meaning of this? Is this something wrong with my engine or some of its sensors?
(Please forgive me for beeing such a rookie in this area).

Re: ERROR1 and ERROR2
Maybe someone knows where I can look up this kind of information?
I have looked through the GWv3 help-file, but it did not contain anything about error-codes.
I guess 128 is actually a bitpattern (in binary it is 10000000) and probably means something. I have a theory that the it might be trying to read some adjustable cam timings, and I dont have AVCS. But thats just a wild guess so far...

Hi,
I have attached a manual which covers your version. Yes they are bit patterns, the explanation of what all the bits mean is on on page 32.
Hope this helps.

Re: ERROR1 and ERROR2
Thank you! That did help me a lot 
Map presssure sensor seems to have a fault and there is no signal from the knock sensor.

Hi,
In most calibrations the knock sensor is disabled so not really a problem. For the map sensor, have a look at the parameter map raw, with the engine stopped this should be around 80 for barometric pressure. If this is not the case then most likely the sensor or wiring to the sensor is faulty. If you do have a correct value then check the options map min and map max. The options section of the manual suggests values for these options.

To follow this up, so others can read about it.
My problem was in fact the MAP min setting. The previos owner had it set a little higher than the actual map min, just to trick the engine to calculate "Map as load" to 130 every time I got off the throttle in high rpm. This was done to make the exhaust pop like in an anit-lag-system.
I just had the map min set a bit lower, and problem fixed
Thanks for the help!
