    Need help in logging

    Do you have a wideband feeding into that ecu or is that Lambda reading a default?

    Coil on Plug Conversion

    Thanks Guys, Yeah v5-6 wrx as per my profile there. Serial number 26067. Ignition 5 and 6 are listed in the Aux outputs

    Coil on Plug Conversion

    To do a COP conversion on a '99 wrx do I use the Aux Output Ignition Drives? 1&2 are currently ignition. 3&4 are engine fans. Would I change 3&4 to ignition drives and reallocate the fans to 5&6 and would the fans then work? Can I then change from wasted to direct spark? Where would the signals to the coils be wired to?

    Warm Start Struggles

    Some people have had success changing the injection angle for cranking to earlier in the cycle for E85 so that it is in suspension rather than hitting the back of the valve.

    Knock Control G4+

    I logged to the ecu at 100Hz and yes there were some spikes over the 500 threshold. However there were still some instances where timing was pulled below the set threshold. I'm going to update the firmware as suggested this week.

    That would be awesome Steve. My problem is at the moment is I can't get a known safe run with these little spikes of timing coming out. I pulled the plugs on the weekend and no signs of any det. I didn't get a chance to get the car out but I'll log it to the ecu and report back as soon as I can.

    Thanks Adam. Last time I updated the firmware I had some issues with the tune so I went back to this version. Will the compare function show me what changes. Eg - The TPS needed to be reset.

    Knock Control G4+

    Not yet Adam. Probably tomorrow. We did a lot of logging last weekend with some ears on it with nothing audible. It seems to be happening so quickly I can't even hear it, maybe why the logging isn't picking it up. When it did knock on a separate occasion, I was able to hear a crack even as the system took over and pulled timing. I'm going to pull the spark plugs today and have a look at them. And I'll get some logging done at 100Hz to the ecu and see what that says and report back. How do I look open log files out of the ecu?

    Knock Control G4+

    I'm no expert on how the ecu, knock sensor is interfaced/works mate but if it's not putting out a voltage how would I be able to log it as I have?

    Thanks Timmy, I'll try logging to the ecu at 100 Hz. I had the car on the road with a driver today, I turned the ign trim back to 0.5Deg with some det cans on it. It was still pulling small amounts of timing without anything audible. I've been looking at the spots on the I trim tables where it is occurring it's at half of the threshold and no audible knock

    Hi Timmy, It's because with the cyl allocations set up like that the numbers for each pairing are exactly the same when I log them. Rgds Rob W

    6kHz. It shouldn't be I pulled 3deg out of the positive kPa MAP across the board to set it all up. I've got a driver today so I'll turn the whole thing off and have a better listen to it and report back.

    Hi Timmy, I have the cylinder allocations set up 1,2 and 3,4. Do I actually need to turn cyl 2 and 4 off? I won't let me post log files only screen shots.

    Knock Control G4+

    Thanks for the replies. Thanks Adam, that clarifies the allocations and gains. I am logging "I Trim cyl1 &3". The threshold setting is at a flat 500 for getting the gains and noise profile set up. I have had ears on it but haven't turned the Ignition Retard limit back to zero as I wanted to see what it is doing. Just trying to get my head around why the I trim is showing retard below the threshold. I'll attach a log screenshot and set up shot below.

    I have an Ej 25 with forged pistons etc. Setting up the knock control with the suggested frequency at 6kHz. It has been set up to allow the ecu to pull 3 degrees timing out. The thresholds have been set at 500 for setting up purpose. It is my understanding that once you have the engines noise profile on a clean run you set the thresholds 20% above for the load rpm ranges but it should not be pulling timing until the threshold is reached. For some reason it is pulling between 1-2.5 degrees out at random times at half of the threshold levels. Is it hearing knock below the threshold and pulling it out or should it not be doing that? Also the cylinders are paired for wasted spark 1,2 and 3,4. The way the knock sensor is positioned on the Ej is difficult in regard to setting the gains to get them even as it is closer to 2 and 4 than 1 and 3 which gives odd distances for the cyl gain settings to even them out. Is there a trick to setting these where you do each cyl individually or turn one or two of them off ?
