  1. Some strange settings, but fuel seems to be fine. IAT´s are strange unconstant.

    Knock control isn´t setup as it should be! Can´t see, if it was knock related failure. 

    However i think ignition timing is 3-4 degrees off, what i have seen to other high power 3sgte´s.

    Is the ignition timing matched between engine and ecu?

    Could you let us know more about the setup?

    Early Gen3 3sgte tend to blow the cylinder wall with forged internals.

  2. Just some small questions....

    When i use a flexfuel sensor, the ecu would be able to fuel temperature to calculate fuel density. Is it done in the actual firmware?

    Regarding IAT Mode...is the IAT trim table a trim above the ideal gas law? I haven´t found anything in the online help, if you should put in the ideal gas law differences or let it zero for a starting point.

  3. Hey Simon,

    thanks for the reply. I was also thinking that the sensor could be the reason as this is the only part which is different to the other engines before. I am going to try a different one! But i think it is a bit strange that it cuts straight at knock level 400 as i thought the gain is done by internal knock detection.

    I attached the log and the tune with the low gain setting. I stopped the dyno session after that as there were too much other problems with the car.

  4. Hey

     I am currently tuning a MR2 [MR2 V2-3 #TST205 latest firmware] with a 10mm bosch knock sensor.

    I was trying to adjust the gain of the knock channel so that all cylinders are running around max. 4-500 under normal conditions.

    But it seems that all recorded levels above 400 are cut down to 400. Typical max values are 1000!

    Using a very low gain [max levels below 400] i see the typical rising curve of a knock sensor on a normal operating engine.

    I haven´t had this problem on other 3sgte´s with a link g4+ before and can´t find any setting which will cause this problem.
