Is the ECU the same as the one’s in the Celica? I don’t think so, I believe it was remapped by Lotus for their version of it. Anyhow, if it is the same, last I knew you would be better off going with a full standalone because of the ECU’s uncanny ability to learn that something is fucking with it. Piggybacks weren’t the way to go with the Toyota ECU’s in the Celica, you were better off standalone. If the ECU is somewhat the same, or the exact same, then you would be better off shooting it with my Desert Eagle 0.50.
