Unboxing my new Rogue Engineering steering wheel quick release adapter Here it is in all it’s glory. Should make it easier to sit in the driver’s seat with the laptop computer open when tuning the car in my driveway or on the dyno. Will also make it easier to get in/out when I temporarily fit race seats for track days. You can rotate the release paddle to any position you want. The little dimple serves as an index mark, which I located at the 12 o’clock position. This puts the release button, which serves as a safety mechanism to prevent […]
Here is a screenshot of a video I took with the timing light to verify my ignition timing. Initially I set the base timing using the Trigger Wizard per the MS Labs instructions.

The red marks on the timing belt cover are T and 10 (ProTip: paint the lines white or red so they’re easier to see). You can use either the T mark on the timing […]
So I’ve been talking with some other Megasquirt users to request help getting into the ball park with my tune, share ideas and help validate my work so far. omgpham and Valvecovergasket were nice enough to share their tunes with me. And Reverant at MS Labs finally responded to my email with some AFR1, VE1 and Spark1 tables that were scaled for TPS. The maps in his original base tune were scaled for kpa, which is completely meaningless for Alpha-N. But he also admitted he’s never tuned an ITB car before and the tables were just best guesses. I can’t […]
