I finally had the chance to put some local miles on the car while recording data. This was also my first drive with an air filter—until now, I've been running solely with the velocity tubes for about 50 miles. Honestly, I can't say I notice any difference with the filter installed.
For the MAP signal, I routed all six tubes into a single manifold before connecting them to the ECU’s built-in sensor. I ensured all six tubes were the same length, though I have no idea if that actually makes a difference. I might experiment with running on MAP, but so far, TPS has been performing excellently.
Here’s the long-term trim data. I'll incorporate these values into the base VE map before my next drive. I haven’t populated many cells yet, but I’m hoping to get the car on the highway soon.
