Thanks, all
We’ve spent a lot of time troubleshooting today but have the car running really well, have verified VANOS is working, and have just strapped it to the dyno. We’re going to do a base / drivability tune - I’ve got lots of work left to do - but bottom line is that the electronics are functional, we’ve got them behaving well, and the car is happy. I’ll shoot some dyno video and post later but I am currently really happy. The folks at Lowe Group Racing are fantastic and have been extremely patient with me, which is nice.
