The Nefmoto community tune project is proceeding forward once again. Here is how it stands compared to a couple “off the shelf” tunes. The Nef tuning efforts are currently being directed at the initial boost onset to see about getting some more pressure as the actual pressure is falling short of desired.
When that is completed it will be interesting to see if the low end acceleration gap is closed. At the top end the GIAC tune pushes a few more psi than this tune presently does so the Nef tune may never close the gap up there depending on how we handle the upper rpm boost level.
I’m resuming the process of developing a modest Stage 2 tune and at the same time recording other data. I remain impressed by how well the stock intercoolers work with the K03’s.
Below is a chart showing a series of three WOT pulls with boost climbing to 17 psi and then tapering down to between 10-11 psi. The orange and blue lines are the temperature of the air exiting the compressor, pre-intercooler, and just past the throttle body, post-intercooler. The stock IC’s do a good job holding these temperatures in check, even over a series of three pulls.
