[s-cars] code 2224 (Over boost condition)

[Jack Gagnon]

Well I looked at the turbo/EM clearance today and it is a bit tight.  About
1/2 inch or so at the closest point.  Maybe I should put the heat shield
back on the cold side housing that the PO had installed.  I took it off a
few months ago to see what housing the turbo really was since I had never
really seen it.

Welcome to the world of overboost. In layman's terms you're running into the
ECU's protective element that shuts things down to limp mode as you approach
some predetermined level of flow through the MAF. There is software
available
that desensitizes this protection but its very hard to come by. Igor and I
believed at one time that this limp mode shut down was attributed to
electronic boost controllers. What was really happening was that the
controllers were actually allowing us to reach these higher levels of MAF
flow. A boost controller could allow you to throttle back on your turbo's
flow negating this problem. As you look down on your turbo what is the
clearance between the compressor section and your exhaust manifold?
