So last weekend I installed a Motive Autowerks 3 port EBCS, and I've been over boosting ever since. I've double checked all connections and its hooked up right. 1 to intake, 2 to actuator, 3 to boost. Even with WGDC zeroed out it still hits the fuel cut just over 20psi (boost target) at around 4000 rpm. Am I missing something? I can post a log when I get home if needed. Really not sure on this one what it could be. Bad valve maybe?
edit: Car is a 10' wrx with Nameless catless DP and muffler deletes, Cobb ap, forge splitter valve. No other engine mods and was running fine before the ebcs.

Uh yeah. The part where I said "even with wgdc zeroed out". Cut them by 50% and then kept removing more and more, 10-20% at a time when it still over boosted. When it started getting pretty low I tested it by zeroing out the whole wgdc low and high maps above 2400 rpm, and there was still no change.

A. Hooked up incorrectly B. You zeroed the wrong maps C. The device is defective. You can test the valve by hooking it up to 12v. It should click/actuate. Not much to go wrong with them, its just a coil. |

well there's only 2 (high/low) wgdc maps that aren't compensation maps so I think I got that right. I had been experimenting with my tune previously. I'll take the valve off here in a bit and test it and go from there I guess. Make sure its flowing the right way and all. Thanks for the input!

so I found a cut in the brand new vacuum hose coming from the pressure side of the turbo. The boost pressure wasn't reaching the valve. On another note I tried a few maps I had made along the way, and ended up with the Stage 2 OTS map being the best running one. I really didn't have to anything to it, logs look pretty good.
