I told myself I would stop spending money on the Alltrac for a while...
...I'm such a liar.
Today, after fiddling around and scrounging parts from numerous places I put in two cheap little things; a RadioShack FCD, and a HomeDepot boost controller.
The FCD thingy baffled me for a moment as I saw what at first seemed to be the MAP sensor, but the stupid wire colours weren't matching my EWD...until I saw another sensor that looked identicle (3-wire plug, vacuum hose going to the intake plenum) with the right colours. Both are in the same area so I dunno offhand what that other one is supposed to be doing.
I left the MBC at it's lowest setting, but I guess the spring I picked up is a bit stiffer than what's normally used as I saw the telltale boost gauge hit 15PSI and I wasn't even at full throttle! And rather than get the embarassing feel of fuel cut kicking in I backed off from that point. This weekend I'll have to fiddle around with it so it behaves the way I want for now.
Yeah, I know, I'm easily amused from just a small power bump.
