have read these have an overboost controller mounted somewhere near drivers shock tower.
not sure what it looks like, where it is , what connects to it or how it controls
did all 3 plug and 4 plug ECU L Turbos have these overboost controllers??
I have a 3 plug flapper style.
i do have a pair of what look like vacuum switches bracketed onto front of RHS shock tower each with two wires connected ??

That is them. One if for the boost map and turbo light on the dash. The other the the overboost thingy.

Yeah on flapper maf (85-86) turbos, there are 2 boost switches, one for the boost light, the other for the ECU.
But hotwire maf (87-94 models) only had one boost switch, for the boost light.
The some hotwire models also had a WGDS mounted on the drivers side strut tower, (wastegate duty sloenoid) connected between the turbo and the wastegate. I cant find a detailed description of what exactly it does, but i have read somewhere that it is a altitude compensator, upps the boost at lower atmospheric air density, or something like that. When i get mine going, i will do some testing to find out exactly

Is that what this disconnected solenoid is on my RX?

aha, thanks guys. So if a boost controller goes in, one of these babys needs to be pensioned off !!
also seen this solenoid of rOOfi's on another car and thought it replaced the twins, but it was a carby version , so curiosity solved.
