I am about to do the tertiary piping on my corolla and was not 100% sure on the correct mode for the vacuum pipework and the CCV system, hence I've drawn a diagram. Does anyone have any thoughts on it??
I'm running a parallel install with my stock Ecu controlling idle, hence my need for the additional intake temperature sensor
I have a Corolla T-Sport pre-facelift and have put Apexi PFC with no problems. However, TRC and VSC do not work and have no temperature indication on the dashboard. Air condition, power steering, ABS, fuel gauge and odometer function properly from what I know...
the pre facelift was pretty closely related to the celica gts, the post facelift seems to have its electronics a bit more closely integrated. ie my tvss system will not let the power steering function without the stock ecu to give it the go ahead.
Setup looks good, but you will want to move your BOV to the outlet side of the intercooler. You want it as close as possible to the throttle to minimize pressure spikes.
