I have just pulled that same ROM ID from a JDM REV D (E-Tune) Let me know your email address and will send you the XML for Romraider/Enginuity

Download Subaru Select Monitor (SSM) protocol. Adjust timing up to +5 or -5 degrees http://developer.berlios.de/projects/freessm/

EcuTek (Flash 99/Subaru K Line 99) can reflash these JECs: Legacy Twin Turbo - ad981 Legacy Twin Turbo - ad981 Legacy Twin Turbo - ad983 Legacy Twin Turbo - ad984 Legacy Twin Turbo - ad985 Legacy Twin Turbo - ag292 Legacy Twin Turbo - ag302 Legacy Twin Turbo - af181 Legacy Twin Turbo - af330 Legacy Twin Turbo - ad971

Due to the more complex nature of the TT boost control (switching between boost control solenoids and the sometimes overlay of control between them). The system needs to be kept intact and then you can try and manipulate around that. Try this: MBC in line to the primary turbo wastegate actuator after the T junction.Therefore adjusting only how much boost/+ve pressure the actuator gets (similar effect to a stronger actuator spring but variable) this should control 2nd boost MBC in line No:5 to the top port of the large ECV actuator.This again will adjust the boost/+ve pressure the actuator gets.This should control single turbo/dual spin up boost See how it goes.

Syms parallel headers: Solenoid Box:BE5 Hose No:1 remove/cap (this will leave IACV open) Hose No:2 remove/cap and cap IC port Hose No:5 remove/cap (ECV actuator removed) Hose No:6 remove/cap (ECV actuator removed) Hose No:8 remove connect hose No:22 from DPS (this will/may stop the DPS CEL) If CEL persist then leave hose No 22 open to air and cap Hose No:8 . Remove Supercharger Pressure Relief Valve - SCPRV (Hose No: 22 is connected here) and plug intake port and cap secondary turbo stack

What TT turbos are you using?

No.

Yes. The unlike the VF14 the VF21 has no wastegate /actuator. The hose that goes to it, just needs to be blocked off.

Internal wastegate only on the VF20 primary turbo.

The matched pair of VF20 primary with a VF21 secondary

The bolt pattern for the uppipe to the secondary turbo exhaust housing is different.Due to the presence of the ECV.

The only available off the shelf upgrade is a:PE1016F turbo

You may be experiencing Drop In. The TT has what I call two distinct VODs 1. Transition: This is the one noted on the Dynographs as the RPMs climb to max (same gear). Usually with a noted boost drop of approx 8 psi @ 4100-4200 (BE5 Rev E) This void is usually not "FELT" as much especially post tune. To improve this and get to boost drop to approx 2 psi. The AICV can been replaced with a passive one way valve and the SPRV removed. Therefore no dumping to the intake.This is similar to that used in the Toyota Seq TT System 2.Drop In: This is where th ECV (4100-4200 rpm) has just opened and then you up shift ie 1st --> 2nd before the secondary turbo has fully boosted.RPM then drops to ie 3500. However the ECV will not close until 3300 RPM (return point BE5 Rev E). Essentially in twin turbo mode in low rpm and trying to boost. To improve/remove this move the transition RPM points ie ECV open @4600rpm and the return/close @ 3900-4000 rpm. this can be done via ECU reflash if you have DENSO ECU or via Zerosports Sequential controller for the earlier TTs

YES. ->Put in a Tee section from turbo nipple to wastegate and top solenoid nipple??

Subaru 3 port boost controller: The top solenoid port is the air inlet (which accepts pressure from the turbo compressor), The middle port is the outlet (which sends a portion of pressure to the wastegate actuator) and the lowest port is the vent (which sends bleed pressure back to the pre-turbo intake system).

Line No:11 is redundant/deleted on your model. Use line No:12

No. Overall there is only a small difference between them.

Yes. The original turbo would have been a VF13.So he upgraded to VF18 primary.

This is a ball bearing turbo should spin easily with little effort. Wastegate should be firmly closed via the actuator arm and difficult to open by hand.

Straight bolt up. However unlike the VF14 the VF27 has no wastegate actuator so you will need to block off hose No: 8 from the solenoid box
