Do you run this EBCS with the restrictor pill in place or not, on a 2Lt STi with VF35 Turbo. ??

Now that is a pukka site!!

I was wondering why i was getting such high boost spike and after reading various bits and pieces online i have come to the conclusion the pill restrictor has to go

I was hoping you would reply to this Duncan as i knew you knew for sure. Thanks for confirming this :lol:

Nice one :thumb:

I seem to be having to run some quite high WDGC to hit boost using the prodrive solenoid. I'm sure i have this solenoid hooked up right in interrupt mode. Before when running with a pill the WGDC wasn't anywhere near so high but it was spiking.

Do i have a leak somewhere after the turbo?? Maybe turbo to TMIC or TMIC to throttle body hose??
Or perhaps leak before the Turbo, uppipe side?? I can't hear any exhaust blowing though or smell any unburnt fuel like when the OEM uppipe was leaking via the flexibit on my old WRX engine, so i can only assume the prob is up top somewhere.

Any suggestions??

I found the WGDC were quite a bit lower with it - what are you calling high and for what boost?

Whereas before i had 48% WGD for 20PSI peak with the pill, i am now at 78% for 21PSI peak.

I must have a leak somewhere is all i can think of as 1PSI in the grand scheme of things even with this VF35 is bugger all and shouldn't require the extra 30% WGD.

For the extra 1PSI and with the Prodrive BCS i would have expected the WGD to at least remain the same even with a 1PSI boost increase.

Also with an increase in boost i would have expected MAF to rise even a little bit and it hasn't, so i need to go through everything at the weekend and make sure everything is clamped up and airtight.

I'll see what turns up.
