It's been a while since I've had the evo on the dyno with it running properly, but yesterday it finally worked out. The day before I had my doubts, as of course I blew open a massive 2" hose in my hose connecting my bov to my UICP and the car ran like crap.
I spent some good time on the street with my laptop and LC-1 getting stuff dialed in so as to minimize the headaches on shane, but really I probably only made things worse
Anyways, mod list (power stuff only, of course):
Buschur Racing 3" TBE w/ bullet testpipe
Buschur Racing Intake kit
BR Deluxe FMIC kit (3.5" core)
BR Upper IC Pipe
OEM IX BOV
HKS 280 cams
ARP headstuds
BR Ported/Coated Exhaust Mani
Ported Turbine Housing
OEM Evo IX turbo
BR SS O2 Housing
BR Ported Intake Manifold w/ EGR delete
BR 65MM TB
Walbro 255HP fuel pump
4x Kracka Vent setup w/ ebay catch-can
Aquamist HFS-1 Alky Injection Kit
FIC 1050cc injectors
GM BCS
Evo X MAP sensor
Innovative LC-1
Tephra v5 ROM w/EGT Elim & Direct boost mods
Pump gas (BP 92), ~24psi, tapering to 22psi (woot! ecu-controlled boost!)
Boost curve needs some work, but this is my low-power tune, so it doesn't get as much attention as the alky tune
Anyways, on to the fun part!
Pump + Alky, 28.5psi tapering to 22psi
As you can see, the turbo is just out of steam and dispite my best efforts and 100% DC on the GM BCS, it just won't hold more boost up top:
Overlay, what can alky do for YOU?!?!
To flip between these two tunes, I have but to push the power button on my DDS gauge (part of the aquamist kit) and bam! The power is there
While on the dyno, I tested out Tephra v5 mapswitching as I am using it for a failsafe. If the alky fails, I drop down to the pump gas tune. We did a pull, and I flipped the DDS gauge off right around 5000rpms. This seems like the worst thing you'd wanna do, but I wanted to be *sure* it was working!
Flip it off, and boost drops:
And AFR stays nice and safe
Success!
