Hey hows it going? I purchased my Speed 3 about a year ago. I work for GM at a Buick/GMC dealer as a technician. Customer blew up their motor and sent #4 rod out of the block. My dealer decided not to throw a motor in it and resell it. I picked the car up for 800 dollars. Not too bad if you ask me. The car had a AEM Intake, upgraded compressor wheel, Turbo XS Downpipe, and 3 Port EBC. Im pretty sure the idiot put those parts on and didn't tune it resulting in the engine failure.
Got myself a Gen 2 motor, turned out to have upgraded HPFP internals. EGR Delete, PCV Plate minus the catch can. Upon removing the engine I found the clutch and flywheel completely smoked. Installed an ACT Flywheel/Clutch setup as well as new slave cylinder. Purchased an Access Port at the same time to not make the same mistake the PO did. Installed a 3.5 bar BAT sensor so I wont have to worry about that later when I run more boost.
Car was extremely loud as they had done a resonator delete so it was basically straight piped. Put on a 3" Turbo XS exhaust shortly after as I felt bad for anyone driving near me, my neighbors, and the sheer embarrassment of being the loudest car on earth.
I found that my BAT and heat soak was an issue so I installed an FMIC setup. It seemed to help overall plus it removed clutter from the engine bay. Over the past weekend I installed an XS power turbo manifold and External Waste gate setup. I have been fighting issues getting the car to boost over 15 psi and for the life of me cannot figure it out. This has been happening before and after the Manifold/EWG install. I know the turbo can boost over that amount. There was a cracked vacuum cap on the IWG actuator which led to its opening being delayed. Corrected that issue and the boost level dropped down to 15 psi area when running the IWG. I wanted to upgrade the factory turbo manifold as it's design is crap which is why I went to the new setup.
I used Cobbs Stage 3 map as a base, modified the WDC, Boost Target tables. It should be running Boost Based targeting only per Cobbs instructions/map description. I understand that the ECU uses multiple logic to obtain peak boost. Cobbs tuning guide seems to be horrible as it doesn't exactly dive into many specifics. I have gone back and forth with using the OTS WDC/BTT tables to modifying those and back again. Just cant seem to get it to run more than 15 psi. I have smoke tested and boost pressure tested the engine and found 0 leaks. Boost also seems to come on late with my achieving peak psi at around 4200 RPMs then tapering off down to 13.5 up to redline.
I wont brag and say I know everything about tuning, however I have a turbo Miata that I run a Megasquirt 3 Pro ECU. The MS3 Pro is pretty damn simple to use IMO. I have a boost target table and a WDC table. Getting the Miata to hit its boost targets has never been an issue. If I want 20 psi but don't hit the numbers I can just increase or decrease WDC till I hit the target.
Im sorry for the long drawn out post but I figure the best way to introduce myself would be to describe the car, the issues it currently has, and to ask you the community for help. Thank you for any advice you can give. I look forward to working with you all.
