Try unplugging the arc2 and bypass it just to make sure it's not the problem. I'm running a arc2 also. It did fail once but I would get a backfire while trying to start the car. They do fail occasionally. From there it it is a guessing game. I would check the ecu see if you have any bad...
Installation of filter media inside the catch can gives the vapor droplets something to hit and condense causing them to fall out of the air and accumulate at the bottom of the catch can. Adding a vacuum line to your intake will only eliminate any steam or smoke coming from the filter on the...
Do you log knock and are you getting high knock readings going into boost? Knock or phantom knock will cause these same problems. Especially with a 1g cas into a 2g ecu. Just a thought.... In ecmlink you can ignore knock below your set rpm to deal with this issue. I don't know how it is dealt...
4 pucks are generally grabbier. How was the condition of your mounts when you had the trans out? The soft rubber will contribute to wheel hop. I'm running a twin disk and my solution was some diy solid mounts after the polyurethane inserts failed.
I would check the timing in the low load cells . I had the same problem and setting them all even at idle helped quite a bit. Any exhaust leak can cause massive fluctuations in your wideband. You can monitor your iac value with link to get an idea of what it is doing.
You also have your coolant temperature locked in the ECU inputs tab. And in Tmngmaxoctane tab I would change 0.3 1000 and 0.3 1250 both to 5 degrees during setup.
You could try setting your first 3 timing cells from left to right in the top row at 5 degrees. Then adjusted your biss screw until your iac reads 30 at idle. If you're ecu is trying to raise idle. It may be increasing timing in that area leaning out your mixture. Just an idea..
IIshot a quick vid of my car for you. Fuel pressure should not rise under vacuum. The terms 1 to 1 or 1 to 4 mean boost pressure the first number and fuel pressure the second number. 1 psi of boost will rise fuel pressure 4 psi 1-4 as an example. Having it teed off the manual boost controller...
Take the boost controller off and blow in one end while adjusting the knob. Fully closed no air should pass through = 8 psi waste gate spring. Fully open easy to blow through = 10 or more psi varies could be 18 psi fully open idk.
