Turbo Installed - Post Test Drive Questions/Problems
My turbo is installed along with the MAF delete, IAT install, 550cc injectors, FM duel feed rail and LC1 WB. I free air calibrated the WB as well. I had installed the 550's before the install and scaled them. I am running 10e HR code.
WB is showing I am running pretty rich at idle at about 11-12:1. I run pretty rich across the board at all rpm so far too. When I get into boost I spool to about 4000-4500rpm and/or about 7psi and then the car just falls on its face hard almost like a fuel cut. I am imagining it is just an over fueling issue right now. Any help? I dont mind running it really rich so I can get through all the gears and full boost and then scale it back rather than run it lean. I havent even really touched the fuel tables to tune yet because I cant really stay in boost and since I have been running so rich.
It also sometimes takes a couple tries for it to start now. Again, I think its a fuel issue. It starts and runs fine when it catches though. Revs smoothly throughout with no load. There is definitely some over run fuel being burnt as well.
also every time I open Megatune now it asks me to send and burn to controller even though i keep unplugging the ignitor and saying yes. do i need to keep unplugging it? Why I am getting prompted over and over?
Air/Fuel gauge on Megatune obviously doesnt read anymore, and Lamda gauge is in volts, is there a WB A/F gauge I am missing?
