Hi!
I'm on my way for my very first attempt at upping the boost on a car.
Before that, I'd like to hear your opinion on these readings, I'd just like to make sure everything is in proper working order before turning up the boost:
(rolling start, lazy shifts barely past 6000 rpm)
AFR: 11.0@4000rpm, down to 10.2@6000rpm, 7.8psi
IAT: 115-120F, outside temp was about 70F. Rises about 1.5-2.0 degrees per second on hard acceleration.
Car is bone stock except for a larger compressor trim and a decatted exhaust. No boost controller or hacks.
More questions :
- "USER1" signal is an analog input that I connected to check the TVSV Actuator signal from the ECU. Why would it stay on 5V then fall to 1.8V on boost? Seems strange, I was expecting more like 0V/5V. Furthermore, isn't this TVSV supposed to limit boost on 1st and 2nd gear?
- Boost used to drop down to 5-6psi@6500 rpm on 1st gear, and to 6.5-7psi@6500 on 2nd before the turbo compressor upgrade. I don't know if that upgrade was of any use, or if my old turbo was just tired. What do you think?
