I came across a post saying that closed-loop should be *off* in boost.
Where is the ideal point to switch from closed-loop to open-loop?
I currently have it at 30kpa. So, I guess above that, the car switches to the VE table for fueling and ignores 02 sensor feedback. Is this ok?
I tried switching at 100kpa, it felt
like it wasn't building boost as fast and the engine was less responsive, so I set it back lower.
Also, I saw another table under VEAL in Tunerstudio. I was happy with my old AFR table, but this other one is 12x12 and has more resolution. Car feels good after about 2 hours worth of VEAL tuning and I'll continue to smooth out the VE Fuel table. Is there any reason why I should stop this and go back to the default (table 1)?
Finally, should PWM 2-wire idle control be set to PWM? Mine came with B&G setting. It seems to run better on PWM, but I don't know if I should change it.
