Need to run rich on idle after install Turbo
Hi, I'm having problem with idling, I installed a turbo and using my local brand standalone ECU and having problem that the car need to be running quite rich on idle to be drive-able.
Now running AFR around 12, I tried to get it to 14-15 but it will cause engine to stall.
The ECU run just like a open-loop style, No MAF, No O2. Injector is 550cc and running a bit higher fuel pressure (43.5psi on vacuum hose on).
Thanks

What standalone are you using?
Sounds like its incorrectly tune. And are you using a map sensor?
if not using a map sensor and not using MAF. That's your problem.

It's local brand, name 'KKT' (only well known in my country, not really on intl).
I do already use MAP sensor, a Toyota 1.8bar. not really sure what car it came from.
