Quick AEM EMS advice
Hey guys,
Just had a couple of questions before I get retuned later this week due to my increase in boost and electrical cutout install.
I have had the car for about 4-5 months with the ems turbocharged. The setup and tune have seemed to be solid but just had some questions which may or may not be a concern. I wanted to check before I see the tuner again to ask him to change it worst case scenario.
First, I see that in the o2 feedback settings, its setup as min 0 and max was 3500 which I increased to 5000 since i did see a change while driving. It seemed under 3500 it was on the mark hitting 14.7 but then right after i went a bit higher, pressing the throttle slwoly, it dropped down to 14.2. I also noticed for some reason that it went down at certain rpm's with light throttle to 14-14.4 instead of staying at 14.7. I wanted to ask him to increase that 14.7 to 15 for normal crusing and driving. Does it need to get completely retuned for this to happen or can he just change a number on a table?
When I release the gas, the car goes lean, around 17.5-18, until i hit the gas again. Is that normal? I read somewhere the decel afr probably wasnt setup but can it this cause engine damage by chance?
Finally, when the car is cold and you turn it on, it starts at 14.9 and then drops down to low 13's. I think he set that up because he recommended it to run rich when the car is cold, but if i remember correctly, the honda ecu never dropped that low and was around 14.7 pretty much the whole time. Should I ask him to keep it at the crusing afr when it starts up?
Thanks in advance.
