i keep my max boost set at 15psi on the dot.. occassionally i will end up having to turn my boost control down a hair because it ends up boostin to 16 - 16.5 which it isnt just a spike it will stay there. this has happened about 3 times in the past 5 or so months.. i change nothing but yet i have to cut the boost control back sometimes.. and a few days later i will have to turn it back up a hair to get back to 15 psi?? only thing i can think is if the air is cooler or something it has an effect but i dunno.. just wondering. it hasnt happened recently but i figured maybe someone else knows about air temps and boost relation if any.

 

id bet your seeing differences in barometric pressure

 

you will boost slightly more in cooler denser air without some minor correction.

 

i guess.. i norm would not care but i got this setup tuned to the max and i cant risk blowing it up... hopefully it dont happen again.

 

yup, i get 2psi of creep on cold days. and its just like you said, its not a spike, it comes on at 12 and holds 12psi till redline.

 

Yes, you will see more boost on colder days and less boost on hotter day. Your best bet is to get an electronic boost controller, or run eCtune and use its Electronic boost by gear control, which has the ability to run Closed Loop operation, Meaning it'll adjust EBC duty to maintain taget boost levels automatically. By doing one of these 2 things you should be able to get a constant boost level regardless of ambient temps.

 

as will hondata s300 w/ boost control from looking at my smanager software

 

Yes, S300 offers electronic boost control, but its not closed loop, it does not monitor actual final boost and make corrections to the seleniod duty to keep it on target. eCtunes EBC is more advanced.

can AEM EMS do it?

 

Yes AEM can do full feedback boost targeting.
