boost pid

[Earl H]

I use a similar formula however at Idle, my boost guage and boost controller read 13psi vacuum and the pid yields ~ 6 psi of vacuum. Should the formula be adjusted to sync up with the boost guage. Its an autometer guage and Blitz EBC btw.

Formula:

(({SAE.MAP}-102)*0.14503)

Actually, your boost gauge and controller are reading 13 inhg (inches of mercury) of vacuum. PSI= inhg/2 (about)

Here's one you can use ,this pid will only show Gauge pressure(ie no boost will read 0) .I used 102 for baro.



*CLC-00-992
PSI 0.0 20.0 .2 "(({SAE.MAP}>102)*({SAE.MAP}-102))*0.145"

thanks ill try that

[Cablebandit]

works great...thanks though my eboost2 and map sensor read 1 psi diff with the map being the lower of the 2.

Where and how do you go in Efi Live to enter these settings? I would like to make a boost gauge to compare to my autometer boost gauge. Thanks.
