Hey all, am useing omni 4 bar to log boost through evoscan.i have made all the changes in evoscan and boost logging seems fine. Am useing tephra v7 88590715, am alittle confused as to which omni 4 bar settings to select in ecu flash under map sensor scaling. These are some of the options listed, omni 4bar psia8,psia16, boosterrorpsi. Right now i have psia16 selected. The car runs and drives without any problems, but just wanted to verify my selection is right. Thanks in advance

 

Just changing scaling has no effect on the tune, just changes how you see it in ecuflash.

Change ALL the boost related table scalings to Omni4bar. If the default was psia16, use Omni4barpsia16, if the default was 8, use the 8 scaling. You'll know when its not right as all the values in the map will be waay to high or waay too low as soon as you change the scaling. DO NOT overwrite the waay to high/low values with what you think should be in there. If the values arent close, the scaling is wrong. They will change going from jdm3bar to Omni4bar, but you'll see what I mean if you mess with it. Also double check all the tabs in the map definition.

 

Thanks man, makes sense why the car always ran fine reguardless of what scalings i used....thanks again

Also see ur running sd in ur sig, was it a real pain to setup? How's drivablity?
Any lean spikes during tip in

 

love SD. Took a few hours to get running decent and a few weeks to dial in. No real issues. There are plenty of folks that can help you get it sorted out if you run into issues.

 

Your car is a 8 or 9, if its a 9 I may require your help pretty please...lol
