Safc Temporary settings for big16g

[maroongstman]

Hey guys installing some 550s and 190 fuel pump a little later, can someone give me their safc1 settings on the hi and low throttle so I can make it through the weekend or any other settings . Im going to the dyno on Tuesday to get properly tuned, but I still need to drive this car since it is my daily driver. Help would be appreciated, thanks guys.

Every car is different because of different mods. Your profile lists you as having a wideband so use that to tune. If I were you I would just leave it zero'd out and run stock psi, then slowly increase the boost until you start seeing around 11.0:1. Then add fuel and boost at the same time. If you have a datalogger that will help a lot with determining when you are getting knock and have gone too far.

Read that link first though and you should be able to base your car off of thiers to an extent.

Thanks a lot that is very helpful... I sold the wideband not too long ago, I should update my mod list rite now. I found a setup on there that is very similar to mine, but I dont have a fmic and I have 190 rather than the 255. Ill ###### put that tune in and see how it goes, what you think? Thanks again.

Do the blue wire mod and try to keep you o2 voltage as close to .93-.94 as possible for a safe tune.

Since 550's are rougly 18% Larger than Stock -15 should be a safe setting.

Thanks guys I installed the 550ccs and 190 fuel pump today. Put the settings on hi throttle at -18 across and the car is running pretty good. Im going to take it to get dynotuned on Monday, thanks for the temporory settings. I do have one bug that I havent been able to get out yet. It runs fine but sometimes a stutter comes on around 2500-3000. When I step on the gas more it goes away, so I guess it only comes on when Im coasting it.

Boost leak test of course. Could have a coupler sucking in extra air when you let off and it goes into a vacuum.

i had mine set at 15psi on my ported 14b 550s evo8 setup. . . was still rich but safe... turned boost up to 20psi on a kinked fuel line causing the turbo to blow the exhaust wheel out the exhaust after melting it off the shaft in the turbine housing... bad day. good luck with the dyno
