Need opinions on settings

[DSM BLUE TURBO]

Just got back from the track, and my car was faster with no mods what so ever. I know im running rich, but just get your feedback on what my AFC settings should be.

My car has the following mods:

3inch intake
blitz bov
lower IC piping
2.5 DP
2.5 catback
walbro 225 LP
550s

Im at work right now and will probably post what its set at later tonight. I dont have a EGT or A/F gauge right now.. Guys want to give me some help?

Its dependent on the amount of boost you run but I figure 550s should be around -25%

 

[DSM BLUE TURBO]

-25%??

all the way across?

Do you have a modded/hacked MAF? IMO, I would lean it to MAYBE -10 IF you are running a factory MAF. Don't risk your engine w/o a logger or at least EGT/AF.

First of all, we don't even know what year your car is. That, like, is kinda important.

Second of all, trying to tune a car without a datalogger is STUPID, so trying to tune without even an EGT gauge is, well... I can't think of an acceptable word for it.

Get a damned logger, and get one fast.

For now, if your MAF is hacked at all, I would sya go to -5%. Yes, -5%.

-25% is almost guaranteed to damage something, if it's a 1g with a hacked MAF.

Hmmm.. for some reason I assumed the car was a 2nd gen. I know with my 550s I ended up setting it at -25% across the band running 15-20lbs of boost. This ofcourse is a very rough estimate and all your tuning should really be done with a wideband if not atleast a logger and EGT.

2g.. and my logger cable is in the mail. MAS, screw back out flush.. any more ideas?

-10% MAX until you get the logger. And get an EGT gauge. No offense, but why did you even put the 550's in if you didn't have ANY way to check to see how the car's running (read logger or egt gauge). You could do serious damage to your engine before you even get the logger; so I don't think putting them in that early was worth it.

And by the way, what WERE your settings; you said you already ran them at the track. You could have been pig rick and the car's slow, or super lean, timing getting pulled way down, and melting things...
