Default AP stage 2 acn tune help

Hey i just upgraded to stage2 and i ran this log after i was running it for a week.

I was just wondering if you guys can take a look at the log and tell me if it seems everything is running ok. I havent had any problems and i followed cobbs video but i'm still kind of a noob when it comes to reading the log.

Thanks for the help

Log looks good. You are underboosting a little, but not too bad. Your load is a bit high for a stage 2 WRX. Are your outside temps really cold there? Sometimes excessive load can indicate a boost leak, but your long-term fuel trims look OK. I would at least double check the intake tract for leaks especially if you pulled off the intercooler to install the downpipe (a pressure/smoke test would be a good idea)

Yeah it was really under boosting before so I had to use the HWG map. Where can I go to run a test like that to see if I'm leaking anywhere?

I live in ca so it's been a little cold here for San Diego. I did do the test in the morning right after the engine heated up for about 5-10 min. Do you think that could have caused that issue??

clark turner, he's a member on here and his maps are worth the tune. He did a great job on my map and I have never had any issues. http://www.clarkturnertuning.com/

You can make your own pressure tester and use an air compressor to test (search for DIY pressure tester). You can also see if you have a local shop that has a smoke machine for testing intake tract leaks. When you pull the intercooler off, the most common source for a leak is the BPV, especially if you re-used the gasket. If you did, get a new one and torque the BPV bolts to spec. Also check for loose clamps (although don't overtighten).

I'm just going to replace the gasket since that should be cheap. I can't seem where to find one online. I am on my phone but if you could throw a link up for a stock bpv gasket I wouldn't object

Also I can keep driving my car with this issue right? It's not going to hurt anything correct?

I forgot to also mention i'm running a catless dp with the tune could that be causing the problem you are seeing?

No, catless won't impact it. It is just a guess at this point. The load looks a little high for a stage 2 WRX, but it could very well be that high for your particular car. The best indication of a leak would be your long-term fuel trims (A/F Learning 1). They look OK in your logs, but they are reset when you install the AccessPORT, reflash a map, reset the ECU via AccessPORT or disconnect the car's battery. So, it would depend on how long you've been driving since you performed any one of those procedures. I would drive for about a week without performing any of those and then check your A/F Learning 1 A, B, C, D values. They should generally be within +/- 5% with any outside about +/- 8% may indicate a problem.

You have a borderline value for one of the long-term fuel trims. Being that it is negative and given the high load that is reported, I would say there's a chance that you have a boost leak. Best way to determine this would be via a pressure or smoke test. There's some DIY instructions on Nasioc for creating your own pressure tester (if you have an air compressor) and some shops can do it (or can smoke test the intake tract).

Yeah, you'll be fine. There may not even be a problem.
