First Log with DSMLink
Very happy with the results. I need to update all of my information so you can see what kind of mods I'm running.
This was on a built 2.0, FP3065, 25 psi, 93 octane, and a bunch of other stuff..... |

The fact that Boost estimate is way high and your having to pull so much fuel leads me to believe you have a large boost leak.

Post it on Link Forums, they should be able to explain it better. But just from looking at it, yeah, it does look like a boost leak.

Boost leak test it.. 52lbs a minute airflow aint to bad either.
I just looked at your fuel and man you are pulling a lot of fuel out. What injectors are you running?

FIC 1000cc injectors, MKIV TT Supra Pump (Rewired)
Car held 30psi on the boost leak, not a single lb let out.

Are you using methanol injection? Something isn't right. 25 psi on 93 octane with that much timing, pulling that much fuel..

^^ I agree. It seems very odd that you have 0 knock running that lean unless you have meth or were running race gas. You also need to put in your car specific information into your logs. You do this by hitting F4, click on A/F Ratio, and click on the properties button. Repeat for BoostEst and HP.

No methanol injection, 93 octane. Hell, I was just as confused as you guys were, so confused that I ran the tank dry and refilled it with 93 from the local 7-11 up the street. Made another run and logged the same exact thing.

I am telling you man, go to the source. Tom and Dave don't like it when we post outside of the Link Forums, especially when its his product we are using and you have problems. There obviously is something wrong, if you have completley dried out the tank, then tried it again, and it done the exact same thing. Everyone here can view it, but only true members can view link forums.

Something ain't right for sure, lol. 52lbs/min and 264 hp?? Thats more airflow then dsmlink is reporting for me and I'm just a bit over 460hp and bottom 11's........
Your a/f ratio properties aren't even set up. Where's the wideband???

He's running a MAFT, which you can see by it locking the intake temp. This screws up the airflow numbers. Check out the dsmlink wiki and do the MAFT calibration to set up your airflow sliders.

Either his air metering isn't accurate or some of the air being metered isn't making it to the motor, hence why he has to pull so much fuel.

If I recall when I looked at it yesterday, the airflow sliders weren't even moved from 0 at any Hz level. Definitely needs calibrated at the least.

Your maft definitely needs calibrated. Do you have a wideband or a map sensor? Did you set fuel pressure to 37 psi with the vacuum line off?
