    Mini Gsx build

    "I just want to make a tiny bit more power"...said every DSM owner before dumping 10k into a car worth 2k.

    Help Diagnosing Sound

    I found the issue. The adjustable cam gear bolts came loose, so the exhaust cam was sliding all around. Applied some locktite, re-torqued, now it runs great.

    Help Diagnosing Sound

    I can't see any visual issues with the springs and retainers - then again, I don't really know what a problem with those would look like.Would I only be able to detect a problem with the lifters if the cam lobe is all the way up? I don't yet have the socket to turn the cam gear, so I just...

    Help Diagnosing Sound

    Immediately following a pull today, my car started stumbling really bad and making some rather loud knocking noises. The knocking is not consistent, and doesn't follow a particular rhythm. I've been told one (or more) of the lifters may have failed. I pulled the valve cover off and wasn't able...

    ECMlink Real Airflow with Speed Density

    Thanks everyone for all the replies. Looking at all this, I do think the SD table being inflated at certain points is likely the cause for the airflow inflation. Doing some quick math to back out that inflation, looks like I'm actually closer to 55lbs/min, as bastard DSM originally guessed...

    ECMlink Real Airflow with Speed Density

    Interesting. Well, I did do some of my fuel tuning in the config settings, so maybe that's causing discrepancy?Low to mid 50's sounds more reasonable - do you have any math or logic behind that?

    ECMlink Real Airflow with Speed Density

    Couldn't find any solid info on this, but I've heard the airflow measurement in ECMLink isn't accurate if you're running speed density. Well, I'm running SD, and my log (attached) says I'm flowing 67lbs/min at 25psi on my 6-blade hx40 on the .70 a/r housing. I'm just starting to break in my 9:1...

    2G sometimes it pulls, sometimes not

    I've had this problem before. Turned out to be a slit in a vacuum line. As the car heated up, the inside of the slit in the rubber hose would sort of melt and fuse together (it was close to the manifold), and seal air properly after it cooled down. But when the boost pressure eventually reopened...

    Resolved Tubular manifolds

    My advice would be to stick with your evo 3. In my opinion, far more downsides than upsides to running a tubular manifold for most people. They run hot, crack, and most require significant rework to the downpipe (which can cause other issues).My preference is to run a ported 2g or evo3 on my...

    Resolved Tubular manifolds

    I've had it with cheap tubular manifolds cracking, so I bought this one from MAP:I'm trying to get it on this week - spacing is a bit tight with the hx40, so we'll see.

    General Lean Idle When Warm

    I just recently got a new long-block 9:1 2.3 stroker and a JMF SM IM. Turbo, injectors, ignition setup all the same as with my last setup/tune on my stock 2.0 w/ stock IM. I basically kept the tune the same, as I figured that'd be enough to just get the car drivable.At cold start, car idles...

    ECUflash 9:1 Peak Ignition Timing

    Yeah, that'd be helpful. Thanks.

    ECUflash 9:1 Peak Ignition Timing

    How much boost? (and did you mean 6psi more, or 6 degrees more)?

    ECUflash 9:1 Peak Ignition Timing

    I'm going from a stock compression 2.0L to a 2.3L .30 over 9:1. I'm curious how I can expect my peak timing to change.I've searched around a bit, but haven't been able to find consistent info.For example, if I was running 35psi (50/50 e85/91) from an hx40 on my 7.8:1 2.0 with 17* peak...

    just dont get it.

    Probably a super silly question - any chance this ECU is reflashed, and is currently in valet mode?
