    AEM F/IC writeup

    Just intercept it like you did with the injector signals. The AEM will just pass it as is until you mess with the Analog A map. I had the best results by putting it in offset mode and just taking all cells that are in boost and putting them at a -.4V offset. Narrowbands oscillate from around...

    AEM F/IC writeup

    Which two wires? No one is perfect, but I've been over that sheet enough times to feel pretty confident about it.

    I think those are for people with matching teeth.

    AEM F/IC writeup

    You can have the wires right but not the MAF voltage and it won't start. Unless you've messed with the ignition or fuel maps, they should just pass the crank, cam and injector signals as is. The MAF however is nearly impossible to get right without fooling around with the pull down resistance...

    WRX 440CC Pros and Cons

    You don't need bigger injectors unless you plan on running more boost/power than the stock injectors can handle. It is somewhere in the 230whp range. At least at 100% duty cycle. I believe there is always a little headroom, and I am sure someone has put down more than that with a piggyback or...

    3" Downpipe Group Buy / Fire Sale - $275 shipped???

    I wouldn't worry if they are all gone. It seems like there are always a couple people who buy parts on impulse and then need money for something else before they install them. Just keep an eye on the for sale section.

    Msp is officially dead, where to go from here

    I know swapping a used motor in is the cheapest way to go, but I am always worried about the history of a junk yard motor. Definitely check the compression on anything you find. A non-running MSP is worth 3k tops. A running MSP can go anywhere between 4 and 7 depending on condition. So it is...

    Can't figure this one out!

    I bought mine from Protege Garage, but it's probably the exact same part. Doesn't sound like you need one yet though.

    Can't figure this one out!

    It is called the wastegate actuator (WGA for short) and yes it is a very common part to fail. I had two OEM ones replaced in the first 50k miles. I've had the ATP replacement on since then with no problem. Normally, you end up overboosting and hitting ignition cut before the actuator is bad...

    front clunk? could be the end links?

    Not likely. There are 3 bolts that hold the mount to the chassis. They would have had to cross thread all three or they would all have to come loose or break. The other side is just held in a with a single long bolt and it wouldn't matter if it was tight or not unless it fell out and you'd...

    Those camera pics look like something from a mid 00's flip phone. Have you put X thousands into your MSP and still carrying a five year old phone.... If you have, mad props for putting your priorities straight. Now break out that Canon point and shoot, then hook up the usb cable and transfer...

    GI: Replacement exhaust manifold

    Yeah this is why I haven't quit my job to start tuning cars yet. It's for retirement, when I have enough money I don't actually need an income. Where if the business breaks even, that's better than expected. If you actually do some research on the big name tuners that are "successful" you'll...

    boost question

    This really should have been made a sticky. http://www.mazdas247.com/forum/showthread.php?123792646-Hesitation-explained-with-pictures. As for the boost running high, did you try the tests I explained before? Have you blown into the WGA? Have you worked your way back on the lines? Have you...

    Mechanical pop when backing up

    O'reilly had front strut mounts for $28 each so I decided to go ahead and buy them while I had the struts out. Turns out they actually come with new bearings, so I'll call Jason and see if he'll let me return the OEM ones and get my $34 back. Oddly, one mount has pointed black studs and the...

    Mechanical pop when backing up

    So after convincing myself it was the strut bearings, I ordered them ($17 each, ouch) and finally braved the ridiculously hot garage to put them in. Nothing every goes smoothly for me but this time it was my fault. I must have overtightened the top strut nut on the passenger side because I...

    Anyone ever run wider wheels in the front?

    Wow, I wouldn't think it would be that obvious. Although, it looks like he has the same aspect ratio on both which would put a larger diameter on the front. I think ideally you would want an 8.5" wheel with a 245/40-17 tire on the front so tire diameter would be nearly identical. Keep the...

    Anyone ever run wider wheels in the front?

    Many cars come with wider tires in the rear to achieve more traction in the rear and not oversteer as easily. Corvettes come to mind. I know of only one car that ever came from the factory with wider front tires. The mid 2000's Grand Prix GXP had 255 on the front and 225 in the back to handle...

    Mine is not quite as bad as yours yet, but I don't think I want to go aftermarket. I got one quote for getting it rewrapped for $350. Kind of ridiculous, but I guess it has to be done.

    Looking Into '03 MSP

    I have a friend with a 626 2.5L that's in not so good shape he's looking to get rid of. I would love to do a KL swap at some point, but I don't have the room or time for that kind of project. Only 35 more years until retirement, then I'll have time for all sorts of projects that I'll be too...

    Glad to see there are a few MSPs still getting some love and attention. To AAC, was the steering planned before Outlaw won or was that hand picked for him? Either way, congrats.
