Just got my MazdaSpeed CAI!

The guy with the CEL is running his BOV VTA.. I'm by no means an expert, but wouldn't running in recirc mode help?

[/quote]The guy with the cel is running recirc. He said he is taking the BOV off to see if that fixes the problem.

Well, I went ahead with the install despite concerns raised about the design of the Mazdaspeed CAI earlier in this thread. My impression of the design and build quality on a purely intuitive level is that it is nicely done, but I will wait to hear what the testing shows by those more equipped to carry it out. One think that struck me though, why did they go through the trouble of relocating the fuel ballast resistor? I departed from the instructions because it didn't seem to be necessary. I used the rubber mounting stud along with a lock washer as a replacement for one of the resistor bolts and put the CAI bracket on the other end of that mounting stud I bent the sheet-metal tab that holds the connector for the ballast resistor to provide a bit more clearance for the CAI but it doesn't seem to interfere with the routing of the CAI tube to have the fuel ballast resistor in its original location. Am I missing something? To me the install looks a lot cleaner this way... I will post some pics if anybody is interested...

Depends on the clearance you have in there. That piece of rubber is in there to allow flex as the engine torques over. If you did not leave enough room the intake may hit or rub on the ballast under load.

For those not paying attention

thanks for thread craping ppl well i had it scaned again today the code is P2187 lean bank 1 check all the lines the install its all cool but i did mess around with the elbo for my gauges got a new 1 cleared the code drove about 200k no CEL so i think its cool now

So the problem was not the CAI.

none of those are car is running lean

No, but misfires can be caused by an air/fuel ratio going out of whack, like if the ECU trying unsuccessfully to fix something. In this case it looks like it might have been a loose hose causing the car to run lean, but that just goes to show the ramifications of doing so.

Remember this discussion started before anyone pulled a CEL code. I still think it'd be beneficial if CAI owners (Mazdaspeed and CPE) could post their long-term fuel trims through the rev range, especially if they have data on what their car was stock, too.

I thought exactly the same thing when I installed mine. I couldn't find any reason to relocate the ballast, but I did it anyway.

The only reason to relocate it that I can possibly come up with is to allow it to breathe better. Its quite obvious that the fuel pump ballast gets real hot (hell it looks like a CPU heatsink), so by moving it on the CAI, it allows it to be more out in the open and breath better.

Thats the main reason I followed that part, as I thought about keeping it where it was, but I realized from the - I dont know - CAUTION HOT HOT HOT - sign, that it needs alot of open space to breath better.

Of course, it looks like it has enough breathing room still attached too, at least once that stock abomination airbox is removed.

It would be nice to get someone from AEM or Mazdaspeed to chime in as to why they thought it should be relocated.

p2187

Misfire
• Front HO2S deterioration
• Front HO2S heater malfunction
• MAF sensor malfunction
• Pressure regulator (built-in fuel pump unit) malfunction
• Fuel pump malfunction
• Fuel filter clogged or restricted
• Fuel leakage on fuel line from fuel delivery pipe and fuel pump
• Leakage exhaust system
• Purge solenoid valve malfunction
• Purge solenoid hoses improper connection
• Air suction in intake-air system
• Insufficient engine compression
• Variable valve timing control system improper operation

What mazda.... intake or not hasnt blown a purge valve????????????

Isnt it a 80% chance it will go within the first 10,000 miles??

yep I had mine replaced within the first 2000 miles on my ms3 and within the first 10,000 miles on my 04 3. I would get that purge valve checked.

lol I've had 4 of them all due to CEL's within 10K of eachother.

holy crap you have a lot of posts.

This pic is just with my phone, but I think you can get an idea of the clearance. I will do some testing just to be sure, but I believe that the axis of movement is such that the clearance won't be reduced as the engine torques against the mounts...

Quick test- Put the car in gear, E brake on and one foot on the brake, heal-toe the gas and clutch giving it some RPMS while slowly engaging the clutch(obviously not all the way). Have some one watch as the engine rolls to see if it hits. By the pic it actually looks OK.
