| This is the left hand wheel well area where the intake tube and filter will live. |
In the Z, the ECU senses changes in air flow that a freer flowing intake provides and figures that something is wrong with the car, dialing in a different air fuel mixture or even changing the ignition timing to “correct” what it thinks is a potential problem. Actually this is pretty common in many late model cars.
 |
| In the right hand wheel well there is a windshield washer reservoir that gets in the way of the filter and intake tube. We must move it for clearance. |
To correct this many manufacturers of cold air intakes log Mass Air Flow meter voltage and long and short term trims of the ECU and do a lot of careful tweeks to the placement of the Mass Air Flow meter (or MAF) sensing element and the size of the sampling tube to make sure that the ECU does not get data that is much different than stock and start correcting out the fun.

| The factory windshield washer reservoir and the its low profile AEM replacement tank that places it in a new position in the front of the car. |
This sounds like a good solution but what it means is that the tuning of your typical well designed performance intake system is now compromised by the engineers designing intakes not first for power but to prevent the ECU from getting pissed off, power production comes second. As a result intakes often do not make as much power as they used to in the good old days when adding a decent cold air intake was often the best bang for the buck mod you could install on your car.
 |
| First we install the bracket for the new reservoir in the front of the car behind the bumper beam. |
Enter AEM and ETI technology. ETI technology is AEM’s special programmable MAF voltage corrector box which plugs between the MAF sensor and the ECU. The box is programmed to correct the MAF signal so it matches what the stock signal would be regardless of how the intake is tuned.
 |
| Next we bolted the new tank in place. The new tank is protected by the bumper beam. |

Hɑving read this I believed it was very informɑtive.
I appreciate you finding the timе and effort to put this informatiߋn together.
I once agaіn find myself spending a lot of timе both reading
and commenting. But so what, it was still worth it!
