Air pump and turbo....
So I installed a turbo on my car and I have been waiting for those air pump delete kits to come in for about two months now....... so I have had a cel for about two months, I was wondering if anyone has their air pump hooked up with a turbo and if they r getting a cel or not, if ur not getting a cel please tell me how u did it.... thanks

There is no way to remove the airpump and not have a check engine light, while using the stock ecu. The S2000 is smart, its very difficult to fool. You will either have to leave it as is or go to an aem ems. I still have mine and it causes no problems, so I dont know why you want to get rid of if anyway?
Spectacle its called an FMU do ur homework before u say somthing like that..... and Artisan there is a airpump delete kit that doesn't throw codes its even for sale on this site but I'm wondering if there is a way to make an airpump work with a turbo setup... so I guess the real question would be if I hook up the airpump to the turbo intake would my cel go away, or would the turbo affect the readings...
^ You're turboing the car, AND worrying about heating up the cat a bit faster for proper emissions? Nah, forget it.
Here's the deal on our CELs, i think P0411? Under our driver side fender, behind the wheel, there's a special circuit that measures the current going to the airpump. If the current is out of spec (such as when the ECU is telling it to be on, but it's not because it's been removed by you), there's no 2-5V signal going to the ECU to report proper current.
So, it's simple, really. I posted this here a while ago, and soon after, bam, we get the eliminator kit. I lose a patent just like that.
It's in the manual. All this info. There's a time when the ECU wants the pump to run. It monitors the current at that time. If current is within spec, the Air Pump Current sensing device (looks like a black box.) sends 2-5V to ECU. If ECU doesn't receive the 5V, it throw P0411. Here's the box:

So, you make a little circuit, parts will run you maybe $15 from Radio Shack. The chip is 273-1857. It'll take 12V (from the relay by the AirPump), through the circuit, and output, oh say, 4.5V from it to the small connector coming out of the Current sensor. Or these 2-5V (that's what ECU wants) directly to Pin C24 on our ECU. That's the White/black wire on the Current sensor box, small conn.
That's all the Eliminator box is doing.
