I have completed my final version of my air pump simulator and it passed the testing this morning with no error codes. All parts from Radio Shack and total cost $12.45. No more $150-$200 to buy these online. I will post the complete DIY this evening when I get home from work. Here's a picture of... |  |  | | |
Would someone be willing to build me one of these for like $20 bucks for my S52 swap? I really don't have the time but my car will need to pass emissions. | | | | |
It is hard to find someone to make one for you when you want to use it to pass emissions. These are to be used for track or off road use only, this is to protect 318ti.org for posting this DIY. If the intended use is track or off road then it might be easier to find someone to build one for you.
Also $20 will barely cover the parts for a 2-bank which you will need for a I-6. The $12 one is for the 1-bank version for the I-4.

Ah I understand, how do you make a two bank system? I guess I'll have to wait to do the delete till I rally the car, time to start looking for a secondary air pump  $$ | | | | |

It is all in this one thread. If you need any help ask or email me and I will help. People are running these on all kinds of cars: Chevys, Fords, Imports, Etc. I was getting a lot of emails in the beginning but it has slowed down lately. Good luck, John S | | | | |
Hahah no it's cool, it was late and I wasn't paying attention, Thanks for all your help though. | | | By bsaint on 10-29-2010, 12:02 AM |
Anyone who is good with these want to make me one I'll paypal you, Don't feel like spending the $200 for the AA one and not as good as some of you with wiring etc. Let me know thanks!! 97 E36 M3 s52 $40 shipped? and a copy of my last DVD "Speed of Dark" email me Boondocksaint@comcast.net | | Last edited by bsaint; 10-29-2010 at 12:13 AM.. | By mpire on 01-19-2011, 07:02 AM |

I built my air pump simulator and a DISA bypass into the same box... but I have yet to install it. Strange thing is neither my DISA nor Airpump are hooked up (removed actually)... but no CEL. The DISA throws a code, but only the PEAKE tool can find it... and the missing airpump has no code.
I do have a reflash from TT (NickG). Perhaps that is helping? | | Last edited by JP422; 01-19-2011 at 08:49 PM.. | | |
Nick G's code stops the CEL but the code is still there and can be found so your right on the DISA no CEL but still has code.
Don't worry the Air Pump will come back to haunt you give it a few runs where the DME calls for it and the O2 does not detect a lean condition and it will throw a CEL (Air Pump InOp)

Very compact so I feel your pain. A lot of people are like "what" when I told them $75 for one. I don't make them anymore but might do a run of like 5 if I could get 5 buyers. They are a PITA to make Good job man, you saved $188, much respect from me to you John Smith | | | By JP422 on 01-19-2011, 08:51 PM |
lol... ok, well, mine is all ready to install anyway... I'l get around to it someday. Thanks for your tips!~

I would like some insight on how and where to wire in LEDs for various stages.
I know someone posted something along those lines.
I have an 12v LED that lights whenever its powered up. | | | | |

I have an 12v LED that lights whenever its powered up. | It should only light when the unit is on or in simulation. Here is how it works...DME calls for Air Pump. Simulator goes active and removes O2 signal and inputs 200mv signal to DME telling it the exhaust is lean or it is being injected with air. The DME is happy thinking the air pump is working. DME calls for Air Pump to turn off and simulator turns off. There is no power to simulator so it is a pass through devise and you O2 signal is just passing right through it and your DME is gtting it's O2 reading like you never cut that O2 signal wire when you installed the simulator. I hope this explains why the LED is only on a short time when you first start the car in the morning and maybe better understand how the simluator works. I don't think there is a post for different stage LED's since there is only one stage for the Air Pump John S | | | By mpire on 01-19-2011, 09:44 PM |
Probably so. I assume you just wired in the LED directly to the power leads from the air pump? At least thats what I did.
I am testing it on the wife's car first just to be careful. | | | By mpire on 01-27-2011, 03:09 PM |
So I am having trouble getting this to be exactly 200mv. I get a fluctuation of around 10mv.
Also there is no fuse on this thing, so I think I will need to make some modifications. | | | | |
