I am going to atempt to make a air pump simulator for less then $10 with parts from Radio Shack. I will make a DYI with part numbers and wiring diagrams. I have a good idea of how I will make it start simulation and it should be a easy unit to make. Anyone interested?? |  |  | | 11-16-2008, 06:51 PM | #2 | | Senior Member Join Date: Dec 2007 Location: Gulfport, Florida Posts: 3,208 |

I like to run my car with no cat or air pump and get no error codes. Simulator cost $200 to purchase, I'm making one for less then $20 | | | | | 11-17-2008, 07:21 PM | #6 | | Senior Member Join Date: Feb 2008 Location: Oceanside, CA Posts: 421 |

Air pump is my only code and I removed it cause I needed the room for the meth system. I finished the unit for $12.45 and I'm testing it tomorrow morning when the car is nice and cold. If it works I already have a DIY written up with pictures ready to post. | | | | | 03-11-2009, 05:46 PM | #8 | | Senior Member Join Date: Mar 2005 Location: NJ Posts: 1,625 |

I need to do this, because I am using BMP shorty headers, and the m52 didn't come with the pump at all | | | | | 01-22-2011, 12:29 AM | #10 | | Junior Member Join Date: Jan 2011 Location: Chattanooga TN Posts: 3 |

276-0149 PC Board: 1.99 | That is because you bought 2 pots and 2 relays for the dual bank version. BTW super nice soldering job on your board. You should start making these for people. You doing quality work... John Smith | | | | | 01-30-2011, 07:48 AM | #12 | | Junior Member Join Date: Nov 2010 Location: Delta BC Posts: 4 |

I went to my local Radio Shack today to buy the parts to put one of these together and they only had the enclosure and pot's in stock! If 5liter's are as good as JohnBoy says, I would be very interested in purchasing one from you! Do you think you might be making some to sell? I'd gladly pay a fair price plus shipping  | | | | |
