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 | Just got back from Radio Shack..... 1 - Component PC board (#276-149 $1.99) 1 - Component Project Enclosure (#270-1802 $2.69) 1 - SPDT * PC relay miniature 12vdc 10V (#275-248 $4.69) 1 – 5V Voltage regulator (#276-1770 $1.59) 1 – Zener Diode 5.1V (#276-0565 $1.39) 1 – Package assorted LED’s (#276-1622 $2.99) 1 - Cermet Potentiometer 1K-ohn 15-turn (#271-0342 $2.69) So I’m at $20 bucks so far but I purchased a few extra items that I might not need. ‘ Picture of parts for simulator: | | | 11-16-2008, 07:05 PM | #3 | NOBODY F's with the Jesus Join Date: Oct 2006 Location: Ventura California Posts: 7,824 | WTF is an air pump simulator??? __________________ 4 MORE YEARS BABY!!! | | | 11-16-2008, 09:28 PM | #4 | Senior Member Join Date: Sep 2007 Location: asdfasdf Posts: 10,002 | Quote: Originally Posted by cooljess76 WTF is an air pump simulator??? | I'm going to guess it's something to delete the air pump while fooling the computer into thinking there's one still there | | | 11-17-2008, 01:56 PM | #5 | Senior Member Join Date: Dec 2007 Location: Gulfport, Florida Posts: 3,208 | Quote: Originally Posted by tiFreak I'm going to guess it's something to delete the air pump while fooling the computer into thinking there's one still there | Correct. 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 | For the afrter cat sensor are you ganna tap into the elctronic or just relocate the sensor? __________________ 2003 Z4 2.5i 2002 Ducati Monster S4 | | | 11-17-2008, 09:34 PM | #7 | Senior Member Join Date: Dec 2007 Location: Gulfport, Florida Posts: 3,208 | Quote: Originally Posted by lpcapital For the afrter cat sensor are you ganna tap into the elctronic or just relocate the sensor? | Relocated it 1.5 years ago. Never had a code since. 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. | | | 11-17-2008, 10:02 PM | #8 | Senior Member Join Date: Feb 2008 Location: Oceanside, CA Posts: 421 | Quote: Originally Posted by xxxJohnBoyxxx Relocated it 1.5 years ago.

However I'm wandering if Nick can erase it from the ECU... If he can get rid of the DISA, I think he can play with that too... And maybe even the after-cat sensor... __________________ 2003 Z4 2.5i 2002 Ducati Monster S4 | | | 11-18-2008, 01:07 AM | #9 | Senior Member Join Date: Dec 2007 Location: Gulfport, Florida Posts: 3,208 | Quote: Originally Posted by lpcapital Great, thanks!!!

I just got a flash from Nick last Monday and we spoke about how to make the air pump simulator. The after cat O2 is real easy to fool by just relocating the O2 out of the exhaust stream | | | 11-18-2008, 01:09 AM | #10 | Senior Member Join Date: Feb 2008 Location: Oceanside, CA Posts: 421 | Quote: Originally Posted by xxxJohnBoyxxx Nick does not have code available (Public) to disable emissions items.

The sim came on when the DME asked for air pump and fooled the DME with a lean signal. It stayed on for about 2-3 minutes then turned off. No error codes for air pump for $12.45 and a little soldering. I'm at work but will post the DIY today. | | | 01-02-2009, 03:22 PM | #12 | Senior Member Join Date: Dec 2007 Location: Gulfport, Florida Posts: 3,208 | DYI with photo's, part list and drawing for 1 & 2 bank simulators located in Knowledge Base in this forum. A big thanks to 318ti.org for not deleting this like the other forums. Works perfect. No CEL's No issues reported on several sims in use. People have emailed me and used this on LT1 corvette, BMW M3 E36, GM LT1 Impala. I can be twaeked to use on any SAP system. Wide or narrow band O2 sensor not a problem Remember this is not for cheating emissions. It is for track cars, auto-cross or off-road cars. | | | 03-10-2009, 02:39 PM | #13 | Senior Member Join Date: Mar 2005 Location: NJ Posts: 1,625 | John... sorry to resurrect - but this is great stuff & so I have 2 Qs! 1- will you sell one fo these to me, for lets say $40? 2- how did you plug up the whatever hole was left after you removed #17 from photo below??

You will only need one vacuum line going from the nipple on the TB to the FPR: basically line #1 in your draw will plug straight into the TB. John, just to confirm: does the ECU diagnose the solenoid (#10) or no? I don't think it does, but I wanted to make sure. __________________ 2003 Z4 2.5i 2002 Ducati Monster S4 | | | 03-11-2009, 11:56 AM | #15 | Senior Member Join Date: Mar 2005 Location: NJ Posts: 1,625 | what about # 17? if that is removed - I may have to plug up something, I'm sure - on the header/cat, no ??
