EGR Simulator or AIR simulator? Has anyone looked into building either an EGR simulator or an AIR simulator?
If one could be put together with just resistors/diodes/capacitors/coils, then it would be a much cheaper way to pass all readiness tests without the more expensive purchase of LS1Edit/LT1Edit.
If anyone can tell me how to do it, I am good with a soldering gun!

Re: EGR Simulator or AIR simulator? You can probably get by with resistors until the computer starts looking for differentials. Then you're screwed. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
When the PCM injects air, it looks for an O2 sensor differential (low O2 mV reading indicates air in the exhaust stream). If it doesn't see it, it knows there's an AIR system malfunction.
When the PCM turns on the EGR valve, it looks for a MAP differential. No change in MAP pressure, EGR system malfunction.

Oh, Chris, by the way, can I borrow 500 bucks? <img border="0" title="" alt="[Razz]" src="gr_images/icons/tongue.gif" />
