What exactly measures the "flow" thru an EGR cooler? How does the engine know or not know if a specific flow rate is met at any RPM? And can that target flow be altered in respect to what the ECM wants to see? Obviously it can be ignored completely.
I understand the full EGR vs. full block...but I'm just thinking of a middle ground that actually keeps the EGR functional for the sake of being functional...but reducing its effects on the overall health of the engine.
If the States or Feds couldn't point to the EGR on a diesel pickup...a one-day class, an official illustrated government publication and a hand held diagnostic tool could easily take care of that for inspectors. I fully expect every State to be forced to comply with some MORE regulations in the short term. The way the liberal EPA fifth column is going its just a matter of a couple of more years. Its gonna get nasty for enthusiasts. I'd like to just say "ya..my EGR cooler is there and it is recirculating exhaust gases" while keeping its damage to a controllable level.
I suppose a sniffer test might throw my idea in the trash. But then again...does the Bulletproof cooler perform exactly as the OEM unit did in ALL respects as far as the EPA is concerned? And does the cooler keep the incoming temps of the exhaust gas down to the stock levels or better?
