Re: My SRP (Stealth Race Pipe) \'How to\'
I have a 2003 ALH wagon. If I were to either plug the vacum line or make an SRP, in conjunction with the EGR VAG-COM mod, would I throw a CEL for sure? Could any mod be done to cure this? I have heard that a company can reprogram the ECU to completely turn off the EGR, but I want to keep this a reversible mod so that when low sulfur fuel arrives I can start being enviro friendly again.
Also, on the topic of block off plates and SRPs, would it be wise to block off the exhaust before the cooler and fully remove the cooler? The coolant lines could be either linked to each other or capped at their sources, no?
I have never dealt with a VAG-COM, but plan on getting one soon. For someone with experience, could the EGR parameter be limited to a very narrow range and then the MAF be essentially calibrated so that the discrepency caused by disabling the EGR would cancel out. If it works the way I am picturing, the EGR would be set to always deliver one ammount of volume, and at the same time, the MAF would be "calibrated" so that instead of now reporting the full volume of air entering the engine, it would report that volume minus the set volume that the computer thinks is entering though the EGR.
Again, this is only a theory, and as far as the extremities and dynamics of such a relationship, I have no idea. I don't even know if that could be achieved with the MAF with only a VAG-COM, but it would be sweet. We could just use golf tees and a 5 minute code fix to cure the soot problem forever.
