catalyic converter bypass?

SES light was never on. I knew that the cat was a major problem with the engine problems so i gutted it. my car is running 80% better now, but O2 triggered SES light after 300 miles ( i drive 45 miles to work and 45 miles back). So unless an earlier PCM will work, i will have to buy a new converter. I have gave up on tuners because i cant find access to one with out buying one. I do not know where to find an earlier PCM but found this one at 3800 performance

http://www.3800performance.com/Merc...e=PCM_GT_V1&Category_Code=PCM&Product_Count=2

Would this PCM work? It says something about cat back system so i figured that combining this and the defoulers might work. BTW they just got a new tuning kit in supply for $500.

you have to run the same year PCM IIRC.

That could work.

Just ask them if they have set the rear O2 codes to non-report.
