I've been wondering if there is a bullet proof way to eliminate the need for a VSS input on the '427 PCM? I've been wondering if by-passing the near idle table of the '427 PCM is practical or possible. The '427 PCM does not have a neutral / park switch input like the older '7747 and similar ECM's. It seems the '427 PCM really needs the VSS input? I did some bench testing and it seemed that setting the maximum speed for near idle tables (MPH & TPS) to Zero's by-passed the near idle tables. I'm thinking the bench test is not as accurate as an actual vehicle. I've been thinking maybe setting the near idle MPH table settings to Zero but leave the TPS setting at the stock setting of about 2.7% might allow using the near idle table and eliminate the need for a VSS? Anyone try this on a vehicle yet?
