Re: Harnalien's Build Thread
Yup. The PCM likes to see a 40 pulse per driveshaft revolution (PPR) VSS signal w/ autos and 17 PPR on manuals. This is mandatory if running a computer controlled trans. Drive by wire throttle would likely be highly affected as well.
For a 700r4 and cable throttle body, I've seen guys get away with using the Dakota Digital SEN-01-4160. It's output is not even close to the stock 40PPR count, at 8 pulses per speedo cable revolution, but is enough to let the PCM know whether you're stopped or moving, setting the appropriate idle tables, and ending the goofy surging/stalling issues. It would also allow you to keep your cable driven speedo, if so equipped. Though I haven't tried this personally, it is all fairly well documented over on LS1tech's conversions and hybrids forum. One could spend a lifetime over there learning... Edit for linky: http://www.dakotadigital.com/index.c...rod/prd109.htm
