LEPORE Posted April 1, 2009 Report Share Posted April 1, 2009 why is there such a big price gap between these map sensors besides paying for the name brand? is there any difference other than the price? i have seen them as low as $50 on ebay.. http://store.summitracing.com/egnsearch.as...sensor&x=26 Link to comment Share on other sites More sharing options...

StarquestRescue Posted April 1, 2009 Report Share Posted April 1, 2009 (edited) I just bought this one. $64 + $8.75 shipping and insurance. Had it in about 2 days. http://www.diyautotune.com/catalog/map-bar...nsor-p-161.html I know it gives different voltage out put than my hks sensor did at vacuum and zero vac. I did not test it at pressure. Since you have a gm maybe stick with a gm sensor, than the voltage out put curve should be the same.

scott87star Posted April 1, 2009 Report Share Posted April 1, 2009 Digikey. You can order just one for $14.36. It is a different package but if you do some research you'll find the exact part, all manufactured by Freescale Semiconductor. Scott Link to comment Share on other sites More sharing options...
