TP vac reading $59

[mjaugus]

Vacuum reads low(4.95-5.55Hg)at idle in tunerpro.Guage at map and fpr reads 16Hg.Reset the ecm and TP will read correctly,but only until restart.Checked grounds and ecm connections,replaced 3 bar map.I've messed with every wire there is during the last year,so I figure its something I did.Anyone run into anything like this?

do you have a 3bar map on there?

We updated some of the Baro Code that reads that atmospheric pressure. It makes an adjustment to the MAP. It could be a problem in that code or it is a problem with the ADS file I made for $59. I would post over on code59.org so Dig and others can respond.

Will do.Wasn't sure if the problem was related to 59.

All is well.Start tp after engine is running and it reads correct!
