• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

strange problem

ok so I'm not sure what the exact name of it is but the guage on my dash that displays mpg,boost,oil life etc is acting up. When I start the car everything reads 0.0 or just 0. As soon as I put it in D and move the car, everything flash's 0 or 0.0. It did it one day then was normal the next, then a few days later acted up again and has done it ever since, anyone know what's goin on here? Oh and it no longer indicates how much boost its getting. Car runs fine other then this, no side effects...
 


still have this problem, anyone ever had this and fix it? The other day I left to go somewhere and it started working again, shut the car off later and it's been flashing again ever since. This is driving me crazy!
 
just putting this out there,i dont know if this can work, but if there is a fuse maybe try and replace that

As far as I know it was stock. I replaced it with a ZZP 1.0 pcm. Everything works great now. Old pcm got some water and corrosion in it somehow. Bad seal I think.
