I got in my car tonight while I was out and noticed my boost gauge was pegged past 2.0 kg/cm (all the way off into the GReddy emblem). I turned my car off and back on again and nothing moved, just stayed there. When I began to drive and hit slight boost again, it began working again OK. I have a GReddy 52mm Electronic Boost Gauge, stock boost with no boost controllers. Everything has been working fine up to this point. Kinda of scared me that I hit some sort of boost spike, but if that was the case wouldn't the ECU shut the boost down or register a CEL? Has this happened to anyone else? Was this a fluke thing and it registered some sort of anomally? Thoughts guys?

I would say a boost guage problem, if you had a boost control problem like that you would have hit fuel cut.

with any electronic gauges, from my experience, there is a lot more potential for problems. stepping motors, electronic sensors... all have a potential to lead to problems when they are basically attempting to perform a simple operation like measure boost, EGT, Oil pressure.

I have never ever had a problem with a mechanical gauge. They are simple, and they perform their function as they should. typically with no headaches or issues.

Did you make sure you installed the little oriface in the input line of the fuel reg boost line? I have the same gauge and never noticed a problem like that.

I did not install the orifice, because it was not jittering, but I will try it if it happens again. My buddy who works alot with GReddy indicated the same thing that FourDoor said....probably a fluke thing and the fuel cut would of kicked in. I would of definitely known if it had spiked that bad.

Thanks for the replies guys.

Bump....well it appears to be a fluke thing, did not reoccur. Knock on Plastic

I promise this is my last post on this subject, but I found the cause. It appears that GReddy Gauges do a calibration cycle for just a sec when you power it up. If I immediately turn the ignition all the way to the start position without pausing first in the on position, then it pegs, then it resets once it receives a signal from the boost sensor. If I wait just a sec I avoid the problem. This is better for everything as well, lets the fuel pump prime. Anyway...issue resolved. FYI
