Blah...anyone other Defi gauge users/owners want to chime in with their experiences on how their gauges read?

 

My Defi seems to read the same as my Blitz DTT DCII which has a electronic boost gauge.

 

my defi d was off by 1.5 also (becuase when off it read 1.5 instead of 0)

my autometer is accurate (tested against other gauges assumed to be accurate)

 

And how does THAT read??????

 

I'm assuming you're speaking in psi. When my car is off I read exactly 0, so this isn't the problem. It's only under high boost that I suspect either spiking, gauge inaccuracy, or a combination of both factors.

 

I just noticed today my defi d psi gauge, bought 3 weeks ago, reads a little under 0, half between 0 and the next tick when car is off. I also noticed my mitsu gauge needle is under 0 as well. Im kinda pissed at myself for not noticing the mitsu gauge earlier. Anyways, when reading my defi d gauge, should I just go with where the needle is at, which is 21psi, or should I substract whatever number its at when the gauge is off? If I do that, then I assume my boost spikes to 20.* psi's.

 

Don't know if my guage is accurate or not, but it read exactly what a stock EVO is supposed to read for stock boost. Hit 19ish psi and fell to around 15ish at redline.

 

My Defi D reads about 1 psi higher than my Blitz electronic boost controller. Don't know which is right.

 

Bump

 

The defi link and the evc read exactly the same on my car. The defi reads differently then the EMS but that is expected(differential and absolute pressure). Remember the Defi D and the Link are 2 different guages. Ive have heard of inaccuracies of the D series in the past.

 

I guess I'll try contacting defi and see what they say about the needle not resting at 0 and the accuracy with that problem.

 

Hmmm.. well this kinda sucks. I was planning to buy a D-Series boost gauge to match the EGT gauge I just got. If it has inaccuracies like that... I will just stick to the small mechanical HKS boost gauge I have. For the price difference... Autometer might be a better buy, at least some of their high end ones.

Definitely bump this up for more info.

 

I've got the defi-D gauge and it ran the exact numbers that stock where suppostue be, i've turned the boost up now.

 

Im running my xede stage 0+downpipe and Im not hitting 21psi with this gauge. It could be accurate but then again I have some doubts. Im going to tap my zt-2 wideband boost sensor to a different location and check the boost before making any changes to my xede map. I did send an email to defi, so I'll keep everyone posted if your having the same prob

 

I have a defi amber bf and it reads 0 when off... max at around 1.45 bar and tapers to 1.15 bar and my car is bone stock.
