ISSPRO oil press guage

[Tapage]

I know I'm not the only one here that love the ISSPRO gauges looks and performance .. but I'm a bit disapointed right now ..

Was 2008 when I decided the ISSPRO route and back in 2008 after a few weeks with the gauges working my oil press gauge did ( 2 or 3 times ) weird jumps one seg reg normal oil press next seg 0 PSI, next seg 100 PSI and then back to the normal oil press ..

As I said it happen 2 or 3 times most when Marilu was cold .. I thought 2009 it happen again few times I never worried to much. I drop a mail back in 2008 to the vendor ( Diesel Manor ) and David Murphy said, was a bad ground ..

I really take care of my isntalation ( as usual I ake care of all my Cruiser stuff that I done by my self )

in my isntalation I share grounds and V and the oil press it's the only that have problems ..

Last sunday I start my engine and the gauge don't work at all .. I shut off check oil level, conections and most obiusly things ... then call a friend that have a mech oil press gauge, and we use to see that there is no oil press problem .. just the gauge..

So after that long story it's anyone had similar problems or have ohms values at the sender to check if here is the problem .. ?

Last I drop a mail to ISSPRO and the vendor without reply by now ..

thanks !

David

i have heard of trans temp gauges messing up by isspro
i hope my don't s*** the bed

If I'm reading your post correctly, your oil pressure gauge is an electronic gauge as opposed to a mechanical one...so you have a sender unit that sends an electrical signal to your gauge.

If that's so, then it's a similar system to their Pyrometer that I'm using. Sheldon and I have the exact same ones, bought at the same time, and his is on the fritz also. Sometimes it will give him really weird EGT readings and he has figured out that by putting a little pressure on the sender module, it goes back to normal. It's almost like there is something cracked or loose inside, that makes a connection when pressure is put on it. So if it's mounted in an area that allows it to move or flex, then more resistance may be encountered when it shifts.

I'm guessing something is wrong with your sender unit...

thanks folks .. and yes it's a sender at the engine bay and signal to the module that send it to the " gauge "

I was unable to reach someone at the ISSPRO tech support .. ( anyone ver try call 'em ? ) but I got a trouble shooting guide that drive me in some test at the sender, module and gauge .. that I will do ..

My module it's under my center console .. so a bit complicated to reach wouout pulling the console but I will give a try to the pressure technique to see what happen ..

Honestly I was expecting 0 failure form ISSPRO .. and I feeling disapointed now ..

 

[Stone]

Yeah...I wonder how many others have had any issues with their electronic gauges? So far the two I've had have been good...but that's hardly a significant sample size.

 

[ForealBoreal]

I hope mine turn out good....
I am waiting for my fittings and then I will throw mine in.
I have an electric egt and trans gauge..... Hopefully i won't get duds.
I hate ripping apart my 81s dash its a real pita

It is ..

Update: yesterday I hear back from the ISSPRO customer tech support and got a number .. wasen't able to reach the person ( Don ) @ 503.528.3402

And other valuable info it's the trouble shooting pdf .. if someone want it, just drop me mail to tapage at 4x4panama dot com .. ( dot = . ) I wil be more than happy to share it ..

Since they are in Portland ( I guess ) I will need to wait a couple of hours before try to call Don again .. anycase I will perform more test this weekend ..

I have seen occasional bad solder joints in the amplifier box on these series of gauges, and that is the likely issue on the case mentioned above where pressing on the box causes it to work. Give us a call, we'll make sure you are taken care of.

I strongly recommend the EV2 series of gauges over the EV series mentioned in this thread. They do not use the separate amplifier boxes, are a much more modern design, and are made right here in Portland (the EV series was contract manufactured offshore). Aside from the boost gauges (where we use an electronic gauge for EV2 and mechanical for EV), the pricing is not much higher than the EV series.

Thanks Michael .. I appreciate it ( and sure others too ) .. I already contact ( after few days ) with Vidara and Don .. who put me in contact with Robert .. that finally said it should be a bad oil press sender ..

Right now I' waiting a new oil press sender .. after few tests at the oil press sender looks it's the problem.

It just go to 0 ohms if it get oil press .. no matter what rpm range I put the engine ..

With the engine off it start at 18 ohms and raise up to 154ohms and then back to 18 ohms and again ..

I hope you release the EV2 sooner .. I won't trash 500 bucks in gauges .. just to have a integrated gauge without the external module box ..

I'm sure are nice .. but not to me right now ..

Is this really the case...and if so, I guess we're being ripped off in Canada, because when I priced out my gauges late last year, I was really interested in the EV2 but couldn't justify the huge price difference between the EV and EV2.

Bought mine from PDR, and these are actually the second set of ISSPRO EV gauges that I've bought as the first set went into the BJ74.

BTW...I think it's a pretty nice thing for you to post and make sure Tapage is getting taken care of. That says a lot about the integrity of your company.

 

[Tapage]

Which it's the real price difference between EV and EV2 .? ( I'm not considering buy another set .. but it's always good to know .. )

 

[cruiser_guy]

I've got the Isspro gauges in both the '55 and the '60. The '60 just has the pyrometer and boost gauges, the '55 has the pyrometer, boost, volts and tachometer. Zero problems so far.

I have gauges for the '45LV as well but they are not installed yet.

I think the most attractive difference to me was the intagrated circuitry inside the gauge with no external amplifier box as Michael had already mentioned. The LED lighting was kind of cool, but not really a big deal. As for the price difference, I can't remember exactly, but I vaguely recall a figure over $100 difference. Tried to call PDR to get another quote, but got sick of being on hold.

Here's the features on the EV2:

Just released, the new EV2 series of gauges from ISSPRO.
• All are microprocessor controlled stepper motor driven for the utmost in accuracy.
• No amplifier boxes - just one simple wiring connector on the back of each gauge.
• All gauges utilize a weatherpack connector for their sensors.
• All gauges feature a full 270 degree needle sweep.
• Fuel pressure gauges utilize a robust electric sensor selected specifically for diesel applications. No isolator is needed. Just Plug and Play.
• Each gauges uses LED lighting. Pointers also illuminate.
• Separate dimmer in R-72022 wiring harness allows for calibration of illumination with factory instruments. Gauges will dim with the adjustment of your factory dimmer, but this separate dimmer allows for fine tuning to match brightness.
• Largest selection of different gauges.
• Assembled in the USA!!!

I notice that it states "assembled" in the USA, not "made" in the USA. So does this mean that there are still offshore components in the gauges and they are just assembled in the USA instead of the whole thing being made offshore? I still think that overall the quality is very good...and I wouldn't hesitate to buy another set. The EV gauges have a much easier to read face compared to something like the Autometer. And I prefer the analog compared to digital.

A little off topic, but I must say I am impressed when a representative from a company is willing to post on a forum to help resolve issues.

Actually 100 bucks it's a bunch of diference .. at least to me ..

When I was triying to get info in my issue it takes time until I can reach Don at ISSPRO to get answers .. actually was Vidara @ ISSPRO that take my call and her time to locate don and trasnsfer my call whith him .. then him finally put me in contact with Bob .. ( long chain .. )

I will take my oil press sender as a fortuitous case .. but I never have any issue with my old VOD gauges .. taking in mind that they are under worse conditions in Tencha ..

Autometer have a new GS line that it's pretty cool .. actually a good friend here have a set and are really cool .. ( no aditional boxes ) he was laughing on me due to my oil press sender failure ..

 

[Tapage]

here are ..

nice uhh .. ?

complete line ..

Auto Meter GS Gauges

Just to update this thread .. I got a sender replacement from ISSPRO 35 bucks .. and it solve all the issues .

Good to hear, Tapage.

It also reflects well on a company when their guys are willing to help to this extent when one of their products needs repair.

Oh great.. This probably explains why my EV series Pyrometer reads 1500deg most of the time.
Of course it has to happen to the most invasive install I have done yet..
in the vents. Can't wait to rip the dash apart again.
Thanks for posting on the thread.
