Question: Isspro

[x MadMAX DIESEL]

Did they go out of business? I remember rumors and they are not answering the phone right now. I was wondering what the difference between there two rail pressure gauges was. Figure its just the harness, but I don't see anything thing on there site about it. PPEs harness will work with all years and I thought they were made by isspro so I'm confused to say the least :rofl:

Got ahold of them. Heres the info. The lb7/lly gauge reads up to 26kph, and the lbz/lmm reads 29kph. Now if only I knew what that meant.

Be aware that some rail pressure gauges are affecting the engine performance.

They use the factory sensor, and if they alter the resistance at all, the engine sees a higher pressure than really exists, and backs down the CP3.

That is normally not a big issue for us, as we can max out all the pressure tables so it will have no effect. But if you are running a handheld or a tune that doesn't max the pressure, you can lose performance.

PS - They are talking about Thousands of PSI (Kilo Pounds). What the "H" is, I don't know.

Since you are looking for rail pressure drop, you don't a gauge that goes any higher, not to mention the factory sensor only reports so high.

So that means that even though both say 30,000 on the face, that neither can actually read that? The lb7 gauge will only read to 26,000 and the lbz will read 29,000?

Max fuel pressure base in efilive is 250, which mine is set well below that. I am not running any "trick" boxes that piggyback into the railpressure sensor now so I think I will be fine as far as them hindering performance

 

[McRat]

Yes, you will be fine with EFILive.

AFAIK, the LB7/LLY will only read 26k from the sensor. The signal bottoms out.

Thanks for the info Pat.

I think Michael Pliska is still working for Isspro, so they must still be in business.

 

[x MadMAX DIESEL]

Yes, they are. I got ahold of them this morning. Might be the same mike, the guy I talked to said I should call back on Wednesday. Said a Mike would be in that could answer some questions alittle better and hes a duramax owner himself.

I don't think Michael Pliska owns a Duramax, but he is the driver of the Dirtymax race truck.
