No doubt.. Wish I had the fancy tools, but alas, nowhere to put them even if I did have them

Anybody know why the DPE numbers differ from these slightly if it's the same sensor in a different package?

schpenxel

I thought there were a few versions of the sensor with slightly different equations but could be wrong.

So did everyone settle on the 250/10 then I don't have my stock sensor to play with since that was used for this core. I had 255/10 in it from the past, but it seems high. I need to hook up my compressor and gauge to verify it.

DSteck

DPE's value is what I originally came up with based off of the graph image shown on their website. The problem with that is that it's based on a Vcc of 5.1V, but it actually should be 5V which cleans up the results of the transfer functions.

250/10 is correct.

That's what I'm using and can say with engine off it's dead on and at idle I see the same MAP reading as it was with the stock sensor

So, to me that seems right

And DSteck said so, so there's that

Ya checked em out.. But u know how it goes some sites still up when companies are gone lol

Just so you know you can still run the E38 2.5 bar OS with a MAF and do not have to go SD, but that is an option as well. Your LS2 will gain the extended MAF table with the OS but not a higher injector limit.

just saying that is all giberish too me well bc im not inclined like some of you haha
basically i was told to go to a 2 bar or 2.5 by the tuner.. And I am really looking into e85 as well to replace the meth..

schpenxel

Gotcha, yeah they're still good to order from. There's also a Cobalt 2 bar sensor that is cheaper but I don't know the part number offhand.

UmX

i think i have it saved ends with a 36.. Just concerned i may go past that 15psi with a T trim.

schpenxel

Gotcha, yeah that 2.5 bar is a good option then

UmX

guess they dont answer their emails.. after i placed an order.

DSteck

What did you need to know? It may have just gotten lost in the fray. Apologies if that's the case.

UmX

Was just curious how long ship time was from order date.. So I can plan for a tune date..Placed order on thursday. Thanks.
