im in a 3 bar os in my dd truck too rodney. dont be skeered!

 

Regarding scaling: if the os matches the sensor type you are using, then you should be pretty close.
You can always tweak the scaler by comparing readings (with key on, motor off) between sensor and actual baro pressure. With key off, they should match

 

I meant: with key on, motor off, readings should match.

it stops at 198 cause thats where the 2 bar stops reading..
Text me this evening, ill get my laptop and get you some table numbers.




Ive got him setup on a 12212156 OS with COS3 0202003
NO Maf at all.

 

i got a 2.5 map s off a guy on tech that makes them. he sends data too for your tune. i would steer clear of 3 bar unless you absoloutly need it THE RESOLUTION IS HORRIBLE ! btw my 2.5 bar map has read up to 22.7 psi for me so far .

 

I'm liking this 2.5 talk, can you post up details on your talk source, part number for 2.5 sensor. Also, will I need to burn two credits on hptuners for this?

 

DSteck on HPT forum makes them. There's another guy, his forum name is C5dude or something, he also makes them.

 

Even though the resolution is worse with a 3bar, unless you cam and tune are retarded, fuel requirements are fairly linear with manifold pressure. Basically, the lack of resolution is not an issue. This obvious does not apply on extreme setups, but I have yet to see one I would call extreme on this forum.

 

Did anyone try the Dmax map sensor. I think it's 3.3 bar map.

I ordered one from Amazon.

 

Im interested in a 2.5 bar or 3 bar setup as well but I don't think my VCm will allow anything but 2 bar. Is that correct?
