Running 18lbs on stock map sensor
It's wierd, I can run 18lbs of boost without any problems on my stock Honda map sensor. I heard after 11lbs it does something??

Re:Running 18lbs on stock map sensor
what management do you have?
are you running check valves or a missing link? |
Re:Running 18lbs on stock map sensor
No check valves or anything, running the ZDYNE GOLD SECU w/ the B16FI program

Re:Running 18lbs on stock map sensor
After 11psi, it's not increasing voltage. Which means your ECU doesn't know you're higher than ~10psi.
I don't know the physical limit of the stock MAP sensor before the diaphram rips. |
Re:Running 18lbs on stock map sensor
So you mean if I boost past 10lbs on the stock map my Ecu will only provide enough fuel for 10lbs worth of boost even though I am at 18?

Re:Running 18lbs on stock map sensor
No... I mean that the ECU will not know you're running more than 10psi.
Basically, it will use the last pressure column as a "catch all". Whatever fuel and ignition values you have in the last column are the same values that will be used for anything over ~10psi. Same goes with RPMs.. any values you have in 7400rpms are the same values that will be used when you rev PASSED 7400rpms. |
Re:Running 18lbs on stock map sensor
The actual sensor itself can suffer damage when you're running around 13 psi repeatedly. You need to hit it with a check valve.
Also, just curious, what size fuel injectors are you running? |
Re:Running 18lbs on stock map sensor
I was able to run about 22 psi (on accident when I ------- forgot to reattach the wastegate actuator vacuum) with the AFC hack, and although I got a little bit of detonation the enigne took it. The detonation only occured when the boost first hit then I think the water injection shut it up. So its pretty risky ass ---- :)

Re:Running 18lbs on stock map sensor
watching my voltage of the map sensor @ around 10.something psi the voltage will peak but my boost will go up 2-3 more psi. I run the turboedit rom in my pm6 and i guess it doesn't have the MAP sensor CEL code in there anymore. or it has been modified to not be totally ------- retarded like the stock honda map CEL's >:(

Re:Running 18lbs on stock map sensor
heh.. Dave Blundell wrote a very nice boost routine so that the ROM used with TurboEDIT will not "Freak out" when it see positive manifold pressure.
