Split Second Voltage Clamp
 

ok, i am using an adjustable voltage clamp from Split Second to clamp the signal on my map sensor. currently, it is set at 2.95 volts. when i hit boost in the upper RPM's, the car still goes in to limp mode. does anyone know if 2.95V is too high or too low? what should i be setting the voltage clamp to?

I am running a P61 ecu right now, and i've also tried a P72. the same occurs with both ecu's.

any help would be appreciated.

Uberdata is your friend...

no offense but, i' just trying to find info on this particular voltage clamp, not another method.

how much boost??
at about 10 psi is tha max with a hack...some people are able to go to 12 psi some to 15, but it's not safe.
Depends on the map sensor and ecu i guess.
but if you passed 10 psi..be happy

well...then wouldnt it make sense to try one at a lower voltage? why dont you do the work and let us know :-\

i just broke in the engine and i'm attempting to just tune it with the wastegate controlled setting of 7 psi.

it most definitely would make sense to try a lower voltage. i was hoping someone who may have done this before would know the correct voltage level that worked for them. i will do the work and let everyone know.

the cel will trigger when the map sees over a tad bit over 3.0volts, My brother made a VC and had it set at 2.9ish volts and it never came on.

thank you. i will double check where i have the voltage clamped at and let everyone know.
