Zener Diode Mod to MAP sensor signal
Does anyone know about this method of tricking the ecu into not reading boost or lowering the voltage? Also is our sensors a 1 bar or 2 bar? I just found out about and curious to try it so fill me in on ur opinions and info. THANX

The stock MAP sensor on Civics is rated at 1 BAR.

Re:Zener Diode Mod to MAP sensor signal
What you're reffering to has been done many times before...It's just a Map hack...
Trailor park hack, AFC hack stuff...
It's ok, but if you got a SiR I wouldn't do it...you have the cash for an SiR and you're doing a hack?? just sad....it's risky and not reliable

You got to remember that our atmosphere is 1 bar or 1.1 bar already... you got to deduct that from the map sensor range...
