Map sensor
I'm running a s300 (p28) on a cx civic with a H22 with complete revhard turbo set-up, 750 injectors, AEM wideband o2 sensor (for tuning) using stock single wire o2 sensor for ECU. walbro 255lph fuel pump, 3 bar map sensor. everytime I run the 1/4 I can go thru all the gears fine and once I start to decelerate I get a MAP sensor code. I wired the MAP sensor directly to the ECU, thinking there could be something wrong in the wiring but the same thing happens. I did several datalogs and all of them appear the same and far as boost is concerned, no spikes, using gear dependent boost max of 16 psi. The MAP also reads vacum and boost perfectly, shows same as mechanical guage. I even switched MAP sensors and ECU to a known working one. Im stumped please help?
