Thank you to EFN (zerotohundred.com - forum) giving the idea. The idea is to get the a better reading for FPR meter reading.
Please do take note this is a setup for Silvertop using MAP Sensor.
Previously the original vacuum line was from D directly connected to the Fuel Pressure Regulator (FPR). The reading on the FPR was flucking, and it’s hard to get a pressure reading. Thanx to EFN’s idea, he changed the vacuum to this current setting.
A "Y" section (Vacumm reading from all 4 throttles)
B connected to E "Y" junction
C to MAP sensor
D is blocked (Vacumm reading from single Throttle)
E "Y" section
D section close-up
E "Y" section
A "Y" section
Wallaah…once completed no more flucking AFR meter…
=====================================
what ecu you using? is standard silvertop ecu how did you do that?

I’ve converted into complete Blacktop wiring harness with MAP, Air Intake Temp, O2 sensor and ECU…just rewiring everthing back up…
Done by mechanic…

Nigel,
No…
this one work with BT ECU which uses MAP sensor…

Is silvertop vacuum diagram application compatible with blacktop engines? Pls let me know asap.
I’m having a problem with my Blacktop engine, when it come to Vacuum setup.
