sort of on topic - is there any problem with teeing your boost gauge into the vacuum line about 5cm from the ecu? slower responsiveness for ecu?
|
When Bruce Bowling was testing the Megasquirt at the beginning of the project, he had 30 feet (9m) of vacuum tubing to see if it affected the response of the ECU. he found that there was little difference in having 2 feet or 30 feet, although the longer it was, the more the pulses pulses were filtered out.
i put a carby fuel filter in series before the ECU, and in my testing, there is less than 0.05 seconds difference (if there is any), as that was the lowest time difference i could datalog.
since the fuel filter is a much much larger volume, it should be no problem
