Ladybug Posted April 20, 2015 Share Posted April 20, 2015 You should find your ecu pinout here https://www.xcceleration.com/pinouts.htm Open whichever diagram is for your car and check what the location of the boost solenoid wires are on the pinout !!! Use a multimeter to check for continuity by putting one probe in the correct pin on multiplug then put other probe at the boost solenoid plug end ,multimeter should beep if ok and repeat for the other wire on solenoid plug too This should tell you if the wiring from ecu to the solenoid is ok Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted April 21, 2015 Share Posted April 21, 2015 Here's the best pic I've got of the wiring in that area on my v1 Let me know if you need a better pic Quote Link to comment Share on other sites More sharing options...
Ladybug Posted April 21, 2015 Share Posted April 21, 2015 Take it your using a apexi ecu ?? Savage Quote Link to comment Share on other sites More sharing options...
Ladybug Posted April 21, 2015 Share Posted April 21, 2015 Also as temporary measure try looping the pipe from the wastegate actuator straight to the nipple in the turbo compressor intake This will check your turbo is boosting up to wastegate pressure (std boost) Will also help to eliminate were the problem actually is Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted April 21, 2015 Share Posted April 21, 2015 Yeah I'm running apexi with the separate lead to another uprated map sensor (off a my 98 onwards classic) , but the standard map sensor wiring has to still be plugged in even though the oe map sensor vta [emoji15] Quote Link to comment Share on other sites More sharing options...
Ladybug Posted April 21, 2015 Share Posted April 21, 2015 Yeah just spotted the standalone map sensor just helps to know Take it all the settings on the power commander are ok in terms of boost setting etc Been a while since used an apexi tbh Quote Link to comment Share on other sites More sharing options...
Ladybug Posted April 21, 2015 Share Posted April 21, 2015 Have you tried cleaning the boost solenoid aswell as they get bit gummed up over time quick squirt of wd or brake cleaner down both outlets usually helps Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted April 21, 2015 Share Posted April 21, 2015 Yeah it's all been mapped in [emoji6] Just thought I'd remove the oe sensor the other day to neaten up the bay a bit ..... Only boosted to actuated pressure (0.5bar) so I refitted it and I'm back to 1.5 bar again . Have a squint at my v1sti build thread on here if you get bored on your lunch break [emoji4] Quote Link to comment Share on other sites More sharing options...
