Blitz SBC iD: dual solenoid faulty? - 24/09/2014 12:35
I have had an old Blitz Dual Solenoid SBC fitted for a couple of years now and it has been 100% reliable. I have set it up with 4 different settings from mild to wild and it works perfectly. Being an old model it has the two wire dual solenoid and only allows one level of gain across the 4 channels although the boost 'set' is variable.
Recently had a chance to get a second hand Blitz SBC iD which has the meter/display and the ability to have variable gain and set on each channel.
I fitted it over the weekend and as I had previously fitted the old one it didn't take too long. All the hoses are tight and the electrical connections fine too. However, dispite having set it up with 4 different settings (similar to the old unit), the boost and rate of boost are the same whichever channel I'm on or indeed if I turn it to 'off'!
I get to 0.95 bar boost with every channel and every gear ( base boost). I know I have the hoses on the right way round as they were that way round on the old unit. I therefore think that the solenoid unit is not working!
I can take it apart but how and what do I test? I can't substitute it for the old solenoid which does work as that is a two wire type and the iD has a three wire loom. The solenoid is obviously the key component and very expensive to replace. Any ideas?
