Mine is a pro-i ebc 52 mm guage type mounted in my air intake. Not the best, was on a budget when I bpu the car.

 

I had the Depo racing version of that before I got the DET3 from Lyndon and although it was basic it worked ok. Maybe the solenoid/valve has started to fail, if you can find a one way valve try using a bike pump to create a pressure up to the controller and see if it holds it or if it drops off. You will need a one way valve in line though

Whifbitz are in South Wales, that isn't far! :D You should try living up here, 4 hour drive to Whifbitz London, 6 hours to South Whales, and 6-7 hours to SRD :D

 

There are plenty of threads on the VSVs, and diagnosing faults, so you'll be best spending a night on the forum search function. :)

Sorry to hear about your boost problems, I've had a couple myself and for fault finding I myself found it easier to connect a compressor or something else with 1,1 bar to the feed of the vacuum lines. That way you can at least test the sequential valves and solenoids with a 12V source and see how and if they work and if there is a leak in those lines. Hope this makes any sense and helps. For understanding the system, I find the faq here very helpfull, or http://www.max-boost.co.uk/max-boost/supra/boosting_the_beast.htm

 

Btw, what happens in TTC?

Hi Jos , will be putting it into TTC tomorrow to see if it helps, if it boosts OK then I guess it is the vcv valves.

I have been reading up on the system trying to understand, guess I really need to get vacumn pump and start learning to test! Or take it to wiffbitz, but u hate not being able to fix it myself !!!

How about cheering me up band sending pics if the side skirt's you have for me.
