Fulcrum2000 Posted October 16, 2020 Share Posted October 16, 2020 Hi All I am at the final stages of BPU now and after many problems I just need help with my boost controller. I have a Gizzmo V4 OLED installed but after having all the vacuum lines put back to stock I need to know how you install them to the two turbos can anyone please help? I've been trying to get this car safely up to BPU for 3 and a half years and still not managed. My new mechanic says he needs a diagram or description of how to attach them as the two turbos are connected it is not clear, so can anyone please tell me how you get the Gizzmo to work up to 1.2bar total BPU? I thought it would be a case of just connecting it to the second turbo but he says as some of the pressure goes from the first turbo to the second that isnt the case. Does anyone know exactly what vacuum lines go where? As I say everything is now stock vacuum wise but all other elements (restrictor ring FCD etc etc) are installed. I've looked all over Google and there's nothing. Quote Link to comment Share on other sites More sharing options...
Fulcrum2000 Posted October 16, 2020 Author Share Posted October 16, 2020 Just to clarify the vaccum lines are stock, and the Gizzmo has power but is as yet only waiting on the correct vacuum layout, any help would be much appreciated Quote Link to comment Share on other sites More sharing options...

If I have to buy an HKS I will but I just assumed as most instructional threads on attaining BPU dont mention you need exclusively an HKS BC it must be possible with any competent BC to achieve the same? Does anyone have a gizzmo running BPU? Thanks in advance for any help I have my car at a garage waiting for advice Quote Link to comment Share on other sites More sharing options...
Scooter Posted October 16, 2020 Share Posted October 16, 2020 Is it worth a call to Horsham developments............I'd never heard of a Gizzmo controller before to be honest but they might be able to advise? What boost do you get at present? The restrictor ring could/should be ground out to the minimum boost you'll ever want (1.0bar?) then a controller to up it from there.

I'm getting just under 1 bar on restrictor - removed all the non conventional vacuum lines etc and am just trying to get the 1.2 through the Gizzmo but cant find anything anywhere to even begin to line it up - Have I missed something here, does everyone who goes BPU with twins use a HKS? If so I can go back to this but its the first time it's come up so I am a bit baffled, I thought any good EBC would be fine? Quote Link to comment Share on other sites More sharing options...
Rob W Posted October 17, 2020 Share Posted October 17, 2020 (edited) Maybe looking at the old Blitz Boost Controller installation guide might help you. It’s a 2-port boost controller, I used to have the Blitz SBC-ID Spec R fitted for years before I changed to the HKS EVC 6-IR. https://web.archive.org/web/20050327033044/http://www.mkiv.com/techarticles/blitz_dsbc/index.html Edited October 17, 2020 by Rob W (see edit history) Quote Link to comment Share on other sites More sharing options...

Just out of interest am I the only Supra owner out there whose installed a Gizzmo then? That was a spot of bad luck for me if so! Quote Link to comment Share on other sites More sharing options...
