hey hey

i got a hdi electronic boost controller with a boost guage n had it installed, after that was having issues with misfire and other things.

i then wired it up so i bypassed the boost controllers solenoid i thought this would run stock boost but now its running 12.5 which is way too high considering its on lowest setting.

any idea as to why its running so high?

In the thread below SKYPER says that he has tested a few R32 wastegate actuators and they were higher then 10psi, they varied around 12psi.

Plus a full exhaust so 12.5psi sounds ok. As Hypergear said remove the boost controller from the system and see what just the wastgate actuator runs at.

well i got my spark plugs changed and the car is running well when im not using the boost controllers solenoid, still around 12 but i can deal with that for now. as soon as i put the vacuum hoses to go through the ebc's solenoid and take it for a drive the boost shot up to like 16 psi and was going to keep going untill i took my foot off the accelerator.

im 99% sure its wired up correctly, the ebc is a hdi sbc d or something, the one that comes with the really bright boost gauge, also if the key is turned on the acc should the boost guage be reading a number? if so what number, thanks

Good work. So as you have probably worked out the wastegate actuator on your car operates at 12psi. This is a minimum boost pressure so you cant go below it.

When you introduce the boost solenoid it spikes to 16psi and above, so your boost controller is not setup correctly.

Sorry I cant help with that specific boost controller.

haha thanks, i was told it was 10 by a few people so i was a bit confused :P

ive tried everyway the boost controller can be set up, looks like ill have to spend some more time trying to figure it out, serves me right for not going for the profec

    • I would not be surprised if you are the only person on earth that has the interest/desire to do that lol.  The Haltech base map is a really good starting point, the car will fire easily and drive very well, even on mild boost levels. To me, following your advice sounds like some sort of ancient Chinese water torcher lol (this is not an insult Josh, never change <3)
    • Those car show concepts from the 2000's and 2010's like the Floria and IDx were brilliant and should've gone ahead, at least one of them. But neither Honda nor Nissan are thinking about affordable performance any more, which is truly sad.  Even if Toyota's liquid hydrogen ICE development reaches the point where it's commercially viable and the infrastructure to support it, Honda/Nissan would have to wait until Toyota allow fee access to their patents to offer it with any smaller performance models they released to take advantage of it.
