Ebc Boost Issues

Hello,

I just installed a HDI electronic boost controller for my r32 GTST but am having issues with it.

When on boost (5k rpm) the car will cut out and make loud sounds from the exhaust. (misfire?)

The EBC was installed by an auto electrician so hopefully we can eliminate a wiring issue.

Before I installed the EBC the car was fine, boosting to correct levels.

I've attempted to change the setup back to normal. Leaving the EBC in the car but bypassing the EBC solenoid which initially fixed the problems but since has stopped working properly.

What could the issue be? Spark plugs?

I've searched the forums but can't find a matching issue to mine.

(brb flame proof suit)

you havnt mentioned how much boost you were/are running.

do you have a boost gauge?

are you sure theres no adjustments on the EBC?

and that it makes exactly actuator pressure before it bleeds any air off?

my moneys on its making more boost and your going R&R or too lean @ 5k rpm

also just one of those misfires etc when you first had the EBC on, would've fouled your spark plugs, now they are struggling to fire.

so new plugs as Nismoid said, then see how ya go...

yeh thats what i was thinking, with the fouled plugs. well now it should be running stock boost cos i set it up bypassing the ebc's solenoid, when i had the ebc on the boost kept going up rapidly even tho it was on the lowest setting, it hit 14 at one stage

I also have a HDI EBC-R, i havn't had an issue with it yet. As the guys have said, more boost requires more spark etc i would change plugs and if you can't afford new coils, get some industrial grade silicone and glue them up not a total fix but will fix most probs (unless coil completely gone). Also get out on a QUIET road or more safer a dyno and get it tuned and set right, if it's boosting to 14psi when it's not ment to check all hoses at the soleniod. This was happening to me but mine hit about 16psi (Shyte), i found that one of the hoses has a slight split. If you set boost to high you may break something. (BOOM) show me the money.

spark plugs fixed the misfire, but the boost controller just doesnt control the boost, it pushes past 16 psi!

runs fine if i use the same hoses but instead of going into the solenoid i just put them back into each other like an extended version of how they are normally set up, runs 11 - 12 psi though

      Purchased a NC MX5 a while ago Basic suspension mods done, BC coils and Whiteline sway bars  New DBA calipers, discs and pads Added some 17 x 8 Konig Decagrams with 215/45 17 PS5's Added some typical NA bolt on's, i.e. full exhaust and intake  Added 0.5ltrs with a MZR2.5 swap, nice bump in torques  Found a detachable hard top which is locked in for a colour match with my local paint shop in Feb 25, this also includes some PDR as it has received a few love taps from parking in the local shops when in the hands of my Minister for War and Finances, me, I park nowhere near other cars and typically park on the street The little thing is awesome, I drive it everywhere, it handles like a dream whether I'm up it or just cruising  But now,  because I'm a idiot, I keep looking at turbo kits....... did I mention I'm a idiot Why is dose so appealing  All of the NA 2.5 glory, well.......until sometime in 2025 anyway....🤪

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      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.

      A sporty manual RWD coupe with a IL4 Honda engine would only be a good thing I assume we won't see anything released for a few years though, unless informal talks and designs have been going on for a few years,  and due to the current, and future, emmisions and safety requirements, I assume anything "sporty" they would do would be at least some hybrid thingie And hopefully anything they are thinking of has nice lines, without lots of plastic and fake bits hanging off it like that horrendous FK8 that looked like it was designed by a 13 year old The other issue of course in the current market is cost, currently the type R is around $70k, a twin is around $50k Meh, I'm old and grumpy and would rather buy a older model car and waste my coin on that than buying anything currently available new
