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.

thanks mate, yeh mine hit 16 psi yesterday after i thought id fixed it :blink: although it didnt feel like it was pushing 16 psi. i got some spark plugs will put them in on sunday. only want to run 10 or 11 psi at the moment too

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

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
