so i hear a ticking sound form my ECU under boost

why is it doing this?

Ive never had an ECU growl at me lol

You sure its not your engine pinging at you under boost ;) , sounds a lot more logical than an ecu making noises. I can't even begin to think how an ecu could make any noise? :(

Try turning the climate control off and see if it still does the noise.

Over time the fan can become dirty and therefore unbalanced, this will then cause it to "tap" against its housing.

Happend to me about a year ago.

with no AC on, no radio on

its a ticking sound. i had a friend ID where it was comming from while he was in the car one day.

I dont notice a loss of power at all, its just annoying

Yeah detonation (pinging) is a ticking sound (well at least thats how it sounds to me), espically if you say its only doing it under boost. But I mean I could be wrong, it is a car after all and a ticking noise could be anything. But I seriously doubt its the ecu! Anyone else?

CHECK YOUR FRONT DRIVESHAFT UNI'S!!!!!!!!!

Seriously dude, mine did this not long after I bought it, I thought the tapping sound was coming from behind the dash, but the intermittent nature of the noise made it really hard to track. Apparently the front shaft should have next to no play in it so if it has freeplay (as you expect a rear shaft to have) then you need new unijoints.

pinging is not really a ticking noise.

pinging is more of a "two twenty cent pieces being shaken in a closed hand" kind of a sound.

Yeah thats probably a better description....but to some it may sound like a kind of ticking

Hey, did you get this resolved? In another thread, you have lost spark - maybe, i think that problem isn't resolved either..

Is it possible that you had a short in the ecu and the current isn't making it to the spark plug? Try taking the top cover off the ecu and see if you can see sparks when you rev if. Just a suggestion.

well, we have it isolated, its a weak coilpack, and i have 3 on the way from osaka japan.

we actually hooked the pack up to a tester, and it wasnt putting out even or enough voltage.

    • normally i don't like to get involed with these kinds of self promotions stuff, but good on you for living your dream man.
    • Remember our cars are 30+ years old so expect the rubber bits to leak. I'd go around your engine bay with a can of "start ya bastard" or similar and look for leaks. FYI I got my car 10+ years ago with the standard boost restrictor in place, I removed it when I got it and the car never had any issues since (besices a leaking manifold gasket). tl;dr- Look for leaks before proceeding.
    • That SSR is actually the same (or similar) as the Jaycar 100AMP SSR (which I use). They suggest the resistor to stop the SSR turning on when the ECU turns off (I believe). I personally don't use the resistor as I use the 5V output from the ECU to supply power to the SSR. I do however run a flyback diode, the old Haltech documentation was wrong too and didn't specify the fly back, I mentioned it to a few of their staff and they eventually added it in.
    • I did manage to do this without removing the engine or front cross member, but I had the advantage that the exhaust manifold was removed. I am not setup to support the engine from the top or remove it. 1. Loosen the engine mount nuts so they only have a nut of thread. If it is a manual, I think you have to remove the gearbox to engine support brackets. 2. Jack up the engine off the bottom idler mount. Jack it up till the end of the slot and nut on the mount. You need this clearance to get the pan out at the rear of the engine. 3.Break the sealant seal to sump. I found a oil pan separator tool helpful to get it started. 4. The oil pick up can be removed with the gap available.  5. The oil pan can be removed now. 6. Before assembling, do not apply sealant to the oil pick up area as your hand will rub it all off but apply to the other three and a bit sides. 7. It is a two man job to put the oil pan back, with the sealant, as you do not want it to touch anything and rub off. 8. With one person supporting the oil pan the other can fit the oil pickup 9. Apply the remaining sealant. This would be more difficult with the manifold or turbo in place, but I think it could be done. As you can see my sealant is a bit ugly, but good enough to seal. 10. Lift the sump up to the engine and bolt it on. We found it was easier to use two long guide bolts at each end to get it nice and aligned without touching.
    • I find building an exhaust a really satisfying job! Looks nice!   Did you consider using an oval pipe to get the same cross sectional area but keep it above the chassis rail?
