Hey guys

I am starting to shop around for a new ECu for my car and have been trying to really nut out what would be better for me and what I want. To be honest I'm tossing between the Wolf 3d plug and play and the well tested Power FC.

I realise some of the differet features that they have (rotational idle - launch control) and they all seam really good... But my main concern is Pinging/knock detection. I realise that the Power fc will detect knock but do nothing about it accept tell you that it is going on.

Question is.. what does the Wolf 3d have or do to tell you what is going on?

Hi riceline, firstly let me say I personally like the PFC because it warns you that there is a detonation problem by flashing the dashboard warning light. I would much rather it do that than say retard the ignition, dump some fuel in and cover up for the fact that there is a problem. All I know is, suddenly the car doesn't go very well, but I have no idea when it started or why!

Secondly, what is it that causes the detonation that I need to protect the engine from? If the ignition timing is too far advanced, then cutting the ignition is a bit of a drastic way to fix it. Plus it doesn’t really FIX IT, it simply masks the problem. Same for lean A/F ratios etc etc.

Personally I think there is a better way, by setting up the maps for engine temp and boost you can “protect the engine” and still have the warning. For example, if the detonation would have been caused by too high engine water temp, such as experienced on a very hot day. What I would do is set up the maps so that when the PFC encounters high water temp it adds enough fuel to prevent detonation. Plus the extra fuel helps lower the combustion temperature which may well stop the overheating. You could do the same for excessively high inlet temperature (on a GTR) or oil temp or low fuel pressure or low water pressure (using the analogue channels of a Datalogit system). If you measure the fuel pressure at the fuel rail, then that covers things like blocked fuel filters or failing fuel pumps. Similarly low water pressure covers busted radiator hoses, hole in the radiator, air in cooling system etc.

I can see these things on the Datalog, I know that the engine isn’t running well from 1.15 pm today due to low water pressure. Plus the dashboard warning light flashed at the time and I could back off, or better still, stop and fill up the radiator.

I am not saying that I can’t do this sort of stuff with a Wolf, or other ECU’s for that matter. What I am saying is, personally, I would much rather have a warning light and some mapped protection, than an ECU that simply covers up the problem or worse still goes into limp home mode at the first unusual occurrence.

Hope that makes sense. :)

Steve while this thread has your attention, do you have the wiring diagram for the R33 auto ecu? I have read in your other posts to get the gearchange working properly i have to tap into the TPS and tacho signals of the auto ecu? I just want to confirm if this is all thats needed?

Cheers

Matt

      Did tie rods. Steering now not "springing" back.

      Yep, there's a very minor drift left that happens a few seconds after letting go of the steering wheel, but not enough to bother me. Enjoying the car still!

      Steps to DIY sanding car back ready for respray....

      Sounds good.  I don't 100% understand what your getting at here. When you say, "I keep seeing YouTube videos where people have new paint and primer land on the old clearcoat that isn't even dulled down" do you mean this - there is a panel with factory paint, without any prep work, they paint the entire panel with primer, then colour then clear?  If that's what you mean, sure it will "stick" for a year, 2 years, maybe 3 years? Who knows. But at some stage it will flake off and when it does it's going to come off in huge chunks and look horrific.  Of course read your technical data sheet for your paint, but generally speaking, you can apply primer to a scuffed/prepped clear coat. Generally speaking, I wouldn't do this. I would scuff/prep the clear and then lay colour then clear. Adding the primer to these steps just adds cost and time. It will stick to the clear coat provided it has been appropriately scuffed/prepped first.  When you say, "but the new paint is landing on the old clearcoat" I am imagining someone not masking up the car and just letting overspray go wherever it wants. Surely this isn't what you mean?  So I'll assume the following scenario - there is a small scratch. The person manages to somehow fill the scratch and now has a perfectly flat surface. They then spray colour and clear over this small masked off section of the car. Is this what you mean? If this is the case, yes the new paint will eventually flake off in X number of years time.  The easy solution is to scuff/prep all of the paint that hasn't been masked off in the repair area then lay the paint.  So you want to prep the surface, lay primer, then lay filler, then lay primer, then colour, then clear?  Life seems so much simpler if you prep, fill, primer, colour then clear.  There are very few reasons to go to bare metal. Chasing rust is a good example of why you'd go to bare metal.  A simple dent, there is no way in hell I'm going to bare metal for that repair. I've got enough on my plate without creating extra work for myself lol.
