hey guys I put a new ecu in my car today its just another stock one for a series 2 r33, after I put it in and connected the power back up everything was fine I started the car and it all seemed to be working well. I turned the car off and put the ecu back into place along with the covers. After doing this I thought I'll go for a drive and see how she feels, but when I turned on the accessories I heard a very rapid ticking or clicking sound from the area ecu I did not try to start the car at this point just turned it off. So I pulled it all back out to have a look but it all looked fine! I turned the key again with the ecu just lying on the floor and nothing, the accessories came on and it all looked well, after a few seconds a moved the ecu around a little and the car stalled and the clicking started again much slower just 1-2 clicks a second????? It seems to be coming from that little blue plug that sits behind the ecu and is bracketed to the car???? Any idea why this would be happening? Or what it is? each click I could hear the fuel pump stopping and my safc would turn off…

a little bit further up that loom you'll find two green relays, could be one of them chattering, you may have disturbed one of them or the cables going to them. they are the ECCS relays which give power to you ecu, injectors and coils. i'd start by checking these relays.

      Slight brake pedal stutter after new pads

      Jack the back of the car up, pull that wheel off, pull that sensor out, and put a bore scope into the hole to inspect the outer casing, see if anything looks damaged before you pull the whole thing apart.

      Ergh... So I pulled the speed sensor out again and the tip was shiny so I think it's rubbing the bearing. The bearing contains the magnets for the speed sensor so I think when the first sensor broke it damaged the magnet ring on the bearing.  This is just a Google image, but there is a hole going to the bearing. So when the tip broke off the old sensor I'm guessing it fouled the bearing... As the magnet is only protected by a plastic cover it would be easy to damage it. So I guess I'm doing a bearing again.

      My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.

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

      Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.

      Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol
