Typical R34 Problems Gotten More Advanced

Hey guys.

So, I've got a 2001 S2 ER34 Skyline, It's N/A. I bought the car and drove it around for about two months with no issues at all, then I started to get the check engine light come on, the car would lose all power and run on probably 4-5 cylinders, As usual, you could turn the car off and on and the check engine light would go away, but would then come on a day later or 5 mins later, completely random.

After reading up on this being a usual problem, I took all the throttle body off and found there was cheap ebay coilpacks in there. I removed them and chucked in a mates Stagea coilpacks, OEM ones. Put it all back together and drove it around for a day with the check engine light NOT coming on. Next day, boom.. check engine light. BUT, It wasn't losing any power/ running rough. Did the same thing, turn the car off and on and the light went away. It got more consistent. So I took the coilpacks out, took the plugs out, cleaned the plugs and checked the power going into the coilpack plugs, All 12volts. I checked they were all sparking consistently and the same. All good. I chucked everything back on and everytime I start the car, the check engine light will stay on, It drives fine, no misfire, no rough running.

Today I took it into a local auto elec and had a diagnostics run on it, Code 21. He cleared it, started the car up again and boom, code is back. Car is still running fine..

Does anyone have any idea as to what it could be... I'm stumped atm.

      Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.

      Oil pan for RB25DET NEO Stagea "version"

      meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)

      I can donate $100 to your upgrade fund. So long as you can donate the IC7 my way....

      I'd love a Haltech ECU, and Haltech 10 dash. Was having a chat with Rob and Andy @ Haltech when Rob put one in his MR2. First one I'm kind of interested in too, as you can dim it RIGHT down. Andy was saying bright dashes is one of his peeves too!
