Sounds like a faulty temp sender. The ECU thinks the engine is still cold, so it adds lots of fuel for a "cold start"

That is a possibility. It is important to test these things which is easy to do with a multimeter.

Go into 'settings' then 'cranking' and have a look at the 50deg and 80 deg settings.

Change the 80deg to 9.0 and the 50deg to 10.0 and see if it starts easy for you.

will this change the tune at all??

dont know much about tuning at all, just know it was dyno tuned for hours an was told that, down low on cruise he has kept it as lean as possible an at 20 psi its running rich but on its limit of knocking. an a slight change to the tune an the engine's buggered.

still waiting on new coils should arrive any day they've bn sent. other wise i'll have to plan a trip back to brissy an let mark figure it out.

Won't effect the tune that your tuner has put in place. It will effect the amount of fuel being put in but only while you are cranking the engine, not while it is running.

The other thing I should add also is, if the changing of settings makes it worse, then try the other way and reduce the figure. This is only a cheap temporary fix. It will help you determine if there is a problem elsewhere which you can then find and understand more easily.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
