i tell u now it does NOT run like a crap box

I have a Mines ECU in my 32 GTR as well and it runs very nicely. its not running over rich and it has a hell of a lot of power for a standard GTR. It holds its own next to my mates GTR with pfc, cams, turbo back exhaust, and running 1bar boost!

if u use a mines ecu ur car will run like a crapbox :)

There is nothing about the mines ecu that means a car will run poorly (or well) just like a PowerFC or any aftermarket reprogrammable ecu; its all down to the tune.

If there is a problem with the mines ecu, its that there are very few tuners outside of Japan (and particularly Mines) that have a way to reprogram it, so you tend to be stuck with whatever tune was last performed in Japan. Given the fuel differences, that can be a problem.

gazza750: The safest (and cheapest) thing to do for the time being is to whack it on a dyno and check the air/fuel ratios. Once you have those you will have a much better idea of the suitability of the tune and whether its necessary to change the ECU straight away (i.e. if you discover its running lean and might damage the engine) or can put it off for awhile.

I also have a Mines ECU for my R32 GTR. Does anyone want to swap a standard R32 ECU for my Mines retuned ECU??

It's currently running very well on the car and also has the 180km speed limiter removed, which is great for track work and drag racing. But they cant be re-mapped due to the epoxy glue over the chip.

Im willing to do a straight swap!

    • I think the concept is highlighting the various scenarios where thicker oil helps, and thicker oil potentially doesn't help and only generates heat and costs power, in turn for safety which isn't actually any safer (unless you're going real hot). If anything this does highlight why throwing Castrol 10w-60 for your track days is always a solid, safe bet. 
    • Jason should have shown a real viscosity vs temp chart. All the grades have very little viscosity difference at full operating temperature.
    • Oops... I meant to include the connector  view... BR/W - power from fuse L/W - motor negative to fan control amp (and off to HVAC pin19) OR/B - PWM signal (from HVAC pin20) B --  ground  
    • Yep, if you are applying filler it sounds like there is something wrong with the body lol. Safe to assume there is going to be a lot of sanding going on if your still applying fillers.  Picture a perfect bare metal panel, smooth as glass. You lay down your primer, it's perfect. (why are you going to sand it?) You lay down the colour and clear, it's perfect. No sanding at all took place and you've got a perfectly finished panel.  You won't be chasing your tail, sounds like you were prepping to start laying filler. If your happy with the body after the sanding, there is some bare metal exposed and some areas with primer, no issues at all, start laying the filler. You are safe to lay filler on bare metal or primer (of course check your technical data sheet as usual for what your filler is happy to adhere to).  This isn't a 100% correct statement. There is primer that is happy to adhere to smooth bare metal. There are fillers that are happy to adhere to smooth bare metal. Just make sure you're using the right materials for the job.  Typically if you are using filler, you would go primer, colour and clear. I've never seen any instances before where someone has laid colour over body filler (maybe this happens, but I haven't seen it before). So your plan sounds pretty normal to me. 
    • I don't think there's any way someone is push starting this car.. I honestly can barely move it, and moving it and steering it is just flat out not possible. I'm sure it is, but needs a bigger man than me. I have a refurbished starter now. The starter man was quite clear and consise showing me how nothing inside a starter really should contribute to slow cranking, and turned out that for the most part... my starter was entirely fine. Still, some of the wear items were replaced and luckily it didn't show any signs of getting too hot, being unfit for use, etc. Which is 'good'. I also noticed the starter definitely sounded different, which is a bit odd considering nothing should have really changed there.... Removed and refit, and we'll pretend one of the manifold bolts didn't fully tighten up and is only "pretty" tight. GM only wants 18ft/lb anyway. I also found a way to properly get my analog wideband reading very slightly leaner than the serial wideband. There's Greg related reasons for this. The serial output is the absolute source of truth, but it is a total asshole to actually stay connected and needs a laptop. The analog input does not, and works with standalone datalogging. Previously the analog input read slightly richer, but if I am aiming at 12.7 I do not want one of the widebands to be saying 12.7 when the source of truth is 13.0. Now the source of truth will be 12.65 and the Analog Wideband will read 12.7. So when I tune to 12.7 it'll be ever so slightly safer. While messing with all of this and idling extensively I can confirm my car seems to restart better while hot now. I did add an old Skyline battery cable between the head and the body though, though now I really realise I should have chosen the frame. Maybe that's a future job. The internet would have you believe that this is caused by bad grounds. In finding out where my grounds actually were I found out the engine bay battery post actually goes to the engine, as well as a seperate one (from the post) to the body of the car. So now there's a third one making the Grounding Triangle which is now a thing. I also from extensive idling have this graph. Temperature (°C) Voltage (V) 85 1.59 80 1.74 75 1.94 70 2.1 65 2.33 60 2.56 55 2.78 50 2.98 45 3.23 40 3.51 35 3.75 30 4.00   Plotted it looks like this. Which is actually... pretty linear? I have not actually put the formula into HPTuners. I will have to re-engage brain and/or re-engage the people who wanted more data to magically do it for me. Tune should be good for the 30th!
