Hey guys as the title states my cars been struggling to start first thing in the morning. I just had my car retuned on united e85 and since then it takes around 5-6 cranks in the morning and even when im leaving work in the arvo (if its still quite cool) when it was tuned on caltex eflex i had no dramas but with united e85 having a higher ethanol content its obviously struggling with the cold starts. Im running a power fc with the usual bolt on mods. Heres a pic of my crank settings...just wondering if i can adjust these and what i should adjust them to for an easier cold start. Cheers!20190605_055436.jpeg

Do you mean if it doesnt work set it to 64 in the -10°C?

Try bumping up the time in the +10°C to 32 ms and see if that helps. If it does, set it back, and try 64 in the -10°C instead.

Just an update on my starting issues. I ended up getting a brand new oem cas and took it back to my tuner to make sure it was installed correctly. It starts up first go every time now...even if i havent driven the car in a few weeks. Still runs a bit sluggish on a cold start, but once it reaches normal operating temp its perfect, so it must require some fine tuning for cold running.

      Well I had 2 choices from then on. I either had to (reluctantly) move it on to another potential buyer and take the loss on the chin. Or I stick with it and turn it into a restoration project. I chose the latter. Project Snowstorm began! The frp body kit was the first thing to go. Turns out the original colour used to be silver. The Neo and gearbox were removed, along with the prop and exhaust system before it took a trip to the bodyshop, where I wouldn’t see it again for quite some time due to the pandemic hitting very soon after they took it away. Eventually, progress began and damage assessments made. Even the front chassis leg was in pretty bad shape!     Then the chopping commenced. For these guys it was just usual routine, to me it looked absolutely terrifying!   More to follow as I’m struggling to focus on my screen at 12:45 am!!!

      That's the most absurd thing I've ever heard. I would go cut bellhousing over that monstrosity of a flywheel all day, every day. It puts a lot more mass further from the last main bearing. I've had nothing but problems with Collins in the past and refuse to ever buy their products again. I would not trust anything they tell you. He's playing his salesman card.  I'm currently at 640whp on a mustang dyno (~770bhp) with the intentions of running E85 and a lot more power this upcoming spring. Cheers,

      Nah, it's not the reduced knock margin. It is a direct mechanical effect of having to initiate the combustion earlier, while the piston is still rising, which starts to exert combustion pressure on the rising piston earlier, making the rest of the engine work harder to finish driving the piston up to TDC where the combustion pressure stops being a negative and starts being a positive. Your modern engine that only needs ~10° to make MBT doesn't waste the other 10 or so degrees of crank rotation. That's almost all of it. The difference in knock margin might go either way. Remember that modern engines to which you are currently comparing the long tractor engine (the RB) are now running super high compression, direct injection, tricky cam control and maybe even cylinder pressure sensors. You're not comparing apples with other fruit. It's apples and sea weed, or some other evolutionarily primitive vegetation. And remember, squish only really comes into play at the very end of the stroke. It certainly does good things, but it is not the biggest contributor to what's going on. It is quite possibly much less important in 4 valve head than 2 valvers also, because there is so much less squish available to a 4 valve anyway.

      Food for thought, a longer stroke motor would need less ignition timing vs. a shorter stroke motor requiring more ignition timing.

      Thanks Duncan, HART is only 10 mins from me (I did my bike license there), it'd be awesome if it ran these types of things.  Sutton Road does look good and they take fewer cars than SMSP which is good.  Surely you have enough land to lay a few million tonnes of concrete and some sprinklers D?
