Couple of hundred miles done now, and it's all getting better and better. The logging for the FAST ECU is good, I'm seeing the AFR becoming more consistent, which shows that the tuning algorithm is working its magic (plus the fuelling table keeps being updated).
I keep hitting almost 16s on the AFR gauge when I initially open the throttle, which tells me the AE enrichment needs some work. Before each drive I add a little more fuel in, and it gets a little better each time.
My only concern now is that the injector duty cycle is still far too low, so I might need to experiment with some even smaller ones - it's easy to forget how little power a 40 year old engine actually makes...
Been following your progress on insta instead of on here!
New garage looks great.
Thanks! Really don't have much to add here right now - I've just been enjoying driving the car for a couple of weeks. I'll resist from posting all my Alaska photos up here!
The plans for the rest of summer are to just enjoy the car - I have a set of smaller injectors to fit (22lb/hr instead of 24lb/hr) if I can't the current tune right, and I'm going to change the plugs again soon because my nose definitely tells me it's running rich - so they must be pretty fouled by now.
I really need to get the alignment done, but if I'm doing that, I may as well do the tie rod ends and steering gators.... I need to do the steering rack bushes as well, and if I'm doing that, I may as well do the engine mounts at the same time...
I'm basically making excuses for not doing anything productive recently, and building a new single speed road bike instead, because instant gratification.
We did a drive up to Nisswa to spend a weekend with friends at a cabin. Ended up having to pull over after an hour of driving as something was definitely not right.
Opened the engine bay, and discovered that the two of the fancy push-fit vacuum lines had detached and started melting on the exhaust manifold. Not sure what caused them to come off, but I clipped them down, stuck it back together and the car was much happier.
However, there's an exhaust leak somewhere that's blowing into the cabin, and it's still running slightly rich. I pulled off the inlet and exhaust manifold off the other night, and fitted a new OEM gasket for them, along with a new exhaust gasket for the down pipe join - along with a healthy amount of sealant. Also filled a couple of holes in the firewall that didn't have bungs in them.
Fired the car back up, and there's a load of popping and banging, so I've probably introduced an air leak somewhere. I had actually removed the Ramair filters, so I'm wondering if that's had an affect on how much air is being sucked in. Anyway, at that point, beer was calling.
Here it is mid-work:

To replace the Jeep, I've finally accepted the fact that I'm getting old.
Whilst the Jeep was fun, it wasn't comfortable for long journeys, anything over 55 mph was quite frankly terrifying, whenever you drove it on a windy day it felt like it would tip over and it was so noisy inside that you had to crank the stereo to almost uncomfortable levels. I'm willing to compromise on a few things for the Datsun, but for my daily I wanted something comfortable, reliable, AWD and powerful. And under $10k.
So I put a low offer in and it got accepted! Picking this up from Pennsylvania next week and driving it the 13 or 14 hours home:
2012 Volvo S60 T6. I had a S60 T5 as a hire car for a couple of months over a winter, and was impressed enough to buy one. I'll try and get some pictures from the drive back, as I'll be hitting Pennsylvania, Ohio, Indiana, Illinois, Wisconsin and finally Minnesota.
Made it back. 900 miles, one puncture (tyre bead was folded in on itself - pretty terrifying at motorway speed), and a four hour nap and I have no idea how the Canoe I'm going to stay awake at work today.
But I now own a Volvo, and it's the comfiest armchair I've ever sat in.
I'm not dead or anything like that, weather has somewhat stopped proceedings.
I was spurred on to post after seeing someone on Instagram complaining that it had hit -6°C in Edinburgh..
Driving to work this week, we hit -32°C air temp, with the wind chill bringing that to -44°C:
I have been to visit the Datusn though!
Most of the way through pulling the dashboard out - there were a few wiring shortcuts taken to get it running last summer that I really want to redo. But if I'm redoing the wiring for the ECU and fitting a wideband (Christmas present from myself), then I may as well finally throw in the towel and get rid of the FAST XFI ECU, which has been the most thoroughly underwhelming piece of kit I've bought, and go back to what I know best. So Megasquirt it is.
And if I'm doing that, I may as well move towards COPs and get rid of the distributor. There's a couple of companies that have solutions for this.
Shout, shout. Let it all out. MX5's is what we're all about.
wannabe: I've got some of those with the grooves cut into them, so they look like a giant black paracetamol tablet, lol - unfortunately I can't get the trolley jack underneath the car without them, nevermind with them...
