It's certainly a lot of time and effort! Having said that, @johnymd would have done it in a day
Talking about the sound - it has a 'whiring/wining' noise when revved. Have you got a supercharger hiding in the engine bay?
My secret revealed
Actually, no - it's the Kameari twin idler chain tensioner that makes that sound.
The last few days I've been driving around using Autotune. It's pretty damn good. Makes me feel like a pro engine tuner!
However getting a Bluetooth connection to the laptop in the car has been a bit of a trial. I've now got the ecu taped to the wing with the Bluetooth unit waving around outside. I must look like a pro too.
That's worse than looking at a mobile phone whilst driving.
I don't have to look at it while driving - that's why it's called Autotune!
Just looked at that - sure looks real purdy! I need a new chain tensioner so may as well as it's only a touch more money <gulp>.
It's a quality piece. Good for revs, head skimming and bling!
My mapping work has got it to a decent place - fueling seems good pretty much everywhere. Cold start still needs some work though.
For the record, here's a list of everything that is involved.
Speeduino 0.4.3c from diy-efi.co.uk. About £200 all up.
FAJS 45mm ITBs and TPS. £550 from https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/114026270579
Metal to make linkage £20.
Trigger wheel from triggerwheels.com, welded to the back of my Kameari pulley. £50
Ford zetec VR crank sensor £25
Sensor mounting bracket from triggerwheels.com £20
Prosport Wb02 kit. £200. I already had it. If starting again I'd go for a spartan.
Cosworth CLT sensor. £15 ebay. Fits straight in the thermostat housing.
Interpart non descript IAT sensor £15 eBay.
Used vauxhall v6 coil pack £25
Bosch 211 igniter clone £25
Swirl pot £15 from ebay.
Pierburg diesel fuel pump off my bmw! Available from ebay, £30
Aeromotive bypass FPR £120 (years ago)
Wire, plugs and tools £100.
Tunerstudio and megalog viewer £80.
Fuel while tuning £120
Also, dcoe pattern manifold and airbox that I already had. Another 450?
So all in, I make that about £2100.
Oh, and 2 used sets of Focus ST170 injectors. £50.
Speaking of which, on Saturday I found in my logs that I was hitting the configured injector duty limit of 85%. I upped the limit to 87 yesterday and retuned it. But I may have to buy slightly bigger injectors at some point.
That's seems good. Must add mine up to see how it compares
No links! Some people are just so lazy .
Thanks Jon - super helpful.I'll be combing through the list some time.
some links! Let me know if I can help with any details.
Great list! And very useful for my build as I may well take the same route.
What fuel tank are you using? Standard? 280Z?
Standard Dan. Why would you change the tank to do this?
Great list thanks Jon , its good to see it all laid out like that, I keep playing with the idea of ITB's and if you already have triple's its a bit cheaper because you all ready have the manifold etc and could sell the carbs to put towards everything else.
I may start collecting bits ,
I have to say, although my Dellortos were working great when I took them off, the process of tuning the EFI was massively quicker and cheaper than getting the Dellortos working well. Getting the carbs right was probably a 2 year process whereas the EFI has been about 2 weeks.
Recommended on EFI set ups. Slosh in the tank can cause issues but you do have a swirl pot too so probably negates it somewhat.
I thought that a standard 240Z tank was fine if it had a swirl pot and you enlarged the return line. Is there anything else? That's what I'm working toward but it's a long way from working so can't comment definitively.
