Ye the Y61 have a rotor that is 10mm bigger and way thicker, I reckon that will be the starting point.

That is good to know thanks. I have a feeling that 4 pots will be difficult, i suspect the disc offset isn't enough for caliper to rim clearance, and I don't want to run spacers. I might go down to the 4wd spares place and have a sift through the brake bins, although maybe I should look at an adaptor for the two pots i have already..

I'm exploring options for the brake upgrade on my truck, the most straightforward being buying the diffs out of a y61 Safari and having the bigger brakes arrive wholesale, this is tempting but expensive. The easiest is some calipers off a y60 tb42e, these are twin pot and bolt on, but seem to be hard to find. People have used R33 four pots, someone in Oz was doing a kit for a while, and this seems like a cheapish possiblity. However the construction manual doesn't have anything I can find about custom caliper mounts, although there is a mention that only OEM stuff can be used. If this is the case fair enough but if someone can clarify it for me that would be appreciated. Chur

https://www.tillix.com.au/mechanical-diesel-engine-tuning/ This is the most useful page I have found about tuning those VE style pumps.

Go with the sanding discs for sure, I mostly use 36 grit, they take a lot of material off for the first 5 mins then settle down sweet. For fine stuff 60 grit, but once it blunts it takes too long to do anything. I almost never use a grinding disc nowadays.

Fair enough. In my mind you either do it that way or do a whole lot of pulls that are logged so you have a full map, but I imagine a real time indication would be the most direct way to get where I want to get...

Keen as beans, that looks like a good way to eyeball it on the fly. Does it log the session for analysis afterwards?

Looks like @Willdat? has an Arduino lying around that I can fry.... Excite!

Shit with my google-fu I might even be able to deal with that, chur.

If i get to that point Ned will be getting pestered hard i imagine..

Ok, when I buy one I will check the spec. I imagine I will use it for a few hours max so I don't imagine longevity will be an issue..

Red= throttle, green = ratio?

Yea man, I'd be keen. Be a good thing to get my head into anyway I imagine.

I have read this page, a lot of good info. According to the internets, 550deg is the sweet spot for TD42's, I am getting 600deg under medium acceleration load but running out of fuel if I back it off. There is probably a sweet spot but I have not hit it yet, so clearly the fuel metering isn't great.

Of course it is a map sensor, I am a dick. From what I have read a wideband is still right in the spot for a diesel, so will get useful info.
