Nick — that's the one I meant — mount it in it's own little box and job done.

Nope it doesn't — it's got minimal bits on board. It's pretty easy to wire one up.
-
Laurence - in fact even better is MS's hybrid SD/AN mode which blends between TPS for low down and MAP for higher up when the cam gives enough vacuum higher up the rev range. Spider - it's worth fitting a MAP sensor from the start, that's a very standard install. It's pretty odd not to have one at all. You can mount the standard Megasquirt MAP sensor in a small box from somewhere like Maplin and connect it up pretty easily.

MAP is preferred - more reactive than TPS
-
You are correct :)
-
What grade are you using?
-
Martin that is pretty much correct

I've driven a couple of cars with a TR5 cam on carbs and they're fine - a couple of those were in heavy saloons. It really isn't going to be an issue in a lighter GT6 Just make sure you get the compression ratio right and you'll be fine.
-
You'll want to up the compression a bit if you go for a TR5 cam. I'd go for a TR5 cam over anything "special" if you just want something with decent all round performance.

After a few requests I've tweaked the graphs. The minimum Y value is now 1 - which adds some resolution to the graphs. You can also click and drag horizontally to zoom in to get even closer to the data. I've also reversed the Y axis as I feel this reflects the needle a bit better - as the line going up means richer.

Cheers Colin!

Hi all, Does anyone have a set? I need to get some to fit my old wheels for an autosolo and have misplaced the old ones in the past 5 years they've been off the car. James
-
You need a decent breather too :) How do I know this? :)
-
Get on with it Alex :) At least you don't have 12 to do! :)
-
Difference option now added :) Just check the "Difference" box
-
You'll find that sort of stuff on EFI resources— have a google for "tuning megasquirt" Roughly — under acceleration 12 to 13 cruise 15 to 16
-
That might be a little out of scope— as its a bit beyond my maths unless someone can provide equations Something I will be implementing is a "difference" mode so you can compare the main needle to others a lot more easily. Which I think is what your graph is doing?
-
As I'm using a new way to display the graphs I have added a zoom function, just click and drag — plus added some extra data popups too.
-
Thanks all. Printing should also be more reliable now too.
-
Glad it works. I use my iPad for the workshop manual— v useful!
-
I have updated the SU Needle grapher on my site - it now uses Javascript and HTML5 rather than Flash. In short, it means it should be more compatible and will work on iPhones and iPads now. If anyone has any feedback let me know. James

I had a similar problem and it was an issue with the head gasket.

But mine drinks like crazy and gives amazing economy :) Best of both "worlds" which I do not subscribe to— it's just a car— once a modern and now no longer :) Before anyone accuses me of bias I do have a pair of lovely Dellorto (Dellorti?) on my Spitfire :) but the engine was built with those in mind, and everything else is sorted on the car to make use of the extra power— errr I just have to get it on the road now :)

Alex wrote:They do appear to be deeper on one and two by about half the thickness?.... That'll be it then — were there any specific cylinders you were adjusting more? The valves on my Mk1 head were recessed in to the head to the point they were well above the chamber.
