Another Nanocom group buy?

How did you work your boost out? I can't make those figures work

Erm plugged it in? Just worked really

Good tip I realised (or im stupid) if you want to save live data click the save icon first, that will start it saving then click again to stop

You have a readout specifically for boost pressure? Or is it your manifold pressure you're working it out from?

Pretty sure. Im heading out in about an hour ill check

Ah man, I don't have that. I got Engine Speed, Road Speed, Coolant Temp, Turbo Pressure, Battery Volt, Ambient Pressure, Air Flow, Air Inlet Temp, Fuel Temp, Cylinder 1-5, Acc T1 - T3 and Acc Supply

Edit: I do have Turbo Pressure

Look on the right of Ambient pressure
Battery (V) Air Flow (gr/hr) Ambient Pressure (Kpa) Manifold Turbo Pressure (Kpa) Air Inlet Temp. (°C) Coolant Temp. (°C)
13.78 57.5 97.62 98.18 21 34.2
13.75 57.5 97.88 98.19 21 34.4
13.02 57.5 97.62 98.18 21 34.4
13.88 57.5 97.62 98.18 715 -128.6

First outing heres what I got

Coolant 81.5
Ambient pressure 98.80
Airflow 56.5 (gr/hr)
Inlet 33.9
Fuel 73.6
Manifold turbo pressure (kpa) 99.54

Out for about 25mins, i assume its im °C?

Boost measured at 1.2 bar so 17.4psi. My gauge reads just over 18psi so i'd put that down to it being a cheap gauge (£30)

Did learn that my volt meter is near enough perfect, off by 0.1v according to the Nanocom

On the screen mount im not overly impressed. Its not very tight, it rattles and wasnt exactly cheap! Plus the actual suction pad is £3 off Amazon...

By my calculations, 99.54kPa works out at 0.99bar. So where did you get 'boost measured at 1.2bar so 17.4psi?

Turbo Pressure - Digits move inline with my boost gauge and went to 1.2 so I assumed bar.

Manifold pressure was on another page I think. Edit maybe I meant Manifold absolute pressure. Map sensor reading?

Ill check again when I get back to the car and post pics, youve got me confused now!

I did save some data to an SD card but no idea if it actually did, ill check tonight.

I've got;

Page 1: Engine Speed, Road Speed, Coolant Temp, Turbo Pressure, Battery Volt,
Page 2: Ambient Pressure, Air Flow, Air Inlet Temp, Fuel Temp,
Page 3: Cylinder 1-5,
Page 4: Acc T1 - T3 and Acc Supply
Page 5: Idle Speed Error, EGR inlet, EGR mod, Wastegate (which always says 0.00 but is logging data when looking in excel?!?

Definitely confused. Give me an hour ill check.

You still got your EGR? Mine reads 0 for all 3 columns.

just got a text from DHL, mine is being delivered today

Nope. EGR blanked off... Tube plugged with self tapper and plug from pump removed

Hmmmm

Ooooh, pretty graphics.

Chuck up a guide for others

Click to expand...

I made a short guide hope it may hep some poor soul just wonder if I should put it on this thread for all our new Nanocom people, or open a new thread to share
what do you think?

Here is a pdf copy for review, tell me if you cvan see any obvious mistakes or ways to improve
I use Excel 2013 and there may be differences on other versions I think some of the others limit the lines you can put in the graph.

Thanks

I've just been having a play with mine,does anyone now anything about the cylinder values?

mine seem to go between 2/3 + and - when idle, is that good?

I've had a look through the documentation but I can't seem to find anything that explains what all these values mean.

Thanks

Im the same.... All i know is as long as it doesnt go +/- 15 your alright i think....

Ok click Instruments page and it lists turbo pressure which is deffinately 1.2bar.

Then on using the other page you had up huff you get manifold turbo pressure.

Am loving my Nanocom! Need to get an SD card make up some tables next week. I want to get max values for everything.

Off to France for an off road trip which should be fun, going to have it running live see whats what.

If the cylinder balance values are +/- 3 or so, it sounds like you have a very smooth running engine. It relates to the way that the ECU tries to compensate for unevenness by altering the fuelling. It's getting a feed from the crank position sensor, so it can tell if things are running steadily and adjusts the fuelling on a cylinder by cylinder basis to achieve this. When my crank position sensor was on the way out I was getting values like -22 as well as faults logged like 'high speed crank error'. A new sensor and everything is back within tolerance. So it was a sensor problem rather than a mechanical problem fortunately. But if one cylinder is persistently low or high (like a friend's whose no 3 cylinder was usually around +13), you might suspect a fault. In that case, it seemed like no 3 cylinder wasn't pulling its weight unless it had loads more fuel than everybody else! So maybe something was leaking - perhaps a valve wasn't seating properly, there was a gasket leak, piston rings not making a good seal, that sort of thing.

That's good news then, thanks.

I've just found a spare SD card in my camera bag so will record all the data to and from work tomorrow and see what I get.

Will post results tomorrow night

as for the rattle, mine rattled until i shoved a load of blue tack between the nanocom and bracket

Added conversions to MPH, bar and psi
