Success!! Took some fiddling as it doesn't show the polarity on the LED or the bulb holder. So had to switch a few around while it was plugged in.



Oh and for those who wondered... Yes they do dim when you use the dimmer wheel

Had to read it a few times before i realised what you were on about.
First they came for the socialists, and I did not speak out—because I was not a socialist.
Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me.

Finally, after over a year, I have finally managed to connect to my emanage blue!
good times.

I extracted the map. So, anybody want it?  s:) :) s:)

It's a very simple map with adjustments based purely on Throttle position and engine speed.
No airflow adjustments, just injector and ignition. Quite surprised to see a pretty decent additional dump of fuel from 70% throttle onwards until about 4500 rpm. same for timing

Yes indeed. It seems my map does adjust ignition timing in the closed loop period. Which I assume will all be lost once the ECU compensates for it.
Fueling doesn't start until 50% throttle. Which I guess is around where the car goes into open loop.

So if you had the box of tricks from Lee then you could tweak the fueling map prior to 50% throttle. Having said that...do you want to? Maybe there's a good reason why Noble didn't.

What I'd be really interested in now is to log OBD2 and the emanage at the same time and overlay them, after an ECU reset. And then after a period of driving once to see if the long term fuel trims are indeed overwriting the adjustments that the emanage is doing.

I drove to some private land ...you know...that big air field around here... And did an in-gear pull from say about 1500rpm to 6000+. I need to find a way to export the data because I can't do shizzle in the tool itself.

Initial analysis; I'm missing 1% throttle! Mine maxes out at 99% when I have my foot down. Need to calibrate the throttle voltages to my car. There's an overlooked little are from using a file from someone else's car. Having said that, when I analyse the run yesterday, it does seem to "pad" the values a bit. So at 4150rpm it uses the 4000rpm map column, but at 4250 it uses the 4500rpm map column.

Likewise, at 99% throttle, it uses the 100% mapping. So I'm assuming I'm not losing anything with regards to the map. Unless it means that if the value at 100% is 7.0% increase in fueling for example, then I'm only reaching 6.93% increase... hmm

Anybody?

The other thing I don't understand, and this is also visible on the graph for timing at full throttle; timing is 4deg at 4000rpm byt then drops to 3deg at 4500 and back to 4deg at 5000.... I can't imagine why this drop is necessary?

Another funny thing.
Fueling; at 100% throttle I should see between 7 and 9% rise in fueling at between 3500rpm and 6000rpm. But the data log shows 3% increase across the rev range from about 3750rpm to 6000rpm.
That should be open loop, so can't be ecu compensating...

Latest addition. Some camber bolts for the rear. Want to experiment in the summer with running about -1.5 degrees camber and remove the rear anti roll bar.

That's all really interesting. Can you get an ignition and injection map off showing charts with MAF output v Revs rather than TPS v Revs?

I'm amazed at how much fuel is being added based on the common view that the 1zz runs quite rich as standard.

Peak torque is 4,400rpm. This is when the engine is at max efficiency so cylinder filling will be at its most effective for the higher rev range, producing the highest BMEP figure (c.172 psi), therefore reduced advance may well be required for that, (despite the higher revs at that point). At lower revs, although the cylinder filling is less effective, the revs are also lower, cancelling each other out.

Don't forget the LTFT will affect the higher rev range even in open loop, if it has been set to reduce fuelling based on the closed loop feedback it will be cutting fuelling everywhere.

Ignition timing will not be compensated for by the ECU whether in closed or open loop so will stay at whatever the remap sets it at.

What rear and front camber do you have at the moment?

Hard to say. It was aligned last when I got coilovers settled in. So, a good while ago. At that point they were at -1.03 and -1.12. Who knows now.
I'd want to try 2.0 neg for fun  s:) :) s:)  

My seized toe bolt will be sorted when I get the new subframe and toe bolts in in January.
Then an alignment with the camber bolts in.

If you go -2 deg at the rear will you leave the front as they are? What tyre pressures and sizes do you run?

I'll prob bring front down to -1.
Tyres are AD08Rs, 195 front and 225 rear. Usually about 29 front and 31 rear

Why do you want to change your current setup? Looks quite nice to me, other than the seized  toe link.

I feel like there isn't enough "give" in the rear. Hence the removal of the ARB.
And the front has a tendency to lose grip on hard cornering so maybe a bit of extra camber helps

The setup as-is is very good but the rear feels a bit too snappy. It feels like the outside rear tyre isn't gripping all it can on bends, so want to try some camber.

I'll go into a corner, choose my speed and line, dig in and then often I need to throttle a bit to put a bit of weight on the rear. But at that point, the front starts to go so I have to trail-brake a bit.

All of this is only evident about 5% of my total drive time all year, but curiosity has the better of me so I want to see if I can get it spot on

EDIT: I've tried altering tyre pressures. Going lower in the rear ruined communication and raising the front made it much worse. Won't go any softer than about 26 in the front. Even that's a bit too soft. 29 seems a good compromise for turn-in, economy, life and grip

I'm sure the toe out at the back left will be contributing significantly to the snappy rear. Once you get that sorted you may well be very happy with setup as is? Lots of rear camber may well then leave you quite understeery, especially so if you remove the rear ARB.

The two pressure adjustments you mention (lower at rear/higher at front) would both contribute to greater oversteer.

The toe definitely needs fixing. But that doesn't seem to be the whole picture. In any case i:ll try it. If. It's no good. Back it goes  s:) :) s:)

Front subframe of the two below is ready to go in a couple of weeks. Look forward to it... Not.
Got some track arms in an impressive state from our friend Matt. And brand new camber bolts. They'll all be going on.
