@Ducie54 I get that if I haven't turned on a fuel mode yet.

Switch on a fuel mode and you get it, I'll add a note to the engineers to show a message "no fuel mode selected...blah blah etc"

Just fired it into the issue tracker, cheers @Davidv

Just a note 

If you go to add calibration data to a sensor, use Cal table 1, if you space them apart at say 0.5v, 1v, 1.5v etc 

It ends up reverting to full numbers and then does weird stuff if you look at it in the map view by pressing K 

So the cal tables need some bug fixing to be usable (unless it's a quirk of this empty basemap)

 

So basic engine/idle theory... **assuming your trigger1 offset is correct**
engine power output is from compressing & igniting fuel + air. The more fuel + air you have in the cylinder, the more potential power. The ignition angle (ie "when" you ignite the mixture in the 360* cycle) determines how much of that potential power is actually created. In 95%+ of petrol/ethanol engines, you "control" the air intake, and the computer/carb adds an appropriate amount of fuel to match.
To have a stable idle, the engine output power (torque) must equal the amount required to keep the engine turning over. Any less & it stalls, any more and the revs increase.
So the 2 levers you have to pull to get a stable idle (at any rpm) are
1) how much air you let in
2) what ignition angle you fire the spark plugs at
You are only changing #2 here, but it sounds like you have #1 a bit off vs the factory specs. 25* ignition at idle is quite high, so I suggest you need to increase the air flow at idle - either idle stop screw on the throttle, or increase the idle control settings in the ECU to allow more air. You will then see your idle jump up to higher rpm, and when you reduce the ignition table values it should come back down. I cant give you exact values, but typical factory ignition idle angles are usually in the 10-20* range, and in your case it sounds like the manual says 5*. You dont have to match this exactly as your idle numbers can also differ from factory, but its usually a reasonable starting point.
You are extremly unlikely to have knock or other spark related damage at idle speeds, so there is no real "dangerous" ignition number for idle, its just what works well for your car. Knock only becomes an issue as the engine comes under mid-high load (note that low rpm can still be high load however when you press the throttle hard)

We have a really nice colour display:

Completely customisable, you can display any parameter inside the ecu over CAN Bus.

UPDATE!
So i have connected my Racepak IQ3 street dash finally after 3 days of tinkering around with the software. Turns out that when i installed the program from the USB Drive, I needed to download all other data for IQ3 dash configurations. It wasn't giving me the EFI channels for the Link ECU configuration. I followed the steps on Racepak's Datalink2 software to configure for link (emailed tech support) and then i configured Link with the instructions that Adamw posted above. I have only tested water temp and TPS so far. I have not checked if everything else works because I haven't finished setting up the ECU. i need a few more sensors before i start up the car.
I appreciate the help!

Thanks all for your help guys!
It turned out to be fuse number 11 in a fusebox I didn't know existed!  Hidden away behind the immobiliser keypad, which you have to pull off it's hinges to reveal the fuses.
Apparently this fuse feeds Engine ignition system and SRS airbag.  It pretty much immobilsed the whole car!
Not sure why it blew, perhaps I have an underlying fault that will come back to bite me!
Thanks too to https://shopbhp.com/ - great tech support as always

Unfortunately that log doesnt contain values for TP Error Accumulator or TP/Target Error Accumulator. If we cant fix it here, add these 2 into the logged parameters for next time so we have better info next time it faults.
For now, we can see here that the accel pedal has no issues and rule that out - both main and sub track nicely together and show no AP errors
Comparing TP main & Sub we see the 2 of them track together quite nicely so its unlikely to be a TPS error. These 2 values seem to be within 0.2 - 0.3 at all times which is fine.
comparing e-throttle target against TP main & Sub postitions however, we see that every time you get off the throttle, the TPS postition almost "bounces" back up a couple %. Usually this is caused by PID setting issues in the ethrottle control. in your case it looks like they might be a bit too aggressive, and its causing some pretty bad overshoot (and for it to not quite oscillate, but still jump back in the wrong direction once it overshoots). This screenshot shows the worst example I could find of both the "bounce" when you go from full throttle to 0%, and for general poor tracking of target -> actual TPS angle. Note the blue TPS line overshooting by 10% ish repeatedly between 10:04 and 10:08. There is another good example at 13:40 +/- 5 seconds.
I'd suggest setting your ethrottle to "always run", then with the engine off, tune your PID settings a bit while logging these same values, until you get TPS to track target reliably thorugh both slow and fast throttle transitions

Correct.
 

Hi guys,

I'm based in the UK, send your basemap to [email protected] or attach it here.

It's a graphics driver issue, fixed it for 5.6.6

I think its much better to have all universal function like virtual aux, timers, 4D, 5D, fual fuel table etc. than a dedicated NOS function. This way you can build your own NOS function excatly how you want it. You just habe to be a bit creative with the universal functions. 

No no no, we're not releasing two new plugins. Fake news.

Here is a video I did on that subject.

Yeah IATB is the better option. Faster acting.

You havent logged a lot of parameters so its hard to check exactly how this happened, but yep your log says you had 40.6* at 185kpa. 
Looking at your config I think this has happened because you have dual ignition table set in overlay mode (ie table 1 + table 2 = value to use). Looking at the rest of your config you either didnt intend for this to be used at all (4d ign used instead), or you intended to have it in interpolate/switchover mode between the 2 ign tables (table 2 is roughly 1* higher values than table1, and your "enable" switch for table2 overlay is the say DI9 meth switch you use for 4d enable). You probably want to set dual ignition to disabled given you are handling this in 4d overlay anyway.

Guys relax a bit. 
I've mapped and I'm supporting several 600-800hp 2.0 to 2.3l time attack engines/cars with a Link ECU and multimap strategy.  Such an engine runs usually for 5000 race track kilometers until a rebuilt is needed. That's a similar distance to a 24h race.  I like to answer your question.: 
All LINK ECU use the same PC-Software and the same Firmware. The main difference between all LINK G4+ ECU's is only the hardware.
your tuner should tune the main Fuel and ign Maps from the lowest to the highest boost levels. There are 3 main Boost Maps in the LINK ECU. You can additionally span one of the axis of the Boost Wastegate or Target table to a driver Rotary Switch. So it's possible to have up to 33 different boost maps, which all can be switched on the fly. 
On top of that, you can activate 4D fuel and ignition tables on one or several of the boost maps. This allows trimming Ignition and Fuel on some maps if you or your tuner like to do that. 
The Link Ecu is really flexible. Usually, the only limit what you can do is the creativity of the tuner. 
As an example, we installed 3 rotary switches in a Time Attack/ Hillclimb car.  One 12-Position Rotary Switch is used to choose between 12 different torque maps (mainly altered by boost strategy). The Launch RPM can be chosen over another 12-Position Switch, depending on whether and Track conditions. And lastly, we have a 3-Position Rotary Switch to choose one of 3 Drive by wire Throttle Maps.  
For engine Safety, we set up Limits for too low and to high Coolant temp, Oil temp, Oil press and Fuel press. We are also using full time closed loop lambda and sending a lot of Data over a custom CAN. 
As you see, the LINK is a very capable system.  But as every ECU, it needs a capable tuner to use it properly.
