"GND out" is the sensor ground. I agree that is a confusing name so I might suggest to engineering dept that we change that name to "sensor ground".

Hi Dave,
I usually find missing tooth wheels to be less troublesome. if you go to 12-1, you want the missing tooth to be near either 90°BTDC or 90°ATDC - it doesnt matter which. The position of the cam tooth is not particularly important you just dont want it to occur at the same time as the missing tooth.
-
Adamw, IF that was some erroneous tooth on trig 2, why does the polarity seem to change from the typical tooth to the erroneous one?
I don't know what these CAS look like inside to have a good theory on that - Maybe it is a "hollow" rather than a "bump"? If the OP cant see any reason for it then it will just take some careful setup of the arming thresholds to work around it.
-
The is a small artifact on your trigger 2 waveform that maybe causing a false reset. Is there some some bump or piece of metal on the trigger wheel that comes close to the sensor when it shouldnt that causes this? You might be able to increase arming voltage to ignore it, or find out what is causing it and fix it.

At idle and very light loads you can tune the injection timing using lambda, in this semi-seq case you would be aiming for lowest combined or averaged lambda. At higher loads it is generally tuned by torque output. With semi-seq I suspect the difference between optimized timing and not optimized will be pretty subtle (~1-2%) so you may have trouble actually noticing anything. Generally with mild overlap engines you will only see noticeable effects from injection timing below about 40% DC so I wouldnt both tuning beyond there.

Hi guys is there a way to get a 3d map limit so I can run separate maps for petrol and e85 the petrol has ect on the axis but would like different map limits for ethanol
You can turn on "Dual Map Limit". Set the 2nd MAP limit to be activated by the same virtual Aux you already have set up.
If I put 10 in the 5d fuel.map at a certain ethanol percent rpm does this add 10% or reduce 10% to the fuel map it says it reduces the fuel from the active fuel table .?same applies for 4d ignition .cheers
If you have a value of 10 in the 5D table it will add 10% to your main table. If you have -10 in the 5D table it will remove 10% from the main fuel table.

also did clear error codes but it keeps coming back.
What keeps coming back? The fault code or just the CE light?
-
Hi Serkan,
The aux outs do have over current protection so it is unlikely to damage the ECU. As far as I know however, a short circuit wouldnt normally cause a hardware block error so you may potentially still have some other problem. Keep a close eye on it for a while and let us know if any errors re-appear.
-
I agree, the RB26DETT is quite knock limited, at least on typical pump gas. You cannot expect to get a decent ignition map in this type of engine without audio knock detection so I would be very suspicious of your tune.
-
The analog inputs that are turned off will not throw errors. If AN temp 3 was disconnected then that would generate a fault code. The fault code will remain (and CE light flash) until that fault code is cleared.
-
Is there anything shown in the event log? (press E key when live). I only had a very brief look at your log but AN volt 5 is a bit odd, it is a power steering switch but its units display as AFR instead of Volts for some reason. Can you try temporarily turning AN Volt 5 off.

Check out race capture pro and race capture apex: https://www.autosportlabs.com/product-category/race_capture_data_acquisition_telemetry/
they are one of the few reasonably priced telemetry options that will work without a whole lot of messing around. I have used cheap 3G rs232 modems in the past but they are pretty painful to get configured and working.
-
Yes, pulse width for a semi-seq setup will in theory be the same as a true sequential set up.
-
I would set it to sequential and wire for a semi-sequential operation:
In real life there is usually very little noticeable difference in how an engine will run when comparing semi-sequential to multi-point group mode, but with semi-seq you may be able to achieve a slightly smoother idle and very light load operation.
In 360 mode your injector has to fire twice as often so pulse widths are halved and you have twice the dead time per cycle, this becomes an issue mostly only with very large injectors but I still suggest always use 720 mode if you have capable triggering.
-
Further to Simon's comment, you can also use E-throttle for idle control and dont need a separate idle valve.
You can presently have up to 3 E-throttle target tables, so to give an example you could have one for normal driving, one for when antilag is activated (which doesnt allow throttle to close beyond 15%) and another for say highway cruising that has a nicer response curve at small throttle openings.

Hi Liang,
Can you please do a trigger scope when engine is idling. Your symptoms suggest one of your triggers may be wired in reverse.
-
Pin 12 is main +12V supply. Pin 13 is main Ground. Pin 82 is ECU hold power so you may also need to connect +12V to this pin.
That should be all you need to power up I think.
-
Actually, I'm wrong, I thought it was on the request list but I was confusing it with a traction function, I cant find this feature on the request list. The more I think about this feature the more I can see it is going to get quite complex so maybe it was put in the "too hard" basket. I will raise the question again and see if we can get it back on the list...
-
I see this has been on the request list for some time. I will put another +1 on it to bump it up.
-
Was the camshaft in fully retarded position when this trigger scope was captured? If not, can you do it again with cam retarded.
-
Both versions would be set up nearly the same: trigger 1 is multitooth mode, trigger 2 is cam level mode. The engine that has both triggers attached to cam, trigger 1 should be set with 12 teeth.
for the engine that has the trigger on bottom pulley set number of teeth to 6. Also judging from the shape of the teeth, this one looks like it might use a reluctor type sensor.
edited later: sorry I see you did already mention the KF was a vr sensor.
-
It is a pull up that is needed for the IGF signal on the 1800. With the jumper on, ECU pin 9 is pulled up to 12V, with the jumper off that pin is not connected to anything.
-
The cam sensor is only to tell the ecu if the next TDC event is compression stroke or exhaust stroke, its position is not important. The actual engine position information (i.e. TDC) comes from the crank sensor.
Where did the manuals tab go?
