quite interesting sensor, not sure how it works

hook crank sensor in cam input and log it :)) and backwards cam on crank input and you will see where is the problem

General Discussion / Re: RS232 Vems Tune

Actually just tried PC on both channels, display on both channels.

Second RS232 looks not working in both cases.
Sure I didn't sniff second channel if there is running some data stream or not.
sometimes it looks that you are doing things little bit backwards :) how you are going to connect laptop on second rs232 if it only provides aim stream if configured? first, have you configured it according to the instructions? I can assure you rs232 aim stream is working exactly how it should :)

Try that, but wasn't working.
Found AIM data stream on Wiki http://www.vems.hu/wiki/index.php?page=BroadcastDatastreamAim
But wasn't able to connect by vemstune or see data on the display by second RS232.
I had second RS232 wired by Vems, by order.
Issue might be that display not recognize AIM protocol on second port due different format.

Anyway I just need to receive data from ECU by display (Tested on primary RS232 just with RX pin on the display and it is working)

wtf.. you cant conect vemstune on second rs232, have you tried phone over usb-otg and select aim on it? aim format is the same on both, or you havent configured aim stream properly on it, or using old software which does not support second rs232..

Hi,

I wasn't solved yet issue how to swap between PC connection and AIM display connection. Second RS232 didn't help me but maybe other idea would.
As far I understood it seems that AIM datastream is going by RS232 till ECU detect Vems tune. This will switch AIM datastream to vemstune stream but .. there is not mechanism like vemstune timeout that will switch back from vemstune stream to AIM stream.

Would it be possible to set something like "hello timeout"  for vemstune detection ?

Problem is that I must turn off ECU when disconnecting PC and want to see display again. Also issue is that when I am connected by PC, driver don't see any data on the display which is not much confident driving when you testing things...etc.


Or how you are doing these things ?
maybe connect drivers display to second rs232 and leave first rs232 for tuning only?

Triggering / Re: Trigger Error on S6 AAN with Lupo 60-2 Hall Trigger Wheel
« on: November 07, 2017, 02:57:33 pm »
I might have an issue similar. I got spikes on the secondary trigger signal. I solve it by a capacitance between signal and ground.

Ok, I heard about something like that from the NIRA users...  what kind of capacity? 1 mikrofarad ??
i believe you are chasing ghosts...

can't say but in fact the car was misfiring when trigger error occured (ok, not at shifting but sometimes it happend without shifting and then bang!
so it would be time to change spark plugs :))

yes... because worn sparkplugs tend to missfire exact at 5500 rpm every time  ;D - but for sure, spark plugs were the first part changed to new ;-)

but maybe you can tell me what you meant with "fucked up trigger tooth" ?? ;)

how far your sec trigger is from missing tooth?

Calibration & Mapping / Re: Injector Upgrade tunning issues

Gents, I upgraded from siemens 630s to ID1050xs, they are however giving me quite a bit of grief. I am getting a real rich condition condition under boost and also under quick throttle blips. Attached are the two files as well as some logs. Got it running enough to pull some logs. Thanks all in advance.

so what's wrong here?

For whatever reason, it goes real rich at throttle tip in, so essentially of I blip the throttle on down shifts (sqs trans) it goes to 10 afr and then it settles where it is supposed to.
so maybe it needs some tuning?

timing belt slopiness or signal too close to gap

Hello,
        iv been trying to get my new engine setup right with Vems v3.8 on my ls3 style engine. It has what GM calls 58x (60-2) crankshaft sensor primary triggger and 4x cam sprocket for secondary trigger. now the problem that I am having is I don't think I have the cam sync set up right. I keep getting  TRE faults and less sec. trig faults. i Took some pictures of the VEMS trigger log for rising and falling edage of the secondary trigger. iv been playing with rising edge with the /ignore Sectrig pulses above/ with value 5 to catch the trigger at tooth 3 but not working and iv tried using just the /maximum primary edge between secondary edges/ set at 33 to catch the second cam trigger at tooth 33 and also 128+25=153 in table  to maybe catch the same signal but not working  :(
rising edge

I don't seem to be able to put any pictures on here but I can email anyone the images of the rising and falling edges of the GM 4X cam sprocket.
upload both trigger logs with falling and rising edges, after changing edge reboot ecu

so, how's dbw? got it working?

Software / Re: nice features to have "request"

One more:
Cylinder separated ignition trim. For example: cyl 5 is more likely to knock, you can retard that cyl by 2deg overall (or add rpm and kpa limitiation for the retarding), and add 2 more to the whole ignition table, that would result in more power.

Cylinder separated spark delay under base settings?...............................


 
Yeah, but you can give advance in it? I mean it shoud go negative then, but vt says out of range... Also RPM and kPa limitation isn't there.

if the table is called delay table, so maybe it is retarding ignition with positive value in table?

Configuration / Re: porsche 964 meth controlled by vems ecu
« on: October 03, 2017, 03:20:48 pm »
yes 50/50 meth water.
is it a good idea? here in Lebanon, we do not have Vems support, so if you have more details, i appriciate your help
regards
you can use anytrim to trim spark or the boost when methanol runs out.
