Lanos 1.6 (VEMS and turbo on the way)

I loaded up the config file you sent me and it was rubbish, there's no way you'd have got an RPM with it...
The fact that your tables file only downloaded one line suggests that there is a comms problem which is screwing the setup.

I've dug out a C20LET firmware release:

The problem is i never updated the config that came with the controller, i just burned the msq file and that's it
So should i update the whole firmware or just the config?

oh and i forgot to mention that in the terminal program, if i try to send manmdV, the controller replies with charachters i don't understand, it never replies with the firmware version

Man
It's veary important to use capital M

Use the firmware and config off that C20 release then test RPM, setup your ignition, wideband controller settings from the webshop email.
then customise for your application.

bob3825 · February 12, 2009, 04:52:35 AM

oooh then the capital is my fault

rob, i'll do just that, but i never got that webshop email about the wideband, even in your guide you left some values in the wideband settings and said they should be supplied with any assembled controller but i never got those

There will have been a load of cryptic numbers on the send out form - failing that go into the webshop, and on the order details page you'll see the pump_pw and nernst values there.

Rob, i generated the config and tables and uploaded them to vems succesfully
then i uploaded the firmware within this c20let release, but i notice that its configured only for high boost, i don't get the option to choose between 12x12 and 16x14, anyway, i modified it to suit my engine but still no spark, i suspect it might be something in the wiring that slipped my mind

look at this diagram, i circled a part i don't know what that is, because what i did was connect c14 to pin 34 and d14 to pin 36, i was just wondering if this thing i don't know might preventing a signal to the coil pack

and there is definitely something wrong with all those .bat files, because when i try Manmct, it gives me the full tables file, but the download config never finishes, don't know why

gunni · February 13, 2009, 01:00:42 AM

That is a connector called C105.

You ignition pins are number 5 and 7.
They go on from the ecu to the coil driver and connect to terminals A and B.

You should double check continuity from pin 34 and 36 to the terminals A and B

I see the box labelled Coil Driver which suggests that you have a coil with built-in igniters, which will never work with the built-in igniters in the ECU.
I'm betting that you need the stepper driver for the idle control.

You may be best to find a coil pack without a built-in Coil Driver.

The tables file will download if it starts, just leave it for longer than you thought possible - or now that you use the Terminal you can type (after Man) mcd and mct which will download the config and the tables onto the screen, which you can then copy and paste into config.txt and tables.txt files.

I found the terminal to be easier and more reliable since i see what's going on, and i don't decide how long i leave it, the command window shuts automatically :D

about the ignition, if i connect it to the stepper motor outputs will it work? because i guess it would be easier if i just changed my iac

and gunni i was asking because i thought also that there could be a discontinuity so i wanted to connect the coils directly to vems

You can certainly test: http://195.159.109.134/vemsuk/forum/index.php/topic,441.0.html

bob3825 · February 13, 2009, 01:22:03 AM

i'll give it a go and see what happens, fingers crossed

bob3825 · February 13, 2009, 01:49:32 AM

If i decide to go COP, do i have to look for anything that won't work with VEMS, they will mainly be from a bmw

gunni · February 13, 2009, 01:53:19 AM

All the BMW COPÂ´s are normal inductive coils.
So youÂ´ll have to use the IGBTÂ´s instead of the stepper motor.

bob3825 · February 13, 2009, 02:04:20 AM

That's great, then i could go back to normal operation, ignition driven with ignition drivers and iac driven by stepper motor
this is taking a lot of time :D
