Hi Rob
Stuck again,how do i configure ign outputs,read install page & i didn't seem to learn much,do i config like inj outs in reverse order.
Thanks Adrian

Trigger setups are confusing, but you only have to do this once, I've spent an hour or so this morning doing this:

The 8-cylinder one has the settings that you're wanting to use, what I'd suggest is that you use the config and tables files from the running Supra:
http://www.vems.hu/files/Fero/Supra/config.txt
http://www.vems.hu/files/Fero/Supra/tables.txt

And the 1.1.18 firmware:

You'll not need to modify your trigger hardware.

Yep, in reverse order...

I tend to wire coils in the order: Coil 00 cylinder 1, Coil 10 cylinder 2 ... Coil 70 cylinder 8.
Others claim that the best idea is wire them in the firing order (assuming 1, 3, 4, 2)
With firmware from 1.073 and up the coil numbering in h2[] is number first:
 10 30 20 00

Hi Rob
Thanks for your quick reply,that all makes things clearer & easier for me ,just got one last query today(this means there will be more later.

In Twenty Four Plus One Trigger * cylinder config page
Line as follows is this correct??

rpmk[1]=e8 #RPM constantfor 4 cyl = 3000 (=0x03E8)

thanks Adrian

ps If you dont mind when i have finished with wiring & settings will post my data for you to look at before i attempt engine start

rob@vems.co.uk:
Well spotted!  It should be:
rpmk[0]=05
rpmk[1]=DC #RPM constant for 8 cyl (12000/8) = 1500 (=0x05DC)

Before you try to start you should spin the engine over without any ignition or injection compoents in place, plugs out too!

Take a butchers at:

It gives you a step-by-step approach to configuring the specifics of your install, battery constants etc.

I'll happily look over your config and tables files, and will test them on the bench.  I've got some test patterns that you can play through your sound card to test against.
