Injector and Ignition Config in MT
« on: June 23, 2007, 10:33:42 am »
Hello, new user here. I am using MT 2.25 and the injectors and ignition are going to be wired in firing order, as to allow a 6 cyl and 4 cyl unit to use the same (plug and play) harness pinout.

The part that really messes with my mind is the injectors, the modified firing order (ex. 1-3-4-2 becomes 4-2-1-3 because 4 is on the inlet cycle) Would a 6 cylinder 1-5-3-6-2-4 then become 6-2-4-1-5-3?? (offset the pattern by half the cylinders)
(The "other ecu systems" do this in the background, making me a dumber person as I found out recently!)

Rob can you please have a look at my MT settings? Thanks in advance!

Injectors
6 cyl
5..0

0  4
1  2
2  1
3  32
4  16
5   8

For crystal clarity, this would fire the VEMS pins 20-9-18-7-19-8 in order correct?

4 cyl
3..0

0  2
1  1
2  8
3  4

For crystal clarity, this would fire the VEMS pins 8-20-7-19 in order correct?

Ignition (4+4 Ign Output VEMS)
6 cyl 3X2 Waste Spark Coilpack using 5v IGN
02..00

0  4 
1  1
2  0

This fires VEMS pins 35-33-11 in order?

4 cyl Sequential COP using 5v IGN
03..00

0  5
1  4
2  1
3  0

This fires VEMS pins 35-33-11-12?

It will be a miracle if this is right, its 5:30 AM and I am half asleep!
Thanks,Kevin

Injectors are correct.  Ignition is too, but the numbering is wrong

02..00

0  40
1  10
2  00

And

03..00

0  50
1  40
2  10
3  00

Cheers

Rob

Thank you!
For the ignition numbers, do you mean in Megatune it should be like that? Here is my config screen using VEMS MT 2.25 and 1.1.23 firmware.

If you're using MegaTune then its pretty much self-explanatory.  If you get a no spark then you'll need to upload-config and edit the tables by hand.
