HELP HELP HELP!!!!!!

New firmware (.24 updated to .36) has different ignition outputs and my cylinders are filling up with fuel!!

Fack, guys what kind of fiendish puzzle are you trying to create here?

I have no cam sync so my old version .24 dual ignition wasted spark for coil on plug V8 is wired like this:

Coil PIN#

0 35

1 10

2 36

3 11

4 34

5 33

6 12

7 24

All but one of these is wrong now, from looking at the new configuration for the dual out. I've been trying to figure this out for 24 hours now and NO FRICKING CLUE !?!?!?!?!?

Below is what the manual says - which matches what I see in the new megatune ignition output window. By the way, I downloaded the new h[2] table - as created by megatune with the ignition set to DUAL and the tables match my old working configuration from version .24 with my special dual output firmware.

Name EC36 pins h[2] value

Drive_00+Drive_01 35+33 01

Drive_02+Drive_03 34+36 03

Drive_04+Drive_05 11+12 05

Drive_06+Drive_07 24+10 07

Do I need to re-wire my ECU outputs or what?

Please help!

Thanks!

17oct spark map as tweaked by VE autotune - at least I did not change the values myself and these are not what I entered ;]

It's extremely unlikely that VE autotune would change your ignition advance table. Even if it would change (by an error that hasn't been experienced by others), guess the chance to get such a reasonable table as result.

If looking at the fire order: 1548´6372

Put a line break in the middle and you have the cylinders that fire at the same time in each column.

1 5 4 8

6 3 7 2

Where I suggest that the coils are wired like this:

Coil ECU pin

1 35

6 33

5 34

3 36

4 11

7 12

8 24

2 10

The above settings is backwards, you want them filled in like this:

0 Drive_07

1 Drive_05

2 Drive_03

3 Drive_01

4 Drive_07

5 Drive_05

6 Drive_03

7 Drive_01

The dwell is a bit on the high side, 1.8-2mS is probably enough for your coils. 'Coil chargetimie added at 6v' seem fine.

This will probably have to be fine tuned with a timing light. Change 'TDC After trigger(deg)' until the actual and commanded timing is the same.
