When major changes like this are made you should star= t from scratch on the MAP table,=A0 (reset mode 1),=A0 center Mode 6 with t= he program knob at 12:00, and reset Mode 3.=A0 Then use a higher MP (24 - 2= 6") to set Mode 3 which is the current instructions in the latest manu= al.

=A0

I get that I am to reset = the MAP table back to original.=A0 My confusion is with Mode 6.=A0 I have t= he EC-2 and Mode 6 to set the large secondary mode is either on or off as I= understand it.=A0 I have set it to off to clear the large secondary mode.= =A0 This is done with the program knob set to 9:00.=A0=A0 My instructions d= on=92t address setting the program knob to 12:00.=A0=A0 Then I get that I a= m to recheck the fuel injector flow rate with a higher MP of 24-26=94.

=A0Mode 6 has 2 functions,=A0 Normal (with engine run= ning) of setting the post above=A0staging mixture.

<= /div>
And the one you are describing which sets or clears the large secondar= y injector mode.=A0 As always, refer to the LAST instructions you received = with the update because changes happen.=A0 Burn the old ones to avoid confu= sion.
=A0

Next do Mode 2 at lowest manifold pressure your engin= e runs at.

=A0

I don=92t understand what= I am doing with Mode 2.=A0 One of the earlier versions of my instructions = talks about increasing the range of the manifold pressure that the EC-2 use= s to make its changes.=A0 This later one talks about idle jet adjustment.= =A0 I think it may have changed during one of my upgrades.=A0 This version = is dated 7-Nov-07.=A0 Does this mode just affect the primaries and if so, w= hen does it stop?=A0 Thru the entire range, or just up to the stage point?= =A0 Right now, I have larger than expected primaries (330cc vs 195cc) and a= s a result, my MAP table is set at -127 until staging.=A0 I am certain that= this is too low, because it is bottomed out and may actually need to go lo= wer but can=92t.

No time to review the instructions so let me know exa= ctly which part you don't get and I'll try to clarify.=A0 ALWAYS us= e the latest instructions you have.=A0

Next do Mode 6,=A0 checking the staging transition fo= r smoothness.=A0=A0 Note! if staging is not smooth at the default setting I= t means you haven't got Mode 6 right yet!

=A0

Again Mode 6 is just on o= r off??!=A0=A0 Are you thinking of a different mode here?

=

=A0Nope.=A0 It has 2 uses.=A0=A0See instructions.=A0= =A0 I assume you are using just the reset mode which you do without the eng= ine running.=A0 The main function is with the engine running.=

After these steps are done and working correctly, the= n and only then should you start adjusting the MAP table using Mode 1 or Mo= de 9 (I like using 9 the best).

=A0

I recommend using the 4 yellow injectors for builders= that have the 6 port engine but there is no reason the 2 red & 2 Blue = setup from the 4 port engine won't work if you follow the setup describ= ed above.=A0 It's so smooth, =A0I can't tell when my engine stages = with this setup.=A0=A0 If your stumbles or otherwise misbehaves at staging,= it means something is not adjusted right.=A0=A0 Do not accept anything les= s than smooth staging.

=A0

There was a hiccup at sta= ging, but I think it was related to the fact that the MAP table set at the = bottom was not really controlling properly just before staging.=A0 I expect= that this will be worked out when I get the MAP table adjusted.

=A0You may be right but can't tell until all step= s are done succesfully and=A0in order.=A0=A0 Things get really confusing if= a step is skipped or not set right and then other things are done to try a= nd compensate for it.

If you think this is a complicated and difficult proc= eedure, you've never had to rejet a carburetor.
