sorry to jack the thread, do you guys remember what is the dwell setting for stock coils if we are using INT-X? i forgot, i left it 2.0, because when i used mazsport, it was 3.5. can anybody confirm this, please....?

Bit hard the jack a thread that has died 
Not sure about stock, but can confirm that 3.5 is what is used with the MazSport coils (ie the HEC715).

what I think he is saying is
OEM = 3ms and desired is 3.5ms so multiply all numbers on the table by 1.167
which makes sense but still does not answer the question of how the numbers in the table are derived ...

Base dwell setting (not in ATR) + number from Ignitor Dwell Time (dwell compensation table). Base dwell setting = 2.0ms.
1208 at 12.75 volts/idle = 1.2ms for 3.2-3.3ms total dwell at idle.
2.4ms dwell at 9000RPM.
Since when are the Mazsport coils Bosch HECs? The connectors for Type A (715) and Type B (716) aren't right, nor is the resistance ratings for those coils (but they are close). The Mazsport ones are .5ohm primary resistance and 7500 ohms secondary.

You answered one of my questions though and that was what OEM was. I actually saw that as:
(3.5/3)*1206 = 1407
This is the same as what you said but you said "desired" instead "new".
As for the HEC/MazSport I will apologise if they are not HEC715's. I was going off something someone who supposedly had dealt with them had said.

I've "messed" with no one.
The calculation is so stupendously simple, its nauseating.
Its like someone asked how to get to the second-floor office and everyone rushed in to give answers that included ballistic trajectory calculations and GPS coordinates and a whole lot of other BS.
Meanwhile, I just said "take the stairs".

(DNEW/DOEM)*DOLD = DDESIRED
I took that to mean:
DNew = Base Dwell of new coils (3.5ms for the HEC's)
DOEM = Base Dwell of OEM coils (3ms from what I saw stated)
DOld = Old value in the dwell table
DDesired = New Value to put in the Dwell table.
Did I get it ? Or are these just ballistic trajectory calculations and GPS coordinates??

3 Days away from what?
I went with (3.5/3)*1206 = 1407 and it seems to be much better so far. Will leave it for a week and see if anything comes up and then will give the other a go.

Pulls MUCH MUCH stronger and reliably now! I think I understand what one of my issues was now to. Only taken it up to 7,000 rpm as I am still way to unstable/lean there with my intake setup. Can you point me to that thread?
