Can anybody shed some light on the coil settings - I can see two dwell tables, what is the difference?
Attachment 76848
I will be putting in a COP kit in the weekend. I found some specs on the dwell time for the coils I am about to install, but no clear idea how to put the value into the KS2.0 ROM. Table 2 is a starting point, but the role of tables 1 and 3 is unclear when reading back in this thread. Getting the dwell time wrong is an easy way to either have weak spark or to fry the coils.
The first table in the coil group is the Dwell Time, in mSeconds.
The second table is the Reduction Factor, reducing the values in this table will result in more Dwell Time at redline.
Most COP coil on plug setups can be run with this table set to zero ie no Dwell reduction.
This table shown here (the third table in the coil group)
<table name="Ignition Coil, Dwell-Time Correction 2" address="122ba" category="Timing" type="2D" scaling="Percent128">
Is just the maximum Dwell percent that will be applied, regardless of any other settings in the other two tables.
Cheers for answering. Also I managed to make the tables and scalings look the part. https://www.clubvr4.com/forum/showth...gs-in-ECUFlash
Next topic I want to figure out is the alternator maps... I saw some of your posts on MLR about this for Evo 6. Have you ever found the right location in a VR-4 ROM?
For reference, Evo 6:

I have fitted a coil on plug kit which is still used in wasted spark configuration.
i understand the description of the first two tables but i dont know what is meant by the description of the 3rd table.
This table shown here (the third table in the coil group)
<table name="Ignition Coil, Dwell-Time Correction 2" address="122ba" category="Timing" type="2D" scaling="Percent128">
Is just the maximum Dwell percent that will be applied, regardless of any other settings in the other two tables.
percentage of what? and if it is not related to either of the two tables in this group what is it related to?
I have a PFL and would love the FL ecu and a good map, do you guys still do these?
Cheers

Hi Paul, we're having a dyno day on Saturday 11th September, @foxdie is still doing mapping, and I think he's still got some FL ECUs available - get in touch with him and I'm sure he'll sort you out.
Sure, all the details are here: https://www.clubvr4.com/forum/showth...September-2021
Cheers mates,
I finally upgraded my ecu to 2.0... And now I want my launch control back. Is there a Rom file with launchcontrol and antilag(I dont think a vr4 will run antilag like a evo8 right?) ? Did someone manage to create one as a base to work with?
