The length of the dwell ectension is to some extent dependant on the REF/SYNC mode.
The IEX can be modified to only give a 7.5ms dwell time however the timing is delayed during cranking so CRIP can only be done after the engine has started.
If you need the IEX modified you will need to return the IEX through a MoTeC dealer listed on the website.
Problem is a D585 will self discharge at 5.8 or so ms, 7.5 is a non player. I have the Denso modified one and am a dealer in USA quite familiar with the mod. Problem is I sold about 50 of the coils before this feature showed up. Previously used LS1 D580 coils that have much less power. So a return on 3000 dollars worth of coils and then buy 3000 more in coils to replace them is a real financial bind.
It is running dual edge mode as it is near impossible to change trigger positions they are built into the damper and are where they are sort of thing. I am at a loss to understand the whole loss of dwell control below 400 rpm.
Is the dwell extension a function of the initial programed dwell so the suggested dwell vs rpm vs battery volts table could work or does it just default to 7.5 ms with the IEX? If that is the case then playing with it on the bech with a scope is a bit pointless.
