Default inj batt offset for 1999 stock injectors

Anyone have the curve for this? There are no wizards for these injectors in the AEM list. The injectors are physically quite a bit different than the NA injectors, seems like they might have a different response. Is everybody just using the startup cals for a 1710 or 1720 and going with it, tweaking it if they observe a deficiency?

I'll also be looking for the curve for 550cc purple tops later.

I've searched mt.net, m.net and the google with no results.

I tuned my Megasquirt's dwell/voltage correction table by hand. Luckily I had a alternator that was dying, so when i turned on things like the headlights and/or a/c the voltage would constantly linearly to time drop below 12v. I just kept adjusting the offset at various voltages until my AFRs stayed consistent.

Sweet! Do you know where to find the table for 550cc RX-7 TII purple tops? I got them cleaned and am planning to drop them in this weekend.
