It will be no less accurate than the current ignition, but you can map it.
Yes the timing will 'walk' a little bit with rpm, but again, you can map it to compensate.
The bigger issue has been controlling the fuel side of CIS-E in a more sophisticated manner than WOT enrichment. Been working on it for a while, and IMO there is a solution, but I am not convinced that it is not better to just use Digifant hardware and make it simple to integrate an aftermarket ECU. I am converting my car with DIYAutotune's help, and will have some data on area under the curve for both setups to compare.
I think I've gotta argee with you Chris, given my choice I'd just do a digi conversion.
