only issue with using the flex side is that it isnt an instant change there are many delays that just wouldnt be fast enough for the demand

who is the retarded one me or my motor?
My comment was just a joke and not directed at anyone other than those 1/2 asleep drivers one sees every morning on their way to work :p

But your motor may end up being "fully sick" though you dont want to be caught withthe nitrous bottle connected up when on public roads ;)

I guessed that the jump from one tale to the e85 table would be instant :(

as its fuel changing the ecu has to take into account the usage injected it uses at said condition like idling and as it transitions from petrol to ethanol also the volume between the flex sensor at tank in fuel rails to the injectors it has to use up first

It looks like all can be adjusted.

Another thing that can come into play is fuel trims, but the application in this case is N2O so just WOT matters. AS far I know negative fuel trims are not applied on open loop .

yea im sure there are more tables that we cant see, but its still not a fast change for instant changes u need to look at timing retards and if ur using a -40c row might be able to use the OL fuel table (if richer then pe it should be used) for fueling at same time as iat retard

Assuming the retard wire outputs PWM the ideal management would be to patch directly into ECU socket for [cam phaser actual] and activate tune segment for VVT.
Caters for on-demand spark modifiers using own table to calibrate per load / RPM. I don’t think tuning WOT fuelling during PE under NO2 is an issue, I would defo go flex (e85).
Perhaps it would be cleaner with more control and tuning precision to instead have the ECU tune command the pump to spray. Fully tuned NO2 via [cam phaser commanded] ;)
I assume is SD and open loop and running dual wideband on board?
