Looks like you will also have to remove the Lambder sensor too. Your task
is not as trival as you think, while from what I have read would work on an
older injection system, the newer load sensing type are a bit tricker, so
your calculations may get stuffed up a bit. Especialy under a fuel dump
cycle (High load cold engine and cold air) Also you may have to watch the
PWM drive to the fuel pump (Perhaps not as there is a mechanical releif
valve).

So does  enthenol like the idea of being subjected to 40 PSI? Or are you
attempting to inject a short cycle of water?

All this aside there is the octane ratting difference and the firing cycle
to look into. I suppose that you are also looking at the sensors that the
engine is using so that you can calculate the extended / change in injector
firing time period.

Try and get an engine with a separte DFI that runs its own fixed / advanced
timing angle when removed / disconnected from the ECU, so that you can at
least break one part of another loop.

Have fun, this should be great.
