Default Water/meth injection to avoid carbon build up 2.4DIT?

An thoughts on running wiper fluid port injection with a very small nozzle purely for the sole purpose of keeping the valves clean? Would this work?

With a small enough nozzle you could have it done on at 1 psi and I doubt it would need a tune. Not sure if itíd help though.

Might take advantage of some built in timing advance by avoiding normal (expected) detonation.

I have a sno stage 1 kit installed in my 02 bugeye. I have it routed, not to spray into my intake or intercooler, but rather to my I/c sprayers. it obv doesn't help clean valves this way. however, with my current tune, I was nervous that an injector going into the boosted area like intercooler or manifold would be too much variation for my current tune to handle. That being said, beware of tuning WITH meth injection bec if it fails during a pull or for whatever reason a line bursts, the car will run lean immediatly harming your motor almost certainly. what i want to do is to run the meth into the intake tube or even better 1" from throttle body, again, im just concerned about boosted regions bec of leaks etc.hope this helps

I just looked at the stock IC. I think you would have to tap into the plastic end cap right before the TB. Not sure if itís enough space between injection point and TB.

With this setup I wouldnít even tune (I donít know that anyone knows how to tune a 2.4 dit yet!). Just a very small nozzle and probably washer fluid. With a small enough nozzle it wonít make much difference (IMO). Might lose a tiny bit of HP in open loop since itíll run even richer. But the ecu May advance timing a hair too automatically.

The problem is water injection is not a new thing anymore. It has been around a while and it is pretty well established that you need to control it very precisely & tune for it. It would be nice to be able to run just a little to keep the valves clean, but just a little is all it takes to screw up your engine.

Try it, log everything, post results.

I am sure that with the smallest size nozzle (snow 65ml) you donít really need tuning. The amount added will not be enough to matter either in open loop or closed. Yes itíd be interesting to see how negative the trims go in closed loop. Itís probably in the single digits. It would likely even pick up some power because of ignition timing advance.

any time you mess with fueling you 100% need tuning. even adding only water will mess with the fuel ratio.

WMI has been proven to reduce carbon build up. not prevent it, but reduce it.

your biggest benefit will be from an EGR delete.

My question wasnít about tuning it.
