Great result - you must be happy with that!

 

Possibly good enough to dump the laminova's and CC system and run WI on it's own....

[Crabash]

I had thought that you could do that if you mapped the WI for it and you would remove quite a restriction and some weight.

[ArticMonkey]

Human error would result in the tank not being topped up IMO.

[Crabash]

It really shows how well the WI keeps the temps down its a great result Can't believe how quickly temps go up when I assume the WI is not running or low revs/load Good work with

 

It is possible we have it mapped to activate at too high a point and therefore part throttle through the corner is not kicking it in. But yes it does climb fast at low or off throtlle conditions.

[CHILL Gone DUTCH]

Are you running the laminovas with the small rad in ear ??

[Crabash]

Human error would result in the tank not being topped up IMO.

 

It tells you if it's empty, which can also be used to put car in limp to protect it.

 

Having said that for most people I would leave a cooler of some kind in there.

Enough of a result to prove there's no point in the charge cool rad though. And I have no issues with hot coolant temps as have no CC rad to block the main rad. Never got above 90 all day long.

 

Very happy, very tired, very mashed now the beer is working with the meds

Second session, WI on

 

 

That is bloody good! And much lower measured temps than my mates Harrop + WI, but he injects before the throttlebody. (No vacuum there, because there's no danger that you suck in water though a leaky nozzle..)

 

We should try your nozzle position.    Is this pure water or water + methanol mix?

Just water

[CHILL Gone DUTCH]

One thing I did notice about the two graphs is how bad you small rad is on its own Are you going to be doing experimenting with when it activated etc Do you think the people using the rad upfront (cc) will see the same results (temps) as you Or will they be lower ( at stage 2 SC ) as your WI must be battling harder because of the small CC I'm not trying to put a dampener on this for you as it's clearly working extremely well on your car and setup 😜

[Crabash]

Exmantaa, you just add a 15 psi check valve behind the jets to stop leaks under vac. Chill, dont think the min temps will be much if any different. Overall average will be lower though due to the off/low load cooling being better. But I'm confident we can improve that too when I actually set it up. Currently its on a generic safe set up hence comes in quite late in the duty cycle.

Glad, but not surprised, it worked so well. Will be interesting to see what Peter comes up with with his built-in water injection control in OBDTuner when he releases it. Last time I spoke to him, he too is basing his control strategy on IDC, plus, I think, a couple other ECU parameters. Also adding some settings for specifying the water/meth mix and using the unused PWM output on the EGR connector (still leaves the wideband input intact). Will still need all the pump, tank and injector gubbins but assume that will mean an external controller isn't needed which should save a few quid (though I guess you might need to send the ECU back to him for updated firmware).

Yeah I'm interested to see what he comes up with. Not sure if Aquamist sell the pump separately from the controller.  

[Crabash]

Yeah they do but also your system has a data connection for ecus that can handle that. Basicly lets the ecu control through the aquamist box so there are no worries about power requirements for pump, solenoid etc.

[CHILL Gone DUTCH]

Did you remap the car with WI on or just run it on the normal map Have you noticed if the AFR are ok or are they not affected by WI ?

[Acidpopstar]

Same map as we did over at yours Chris. We need to spend some time tweaking the HS2 controller and mapping over the next few weeks to get the most from the system.

 

I'm sure Crabash will be along soon re AFRs. Looking at the two logs the Target AFR (is that right?) values are identical.

 

I did have a reply from Peter after I sent him the logs. He says he has had similar results and can't understand why people are so negative about WMI. Also that it cools your exhaust gases thus making packing material last longer etc. He goes on to say we may have trouble adding alcohol because it will get difficult to tune as it's difficult to control AFRs with the system. He has some new features implemented on the new system but not WMI yet. He is dedicating all his spare time to it.

 

 

[CHILL Gone DUTCH]

You need a wideband to measure the AFRs Not sure if you have one The target AFR are what you want your AFRs to be not what they are

[CHILL Gone DUTCH]

You could look at your fuel trims but this is not very accurate

[CHILL Gone DUTCH]

That's a very good point about the exhaust wadding last longer never thought of that Have you got links for your kit you used ??

[techieboy]

Unless somebody has some temp readings that prove otherwise, I don't think heat is an issue for the wadding. Certainly not if you're using the high temp stuff. 95% of mine is pristine and the binding threads haven't even melted to let it fully expand. That's for the main silencer and the the small cat replacement silencer.
