Is anybody these days running water/methanol injection on there turbo b-series? If so I have a few questions.. how to you control it, through your hondata or standalone system like the arm or snow performance offer? Do you run it all the time or have a one off switch? I was considering E85 but i just don’t want to spend the money to covert every thing and it not available every where you go. And plus the car sits more then I drive it.

 

@Txdragon was running it on his turbo D-series, but he just switched to E85 - he may be able to give some insight to what he was doing.

 

Running E85 doesn’t require major changes.

 

I mainly used Aquamist HFS-3 with my Power FC. Now that I'm on Haltech I'll be running through that. I use a 5 gal anti-slosh tank in the hatch with 80% meth/ water mix. It is boost pressure based so, similar to AEM, it came on at about 13-15psi ..

I will not run E85 either, for similar reasons..

 

I have the Snow Performance stage 1 kit. It is a boost-operated switch that comes on at xx psi until you let off the throttle. The activation switch gets tee'd into a good boost line, I ran mine off my BOV line; and it can be adjusted to come on by a teeny little allen screw. Lol! Anyhow, i ran this because I didn't have E85 anywhere close at first. I found a station about an hour away and just fill up and bring home 30 gallons at a time. I may run it still, I dunno. It was awesome for sure. Using 93 octane and 70/30 meth/water mix, I was able to keep some 750cc injectors at 43% duty cycle @ 364whp/325wtq, 26psi boost. Spray activated about 12psi. There are progressive controllers but *honestly*, I don't see any necessity for the extra hassle and cost when the single stage is easily adjustable. No control of it through Neptune, and I'm not sure about Hondata but I'd speculate no on that as well. Haltech, MOTEC, AEM EMS, I'm not sure.
If ethanol is not available, I would highly recommend looking into a WM kit.

 

I'm pretty sure you can set Hondata up to control water/meth injection through one of the Nitrous/Aux tabs but I'm not 100% sure.

 

Absolutely.

 

do you have a kit that you recommend that works best with hondata? And also does the Hondata have a failsafe or do I have to look into that also

 

What kind of fail safe are you looking for? You can set the conditions of when the sprayer is activated and what RPM based fuel and ignition compensations you want to run when it is spraying. There are two lean protections that you can configure which will cut the engine when the AFR gets above your desired threshold for longer than a time you specify.

 

idk maybe AEM but I rather have the hondata control everything if possible. Like if the pump give out or run out of fluid will the hondata switch map? Now does it work with the boost by gear and rpm? I use the car for HPDE days.

 

Did you run a failsafe. And does this kit work with boost by gear and rpm?

 

I didn't run a failsafe specifically. I just used the activation LED to let me know if it was spraying or not. If it didn't light up, I'd get off the throttle pretty quick. Lol! As for BBG, it works just fine there as per boost activation thresholds. For Instance, if you have it set to activate at, oh, 12psi, and you hit 12 psi in whatever gear, yup.

 

I don't know how you would tie together boost by gear and methanol injection. Hondata will do boost by gear. It will also do methanol injection. You can either have the methanol system armed all the time or there are 5 available ECU inputs you can use to arm the system. You can also set it to disarm if the CEL is on, and disarm during full throttle shift and launch control. On the conditions tab, all conditions used must be met for the system to activate. You have windows you can set for RPM, engine load (psi), water temp, and also a minimum IAT. Fuel and ignition compensations are strictly RPM based when the system is on.

For protection, I would assume you would use one of the lean protections in case the pump stopped or you run the tank dry. You could set a threshold AFR over a certain engine load (psi) and a time. For instance, you could have the car protect itself if you see over 12.8 AFR for longer than 900 milliseconds anytime the engine is over 15 psi. There are two lean protection settings so you can set one each for high load and low load.

 

Ok cool. Know do you guys recommend a certain kit over another? And can I run a on/off switch?

 

Question, if this is mainly a track car why not just run a proper fuel instead of trying to compensate?

 

No. I do drive it on the street

 

Do you not have e85 stations anywhere near you? If you do I would just run e85 and call it a day.

 

I do but I really don’t want to up grade my fuel system if I don’t have to. And when I do out of state track days I drive the car and don’t want the hassle of trying to have track down a station that sales E85

 

Sounds good.

 

Snow Performance has a good introductory price and kits available with other options; tank level indicator, progressive spray, failsafe, etc.. As for on/off switch, you mean like arm/disarm? That'd be a simple toggle switch from the battery positive, inline between the battery and relay.

 

They mainly work on actual boost pressure not boost by gear or RPM. HPDE really doesn't use boost by gear that fantastic anyway. It really depends upon the size of the track and its characteristics.

 

I’m looking into getting there stage one kit. It comes with a 3qt tank. Idk if that what you had but how long does a full tank of methanol usually last?

 

I used the smallest sprayer, I think 325ML, I used the hell out of the kit during street tuning and 15 pulls on the dyno and only used a little over half the tank.

 

does anybody have wiring diagrams on how to hook it up to a hondata so i can control it with the nitrous output.

 

That's something in the Engine Management Section to check out, or give Hondata a call and have a good conversation about it.
