boosted hybrid

I was always wondering why Hondata hasnt released a boost controller solenoid that would allow for gear based/load based/rpm based boost controler similar to the AEM, or even the Power FC. The idea just hit me, Hondata released the nitrous control with a simple input/output feature running from the stock computer. The nitrous control allows for rpm/load based nitrous injection with the input/output controlling the action. My idea is using a dual stage boost manual boost controller similar to the turbo xs dual stage. You could use the input/output feature with the nitrous control interface and control the boost per rpm/load. I havent really looked at the nitrous program yet, but there might be a gear based selection as well. If there is, then we have a gear based/load based/rpm based boost controller now for hondata...

Damn, now that is doing some thinking I love it. I really like how the AEM EMS controls the Boost and would love it even more if the Hondata system was able to do it, too.

I think the people at Hondata should look into this and see if it will really work and then they have to make an interface to work with it. They will have to determine the frequencies of the common boost soleniods to make it work though. <- Something i remember reading on the AEM EMS board.

dope idea.. are you going to try it?

a little OT, but you have tried out the "auto-tuning" feature yet with a wideband 02? Just wondering how it worked out for you.

I was suprised as well to find a boost controller based on rpm/load. Its been mentioned a few times on their boards, but no answers .

There is no gear based selection in the nitrous controls, just mph input.

That's funny cause I was waiting to buy a boost controller in hopes that Hondata would suprise us with a gear based boost controller. My swap is almost finished so they better hurry up!!!

And as far as this is concerned, couldn't you just use the MPH to control it??? Forget about the gears. Only activate this feature when you were racing. Find the MPH in each gear at redline (or whatever desired point) and when racing it would increase boost with every shift. (That is assuming you were super consistent) So on second thought maybe not such a good idea. **shrug**

I think the problem is not in the code (programming) but in the actual output control. From what I understand, the NOS is a on/off thing. Controlling boost requires something similar to the IAC valve, where the unit is feed a pulse code modulation signal. The are no other outputs like this on the ECU, and I don't theing the A/C switch Hz would be fast enough to control boost... But I'd still like em to try also. Mabey a small piggyback module? I already have the silver box right? (Blue to you new guys)

It would be awesome if this worked, but I emailed Hondata a while ago and they had no plans for boost control. My guess is because it's not some thing quick and easy for them to do.

There is only 1-mph input that is functional when the system is armed, for instance I have mine set at 20 mph, it won't spray under that speed.

He was talking about using it with a turbo xs dual stage boost controller though, which is also just on or off. You would set up two boost levels and use the nitrous control to switch to the higher boost level at a certain mph or rpm. I dont see any reason why it would not work just fine. Good idea!

I have used the autotune and didn't like it. I would rather do everything manually. Easier for me.

Correct, the turbo xs dual stage is just a on/off on the solenoid from a 12v signal. Its simple and will work with the exsisting interface that hondata has created with the nitrous control. The whole boost control solenoid controlled like the AEM does would be great, but you would have to flutuate the voltage to the solenoid, not something that the nitrous control can do. I will be wiring it up and trying it out very soon, I'll post on the results.

For some you who didn't know.. YOu can also interface Nitrous contol to your Greddy profec B.

Dee

uhhhh.. I think I'll just stick with using my AVC-R.

boosted hybrid

You could use the profec solenoid, but you would lose the balance or gain function to sharpen the response of the boost. I have the profec b in my car at the moment, but I will try this with a dual stage manual boost controller with the nitrous interface on a built d-series. I am mainly looking to keep boost low below a certain mph which the nitrous control can do, then switch to a higher mph at higher boost when traction becomes better.

KOTSEMOTO

Why?

There is a spot at the back of the Profec brain where you coud plug a simple switch for the remote function.... why would you lose the gain and balance?

boosted hybrid

I have the remote button the profec b, but that isnt what this post was about. That is still letting the profec controller control the boost channels, gain, etc. I am talking about strickly letting the honda ecu control the dual stage boost controller, independent of the profec b controller. It would save money, keep everything more stealth in cabin and hands free operation of the vehicle when driving.

does hondata have a switch or button incorporated with switching nitrous control on/off, or would you most likely have to design and implement one yourself? in theory your idea seems like it would work and be most successful at the track and any other race from a dead stop, but i was wondering how the nitrous control would function when not in boost? for example, if you are only going part throttle on the highway and it switches to high boost, that is no big deal since you're still not getting into boost, but what happens when you drop below the preset mph level. will the controller automatically reset itself, or will some sort of relay have to be set up so that you will be back on low boost the next time u start moving again? sorry if any of these questions seem dumb, i'm not very familiar with hondata's nitrous controls.

boosted hybrid

The honda ecu controls the nitrous solenoid by sending a constant 12v signal to keep the solenoid open to spray the nitrous at the mph or load setting you have hondata set-up for. Once the load or mph drop, depending on what you have the nitrous field in Rom Editor set-up for the nitrous will solenoid will lose the constant 12v signal from the ecu then shut off the nitrous.

Applying this to the dual stage boost controller, under a certain mph or load you would have the first stage of the boost controller. Once you the set mph or load the 12v constant power from the ecu would turn on, then kick to the 2nd stage of the boost control. You can set the load and mph in conjunction with another, so if you are doing 80mph and your at lower-mid vacuum then you wouldnt be using only the 1st stage of the boost controller. Once you go to higher vacuum or pressure if you have set the Rom editor up in such a way, the 12v constant would switch on and kick the 2nd stage of the boost controller in. It easy, only 1 wire from the ecu to the power wire on the solenoid.

hurry up and try it lol.

hybridsol

Sorry didn't fully read post

I think this is a good idea... but why would you want it? I understand the dual boost setting thing, but I personally would want a button or switch- not the ecu to control it-

If you do it based on load, then you still spin the **** out of it in 1st and 2nd when in full throttle

If you do it based on MPH then you have to be at a certian point (like 3rd or 4th) when you can't be in two gears at once, which only happens in 5th. For example, above 50 let's say you switch to high boost... and your crusing in 5th gear... why bother?

Just trying for the understanding.... I'd like to see gear + load based system... hence the buttton. (I don't think these exist, cheaply)

Thanks...

I prefer to let the ecu control the switching of the solenoids for hands free driving. When I am at the track, even my profec b remote switch is a little distracting when driving. Letting the ecu act as the controller and be able to concentrate fully on driving the car is the real ability here.

From the nitrous screen you have the selection of the following:

Minimum engine speed, Minimum engine load, Minimum throttle, Minimum vehicle speed and Maximum engine speed, Maximum engine load

You would make this work alot of different ways. Take for example getting full boost of 8psi at 4500rpm. In 1st, 2nd gears you hook up and want more boost in 3rd, 4th gears. You figure out your mph in 3rd at 4500rpm, and set the solenoid to switch on to say 12psi. The switch on point is also based upon throttle %, mph and rpm. Under these conditions you would need to be in 3rd gear acceleration run to make the engine switch the solenoid on, which is what you would want in a drag racing situation. You dont have to take your hands off the steering wheel to hit a button, it happens seamlessly and your attention is focused in front of you. You can set the mph to shut off the boost in 5th gear to prevent high boost to save the engine. There is many, many combinations that you can make work.
