I am running Hydra with Phils WI harness already. It links to an Aquamist system, the two products work together on fault detection and map switching.

Phil has made a pretty big impact with the Subi crowd and the Hydra, I don't know the AEM so I guess I will have to take your word for it.

 

FAILSAFE: Was finally able to put a video together of the TTP-Engineering meth kit in action. The video was a demonstration of how our system reacts in the case of power failure. There is a lot of talk about failsafes and meth injection. I have not "seen" any documentation or proof that anyone else has actually made it work. Here is ours...

Here is a log of the a/f and boost and reaction to these parameters as we shut off the meth pump at 29psi. :dist: This is the point where most motors go "pop".

 

TTP,

I have a little problem in reading the picture, can you send a bigger version, may be 150% buigger. Any bigger will also have screen displaying problems.

Please tell me at which point you switch off the alky - is it the point where it drop off from 100psi to 0?

Is the top trace "lambda" followed by "afr" ? It will help if the picture is bigger. One more question, is it done in read time? (sounds stupid but need to know)

Hey no problem... My laptop is 16x9 in 1024 display. I figured in 640x480, it would be large. It is 700pixels wide.

 

As I am flipping the switch, 26psi boost 11.8A/F, very safe and conservative on meth. We actually went a ton leaner after this video was made.
Keep in mind, the blue line at the very bottom represents knock voltage.


Power to meth pump disabled, about 300rpms later (you can count seconds in the video) the boost drops to 21.7psi, A/F ratio drops to 10.5A/F (richer than a stock Evo), EGT's drop 20*C.


Another 268rpms later the boost settles to 20.8psi (again, safe for the street), yet now on 93octane only the A/F leans out to 11.3A/F ratio automatically where you would want it on pump gas and it would stay there until redline with our tune. I was actually in traffic on this video or I would have stayed in it longer, but you can see from the throttle position log in pink, that I never lifted from 100% TPS. The system made all the changes automatically.

What is funny about this situation is, that if you were at the dragstrip when this happened, not only would you have a motor in one piece, you would also still have a great E.T. and MPH .

Where were you back in July when we started putting failsafes out? It has been tested and used by several individuals and vendors on this site, documentation and proof is in the link above.

The AEM/SMC or AEM/AlkyControl is not the only ones either. There are other companys that have been doing this for a while and they provide several failsafes that work as well.

I still commend you for making your own but still you have not discribed how it works or how quick it works. From your log it is hard to tell, also the zetronixs only data logs at 74 sampels per second at its fastest rate so it would be really hard to tell if you recieved any knock but that isn't fast enough to detect all of it. Also when I did my testing be aware that just shutting off the pump is not a simulation of it running out immediatly.

I hope it does work to help out the people that need it but you need to provide details on how it works. What does it look for in its failsafe routine. What type of alky kit does it work with? What does the controling? Just alot of questions unanswered for people interested.

 

I did not see any proof in the above link, any video jpg's or documentation. I did however see the post that Vijay had been doing this for quite some time with the $2200 AEM Standlone as you have described once again.
Vijay is a local, a friend of mine and if he states it works, then his word is good enough for me however.

It works on the 12v supply line to the pump. If there is no 12v the pump/meth solenoid, then the map is a pump gas map for boost, timing and a/f ratio. AS PROVEN IN THE VIDEO AND ON THE LOG, IT WORKS. This is more than I can say for any others. I commend you for working on a way for it to work with AEM also, but I am not about to get into a pissing match about who did what first and which is better.

What I haven't mentioned is that I use an OBDII datalogger as well as a Link Electrosystems KnockLink as well. 74 samples/sec is a lot in my opinion. Like I said there are two other redundant systems monitoring knock also that did not show any, period.

I said nothing about running out of meth, so don't invent situations that did not exist in the video. That is covered under another failsafe.

 

For a Failsafe mechanism to be effective, it must detect the all forms of failure. Just my view.

I wouldn't really say loosing power to the pump is a failsafe at all. If the pump doesn't make pressure it will still be trying to run and it will still have power going to it. This is why I stated for you to try it and see how it works, looks like it wouldn't work.

I wasn't trying to start a pissing match but basically no tech info was giving on how the system works, what it uses or if it is even avalible. In my thread I lay it all out, how it works and how to hook it up so it can be used. You stated that nobody else has done this or proved it, that was a stantement that you shouldn't of said because it is completely not true.

I guess if you just look at if the pump has power or not it will work on any kit but it isn't a failsafe. Some protection is better than none and the more failsafe checks the better, I completely agree with that.

74samples per second isn't crap when you are trying to sample the sound of each ignition event on every cylinder at 6000rpm.

Vijay? Who he? Does it really matter? I think you get my point so I will go no further.

 

Vijay is the one with the AEM meth failsafe 2.5 years earlier than you "founded it".

Where is your video and logs? All this time spent talking but no visual data. We could of done the same, but spent the additional time and energy to make the videos and post the logs, proving the effectiveness of one of the safeguards. After all this we have someone that feels somehow we are encroaching on something they created with a $2800 system when in fact Vijay Swami from Tampa had done it with AEM long ago. Our system is about 28% of the cost of the AEM unit and out meth kit is about 50% of cost of the other kits.

I also stated we used a Tunerstein datalogger and Link KnockLink. Add those sample rates to the 74 and we are covered in any circumstance. Not one hint of ANY knock voltage on the whole pull.

No I don't see your point, and yes there are other failsafes with our system. If you took 5 minutes to quit trying to discredit our system and make your $2200 AEM + $600 alkycontrol system look superior like your ego, you would be asking the right questions about the other failsafes against pump pressure loss and meth clog.

 

so which failsafes are up and going against pump pressure loss and meth clog?

 

First of all I never said I was the founder of AEM failsafe, I just supplyed the EVOM members how it could be used on the AEM for the EVO with their specific kits. Myself with the SMC kit that is built for the EVO. A different person worked in the AlkyControl kit becuase it works very well with tuning and a failsafe.

I highly doubt Vijay was the founder nor did I state he was either. Quite putting words in peoples mouths and dragging other people into this. Learn how to communicate clearly. You are the one that stated you are the only one to actually make it work. I just cleared up your false statement.

If you want proof read my thread, there are other threads as well on EVOM, many people use it and it works I think you already know this. No where do I state its the best because it isn't , but it is better than nothing. There are several other systems that provide great protection.

I don't know where you get 2800 bucks for the system, Once again another false statement. Quit making these. You might speed 2800 if you had every possible piece for the AEM and the most expensive akly kit out there. Most of the time its probably more like 2k but remember its a free safeguard becuase most people don't buy the AEM for this or alky control, they had already bought it becuase of the upgrade path they choose.

If you read my other posts I have been trying to get you to discribe how your safegaurds work, all of them. You have not done this, so please explain your product! Explain everything it protects, all you stated is "It works on the 12v supply line to the pump" Thats it. So what am I suppose to think? I was just asking for all the information so it could be more of an informative post.

Quit taking everything in a negative fashion and back it up with the information wanted.

Thanks
