This is the same system we have innovated with zeitronix and implemented in our own shopcar. Difference in the shopcar is that it is designed to switch maps with the trigger (change boost, maf signal, add fuel) instead of just opening the wastegate.

The boost cut feature we implemented for customer cars using our meth injection systems so it would become a more cost effective failsafe than having to have the whole MAFTPRO setup in their car.

The system has worked flawlessly over the last year and a half since I designed it with zeitronix. With our direct input the zeitronix company has made all of the changes we have asked for and added them into the system.

At this point not only are SIMPLE ALARMS (one parameter trigger) available for programming, but also COMPLEX ALARMS (multiple combined thresholds that require all of the parameters combined to be met) for the most bulletproof system available.

As Jeff stated, one of the newest revisions Zeitronix has made based on my request was a programmable trigger length which the user can program to alarm for a split second and recover, or many seconds.

It was important to me that this feature was added as I have a lot of drag racing clients that I don't fully trust not to continue to push the car if there was a problem during a race. If the methanol is not flowing and it hits 30psi, cuts boost, then allows high boost immediately thereafter, it is not an effective failsafe. This way it can be programmed to cut boost for the proper time period in order to fully protect the user from themself if they continue to push a meth system on an empty tank or the like.

I will put the ZEITRONIX up against any failsafe on the market. We can run two cars on a dyno and introduce problem after problem into the meth injection system. I am confident that the one left with a fully working engine in the end will be the zeitronix equipped Evo.

 

A tested and dependable failsafe can also allow you to push the envelope too.

Thanks for the thread evoryder, I rarely see memebers take the time to demonstrate their safeguarding features at work. The last time I tried, my account was almost disabled.

Anyhow, just curious of the trigger points you chose. Wouldn't something like 14 psi at 13.5 AFR allow more freedom and at the same time protection? I figure 12.6afr, even 13.0 afr, at 24 psi is a lot safer than like 14.0 afr at 14 psi. If that makes any scence.

 

12.5:1 a/f = >
23psi = >
YOU NEED TO ADD- TPS>70%

 

TTP,

Can the zetronix be a reliable failsafe on M50:W50 or 100% water injection?
We have many rally clients using pure water, alcohol usage is banned.

 

Glad to do it...failsafe is easily overlooked till it's too late. Now I know I have a good safety blanket. Took my sweet time installing and soldering everything. Proper installation is a must.

I have mine set at:
AFR:12.6:1
TPS: 80%
Boost: 23psi
Additional duration: 3 secs

All conditions have to be met for the failsafe to be enabled.

My only lean spots that I am fine with is during spool up...definitely not a peak torque...unless I tuned for it.

Again, very pleased with the response time. I also have the knock CEL flash which is also a great tool.

Good work Zeitronix, TTP, and Tephra

 

Absolutely, the redundancy of the additional safeguard parameters such as EGT protection trigger works especially well in cases of even an issue with 100% H20 applications.

I hope that the zeitronix system you purchased from us this year went to good use on your client's car Richard. That model is compatible with all of the safeguards mentioned.

 

An imperative part of the safeguard is the proper mapping in the ECU load columns for meth and failsafe triggered conditions. Make sure not to overlook this area for maximum effectiveness.

 

^ Thats all part of tuning... I check load from 100% THrottle @ 2500 - 6000rpm+....different conditions...d
