im just saying guys, dont let the evom members see this stuff. Its bad business, im not saying i know everything in the world but i know enough to see what will work well for my car and wont. The selling point for me usually is price and customer service. I have talked with TTP on occasion and generally they seem cool. I have only looked over the aquamist site and haven't talked to them. Honestly, im unbiased about either of you. I just think arguing in a medium like this causes friction and puts a bad taste in people's mouths.

 

Come on guys, lets all get drunk and stop having our cars have all the fun...jk but seriously, there is no need to argue like this, it gets you no where...

 

It boils down to the installation, not the name - well, for the most part.

Anyhow I am biased towards Snow - but haven't used any other brand

 

As a thread starter, have things moved forward for you?

or got completely turned off by the over-zealous contributions?

 

well i am still in the same spot i was when i started the thread. I want a meth kit that is relatively safe but i hear this and that about failsafes which confuse me. I just want a meth kit that is reliable and will warn me and also help prevent my motor from going boom. I hear the snow performance with SI is good but then some other people are saying it isnt enough.

 

There is plenty of info here and at each brand's site. It's up to you to find out about the system operation and failsafe. My best recommendation would be to do your research, and decide for yourself but if you have more specific questions you might make progress instead of "what brand has best failsafe for the buck?" That just makes vendors yell at each other for they each know they carry the best product

All are good, some cost more and are more of quality but that won't do you any good if you pay a friend to throw it on your car carelessly

Good luck

 

Snow failsafe would not help if it developed a leak "post flow sensor". Any kit would suffer from the same problem.

This is why EGT and AFR safeguards supercede mechanical ones like that.

I would look at meth systems and safeguards as 2 separate modifications. Pick a meth kit, then choose a safeguard. You should be using a competant wideband with datalogging capabilities first of all with methanol injection. Tuning by sight and memory is a ridiculous way to tune. If you chose a Zeitronix wideband, you can start at the $274 base unit and add the safeguard trigger LED and siren with trigger for $65. If you wanted the EGT based trigger, you would add $77 for the EGT. You could also combine triggers with the new units such as 925*C AND OVER 12.5AFR. This would be the cheapest setup for EGT+AFR based safeguard.

One thing you can't do is look at the Zeitronix as a meth safeguard. However is has this awesome function to do so better than anything else available, it is designed to be a wideband and harcore tuning tool. Something you should really be looking into anyhow to get your meth tuned AND keep tabs on the HEALTH of your system.

With kits that have pumps fail 3 times in a year as stated by another member, you really need something that can help you keep your eyes on the road and give you peace of mind.

 

there are 2 company using flow sensor for failsafe. Snows will only trigger the failsafe when flow falls below the "one fixed flow" limit. Aquamist DDS3 has user definable "lower AND upper" flow limits. Outside of this window, failsafe is triggered.

 

That is a good point. I would like to see this upper limit failsafe in action, with a video or something. Its an interesting feature.

While that is mentioned, the Zeitronix also has a programmable "user input1" 0-5v aux input that will allow under and over variables to trigger the safeguard just like the DDS3 and at no additional charge. You would not even need the EGT for that. $274 (ZT2) + $65 (ZAVT) failsafe. I guess, this would be the "cheapest route" to go and also have a wideband that logs, RPM, TPS, flow sensor voltage, Lambda, AFR for up to 9 hours!

You can also combine complex safeguards like: IF FLOW VOLTAGE <2.5V AND AFR >12.5AFR, THEN TRIGGER, and also IF FLOW VOLTAGE >4.0V AND AFR >12.5, THEN TRIGGER.

I should have my first shipment of these new Zeitronix with version 11 features in hand tommorrow or Fri. These are very exciting times for engine safeguards.

 

When my car was tuned with the Aquamist DDS3, i had the upper limit set too "low", it kept reverting boost back to WG level. A few clicks on the potentiometer solved the problem

 

nice marriage of failsafes: Zeitronics + Aquamist!

 

with the zeitronics....if it does warn me of a problem what drops the boost to wg psi....I thought if you have a warning from the zeitronics it has already done damage becasue its already too late.

 

Huh? No.

The thresholds are programmable. You can set it from 392*C to 1050*C for EGT.

You can set any combo of BOOST and or AFR.

You can set any combo of flow sensor low or high voltage.

It will stop the potential for damage well before any damage and is lightening fast in its reaction time.

The boost is reduced by a WG pressure bypass solenoid that passes boost directly to the WGA if a safeguard is triggered.

It can also switch maps on AEM and MAFTpro (probably many others) when signal is triggered also.

 

Fixed limits for the Snow Safeinection are either 150ml/min (SI-05) or 325ml/min (SI-10),
That is the one week point it has, and is why I made sure that this won't happen (better not). I kinda went overboard with reinforcement

Of course the Aquamist DDS3 and whatnot is superior in precision and even saftey - I would love to have something like that built into my car. But with the $139 I spent on the Snow failsafe I am happy, if less than 5gph of methanol is reaching combustion, the boost will never reach over 14psi, period. Disclaimer, everything was a PITA to install the way I did (everything in eng bay) and it's not really a bolt-on and your set type of system

 

you added a pressure switch to the snow si for your system?
