Replaced the pos snow controller with a Labonte maf controller and never had a problem since.

Funny, Labonte was the engineer for Snow for years...I do like his own designs better though.

The Snow controller sprays when cranking the motor. Dan changed his design and added a delay.

Might I suggest you send the snow controller back and take a look at ours -

VC-MAF - Injection Controller for Fuel Injected Engines w/ MAF

It has the power up delay that you need. Snows boost maf controller is a knock off of our older VC-MAF that we do not manufacture anymore. One reason we changed the design over a year ago is because the issue you are having, false MAF signal on start up.

Best regards,

Dan

I'm guessing you're not on the stock turbo. This is why it's a bad idea to run an MAF based controller on a non-stock turbo. The problem you're talking about goes away when flow is based on boost.

I do have a stock turbo. It's good to have a maf based kit for a small and fast spooling turbo.

I don't think flowing based on boost is completely ideal either. With the stock turbo, boost tapers off, but its still flowing a lot of hot air and g/s. Alcohol flow should not drop off at that point. What do you set MAX flow at? 14psi?

I think flowing based on injector duty cycle works pretty well for the perrin kit.

Aquamist HFS-5, hands down.

whats SMC's website?

I see that most people are recommending Aquamist, but which one is the best when running the stock turbo

They all mostly work the same and are all good on the stock turbo. It comes down to the price you want to pay with the failsafes you want and how it knows to spray whether its boost/maf/idc. Plus the quality

I myself prefer aquamist And it is what i run. I will never buy anything from Labonte as I think there way of bad mouthing other products on nabisco is wrong.

If you set your boost referencing controller up properly, the boost tapering will not cause the alcohol spray to taper.

If you run 20PSI as your peak boost, and you taper to 16PSI, simply set your max spray point at 16PSI. This will have 2 benefits.
1. You get full spray earlier, you can go more aggressive in that 16 to 20PSI range, which means not only do you make more power there than if you had part spray till 20, but you can map it to swing from 16 to 20 a bit faster.

2. You still have full spray as it tapers down to 16.


If set up properly, the performance difference is almost impossible to measure.


Aquamist is nice, but IMHO its a waste of money. Lots of bells and whistles that cost a ton, but dont make it any safer or give it the ability to make worthwhile power increases over a simple boost based kit. Of course the Aquamist guy will come in with a ton of "facts" abotu why their kit is SO much safer and will make SO much more power, however, the dyno tells a different story. The reality is that they arent making ANY more power, and that no failsafe in the world can stop that blank spot from getting to the cyl and either dump boost fast enough or switch maps fast enough. If any aquamist user is so sure, I challenge them to put a car on a dyno, and yank the plug on their alch kit at full spray at 25PSI. Nothing to worry about right? Exactly. The only foolproof failsafe is no alch kit at all. Short of that, setting your engine management up to listen for and respond to detonation is the safest way. Combine that with a simple boost dump failsafe and you are about as safe as you can ever get. The AEM kit is 400 bucks and comes with a failsafe. The Snow kit can reference MAF or boost for its metering, and metering it off the MAF will give you the same results as metering it off IDCs (actually, in my opinion, its better than duty cycle referencing, as the MAF will tell you how much air you are getting, I dont care how much FUEL I am using, I want to know how much air is going into the cyl. Take 2 cars, exact setups, but one car has 750cc injectors and one has 850cc injectors.
The car with the 850cc injectors will have lower duty cycle, and end up getting less of the spray into the cyl due to this. Now, I am sure you can set the alch kit up to compensate for that, but why?? Just reference the MAF if you are that worried about it.


I am not saying Aquamist is crap, or that duty cycle reference based control sucks, its just that "getting what you pay for" only works up to a point. And its not a $900 point. And that IDC based metering is largely marketing hype.

I agree about Labonte. Worked for Snow, left, took their designs with him, then badmouthed their products, which, at the time I am refering to, were the EXACT same thing he was selling. Some people argue that since he designed them, that they were HIS products. BS, he worked for Snow, designed them FOR Snow, to be sold as Snow products. They are Snow's products.
