FS: Venom 400 Performance Control Module
I am selling this for my friend. He had it on his 02 EX for about 1 week, then sold the car. It is in perfect condition, no problems at all, said he noticed good gains with it. Selling for $250.

Rep Power: 310 ^ just connect 4 small wires, it's best to mount the controller in your glove box, so you can flip it on and off whenever you want without having to pop the hood. don't turn it on while driving, wait until you're stopped.. if not, it goes crazy when ya hit the gas. kicks on and off like a mother****er.. lol. you can turn it off anytime though.

Rep Power: 0 i talked to him this morning. he said he really cant go any lower because it is basically brand new. it is very easy to hook up like cocky said. im not sure about the warranty, but you wouldnt really need one anyways. let me know if you want it or not.
not to be a **** block but do you know how these things work???? all they do is tell your comp that you are at wide open throttle when in actuality your only at 30%. you can get the same effect by pressing on the gas. i had 1 on a 01 s10 and ran 4/10's faster with out it. it actually floods the motor. id ebay it you can probably get more out of it there too. they are not specifically made for 1 car sometimes the units are interchangeable depending on the unit itself. i got mine form a guy at venom when i got my nitrous kit. he gave me the low down he helped design them. in so many words its a gimmick

Rep Power: 0 thats not how it works at all. it doesnt even turn on until 75% throttle. where did you get 30%? and by the way, yes it does work. i rode in his car when he had it on, and also when he had it off. total difference with it on. dont go spreading false rumors about things.
haha this is posted everywhere you want to do research on the veonm module but ill save you the searching and just post it
At first glance, you probably think that this is a joke – or perhaps a "smart-***" suggestion. But, in fact, many enthusiasts – including some within the online Saturn performance community – spend money on a particlular aftermarket gimmick that claims to do nothing more than what you can accomplish for free by literally pushing the accelerator pedal down further with your right foot.
The product to which we are referring is a gimmick known as the "Venom 400" marketed by Python Injection, Inc. The Venom 400 claims to alter closed loop fuel and spark response by replacing or modifying the voltage signals into the powertrain control module (PCM) from the manifold absolute pressure (MAP) and throttle position (TPS) sensors. Since the PCM uses input from the MAP and TPS sensors during closed loop operation to determine an appropriate fuel response, their logic behind this attempt is to trick the PCM into thinking that the throttle is open more than it actually is so that additional fuel will be added to the mixture. And since a mixture slightly richer than stoichiometric is generally best for producing peak power, the additional fuel should create some extra power (albeit far from the 25% increase that they claim.)
However, it is important to remember that MAP and TPS inputs only affect PCM decisions during partial throttle driving. Once MAP and TPS signals reach voltage levels that indicate full-throttle, the PCM begins ignoring these input signals and resorts to open loop operation – at which point, additional voltage from MAP and TPS sensors will not affect fuel response. In other words, the Venom 400 claims to function only under partial throttle conditions.
This partial throttle limitation is not something that is denied by the makers of the Venom 400. In fact, they openly admit this in their marketing material. They even publish dynamometer testing results at their website (http://www.venom-performance.com/v400/dynos.html) that show power gains as a function of throttle position. If you look closely, you will notice that the Venom 400 power curve matches the stock power curve at 25% and 100% throttle openings. And, of course, on both curves, the point of maximum power occurs at a 100% throttle opening. But at all partial throttle openings between these points, they indicate a substantial increase in power by using the Venom 400.
Specifically, at 40% throttle opening with the Venom 400, as much power is indicated as was produced at 60% throttle opening on the stock curve. And at 80% throttle opening with the Venom 400, as much power is indicated as at 90% throttle opening on the stock curve. At full throttle (100% throttle opening,) the venom curve matches the stock curve – which makes sense, since the Venom only claims to function during partial throttle operation.
Those of you who have read the previous tech articles on fuel delivery are probably laughing by now. This is because you know that the block learn feature of closed loop operation uses input from the exhaust gas oxygen content sensor to modify the PCM's response to any given set of input signals from the MAP and TPS sensors. So even if the Venom 400 were successful in altering the MAP and TPS inputs, the resulting richer-than-stoichiometric mixture would be detected by the oxygen sensor. And the block learn feature of closed loop operation would force the PCM to adjust its response to the new MAP and TPS signals until stoichiometric ratios were restored. Thus, by altering only MAP and TPS signals, the Venom 400 would have no permanent effect on closed loop fuel mixtures.
However, the fact that the Venom 400 probably does not work is contrary to our point. So for now, assume that the Venom 400 does work as claimed. And if so, then you will see that you can accomplish the same thing for free by pushing harder on the accelerator pedal.
What they fail to mention is that the amount of throttle opening is determined by the accelerator pedal – which is controlled by the driver with his or her right foot. So by simply pushing harder on the accelerator pedal, you can open the throttle as far as you want - for free. In other words, you do not need to spend money to go faster from a partial throttle position. You need only to open the throttle further until one of two things happens: 1) the car goes as fast as you want or 2) you reach full throttle and cannot push the pedal any further (at which point, the Venom 400 is useless since it only functions during partial throttle operation.)
So our advice is this: if you want your car to produce the power of a 60% throttle opening, just push harder on the accelerator pedal until the throttle is open 60%. And if you want your car to produce the power of a 90% throttle opening, just push harder on the accelerator pedal until the throttle is open 90%. And if you want even more power than that, push the pedal to the floor so that the throttle is open 100%.
This method does not cost anything, yet it accomplishes the same increase in power as Python Injection claims to deliver with the Venom 400.
have fun guy i had 1 and know for a fact how they work and how well they work i sold it and ran 4/10's faster

have fun guy i had 1 and know for a fact how they work and how well they work i sold it and ran 4/10's faster
and in case you didnt know they can custom program them to come on at any position you wish. its not a set posoition. if you are not happy with the current program you can take it to them so they can readjust it to come on earlier.....

Rep Power: 310 i can vouch for it.. it's a good buy for $250. i got one for the same price, i love it. look for venon 400 in the "other parts and products" forum, i did a review on it there. on an auto, there's no acceleration lag when it shifts with the Venon like there is stock. it's a non-stop 0-90, maybe higher.. instead of.. 0-40.. shift.. lag.. accelerate to 60.. shift.. lag... etc. it's worth the $250, trust me.

Rep Power: 0 how in the world can you relate a poor eficency domestic s10 to a civic. You change a filter on a s10 and will gain like 10 hp. Well maybe then you should stick to your ineffiecently made s10 4cyl. I though HAVE a civic WITH the 400 put in it, and like cocky said it does help auto lag. Stomping on the gas doest help, everything still cuts off for the change over thus giving you lag. With the modual on its like poping the clutch on a maual tranny, quick response. A million things come into play especially in an auto since pressure, sensors and other aspects affect the way the tranny change over from gear to gear. Let the engineers do the research on that, while us the consumer reap the benefits of it.
