just get a $20 aftermarket smaller throttle rotor.. it accomplishes the same thing ...

the VEnom 400 unit tricks the ECU into thinking the throttle plate is open more than it already is. There is no real HP gain ... just when you push the gas pedal .. the ecu thinks its pushed in a little farther than it is ... and the Venom 400 doesnt even function at WOT

You sure it operates on the TPS or is it the MAP? Either way you're right on what it does.

This is probably one mod that can be felt by the butt dyno, though.

the venom unit taps into both the TPS and the MAP -- at least it did on the 02 civic installed it on.

do you have an opinion about the Venom or did you just want to say that it taps the map and tps? My friend has it on a saturn and it made a huge difference in speed and horsepower. From what i know its suppose to change the fuel map too. So not to bad of a device, but not worth the money for sure.

thumbs down for me.

 

I GOT THAT BS 5 YEAS AGO ITS A WASTE.

I guess you dont read...

i told you what it does in my previous post. A $20 smaller throttle rotor or simply pushing the pedal down further at partial throttle accomplishes the exact same thing

Here check out this link. It says that it does alittle more than "act like it changes the rotor size." Tell me if this info is inaccurate. Like i said it made a diff in my buddy's saturn. But not worth it for the money that you have to pay.

I read your post

Ok first realize this .. the Venom 400 is taking the signal value from the TPS/map changing the value to an increased value and sending that to the ECU insted. This ONLY works at Partial throttle. At full throttle these signals are IGNORED by the ECU.

Now here is an example with random values and percentages:


So Normally you push the gas pedal at 20% TPS/Map sensor values are X and Y so the ECU interprets the values and tells the injectors to spray Z amount of gas

So VENOM 400 you push the gas pedal at 20% TPS/Map Sensor values are now X+1 and Y+1 and ECU is now spraying Z+1 amount of gas


So you think hmm it sprays Z+1 amount of gas now wow .. feels more powerful with the pedal at 20%... but what you fail to realize is that if you simply pressed the gas pedal to say 30% you would get the same X+1 Y+1 and Z+1 benefit.

Technically you dont GAIN any horsepower. Your gas pedal is just, in a sense, more Sensitive.

Want to make your gas pedal more Sensative? $20 smaller throttle rotor. When you press the gas, the smaller circumfrence opens the throttle plate more with less pedal depression.

 

zilvers got it down.

As I wrote above, you'll feel it on the butt dyno. I'll bet you if you put it on a real dyno, there won't be any power gain, because the throttle can't get any wider than WOT.

 

Ok your right on the dyno #'s, nothing amazing. but the one thing about this product that might go into consideration when your about to buy it is the fact that this product can turn off with a flip of a switch. Then you don't have to have that "20% smaller throttle rotor" on all the time. It also acts differently for automatic transmission too. It changes the shift points and allows you to stay in gear for a longer time (higher rpms) without having to stomp on the gas.

Remember i did give it 3 yes 3 's. You guys are trying to make me say that this product is completly usless. And if thats the case i can't do it. it helps...just not alot and its not worth the money. If they brought the price down to 50 to 75 bucks than...even i'd buy it, cause you get a cool VEMON sticker!!

Please explain how the Venom 400 minipulates the shift points on an Auto Ecu by sending modified TPS/Map signals. Funny this feature isnt listed on Venoms Product page for the Venom 400

http://www.venom-performance.c...#v400

 

not worth it.

 

I don't know how it does it. I'm assuming that it has something to do with the amount of gas and air and how the ecu reads it. But we ordered two of them: one for the 97' saturn sc2 and one for the 97' Acura CL, both have an automatic transmission and they both act in the same way. This was when we we're testing the difference and we came to a conclusion that the new shift points when the Venom 400 was turned on is the biggest change. Plus you get a cool L.E.D!!

Example of what i'm talking about when i say "shift points"(might not be the technical terms): In the saturn when your driving normally without getting on the gas you normally shift once you get to about 3200-3500rpm. Then once you floor it you go to redline and shift. With the Venom 400 you stay in gear longer on normal driving. So you'll go to 4300 in 2nd gear and the car won't shift till it gets to about 4700-5000 on just normal everyday driving. Good for those 2nd gear drop in the city when racing. Instead of stomping on the gas and starting at 2200 rpm, your set to go in a more "race ready rpm range"

Anybody else have a Venom 400 that can vouch for this??

 

http://www.performanceprobe.co...0.htm

Here is where someone is explaining the installation of the venom 400 on a probe. Read the part where he says "high revs is annoying"

What the guy doesn't realise is this isn't meant for everday driving, that's why you can turn it off!!!!!!

They don't like it at this forum either but look at [Greg_04-SRT4]'s post which is the third post. He says for an auto tranny it changs shift points. check it out ------------&gt; http://www.srtforums.com/forum...31301

here one where they say 23 horses at 60mph on an F150. 5th post down by signmaster http://www.f150online.com/foru....html
