RE: venom 400 control module question

I look at them the same as I look at S-AFC's and V-AFC's, they are junk by way of tuning. Timing is the key, fuel and air are very important but timing is what keeps engines together even in adverse conditions.

The Venom 400 activates at about 25-30% Throttle Angle. When it does it modifies the input signals going into your computer, in particular the Manifold Absolute Pressure and Throttle Position Sensor Signals.

Well, when the computer sees these "modified" signals it will provide a different set of fuel and ignition maps than it would normally provide. These maps tell the computer what the spark timing and fuel injection pulse (fuel) should be for any given engine operating condition, like under load, part throttle or deceleration. The Venom makes the computer use different maps that are more aggressive and provide better performance

^Sounds like a band-aid, why trick the sensors when you can just outright change what they are supposed to or what you want them to do with chipping a ecu with say crome pro, uberdata, turbo edit, so on and so forth.

Quote:

Well, the factory ECUs are not always tuned for the best performance, they are tuned for the best fuel economy and emissions. That's particularly true of sport compact cars that are designed to get good fuel economy.

^Not to true, with honda's B, H, F, and D series engines they are tuned from the factory great for N/A setups, this is why you do not see hardly any gain from bolt-ons and tuning because the ecu's are setup in a manner that naturally aspirated unless you do high compression, ITB's, agressive cams then the ecu can cope with it for the most part. Hell I see 75 shot n2o kits going on civic's with absolutly no management and not hurt the car at all.

What I am saying is that for the setup in question, get a stock ecu(P28/P30) then when time comes to actually need to tune it you have the ecu to get chipped with a real fuel management source not some cheap-o piggy back crap.
