Mike T

Ok I was talking to a guy who knows alot about engines and here is what he told me about programmers and superchips

also note that all those chips do is alter the signal of the throttle position sensor to have the engine thing your putting your foot farther down on the gas. eg if your at 25% throttle the chip may tell your ecu that your at 35% or so...its fake hp it doesnt do anything in reality but fool you.

Is this true

tell him to take his foot out of his mouth- see post- IS a chip worth it?

Sounds like your friend doesn't really know that much about Superchips and how they really do add HP to an engine. How? Well, I'll defer to Mike Troyer who is the resident expert in this area. He's under the weather right now but he'll be around soon to set your friend straight.

In the meantime, run a search on this website to educate yourself and your friend on exactly how people feel about their Superchips and Superchip tuners.

Once you install one you'll wonder why you didn't put one in earlier.

I have to say that this is the funniest thing I have read in a longggg Time.

Your friend is talking out of his ****.

I have heard of so-called "chips" being sold that are nothing more than a resistor. (85 cents @ Radio Shack) These do nothing more than drop the voltage, that the CPU "sees" from the MAF sensor.

This "tricks" the CPU into adding more fuel to the mixture as the lower voltage indicates cooler, denser air entering the intake.

The result is very little, if any, power gained and alot of gas wasted.

Essentially (Mike may chime in at some point and correct me, but this is my understanding), since these trucks are almost entirely computer controlled, the PCM obviously is in charge of timing, camshaft advance, etc.

The Superchip steps in by providing a "Piggyback" unit (in the case of the module) or by providing an economical "reflash" (Microtuner, with the ability to reflash back to stock). The actual change it provides (specifically the programs contained in the units) is by allowing the engine to advance timing well beyond what it would normally be, because it calls for the use of premium fuel. The program also allows for the addition of more fuel to compensate for the extra power generated. Whenever timing is advanced to the threshold of predetonation (but NEVER going over, especially in high-rpm situations), max power will most often be seen.

By rounding off the tune with more line pressure in the transmission during shifts (and the removal of various timing retarding during the shifts), the chip is able to deliver more power to the wheels than without transmission tuning.

Superchips, if I'm not mistaken, still take the exact same Air temp, flow and TPS readings that the stock program requires, and they stay within allowable range of O2 sensor output as well, making them Emissions certified.

He is sticking to his story???? If I where you, I wouldn't let that guy change my oil, much less work on anything mechanical.

Ask this "expert" if he knows how one would tune a carbuerated engine? Then ask him if one might be able to tune a fuel injected electronically controlled motor by adjusting some of the same parameters.

I am beginning to think this guy does'nt exist. Are you pulling our legs in an attempt to get someone worked up??? I can't believe anyone who knows anything at all about the internal combustion motor, would not know about timing and fuel ratios.

V8SilverSTX,

What is the last engine that this guy worked on? One that starts with a crank?
Obviously this individual doesn't know a lot about engines?
What the PCM, Powertrain Control Module, does is take sensor input, use look up tables to convert the input to required out put, and perform the out put. What chips do is change the out put by modifying the look up tables. One of the outputs is Injector pulse width. This is the amount of time that the injector remains open. What a chip does is change the look up table for pulse width for a given set of input criteria. As suggested do not let this person work on your vehicle.

Regards
