Fuel saving module/ebay??

[andrewjetmitchell]

Anybody tried these? Have Pics? Says it leans out the fuel system? and the $5.50 speed chip? 20 hp? Jet

a lot of ebay "fuel saving modules" are nothing more than a resistor which sends a signal back to the ECU saying that the air is 58 degrees... (or some set temperature)

my question to you is this: If infiniti after millions of dollars of R&D didn't feel like this was a good idea to have on your car, do you think you should risk the possible side effects it may have for you in the future?

Don't worry about fuel consumption too much, driving style is going to do more for you than anything else.

I don't trust ebay. I would only get brand name stuff on my car. Maybe if I had a Honda or a cheaper car I might.

Caveat Emptor (let the buyer beware): I spoke with the developer of one of these little gizmos.... one that modifies the ECU slightly (done via computer and not a so called chip) to increase horsepower. After much questioning he informed that they had fried several engines when the fuel mixture was modified outside of the parameters designed for the engine. Interestingly, they continued to sell the product despite these findings.

The big question would thus be, if yours also fried, who would pay for the repairs? Not them, it comes with no warranty of this sort.

Fuel saving gizmo's & do dads have been around & sold to the gullible for over 50 years. You want to increase your mileage, buy a Prius.

find out what ohm resistor they are selling and go to an electronics shop and buy it for 30 cents...

better yet, fill it up with "regular" and then park it in your driveway for one week...you'll be amazed how much gas you save that week!!!

(just kidding...)

I have had this mod on my jeep now for a year, with great results. On the Jeeps you just unscrew the AIT sensor and move it to the stock air box so it measures the colder air temp coming into the air cleaner rather than the heated up air in the intake. or leaning out the fuel system. All it is doing is fooling the computer that the air temp is lower than what it really is. If that would fry the engine then it would do the same on a cold day, and it got down to 25 degrees here last week. I really wanted someones input that already had it on there G. anybody??

What the company rep informed of was that the mod was much more effective on trucks, jeeps and vehicles where engine inefficiency was lower. He was only clear that the engine frying had occurred in higher performance cars, especially Japanese ones such as Infiniti, Lexus and Acura. The engine frying did not occur on all engines, but there had been a small number with engine problems. The risk was mine should I opt to put the piece in. Given this info, I'd rather take my chances and not grab fr the Holy Grail of power--- 5-10 more hp. If 5 folks here have done it successfully, I still wouldn't risk it.

It is an expensive luxary car. I wouldn't risk the engine for a cheap ebay product that seems too good to be true. It's like all cars of it's class, Parts that are worth wild are going to come at a premium.

The VQ35 engine is a high output v6 that is very efficent and out perfroms many v8s of much higher displacment. My car has beaten plenty of 5.0 mustangs. You pay for that performance with not the greatest v6 gas milage. I had a supercharged 3.8 buick regal that got beter gas milage, but that car wasen't as fast as the G35. Just upgrade your intake or atleast the air filter.
