+20 hp Timing advance mod on Ebay---> Experience Please!!!

[NiSmO_zt]

I was browsing on ebay and came across 3 or 4 of these ads for selling a +20 hp mod that adds a resistor to your mass air flow sensor and advances the timing for more power. Has anyone done this? is it recommended? It would seem as if you could just put a resistor inline with the signal wire on the mas, or for temporary use, use a toggle switch to switch between the normal circuit or the resistor circuit

anyone with this mod or info about it please elaborate
here are teh urls for the ebay auctions

thanks for the help

If you've never heard about it before and it's sold on ebay cheaper than you think it would be worth if it worked then it's probably pure crap.

If it did actually work you would probably have to buy premium gas to see the performance gains just like ecu chips. Premium around here is a few cents short of 2 dollars a gallon so it would be a waste imo.

[badicalradical]

premium is 220 here and i have no experience w/ what your talking about

I agree with the others. You get what you pay for. If you get it cheap, then its probably cheap.

On the lighter side, why dont you go and buy it, install it, then post a thread telling us what you experienced. Just a suggestion.

whoever doesnt know what that is is a complete

its a transistor that plugs into the maf sensor that advances timing


it works on cars that don't have a cold air intake. i know because i used it.

go to radioshack and buy a pack of 10 transistors for .99

It would help if you gave a bit more info about which transistor as there are literally hundreds of different ones at RS alone. Why would you use a transistor anyway and which of the 3 legs would connect where? What's the use of having it being able to switch when you want to use it all the time? And lastly, will a resistor work in place of the trans?

I personally wouldn't do this to any car I own...if I want power I'll get more than 20 from a swap or from bolt ons and that 20 will be useless once I have reached my hp ceiling.

[mynismo]

i doesnt give you 20, thats a complete lie. it gives you around 5hp.

it does work.. and very cheap and easy.

there's really only one kind of transistor out there. the cheap one. unplug you maf and stick one end into each opening.

it tells the computer it's 62 degrees or something like that.

why not, just advance the timing the old fashioned way.... turn the distributor a bit?

If this is a MAF function, it likely tricks the ECU into thinking that there is less air coming in than what you really have... Therefore the ECu interpolates from its map that the TPS is set at a certain load point, and the MAF is telling it how much air is there.

In effect the ECU will then lean the air/fuel mixture, since our O2 sensors are total junk and and the ecu has decided not to listen to them anymore... the burn will be leaner, getting you closer to stoich, thus giving you slightly more HP.

after reading the description on Ebay, my assumptions are correct, If you really want to tune... just buy an aftermarket ecu, more cash, but much much safer, with more obtainible HP out there than just a claimed "12-20"

that is exactly what it does, the resistor (NOT TRANSISTOR) resists the electricity flowing thru the MAFS wires, making it seem as if the MAFS is telling the ECU that air is low, all because the resistor holds back the amperage running thru the wires to make it seem lower.

this item should be on motor millions crap cause it gets so many people. my dad has a kajillion resistors and chips downstairs, he was an electrical engineer for 35 years, ill go build my own goddamn ECU before i just slap on a tiny little ceramic resistor.

I suggest you dont do the mod because you will run lean. Posibly burning up valves, frying spark plugs, and lean means more heat so if it gets out of hand you could even melt down your pistons. The list goes on and on, need I say more.

[lecksikon1974]

You're all on the right track, I am probably one of the most succesful sellers of this product on Ebay it made a Powerseller out of me instantly.

It really does work,

The resistor sends a constant optimum signal back through the Inlet Air Temperature sensor connector to the ECU. This signal indicates the Air Temp is 0 Degrees which in turn makes the ECU respond to the anticipated Air density by advancing the timing and slightly enriching the fuel mix to create the bigger bang. These things are cheap but Very effective if you just want to squeeze a few extra BHP out of your motor.

Watch out though, most don't offer money back like me, and they'll even tell you it works on a Turbo-charged engine (It won't)

I hope some of you can put aside your doubts long enough to try one for yourselves and see how amazing something as simple as this can be!

Yea I basically just turned the distributor a bit, advanced it about 2-3 degrees. It works just the same. I dunno about increasing hp, basically what advancing the timing does is it makes your idle RPM a lil higher, and lets your RPM peak out higher each gear. I noticed better throttle response and I did feel a slight difference. It was a free mod also, just turn your distributor. You will have to run only premium fuel though

[nissanfanatic]

Did you guys look at the date on this thread!!!! And just so any of you new guys think about trying this, don't. It just tricks the computer by telling it the incoming air is colder and dumps more fuel in and advances timing. You would be better off running a SAFC. Come on, if 20hp was that easy to obtain, then why don't any big name companies or even small name companies sell them. *cough*BULLSHIT*cough*. I know because I tried one. No difference whatsoever. I believe my walbro fuel pump alone did more than this mod. Advance timing the old way or use a MSD advance or a BTM. I used my BTM to advance by setting the retard setting at 3degrees retard and then set my timing to 20BTDC. Now I can turn the retard setting to 1degree retard and advance timing 2degrees.

lol thanks, but I replied to that about a year ago....

lol dayna, how did you know to that I posted in here? If you haven't been in here for a long time
