Default Speed Chip On Ebay

Speed Chip On Ebay I was on Ebay today and seen this. Does anybody know the value of the resistor used. I have a bunch of resistors in the garage. Does this actually work?

For less than $5 ($7 shipped) I can press the throttle down further and accomplish the same thing. I believe the PCM basically ignores this sensor (and the fuel map) somewhere around 80% throttle and above, it then just keeps dumping all the fuel it can muster. All this thing will do (if anything) is decrease your gas mileage at lower throttle levels. It sure isn't going to increase hp by 10-20 as hp/tq are measured at WOT (i.e. maximum fuel delivery).

you'll do all that for me for 7 bucks shipped! In 49 states, Sorry Tennessee!

s0_lo check the search in the forums. young grass hopper those questions have already been asked tons of times. Search for the answers there.

Yeah those things have been discussed before on here. I remember reading one not more than 1-2 weeks ago. So does anyone know the value of the resistor used like he asked? That would be cool to just try it out in your car some day for the $0.03 it actually costs.

I used the search. Finally fiqured out how to use it. Does n/a stand natural asiparted engine or stock?

Yep.

NA or n/a = naturally aspirated
FI = forced induction
TC = turbocharged
SC = supercharged

There used to be a big long list of acronyms somewhere titled something like "Tech speak deciphered" or something like that.

Since when is leaning out the fuel good for boost? That is new to me. Why would you want your engine to think it's 240 degrees?

Can you read? It says the leaning is GOOD FOR N/A. the timing retard is good for boost, less chance of pre-ignition. the leaning wont be good for boost, but you arent relying on the stock fuel bits anyhow, when you are boosting.

If the pcm reads the engine as being very hot, it will lean out the mixture, which is good for n/a. saturns run PIG rich from the factory, not exactly optimal for making power n/a. They run at under 12:1. Mine ran about 11.4:1, not exactly great for power!

Also, if you are relying on the stock fuel system, alone under boost, you are going to have many more issues than just your resistor mod. lol snapped rod anyone? lol

Kid, I can read fine and dandy! You must not be able too however since the topic of the post is a question about a resistor mod for a N/A engine, not a boost application.

To clarify, the topic didn't specify the application. Also, TSK's quote was pulled from another post.

Let's not drag this thread out into a pissing contest. This kind of crap ruins the forum.

2,700 ohms is typical. This will tell the computer it is between 30 and 40 degrees F. Which is ideal for performance. Anything with a higher resistance would yield even colder temps, and just waste fuel. If the outside temp isn't above 40 or so anyway, you wouldn't even notice a difference.

Additionally these resistor mods have absolutely no effect on boost or supercharged applications which is why it is safe to assume here that it is a N/A engine in question.

I am in agreement with most everyone that these resistor mods are a waste of money however and am not endorsing them in anyway.

haha youre an idiot! stay away from your car! the lower the resistance=the higher the tempurature! The higher the temp, the leaner the mixture.

You WILL benefit from this on a boosted engine, especially if you are having detonation problems. A member at tsn monitored his timing advance curve on a tec2 and found that making the engine think its at 240*, via a .02$ resistor, retarded the timing curve by 4*. It worked for me, but my charge temps were WAY too hot to quench all the detonation. It did however make a BIG difference.

If you are NOT having any detonation issues, doing this will just increase your egt's.
But agreed on the point, it is pointless on an n/a engine.

i also think these are crap, but what resistor in the ects would make the air/fuel ratio be in the area of 14.7.1?

why would you want it there anyway?

you cant modify it athat much, theres no way.

i want to run it around there, since alot of people say it runs rich already, plus i usually don't race mine, but if i were to, i would just take the resistor off.

Saturn Kid, Thank you once again for insulting me. I appreciate it. Too bad you have such a perceived influence on a forum like this, it doesn't say too much about the Saturn community. However since I am not a kid, I know better than this.

When referring to colder temps in my posts, I was referring to simulated outside air temps, not internal engine temps in which case my post was correct. Thank you for pointing out my unclarity, this is exactly what this forum needs is someone to go over everyones posts and analyze them for mistakes and then insult them at every opportunity.

Fortunately, for me my Saturn is just a daily transportation vehicle like most people, and my Twin Turbo which is what I play with (not my saturn) suffers from no pre-detonation, because I am smart enough to know that gapping down the spark plugs a few thousands will prevent this problem, rather then adjusting timing and loosing peak hp.

You are welcome. Im glad you arent a kid. Someone with all of 8 posts questioning something to be proven to work, doesnt say much for the latest rash of newbies. Yes, Im an ass hole, I know this.

You honestly think that wasnt exactly what I tried first? ha, besides running 2 step colder plugs, I also had them gapped all the way down to .30 Problems were still showing up. Modding the ECTS sensor, exactly as how I described took car of about 90% of it, with the remaining detonation being above 6200 RPM. Not really a problem, but an intercooler would have most likely solved this. But, considering the stupid setup was only putting down 160 horse at the wheels, it wasnt my cup of tea. Grossly underpowered, the blower was about maxed out at 8 psi.

We arent even talking about ambient air temps. We are talking about the engine tempurature. And even such, the IAT read the EXACT same way the ECTS does, lower resistance=higher temps.

The IAT "mods" have been proven repeatedly not to work, the best you can do is make it run pig rich, over what it already is. You dont want that, especially in a saturn!

The ects mod, VERY MUCH SO, worked for me. The benefit you would see n/a is not really going to be there though, as the timing retard would hurt n/a power and even boosted power. But the leaning of the fuel trim, will help it.

Its a toss up, nothing, including speed, is cheap....


And as to the 14.7:1 thing, max n/a power is made around 12.5:1. You woont be able to make it that lean with what we are speaking of, you will need a map modifier.
