yeah, it was probably just my tranny's time... i am almost positive you will feel some more power. my guees is about an added 10hp or so. but you can get the same effect by advancing your timing. my uncle did it to his 88 chevy astro cargo van, it had its power problems(or so i thought, keep reading) so he got the timing advanced. a lot more power but after about a half hour of driving, the engine would start acting funny so he pulled over. it flooded. so he did that for about 2 weeks then had it set back. then i found out he was using his van, overloaded its hauling capacity by about double and was using OVERDRIVE. i told him he needed to put it in drive so it stayed in 4th going up the hills or even 3rd if the computer felt needed. here we were chugging up the hill in overdrive and it rarely downshifted when it was in OD so that was the problem. he told me that having it in drive felt to powerful so he didnt use it. well having it overloaded by double in the first place is dumb but leaving it in OD the whole time.....jeez. also the tires, all 4 had the metal showing and he would purposely hit already dead roadkill which is a good way to get a flat....yeah...thats my uncle...too many BYOM parties. yes i said BYOM...Bring Your Own Marijuana....NOT KIDDING EITHER

 

Oh my, I can't believe all the money I spent in a quest for more power and I didn't believe the add on ebay. Foolish foolish me. lol

Some folks obviously have no idea how a PCM works or any of the sensors associated with it. You can temporarily fool the PCM in to believing the intake air is colder than it is. It will adjust the AF mixture accordingly and then when this faulty mixture gets to the 02 sensor its all over with. The PCM will countine adjusting until it figures out the inlet temp is wrong and throws a check engine light for the sensor being bad. It will the run the engine off of the info coming from the MAF and the 02 sensors. So now someone is probably thinking 'duh i'll just get rid of the 02 sensors'. Honestly if you hate your truck this much just drive in to a swamp. As has been stated if you can afford real mods you certainly can't afford broken s*^t on your truck now.
Horsepower cost money!!!!

 

but do YOU have any data showing it doesnt work.
have YOU personally tried it.

yall dont know if it will or wont work because noone has tried it. you assume because its from ebay that its a pos. (which it may be)

i dont have a problem trying it out. if it hurts my truck and repairs are needed ill asses the situation when the time comes. i appreciate the input giving but i feel like yall have no known evidence backing it up. seeing as noone has actually given it a try, theres no proof to it not working.
if it doesnt work, you can say i told you so.

now i understand that it is just some cheap item off ebay but it may give me a bit of a gain with no problems at all for the life of my truck. IF thats the case, then i believe i spent 25 bucks well. if not, ill have costly repairs to make.

 

yeah he means if the resistor does end up messing it up, while he is replacing it, might as well upgrade.

but wouldnt his reply be...i cant hold yers, my hands got 2 of my own.

 

" ... and this here diode ( resistor, actually), is why, Johhny, I couldn't send ya off to College, on account of the engine done blowed up and I spent all yer school funds fixin' it ....."

 

 

if im shown real data that prooves this wont work at all or that shows itll hurt me.

itll go in the trash as soon as i get it.

 

thats another thing, my check engine light never came on. i had that chip in for about a year. well it came on after the valve burned but that was 6 months in. i am pretty sure the MAS going bad didnt throw a code tho....but hey it was 8 years ago.

 

or maybe i could use it as a paper weight... lol
i know theres someone on craigslist or something stupider than i am that'll buy it from me.

 

I do not think this is the case ...

IF the sensor was SHORTED or OPEN, then the PCM can detect a faulty unit and run in limp-home mode with a CEL.

Otherwise, if it is giving any resistance reading at all within a very wide bound ( as the truck can run in either Arctic or Sahara-like conditions), then the PCM ha NO OTHER WAY of knowing what actual ambient is. It is the ONLY temp input the PCM has - so it MUST be accurate.

 

hey, just noticed you already have a cold air intake. just letting you know that the chip does the same thing as a CAI except without actually having one. the chip tricks your computer into thinking it works, your intake actually works. sorry for not catching that before...so with that info, you will probably get no power or actually lose a little. by the way, do you have an open filter or closed filter for your CAI? because either way i can suggest something to help out a little.

 

well crap.
lol

its an open filter
its a spectra cold air from auto zone

what you got for me?

 

Isn't that what I said? Check engine on and the only source of info the pcm will have to keep the engine running is the maf and 02's.

 

No, this is the diode be buys after he finds out the resistor didn't do anything. He read an add that said, the diode doubles the results of the resistor.

 

I doubt it.

Use the search feature here. There has been many discussions about these items, how they work and the potential damage caused. If you want to ignore all the warnings go ahead but the repairs are going to cost you a lot more that the 25 bucks you have wasted on a 10 cent resistor. There are web sites that show you how to wire in the 10 cent resistor and save yourself $24.90. Do some research and listen to peoples' advice. I do not have to try jumping off the Empire State building to know it is bad for me.
