Timing Advance Kit DIY Tutorialm - Track Results Update

[Fishboy55]

This thing has been discussed numerous times. I'm going to try to finally put it to rest with some FACTUAL information. This is based on the theory of how the intake air temperature sensor (IAT) works in our cars. This is something I am knowledgeable about and have proven by actual installation.

First: What this guy is selling on Ebay is a ten cent resistor that you can purchase at Radio Shack or any other electronics store. Don't buy it, as I will tell you how to make your own and hook it up for free.

What it Does: The IAT measure the temperature of the incoming air through the MAS and adjusts the timing accordingly. What the seller is telling you is factual. If the ECU thinks you have colder air coming in, it will advance the timing accordingly. Will this result in a 20 HP gain?? Hell No!! Will it increase your performance? Yes, probably, and I'll prove it at the track next weekend.

According to the Service Manual for the 8G, the values of resistance based on inbound air temperature are as follows:
0.30 - 0.42 K Ohms = 170 degrees
1.0 - 1.5 K Ohms = 104 degrees
2.3 - 3.0 K Ohms = 68 degrees
5.3 - 6.7 K Ohms = 32 degrees
So as the temperature of the inbound air decreases, the resistance of the IAT increases and sends a signal to the ECU to advance the timing. Maximum advance is roughly 3-4 degrees.

How you can make your own: Go to the Radio Shack and get a 1/4 watt 3.3K Ohm resistor. The color bands should be orange, orange, red, gold. The last band is the tolerance of the resistor, with gold being the best, silver a little less. Now referring to the above chart, a 3.3 K Ohm resistor will equate to an inbound air temperature of somewhere around 60 degrees. I wouldn't recommend going any lower than this. Just my suggestion.

How to install it: The IAT is inside the MAS and uses two pins on the MAS connector plug. The objective is to put a resistor across the IAT and let it assume that the inbound air is always about 60 degrees. The IAT uses pins 5 and 6 of the MAS connector. Refer to the following diagram:
http://us.f1.yahoofs.com/users/4f4e72d4/bc/Yahoo!+Photo+Album/IAT.jpg?bcxFBd9A_Xq38S5A
The best way I found to install the resistor is as follows:
1) Unplug the MAS connector and your negative battery cable.
2) Using a pair of wire strippers, gently pull the insulation back off of the wires in pins 5 and 6 They are the black wire and the red wire with the blue stripe. Your objective is to expose the wire, not cut it.
3) Once you've got some copper exposed, take the resistor and wrap one end around the exposed part of each wire. Polarity of the resistor isn't important. In other words it doesn't matter which end goes to which wire. Crimp it tight with a pair of needlenose so it makes a good connection.
4) Seal each connection with either a drop of silicone, like I did or with electrical tape. Whatever you choose, just make sure the two wires dont touch each other.
5) Plug the MAS connector back in and connect your battery back up. Start the car. Your ECU will reset and you may notice your engine revving higher for a few seconds. No SES lights should stay on and you shouldn't notice any other changes if you did everything right.
6) That's it!! You've just told your ECU that the incoming air is always about 60 degrees, despite what it really is. You may notice some increased pickup and throttle response. As I said earlier, I'll confirm the real effect of the change at the track with my ET.
7) I've had this installed for about two weeks and have not noticed any adverse effects at all. Since I don't race on the street, I can't honestly tell if it makes a difference. In normal highway driving, the car seems more responsive, but that may be psychological.

Please note: This change and pin configuration refers to the 8G IAT sensor only. I don't have a pin out for any other versions, so I'm not sure what the pin configuration is. The theory and installation will be the same if you find the IAT wires on an earlier generation wiring diagram.

Install this mod at your own risk I (Chip) and TGC take no responsibility for any damage you cause to your vehicle.

I like the tutorial. Good Job Fishboy. When do you expect to go to the track again.

[EsRacer]

Good shit guy! I was ready to buy this 10 cent mod for $6! Good thing i posted and real brothas like you come out and expose the real shit. Well imma go down to Radio Shack my next available day and do this mod. BTW good job on the tutorial!!!

[burthold]

Exelent writeup. have you done this mod to your car? If so, does it really help power that much? Any additional info you can give would be nice.

Thanks!

Wes

[Big H Killa]

Fishboy said he would tell you if he has any increase when he comes back from the track next time he goes.

[Fishboy55]

Thanks everyone. I'm just trying to provide accurate info instead of opinions and bullshit. That's what this board is for. Yes, I did this to my car Wes, using a 3.3K Ohm resistor. No adverse affects. Been installed for about two weeks.

Big HKiller: I'm heading to the track on Friday night. We'll see if I get the 20 HP gain that Ebay thief is claiming....NOT!!!! https://www.thegalantcenter.org/style_emoticons/default/laugh.gif

Chip

[Big H Killa]

If you get any gain at all then it's worth it.

[NRG]

Damn, now I wanna go down to Radio Shack.....!! https://www.thegalantcenter.org/style_emoticons/default/laugh.gif But I am afraid I might cut the wire instead of stripping it.......

[99DE]

This does work. This used to be a secret mod for my friends Sentra SE-R club years ago. And it was noticeable, the only downside at that time was because your car thinks it's colder it uses more fuel to try and heat up, so it eats up the fuel tank. I think I'm going to try this also on my Galant. Thanks for the Instruction https://www.thegalantcenter.org/style_emoticons/default/tongue.gif

[NRG]

Do you strip the wires on the plug or is this wire inside the MAS?

[TJC]

<div class='quotetop'>QUOTE(NRG)</div><div class='quotemain'>Do you strip the wires on the plug or is this wire inside the MAS?</div>

I'm pretty sure Chip was refering to the plug. I don't think you can get to the wires inside. Heard someone that did this rigged up a switch from inside the car so they don't have it contantly tricking the system.

[Fishboy55]

Yep, the two wires I referenced are in the MAS plug.

[Black2k1GTZ]

This sounds like a good idea...but one thing came to mind when I read this. If the computer thinks there is colder more dense air coming in to the engine...it will compensate with added amounts of fuel...but if the air isnt there...then wont it be over fueling??????

This is almost exaclty what i asked you guys about that I used to do with my probe here's the link I gave http://rogue.bucks.edu/~0257335/IAT/ ('http://rogue.bucks.edu/~0257335/IAT/') thanks

We tried telling these guys about it before, Now there must be a way to hook up a switch like we did, I'll check into it....

[Los]

Hey chip ,....great work on this tutorial. If I don't make to the track with ya'll this weekend let me know how it works out.

[wmaharrisjr]

i did mine last night and definitely noticed a little more low end kick in the pants and sometimes if i get that perfect take off it will "push" you into second

[J. T. Z.]

WOW! Great research Chip! I wish there was a way to post this right along side all of that guys items on EBAY.

true.

Chip, thanks for the research and posting your findings. At least the resistor is a relatively inexpensive mod to test, hehe.

ROCK ON! I love it when people come through. SO you pull a flat 6 on a sportty tree? that is mighty impressive.

<div class='quotetop'>QUOTE(Fishboy55)</div><div class='quotemain'><div class='quotetop'>QUOTE</div><div class='quotemain'>
As for adding a switch, I would think you have the circuit open when you don't want the resistor working and shorting pins 5 & 6 with the resistor and switch inline in between the two wires.</div>

OK Help me out, it's been too many years since Electronics training. It will have to be a DPDT switch because there's two wires, but I can't for the life of me figure out how to make it work. I though of just putting a potentiometer in line with 5 & 6 to vary the resistance, but I think a straight on/off would be better. Anybody??

Thanks,
Chip</div>

you cuold use a spdt relay and switch or just run a on/off switch directly to some lead wires that you splice in to interecpt the jump resistor between pins 5&6. running a spdt relay would shorten the circuit's wire run by openning and closing the new circuit locally but would involve a seperate power source to operate the relay.

Wes</div>Well thanks Wes. Actually, on my last run of the night I pulled a .599. First time ever in the 5's I was pretty excited. Still lost though. The other guy had a 3 second head start and until I get my FPR, I don't have enough top end to catch him. Oh well....next time.

TJC thanks for the link and yes it doesn't make any sence in adding this product on our machines.

[Auto-9]

<div class='quotetop'>QUOTE(TJC)</div><div class='quotemain'>isn't the optimal Air/Fuel ratio something like 17:1 respectively?</div>

Honestly I don't know...I was told that gasoline engines like a ratio of 14.7:1 but it could be 20:1 for all I know.

[galant2kde]

are there any other cheap shit that u can get a wire ur self from like radio shack to fol ur ecu to add gains to the car and making in faster?

[2001SCREAMER]

The only problem with this is that if you put a 3.3 across those wires the ecu will not see that 3.3 because you will be parallel to the air temp sensor and what you will have is a resistance of both devided so the ecu will see like 1.6 or so not 3.3. Just something to think about you would have to unhook the one in the mass. Because if you don't the value will be to low.

But if you hooked it inline say cut 5 and put it between than you would add the resistance that you wanted. So if at 104 you have 1.0-1.5 ohms than you would want to add 1.5-2.0 ohms to fool the ecu into thinking that cooler air is coming in, This way air intake sensor is still operational.
but you get the idea.

[galant2kde]

2001screamer can u deal tail that a little i think i would have a way to by pass with a switch from inside the cabin if u wanted to run on the resistor or if u wanted to run with out it like an on and off thing only if u needed to race, and i have a 3.3 is that the resistor u wanna use? get back to me and if ur right ill draw up some plans hit the track and inform all you...aigh get back to me thanks for the info

Good luck! :? I guess, lol.

[galant2kde]

thanks man, but only if i get more info from screammer than i could wire shit up nice i work good with like electronics and shit and ill hook u guys up ill test it if i get some good gains i will deff. hook u guys up...

[galant2kde]

ok i have figured it out but it might be a lil compilcated k... im gonna post a pic... its a plan thanks ill let u know whats up...

Go here to see a diagram of how the resistor should be hooked up. This way even when it's below 60 you won't have a prob. Because the IAS
is still controlling everything, the ecu just thinks it's a little colder than actual outside temp, no matter what temp it is outside.

[LantBoy99]

alright alright, hold up here......let the electrician up in here :twisted: So you wanna hook up a switch to this thing right? I myself havent looked under my engine for this mod yet so I have really no clue where this is located or how I could put a switch too it. Being a commercial/residential electrician I dont have much knowledge of the DC 12V current compared to the AC currents. Both are pretty similiar though so ill take a shot at this.

If you wanna hook this thing up to a switch your gonna need your power,switch leg (the wire going to the thing that you wanna make it switch), and a ground. Youll need a wire going to that thing that you want to be switched and a wire going to your battery (make sure you put a fuse somewhere in there on the power wire) you dont wanna burn up ur MAS or whatever. For the ground wire just make sure youve got a nice secure ground. Before hooking up a switch I would disconnect your battery. Even though 12V just tickles me when im shocked since I been shocked by a 100 AMP service panel that knocked me down. So you shouldnt kill yourself doin this. Be careful though please. I think this might answer your guys question on switching this thing if not then let me know and ill try to help in whatever way possible. If anyone ever has any electrical questions please feel free too PM me.

[2001SCREAMER]

I have created a switch diagram and will post as soon as I can upload it. If you'd like a can email it to you. email me at [email protected]

[2001SCREAMER]

Yea I know it doesn't work, thats exactly why I've never done it I was just haveing some fun with the ones that try this shit. If you want to alter the timing by a timing controler and afc. Yea your right I can't believe it ever got this far either, but as you can see there lots of young gullable
kids out there that would actually cut wires off the mas to see if this works.

:firedevil:</div>So let me get this straight. I do a lot of research, alter my car and post real results in response to the flood of questions about this scam on ebay. You come on and lead ppl to believe that it WILL work if they wire it up your way, and you knew it doesn't work?? So it was a joke? Ummmm maybe I'm wrong, but if one of these "young gullible kids" were to follow your diagram and wire something wrong and ruin his MAF or worse his ECU, that would be funny to you? That's pretty sick , man. People come here to get information and learn, not to be toyed with and risk damaging their cars as a joke. There's enough misinformation on here unintentionally without the need to dispense BS on purpose. Think before you play a joke like that dude. You could wind up with a lot people pissed at you, or worse at TGC. Just MHO.

Chip

[2001SCREAMER]

Wow hold on now. I would never give info that would mess any ones car up. I just gave info on how to do it the right way so they would not mess there car up. I don't want these people to mess there car up or anything.
But wouldn't you rather they know a way that is reversible to try this without messing up thier car. The ones that want to try this are going to do it wether I tell them how to do it or not. I'm just trying to look out for everyone.

[galant2kde]

screamer first off ur diagram sucked when i did wire it that way to get resaluts your engine stalls the hell out and u cant start it with out the resistor not being there dude think b4 u talk fishboys right i mean if u give out some false info and i tried it casue i beleived u then dude would i ever be pissed off id hunt u down the second my car got messed up...

ps. note to self unsubscribe from this thread.

and yo fishboy i give u all the credit in the world for going what u went thru to figure this shit out and saving people from buyin false products online that could damage ur car... A+ man keep up the good work...
