I need diagram to change de air/fuel ratio for Mitsubishi Eclipse GS 97 I think that made with a resistance but I don't know more.

Scuse for my poor english

why do you need to change your a/f? if this is for tuning purposes on an upgraded fuel system you need a SAFC/SAFC II. you change a/f ratios electronically by using the aforementioned SAFC or other similar device by changing the MAP sensor voltage..you dont need to mess with your IAT.

i see your name seems to be french (or the like) so im wondering if your from canada or from france. if your from EU then youll have a diff motor than our 420a's and we can redirect you to a better site

I'm from Quebec, Canada, and I have a 420a motor, Somebody say to me that I can the voltage from de sensor with juste a resistance but I don't konow how I can do this.

Go see that's item on ebay, I would like to know what's that and I know there is a resistance.

that thing is garbage, i bought one a long time ago, i didnt notice any type of difference, all it does is change the temperature to like 32 degrees or something like that

Don't buy that. It's worthless.

Although you can change your AFR and timing by messing with the resistance of that sensor, it would need to be similar to an AFC or something (changing the resistance from stock over a range of RPM, MAP, actual air temp) otherwise you could seriously break things. Imagine if the resistor made the ECU think the outside temp was at 32F. You're now in death valley or somewhere really hot where it's easy to detonate and the ECU's timing curve is really advanced thinking it's 32F out. Not good.

if that all u wanna do... then youll need 2 things
1: a palm pilot w/ data logger /or similar software for monitoring
2: a vairiable resistor ( volume knob )(radioshack 5.99 usd)

cut the map sensor return wire ( middle wire black w/ yellow)
and wire the resistor inline (using the 2 wires u just cut)

hook up the palm to your com port (obd2 port driverside under the dash)

start the car and play with the knob for desired results.


or

get a pair of adjustable cam gears and adjust for desired richness


or just but an AFC

02:19:28pm InFiNiT3> lol no shit
02:19:39pm DarkOne> and a funnel.
02:19:45pm grain> have to get the ky with warming
02:20:00pm InFiNiT3> i feel sorry for the 18 y/o (one was 17 one 18) his name was plaster'd all over the news n news paper
02:20:06pm DarkOne> Yeah, has to be warming.
02:20:06pm BuckNutty> jus spit on it and it'll go in
02:20:17pm InFiNiT3> aye the ky w/ warming any good>
02:20:45pm grain> never tryed it
02:20:50pm grain> i applyed for a sample on thier website
02:20:56pm BuckNutty> evan didn't complain any
02:20:56pm BuckNutty> it felt nice
02:20:57pm InFiNiT3> lol
02:21:01pm grain> i use id glide whne she dries
02:21:06pm grain> good stuff
02:21:45pm InFiNiT3> thnx for the new sig guys
02:21:45pm DarkOne> Are we still talking about fucking dead chicks?

That probably won't work... The stock ECU switches the bias resistor of the intake sensor on it's own in order to improve precision over a large range of tempatures.
