Hi there,

I've been thinking about buying an Ebay chip. Been asking the sellers about the posibility of turning off the AC at WOT.

Some say that they could do it, some not. From my research I saw this IS possible with the Hondata S300 but I dont know if this ebay Socketed Ecus can do it really.

Dont want so spent 200 in something that wont give me much, since my car is a 98 EX D16Y8 stock, only an AEM SRI. And I would like not to loose fuel economy aswell. But passing on the route in my country its a bit dangerous and with the AC on, even more.


Thanks

Are you really comparing an "eBay chip" to a Hondata S300?

I'm thinking you are going to get flamed pretty hard for even making this thread.

rovafa2002

Hahah Im not comparing, just telling facts. Hondata S300 allows the AC cut out, just asking if its even true that an Ebay chip could do that aswell.

Im talking about those ECUS that claim to be compatible with S100 and S200.


Thanks

Do more research. You can't chip an OBD2 ECU.

youre better off leaving things stock. no need to *** with AC shutoff an convert to obd1 an run some random persons program. Short ram or not... its not gonna matter.

Yup.

You just broke his heart. He was hoping for extra mAd VTAK yo.

it's much better to learn the hard way. cut as many corners as you can, go ahead and buy the ebay chip.

That's where you messed up... right there.
Everything before that is fine but everything after... not so much.

spoolymcgee

Just delete the ac already, or by pass it with another belt and when you want ac put the longer belt back on.. Boom done.

This is ******* hilarious. OP, you're seriously considering spending $200 on a shitty basemap that isn't even set up for your car, when you could call Xenocron and pay less than $50 for a basemap, from a real, reputable company, that will fit your specifications exactly? And even better, if your specifications are ******* stupid, they'll tell you?

Do it the right way. Call Xenocron.

1) trying to reference an "ebay" specific chip is stupid. Most ebay seller's use Crome to program their chips, and yes it is possible to setup an a/c cutoff using Crome.

2) I'm probally the one you asked on ebay if that was possible, and I responded yes. Guess what it is possible. Don't ask the idiots on here who have probally never even tuned a car in their life time.

3) There are good sellers on ebay. Don't let the idiots tell you other wise as they have never even tuned a car let alone have any real input.

4) I know a honda-tech sponsor who sell's on ebay, but not one person would aruge with him. Point being just because a person sell's on ebay does't mean they are not trust worthy.

5) I could keep going on but I will stop... flame on b@%!?'$

Don't let anyone tell you that a basemap is comparable to a full blown unit like Hondata either. And don't let anyone try and sell you a chip or even a socketed ECU with a basemap just to get negligible power gains. For what the OP wants to do it would be absolutely stupid to go this route. Want the A/C off for a little more power when you pass? Do what my wife does, SHE TURNS IT OFF TO PASS!!! It's one friggin' button for chrissakes!!

Of course the AC off function is possible. Its been a parameter of every Honda tuning system Ive seen. If the ebay "tuner" says no that means they don't really know how or they aren't customizing the basemaps like they claim they are.

LOL. This is entertaining.

The AC cutout option would be a Plus, but I am really getting to think that there will be no Gains in power nor fuel economy (at part throttle) by doing this with my Stock setup, except for no CAT (dont have one in south america) and AEM SRI.

However I get really lost with all the coments, as well as reading through the forum. Specially when I read that many people recommend "Pheareable" and they answered me these...

1st EMAIL
"Rovafa2002,

The gains are limited with the modifications you have.
We would recommend adding a header & exhaust.

Our chipped obd1 ecus do not turn off the a/c during WOT.

Thank You,
Phearable.net Sales"


2ND EMAIL
"Rovafa2002,

You will see around 4-5 whp on that application.
For the best result you should use an aftermarket header & exhaust system.

Thank You,
Phearable.net Sales"


As a note, many people on ebay who I asked claimed not to expect more than 2 hp from my setup.

Wonder if what Phearable offers is the final tune, or its just a basemap to get it running to a Tuner ASAP.

Okay, NO ONE (at least I didn't) is saying what you want cannot be accomplished employing the method you're looking into.

You have an OBD2a vehicle. Those ECUs cannot be chipped (easily). No one does it anymore. Especially no one on eBay (ha). You would have to also purchase this "chip" already installed in an OBD1 ECU (because they CAN be chipped), or have a socketed OBD1 ECU to which you can drop your chip into, add to which you will also have to purchase an adapter harness to allow you to run that OBD1 ECU in that OBD2a vehicle, to complete the package. Then, if your "programmer" doesn't know what he's doing (which is quite common), you'll have a shitty running car. Then you're talking about a (dyno/street) tune, which you cannot do on a chip that's already burned. Your tuner would have to have the capability of not only dyno/street tuning your car, but also burning the custom map to a chip to install in your ECU. You're looking at another $300-$500 just for that service alone on top of the OBD1 ECU and adapter harness. So maybe you might get away with spending $600 ish? For what?

So tell me if all of that is worth it when you can just reach over and flick off the AC and turn it back on as you need it for free?

I just pretend the AC button is like NOS. When I need to go fast I click it and floor it. Then when I'm done, I click it back. Sometimes the NOS makes my cabin a little bit warmer, but it's worth the extra HP.

Bradshaw

why does a/c have to suck up so much power?

but seriously though, just turn off the a/c when you need to pass/get on the freeway.

unless you're doing a motor swap or turbo, don't mess with the ecu.

Oh boy. Any tune that is not done personally for your car by a tuner on a dyno (or street tune) is going to be a basemap of sorts. Lets start from the beginning.

1) What are your goals?
2) What is your budget?

Right now it looks like you goals are only to spend some money on your car. Its almost like you have a whopping $200 burning a hole in your pocket. You need to do some research my friend, but I will help you out.
Here are some basic guidelines:



PLAN PLAN PLAN PLAN PLAN PATIENCE PATIENCE PATIENCE PATIENCE PATIENCE PATIENCE

There are already too many people out there ruining their cars and WASTING money because they just can't wait to do "something" to their car, no matter how pointless it is. Please don't be another one of those people.


*First discern your power, reliability, and drivability goals.

*Next assess your budget and determine if those goals are realistic and readjust your goals if necessary. (Generally, if your budget is less than $1000, then don't do anything. There is pretty much no discernible performance to gain without spending more than a grand. There are quite a few exceptions to this, but I don't want to go into depth with that. For example: an upgraded clutch, NOS kit, and tune will get you there, but that set-up has its own issues and I would not go that route. Or, you could go with a used turbo kit/new ebay turbo kit... might get all of done and tuned for $1000, but I wouldn't do that either. Generally, you would be better off saving up until you have enough money to actually achieve some performance gains properly.)

*Next select a platform. Do some research Keep you overall goals and budget in mind.

*Next, budget out 20% extra for unforeseen costs. You, might have some left over, at the end, but that is better than not finishing your project because you did not plan correctly.

*Finally build it and drive it.


I'm only guessing, but it sounds like you just want to spend a couple hundred bucks on the car. Well, that isn't going to get you crap. If you want to keep that platform and stay NA, then the easiest set-up would be Intake, Headers, and exhaust. In these small displacement engines we have, doing an NA build requires careful planning to get every horsepower at the desired RMP range as possible. Do a lot of research and decide what combination of parts gets you the results you want. Piece the parts together over time if you do not have the money up front. Just budget and plan to do it.
Then, when you have everything, bolt it all up and take it to a shop to get dyno tuned properly instead of using some ebay basemap stuff. If you are serious about getting the most for your money, then go to a reputable tuner and tune the car. Even though some sellers have some decent base maps that will help you out, they will not be the same as an actual tune of your car. This is because every engine and combination of parts is unique and thus a car must be specifically tuned for optimal performance.

He already said. TO be able to pass by having the AC cutoff at WOT. His budget was less than $200.

1991_crxsi

iTrader: (1)

Oh, right... except he started talking about horsepower gains and a "final tune" later.
On another note, your posts here were spot-on... but you already knew that.

grumblemarc

iTrader: (4)

Thanks. I'm guessing as a by-product he probably wanted some additional power as well.

rovafa2002

OK you got me, I wont be spending that money on it. I just wanted to take advantage while being in the US. I live in Uruguay, there is no-one there but I mean, no one who has the ability to easily tune a Honda. I guess my only option would be to get a S300 but its too much for a Car that is stock. So I guess I will save those U$S200.


Thanks everyone for all your input. Really apreciate it

I can wire a relay that you have to solder behind your dash. It connects to the AC switch and the TPS.

IF TPS>50% THEN AC=/=ON.

Boom! DONE.

I'm a freakin' genius. I'd assume you need something to sense voltage and some basic wiring knowledge. I'm sure there are corners of the internet that can help you with this.

Total <$20.
