chips

[liljoe102006]

which one is better venom or the jet programmers

[yogi_pahl]

if you ever find out let me know been looking on them too

[94preludeguy]

They all suck.

[prelude24]

They all suck.

x2...ive herd from enough people that preludes are just not ment to be chiped because it barley does anything for the price

[donepps]

why do they all suck? and is this the same kind of chip a bunch of people put in their gti's?

[satwilson]

Any chip has to be programmed and tuned to a specific car and its other mods(header, intake, exhaust, etc). There is no power to be had by just installing a chip unless it is programmed and tuned. I assume you want to chip a Honda Prelude because you are on this forum. Your best option is to use an OBD1 ECU as they are the only ones Honda has that are programmable. If you have an OBD2 unit you can get an adaptor harness. The best ECU to use for a Prelude is the P72 from an Integra Gsr as it is the only ECU that can control the Iab intake on Preludes. Once you have a p72 then get a chip, my choice would be a Hondata S100,S200, or S300. Make sure you have a OBD1 P72 as they also came OBD2 in the newer models and aren't programmable. Then take the car to a Hondata tuner and they will put in an H22 program and then can start to tune it to your car. There are other more expensive aftermarket ECUS available, but I have an S100 in a 98 Prelude with IHE and it runs much better than the stock ECU. Anyone who tells you they can increase power by just installing a chip without tuning it doesn't understand how complex this can be. If you have any mods to your engine this is the best way to go.

[twokexlv6coupe]

EXTREMELYYYY good post wilson!!!!
you sir, get a rep for that :cool:

[rheakpl]

agreed for the most part as satwilson..

i think of it essentially as 1. chipping vs 2. a piggy back system vs 3. an actual standalone system.

1. to me, chipping is an easier/cheaper quick "tune" you can call it...
it depends on wat you want out of your car...if you have say i/h/e and you that may be all you want, then a quick chipping to optimize you fuel management would always be a plus.

2. a piggy back system is cheaper compared to like a real stand alone system but its like an option...personally i dont think i ever want a piggy back like a vafc etc because it essentially is tricking the ecu into manipulating fuel management...and not really changing the fuel management physically..
you can manipulate the vtec engagement as well..but its not recommended if you think being in vtec all the time is the best for your motor.......in fact you can loose some power if you engage too early.

3. ah..the stand alone...is more in depth...this is really tuning your car..
you would have to get like a hondata, neptune or crome onpaired with an ecu. this is costly and you will need to bring your car to someone to get tuned/hook it up to a laptop to do it yourself... plus dyno time if you go elsewhere..

ecu wise...there are a couple of choices...
like satwilson mentioned the p72 is great since it takes care of your secondaries...but that integra gsr ecu is expensive...vs say an obd 1 p28 which is muchhh cheaper...i perfer it over the p72 because the timing with openin the iabs are still a tad off in that ecu...and i plan on usin a different intake manifold that has no secondaries...the p28 also has no egr...so you can just block it off too =]

sorry for the babble got carried away..hope something helps..
do correct me if im wrong, thanks.

[Si Speed]

Red for Wilson and Jen.
Keep the info coming. This is going into the resource guide.

[jamesls]

where can i buy a obd 1 p28 and is this something i can install what do you have to do??? btw i have an 01 prelude base 5sp with the h22a4

[donepps]

do these chips effect the reliability of the car? if its a daily driver for example...

You'll need an OBD2-to-OBD1 conversion harness first. I believe 99+ is OBD2-B but double check that before you buy the harness.
You can get the ECU out of the 92-95 Civic EX's at a junkyard or just search the internet. Get a virgin one though that way you can make your own settings from scratch instead of having to override someone else's.
You can install it yourself. It's located under a metal cover under the carpet on the passenger side of the car. I reccomend just taking it and letting the tuner do it so you can install it and dyno tune it without having to drive it around.

Not if they're tuned correctly. :smile:
If they're not tuned, then it can bring harm, who knows what kind. :redface:

[CHILLZ_VTEC]

so what if you have and a/t (vtec of course)????? hondata makes nothing for it...aem is too much and is mainly for turbo or supercharged cars...ive heard staying with the oem ecu is better if you have just an i/h/e/p, but if theirs something out their known to gain whp for an a/t base, what is it???

[mckillio]

Will you lose ATTS if you switch to a P28 or P72?

[BadMofo]

Absolutely will... You will loose ATTS with anything you do tuning wise except for a VAFC, SAFC Neo, or Greddy E-manage. If you wanna keep ATTS, you gotta stay with piggybacks.

most chips dont work or they work by tricking your engine! do some research and spend your money wisely

Just want to update as their is a better option than the expensive p72...

eCtune allows iab control, knock sensor, egr... the whole deal... (on OBD1 p05/06, pr4, p28/72) it is a relatively new program, but my shop, Blueridge Motorsports dyno tuned the head mechanics h22 civic hatch w/ bolt ons (like my setup) and got about 45whp with ONLY the ECU change and tune... he had all the bolt-ons prior to the tune and put down about 140whp... after the tune he hit 185... somehow while I was at the shop the other day he dynoed at almost 205whp... that is totally banging on a bolt-on h22 (no aftermarket intake manifold or injectors)

go get eCtuned for about 4-500 hundred bucks.. totally worth it.

http://www.ectune.com/

my tune is pending, but I will post some numbers when I get it in the next couple weeks.

The statement about chipping not helping the lude is bogus... you just have to get a REAL TUNE, not some ebay m*gen chip or a chip from some company that never tuned a Lude... the tune really NEEDS to be specific to your ride... you might be able to use a buddy's map if you have a similar setup, but getting your own tune is really the best option for power, safety, and the life of your engine.. it you want to toast you h22 get an ebay chip.. go ahead, get one without a rev limiter... have fun with that.

Anyone who says that chipping doesn't help a lude is a retard... however, in the context that we are using, "chipping" is indeed worthless.

If you look at the original post, he's talking about the "venom" and "jet" chips that you send away for. The ones where you simply tell the person/people what kind of engine you have and what kind of mods you have, and then they give you a "best guess" chip through the mail when they have never even seen your car. This practice is not only pointless, but dangerous as well. So, if this is what a person defines as "chipping"... then yes, "chipping" is indeed worthless as hell...

Now TUNING a chipped OBD-1, on the other hand, makes real numbers, and is not only better for your cars performance, but also better for a modified cars health/reliability.

[nevrdun]

Im pretty sure I speak for everyone when I say no one here would concider tuning a different ecu the same as putting a "chip" in a car.

So, knowing fully well that these chips are a joke and putting in a new ecu and having it tuned is out of the quesiton, what kind of tuning and gains can you expect to get out of a VAFC in an engine with mild mods? (I/H/E and maybe cams) Will it simply make the bolt ons you did work to their potential? I understand they essentially trick your ecu and can only make small adjustments but is it enough to make other parts worth while? Is it harmful to the vehicle to do this?

[mr_y82]

It can be harmful to the car because the "chips" maps don't run the car as the car should be run (unless you somehow get really lucky, but how would you know)... you might get detonation, or some other problem that will shorten the life of your engine, or you might blow it all together.

Bad Mofo, I understand what you are saying and I think you quoted me because you mostly agreed? Because chipping is worthless or worse, I thought I would explain the only real reasonable and safe alternative.

I did very much so agree with you, I was simply givin' you props and expanding on your point by making sure that everyone knew the difference between simply "chipping" and "chipping + tuning". Good posts . :thumb:

nevrdun, VAFC is an alright solution if you aren't going to be doing extensive modification, it should do just fine for I/H/E and adjustable cam gears. The only thing to keep in mind is that if you have OBD2, your car will eventually "detune" itself overtime... it's the nature of the beast =/

[nevrdun]

^ So can you over come this by disconnecting power from the ECU thus "resting it"? Say you hooked up the power to the ECU to ignition power, would this work? The ECU has to have a nonvolitile memory for its base settings right?

[GreedyTurbo529]

How do you know if your car has a chip or not? I was told that the lude I bought not too long ago had a chip but I have no idea what to look for to find it, I want to pull that baby out

[AmericanManiaK]

which one is better venom or the jet programmers

try out the SURGE PERFORMANCE CHIP it adds 35 whp---20+ ft. lbs of torque and 1-4 mpg.......It also adds faster 0-60 times 1/4 mile and 1/8th mile times and faster acceleration at all RPM and its only 85 BUCKS!!!!! and it works wonders all u gotta do is plug and play :)

[mr_y82]

it better accelerate faster if it adds 35whp and 20+ ft/lb... could you give us a link to look at this thing? Numbers are pretty specific, are they for a stock setup or what? It's always a little suspicious to see these types of exact numbers... like the little resistors people sell for you to put in your intake and "add 20hp"... where do you find info in this thing?

I hope you're joking...... If you believe that, I got a "tornado" I can sell you.




Nevrdun, resetting the ecu does not work around the OBD2's learning abilities... At one time it was thought that resetting the ecu would keep it from learning (thus eventually negating any gains) but since then it has been determined that it doesn't work =(

[mr_y82]

ew, ew, a tornado, I'll give ya 50 bucks for it! between that and my radio shack resistor you boosted boys better watch out.

on a side note, anyone ever built their own "supercharger"
http://www.hondapreludemodifications.com/super_charger.htm

seemed like an appropriate place since we are talking about pointless "upgrades" and this is potentially another one... at least this isn't just an ornamental fan for your intake.

[nevrdun]

Not a resistor what good would that do? Come on noob you need a polarized .47 microfarad cap. What are they teaching in school?!

Thanks for the info on the ECU.

[mr_y82]

Not a lot :)

[BadMofo]

Hey... Figured I'd post this up in regards to the theory of resetting the obd-2.

NTPOG page regarding the obd-2 "workaround"... (http://www.ntpog.org/mods/fifth-afc/afc.shtml) It's in the fifth paragraph

[96jdmh22a]

any pics of the inside of a stock p13. i got a obd2 in right now for when i get my emissions test because i got a 93 motor in a 96 lude.but i opened it up and inside there looks like what seems to be a chip it has verry blurry writing/sticker on it cant even tell what it says.... if it is lieka egay chip how can i take it out??? im not to savvy with electronics, will it just pull out or does it replace something?

[mr_y82]

I have a p13 sitting on my desk... beside a p14... but no camera. Do you have an obd1 ECU?

[1998luder]

i have a same supercharger thing i bought it off ebay and it says it'll increase 10-25% hp gains depending on your cars setup, so you guys are saying when its turned on it won't make even a little difference ???

[mr_y82]

pretty much :) ... is it a "fan" or a "chip"?

[1998luder]

its a fan which works as a turbine ...i mean like if has to be powered tho

[mr_y82]

is it an electric fan, or does it just sit in the intake and "smooth out the airflow"?
these types of things do nothing at best, and probably inhibit airflow. :(
http://www.turbonator.com/WhatIsIt.html

[1998luder]

nope its a 2 end motor. It fits in front of the intake one end goes in the intake other end has a filter on it and when it moves with the electricity its throws in air in the intake while pulling in air from the other side of the intake . The link you send me is nothing like that i have a link that's wat i am talking about. DO you think it'll work ??

[mr_y82]

ohh, I've seen those... and heard some people say they don't give a gain... I don't have any evidence either way, but there is a better chance it will do something since it is powered... I know some guys who know more than me say they don't work...

here's some instructions for a homemade supercharger... don't know anyone who has tried it.
http://www.hondapreludemodifications.com/super_charger.htm

[nevrdun]

Those fan things are no good. They only time having forced induction is of benefit is when it creates a higher pressure in the intake manifold then the pressure out side. Now this fan isn't creating any kind of pressure simply blowing air that is probably already at a higher velocity when your revved up. Cant see this doing anything positive.

If they're not tuned, then it can bring harm, who knows what kind. :redface:

so then you just basically change out the ecu? (with the right tune and harness of course) thats all there is too it or is there more? seems too easy

[96SLUDE]

I like the crispyness of Wise, but utz comes through at number two just because they are sooooo greasy, Lays is alright there kinda like the McD's of chips though.
