Hey im wondering if performance chips do what they say or is it just a scam... I've seen sum that say they add 60hp and 7mpg. Also the you can install them urself easily... it seems to good to b true. Anyone have any good or bad experience? Also what's my risk of doing it myself? Im moderately mechanically inclined.

Chips off ebay arent the best bet for motor and setup and here is some info about chipping a ecu hope this helps.
Originally posted by d112crzy View PostQ. Why should I/do I need to chip my ecu?
A. Stock ECU's can only do so much after mods have been added. When you chip an ecu, there is software you can use to customize fuel and ignition maps to your engines liking and make the most power out of it.
-------------------------------------------------------------------------
Q. What do I need to chip my ECU?
A.
1. A chippable ECU(I'll give a list of chippable ecu's later)
2. Ability to burn (e)eproms. You need an EPROM programmer or a friend with one. If you'd like your very own I recommend the Moates Burn1/Burn2 ( http://moates.net/ ) or a willem chip burner(you can get those on ebay) and some (e)eproms.
3. Quality soldering tools. I personally use RadioShacks 15w soldering iron and their 45w desoldering iron.
4. A chipping kit. You can purchase them from www.moates.net.
-------------------------------------------------------------------------
Q. How do I chip an ECU?
A. It is a lot simpler than it sounds or looks. All you need are a good soldering iron(even those cheap craftsman solder guns work), solder wick or desoldering station.
The parts you need are as listed and can be purchase from www.digikey.com:
Qty 2: 0.1uF Capacitors
Qty 1: 1k ohm Resistor
Qty 1: 28pin DIP socket
Qty 1: 74HC373 (make sure you get a 20pin DIP version, not SIP)
Here's an illustration of where all those parts go
Here's a great video on how to chip an ECU

-------------------------------------------------------------------------
Q. Ok, sounds cool. So...which ECU's are chippable?
A. First off, Accord/Prelude ECU's are chippable, but you can only edit timing. You can also remove a few things you dont want. So, it's pointless to chip them b/c teg/civic ecu's are fully programmable.
But, the following ECU's will work for ANY OBD1 application with the proper tuning.
1. P05 - non-VTEC, 1-wire O2 sensor, no IAB. This ECU is found on 1992-1995 Honda Civic CX models.
2. P06 - non-VTEC, 4-wire O2 sensor, no IAB. This ECU is found on 1992-1995 Honda Civic DX/LX models.
3. P28 - VTEC, 4-wire O2 sensor, no IAB. This ECU is found on 1992-1995 Honda Civic Si/EX models.
4. P30 - VTEC, 4-wire O2 sensor, no IAB, knock sensor equipped. This ECU is found on B16A Del sol's (pretty rare ECU).
5. P72 - VTEC, 4 wire O2 sensor, IAB, knock sensor equipped. This ECU is found on B18C Integra GSR models.
6. P75 - non-VTEC, 4-wire O2 sensor, no IAB. This ECU is found on B18B Integra RS/LS/GS models.
You can chip any ECU to be the equivalent of any other ECU. For example:
I have a p06 and one of my customers needs a p28 or an equivalent. I can convert it to vtec. I can also add IAB's and a knock sensor.
-------------------------------------------------------------------------
Q. YAY! I can chip an ECU now, but what ROM tuning software can I use?
A. I'll give the two most popular freeware that people use: Crome and Uberdata.
Crome Pros:
- FREE!!
- VERY user friendly (I think thats why so many people 'like' it)
- First editor to feature scripting (allowing the end-user to enhance the editors functionality)
- Generally stable releases only... usually no 'surprises'
Crome Cons:
- Seems to be irregularly updated these days.
- While it was the first to incorporate scripting, its limited and can't assemble ROM's at this time
- Support is pretty much limited to the pgmfi.org community/forum
Other software:
-Crome Pro(MUCH more features than regular Crome. costs $150)
-eCtune - $175 for 1 license +ostrich
-Hondata - S300 is the best unit out and most tuners won't touch any other versions. $599+
-AEM EMS - Not the best for Honda, but definitely still better than most. $1000+
-Haltech - On par, if not better than AEM. $1200+
-Neptune - On par with Crome/Hondata/eCtune.
-Mega Squirt - for the COMPLETE DIY'er. Costs vary on how much you do yourself -
Thanks Much! Perfect Answer!!!!!!!!!!!Comment

No generic chip is going to help your engine. The ECU should only be tuned properly for your particular engine... and you can't chip any Accord or Prelude ECU. ECUs from Civics and Integras are used.

If there was a way to get 60hp and 7mpg you can bet honda would have already done it from the factory.Comment

p13 from prelude is chippable and commonly used
it also has iab factory so good for H swaps were iab is retainedBudget Street is offline working in the shop

Wouldn't it be fantastic if we could drop a total of $500 on products from ebay, or the back of a magazine... and end up with:
300hp cars that get 30mpg
12" schlongs
The interest of every beautiful woman in the world
A work-at-home job that makes 6 figures
0 body fat and ripped abs
and an unbeatable immune system

It is chippable, but it the options are very limited in terms of what can be tuned. Far more control over engine management can be had with Civic and Integra ECUs, as they have been fully "cracked".Originally posted by budget street View Postsorry deev

Essentially, the PT6 and PT3 could be chipped as well... just with very limited options.

true the p13 is limited because fuel tables need to be edited manually
which make p72 gsr ecu a better choice for iab ecuBudget Street is offline working in the shop

Absolutely.
Since any chipped Civic or Integra ECU can be considered a blank slate, there's really never any need for someone to bother with an Accord or Prelude ECU. The only reason to even consider messing with the Accord or Prelude units is to attempt to make them as usable as the Civic and Integra units.

Would you be able to use the ecu before a tune? or could you just hook into a p72 and just be ok? I just don't understand the difference between each ecu like timing and all the other stuff that might be different between a GSR and accord ecuOriginally posted by deevergote View PostComment

well a civic or teg is two complete different motors than a F. So which means more fuel less fuel different timing things like that. So you motor needs a special mix of all this to work right. So not enough would hurt your engine thats why cant mix and match ecu's from a civic or teg with out it being chipped for your setup.Originally posted by Jack93prj View PostComment

Using an ECU from a 1.5-1.8L engine to run your 2.2-2.3L engine would be like feeding a grown man a jar of baby food and expecting it to be enough.
In other words... NO. You cannot run a bone stock Civic or Integra ECU. They are ONLY used because they are capable of being fully modified, and essentially turned into "stand alone" fuel management systems.

id say they dont work. i bougth a darkside stage 2 ecu performance chip and it didnt do much for me but trow a cel. i bougth it for like 50 bucks off ebay and what it did was replace the IAT sensor with this box with 2 wires coming out of it. like i said, i didnt notice a difference and i removed it after 6 months. it didnt do any noticeable harm either, that i know of at least. theres sum cheap ones on ebay that wouldn't hurt to buy if your curious, this way you loose less money.Comment
