Q. 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
