editors note: Originally posted by Adam P and edited for cleanliness.. How to Chip a Honda OBD1 ECU Saved here in the forums for preservation USDM OBD1 ECU Chipping So, you want to chip your obd1 usdm ecu. You didn't listen to me tell you to get a Hondata, or if you did listen and you are reading this... good job. On a scale of 1-10, the difficulty of chipping an ECU is a 3. Just follow these simple instructions and you should be revving past your stock rev limiter using your stock valve...
 
i take no credit for this... but i built mine own according to this article. Browser Warning bought my materials at rad shack for $20 open it up. the microphone was cut off of the circuit board. take care to not forget the polarity. i wired up 6ft of wire and soldered it to the mic, then stuffed it into the alligator clip and secured it. repeat on the other side. i used green for negative and red for positive. put it back together and test it out. works best with a friend...
I was watching a video and the editor made a comment while racing (a V-8 Camero at a rolling start) which was "never let a V-8 get a torque jump on you, So brake boost the hell out of your car"? What exactly is Brake Boosting and how does it work? wondering if you can post it in General Tech Articles Video: Turbo EK hatch challanging dometics - Honda Videos Appreciate it D
 
Please move to the General Tech article's forum or where you see it Ok before I begin, I know that their is already plenty writeups on this but I've found most of them to be incomplete and only cover the actual installation o the wheel. In this write up, I intend to give you as complete guidelines as possible to remove the stock steering wheel, install the new hub, quick release, and steering wheel, wire the horn, jump your srs system so that your other airbags still work, and how to...

Heres a step-by-step walk-through of how to change a Head Gasket on your Honda's D-series motor. And btw, sorry for some of the blurry pics... I'm not a photographer :p 1. Start unplugging wires and hoses. Everything attached to the head from the car's body or the block MUST be disconnected. 2. Unbolt your header. I had to pull out my A/C fan to get it to clear the studs on the block. 3. IMPORTANT STEP! Set your motor to TDC (Top Dead Center), where the #1 cyl. is on the Intake...
 
I put this guide together because I'm tired of seeing the SAME threads over and over of simple questions that can be answered in one simple post like this one. This is just a general guide. Feel free to comment with something if you feel it should be added to this guide. Thank-you. Also, please be aware that this is on an intermediate level, and in my opinion anyone reading this guide can perform all of the steps outlined. I left out things like how to hone cylinders, install bearings...
Okay, guys. I just got done changing the fuel filter on my 1994 Honda Accord, and it was a real bitch. So, I thought that I would take a few minutes to write up a thread giving recommendations on how to make the job easier based on what I went through. I promise you, if you follow my advice, this job will be a lot easier. This is not a job that you want to embark on without sufficient knowledge and the right tools for the job. So, take a few minutes and read what I'm about to write. I...
 
Soldering is the best way to connect wires most of the time; but some circumstances call for crimping. Crimping is pretty straightforward, but it is so often done wrong that I think it warrants a tutorial. Even if you've been crimping for a long time, you can end up with 1 in 10 bad crimps. I find that unacceptable, so I developed a strategy for getting nearly all crimps perfect. The most critical effect on the outcome is from your choice of tools and supplies. I've found that Channel Lock...
 
In these photos I'm changing the plug connector and replacing a missing bulb socket on a tailight I got at the junkyard. That's not the point though. The point here is to show you guys how to solder. I see a lot of crap wiring out there. It's scary, it's just bad and there's no reason for it. Soldering doesn't require any expensive equipment or any great skill. It takes less than $50 for tools and supplies and maybe a couple hours practice. Tools Required: *100 Watt soldering "gun" from...
 
I put this guide together because I'm tired of seeing the SAME threads over and over of simple questions that can be answered in one simple post like this one. This thread is designed to be an end-all, tell-all type thread. Please keep in mind though, that this is still just a general guide. Lsvtec/b20vtec engines are not honda manufactured engines. With that said, there are hundreds of combinations you can build. Also, please be aware that this guide is assembled on an intermediate level...

This is something that I see come up, and sometimes people get confused by the written instructions, so here's one with pics. This can also be used for wiring just about anything you need, like a knock sensor, IABs, o2 sensor, whatever. I HIGHLY suggest have a manual with a wiring diagram and the pinouts, for your ECU, you don't want to screw up now that your motors in right? Ok, assuming you have a vtec motor in a non vtec car and you need to wire in vtec y0! here it is... Our...
How to change your axle(s): 88-00 Civic, 90-01 Integra The axle swap only takes about half an hour (for me). If it's your first time, budget out about 1-2 hours. You'll need a 14mm socket, 17mm socket, 32mm socket and breaker bar (for the spindle nut), ratchet and torque wrench, hammer/mallet, pipe wrench (my preference). Get some cotter pins to replace the old crusty ones from your castle nuts too (two total if you take EVERYTHING apart). What I basically do is: Remove center cap from...
There are two basic types of injectors that work on Honda and acura cars. How they operate are totally different. Let's take a look. Peak and Hold: Peak/hold injectors are low impedence, usually in the 1-4 ohm range. When the ecu calls for fuel to be injected, it sends out voltage via the wire clips until a certain current level is reached (the peak part) (varies by injector size, company). For the duration of 1 pulse width, that current is slightly reduced and held (the hold part)...
 
How many valve reliefs are in D15B6 pistons? Q: Why does anyone care? A: If you're going to swap the head on an HF engine to a 16 valve D series head, you might need a set of pistons with 4 valve reliefs each. So here we go- courtesy of ryan89crx, who pulled the head on his 89 CRX HF just to see how many valve reliefs he had in his pistons. There are only 2 reliefs per piston. Thanks Ryan!
 
Lost motion assemblies are basically valve springs for the VTEC followers in your valvetrain. The normal intake/exhaust followers have valves and valve springs to press against so they're not flopping around all the time, but the VTEC followers don't. The LMAs help to control their movement. I took some pictures a year ago when I was swapping out my LMAs. I went ahead and marked one of them up real quick so you can see exactly where the LMAs sit and what they look like: The picture...
