Re: From the Ground Up. Build Thread.
I did not know there was a filter option/DIY. Any links? Would like to check it out, I did think about it while I was in there.
Nah. I took all that out. I like the noise in this car.
I have another daily driver that is quiet and has AC, so I can keep my sanity.

Re: From the Ground Up. Build Thread.
@deschlong I think can help you out with the retrofit. He can correct me, but I think all you need is the condenser portion of the box from a 97-2001 CRV.

Re: From the Ground Up. Build Thread.
I can't figure out what year the car is - more importantly, whether it's an R12 or R134a system. Both can have a cabin filter added but the process is a little different for each. Check my signature for a link to all my DIYs including the Cabin Filter Retrofit one.

I updated my comment to include your information on that at apparently the same time you commented. Lol

Re: From the Ground Up. Build Thread.
So, after letting the car sit for a couple years, I decided to try and get a smog. Had to do maintenance, oil and filter change, oil pan gasket, check and change vacuum lines, drain and fill coolant, set timing. Went to DMV and gave them a paycheck (payed three registrations at the same time). Went to insurance and gave them another.
I go in for smog, not expecting to pass, and I don't. Tech wants a new cat, and says there's a leak before the O2 sensor.
Went home, ordered a cheap header with a $250 CARB sticker. Most expensive sticker I've ever bought. Get the header, install header, hate on header, then hate on the header some more. After more header hating, I took the car for a new cat. Dropped it off in the morning, picked it up in the afternoon and went straight to smog. Driving over, CEL pops on, plan ruined and went home. Read the code, VTEC, nothing to do with smog. Solenoid wire broke off, easy fix.
This is round three now, drive to smog, I'm told I have to go somewhere else. Car is a gross polluter cause it failed ONE time. Stupid. The tech got excited and wanted to see if it would pass, threw it on the rollers and he said it was all good now. Took it to the over priced smog god, not really caring cause it already passed that day. No surprise, I got my certificate.
Now I'm good for two years, time for a little fun. Couple of parts may have been ordered.

Re: From the Ground Up. Build Thread.
Time for another round of "upgrades". I've been collecting parts for a while now, researching and making a complete plan.
First step was to complete some work on the race head. The head really deserved a good valve job, and the guides replaced. Before I took it in I went ahead and gave the intake ports a burr finish to help keep fuel atomized and not collect on the smooth walls.
Fresh from the shop. Supertech flat faced valves, deshrouded and polished combustion chambers, 40cc high-compression.
Complete Supertech valvetrain. 85# springs, retainers, keepers, valves, valve guides, valve seals, and beehive LMAs.
I had some difficulties CCing the head before, spent time this round and got repeatable measurements. All measured at 40cc. Using the Zeal Autowerks online compression calculator, I'm looking at 12.2:1 if I bolt this to the built block, and 10.4:1 on my stock block.
Thinking about tuning a high compression engine as my first, might not be a great idea. Did I mention I'm going to learn and tune this myself? I figure I'll start with a lower compression build first, the stock engine will be perfect for me to learn. Then I can bolt on this race head and see how the airflow has changed through tuning. I think I should learn how to set fuel tables too, so I'll be setting up the ECU for E85 and flex fuel. Should be fun. More to come.

Re: From the Ground Up. Build Thread.
Hit the + button. ECU tuning.
After a little research, I decided to run a S300. Being able to do most of what a stand alone can, at third the price. I wanted something that was simple, plugged into the factory wiring and was compatible with an ethanol sensor.
I had two ECU's that I could have installed this in, a virgin p72, and a modded p05. After more research I really wanted to install the Hondata into a virgin ECU, less to worry about, but I didn't want to use my p72 (I need it for smog). I found that I could use most any OBD1 ECU, that I could add VTEC and even do an auto-manual conversion if I needed. Pretty cool! I went to the pick and pull and took a look around. Every Civic and Integra ECU had been taken out, except one, a p75 from a manual Integra. Car was clean inside, and the engine was a runner so I hope the ECU is okay.
Found info about changing the capacitors as precautionary maintenance before they leak. Seemed like a good idea so I ordered the kit.
I hadn't done any soldering in a while, so I just jumped in head first. After a couple joints, it all came back to me. Started with the capacitors, then installed the S300. I have a 1980 VTEC kit on order, will be here next week.
And as I'm going to be self tuning, I needed to get a wideband kit. Thinking about what else I could possibly want while looking at kits, the Innovate ECF-1 checked off quite a few boxes.
-lambda based unit instead of stoich, no need to worry about e85 or gasoline wideband gauge
-Flex Fuel sensor included in this kit is more accurate than other popular sensors
-includes a fuel pressure sensor
-gauge will show fuel temps
-gauge displays all 4 readings simultaneously, lambda, e85%, fuel pressure and fuel temp
-logging with s300
This is going to be a learning experience.

Enjoy - data collection and analysis with the S300 is fun.

Re: From the Ground Up. Build Thread.
Ya. You're right. Stoich is just a conversion from lambda.
It was more a vanity-decision for me, or me being pessimistic and indecisive. I'm not really sure. I didn't want to pick between an "e85" or a "gasoline" faceplate for the gauge.

Been looking into hooking this up to the S300 for ethanol reading, and I've seen that I don't need the resistor. Need to do more searching/research about this.

Re: From the Ground Up. Build Thread.
This can display AFR as well. I can see the benefits of using an AFR scale when tuning, having a finer resolution (scale table). We'll see what works best for me.

I too used lambda at first, but ended up going back to AFR...nearly everyone talks in AFR, and anytime you're troubleshooting it will prevent you from having to do math to figure out what someone means.

Re: From the Ground Up. Build Thread.
I haven't looked that deep yet. If you have a cheat sheet, I'd love to look at it.
What are your S300 inputs filled with now? I'd like something to have a baseline off of.

Re: From the Ground Up. Build Thread.
Here is how I have my flex fuel wired. I've got the wideband signal going into D10, boost control coming from A11. AN0 for flex fuel is the only analog input I have running straight to the S300. If you decide to use the analog signal into the ECU for flex fuel, there are only a handful of ECU inputs you can use and one of them is D10, which is the preferred input for wide band. In the future I may try to log oil pressure with another analog input.

Just joined the party and went through the entire thread. Hate to sound like an echo chamber but you're doing great job. Honda ECUs are something else, it's like they were made to be tampered with.

Re: From the Ground Up. Build Thread.
Well, you guys jinxed me.
Hondata is installed. Map loaded, knock disabled, fired right up. Let idle and looked through everything.
After about 5 minutes I noticed the o2 voltage stuck at 3.77 and AF was 1.2. Water temps got to 180, and the o2 was still reading 3.77v.
Any clues or ideas what I'm missing?

Re: From the Ground Up. Build Thread.
Pulled the o2 and it was black with soot.
Installed a Denso I had bought a while back.
Pulled the car into the garage just fine, so next time I'm just going to take the car for a drive and get the sensor hot.
It's nice doing this on a stock setup so I can just plug the stock ECU in if I need too.

Re: From the Ground Up. Build Thread.
Took the car for a drive. ECU must be getting the correct readings from the o2 sensor. Car drives fine and no CEL. Guess I'll just go wire-in the wideband and go from there.

Re: From the Ground Up. Build Thread.
Installed different o2, get different code. lol. Think I was stocking a bad one on the shelf. Gotta get this wideband in.
Looking into making my own harness. Have to decide if I want coded wire or just black wire with labels, and how to crimp shielded cable, and what tools to buy, and how to make it last (MIL spec boots maybe?). Probably going with black so I don't have to store a bunch of left over (and expensive) wire.
Besides that, I've been working on an ECU cover, made from the screen protector off an old rear projection tv.
Like the brushed aluminum, I think I'm going to make this screen a thing. Would be cool to make a gauge cluster with the stuff, and show off the wiring behind it. Maybe a switch panel with the breakers behind it with a hinge system for access. Dunno, just thinking.
