Here's what I'm working with. 90 CRX DX. DPFI to MPFI. OBD0 to OBD1. D15b8 bottom w/ z6 head. About 5k on new rings/hone, bearings. etc. All stock except for ARP head studs. P28 auto to man.

I took my valvecover off tonight to check things out (dissapearing coolant). Checked to see if head was coming loose. I noticed something fell when I got the cover off. The bolt that is on the rocker assembly above cyl. 4 kind of by itself, was off and next to a valve. I'm thinking the hole is maybe a service hole for cleaning, but the bolt is in there to keep oil pressure. I put the bolt back but was just wondering what exactly it is for. Also code 22 popped up whilst flying down the interstate. While light was on I think vtec quit working. Would that bolt coming out let oil pressure drop in the head thus not letting vtec operate?

By the way this site was extremely informative when I built my car starting in April to just a couple of months ago. At 1st I was unsure on how to do things but with the help of all the writeups/ tech I made my own OBD0 to OBD1 jumper, convert to multiport, time mini-me, vire vtec and 4 wire o2. Thanks for the help H-T!!

Forgot the pic

 

Bump, anyone?

 

Check this link https://www.hondapartsdeals.co...+1001 and find the bolt. Good luck

 

Can you please explain or show a pic of your OBD jumper please, I am working on a break out box (BOB) project and have to build all my own ECU interfaces out of actual ECU female connectors unsoldered from the PCB and the original engine harness male connectors with pigtails, then wire everything up. To buy one is about $100 for these harnesses and I still need to cut and build from those. These harnesses you buy are adaptor harnesses, I have to stay OEM straight, wire for wire, no crossover or jumper or repin locations.

Yeah, because you have a real SiR right?

 

Yes wisco i am driving on passenger side. Duh

No you're not. Shut the fukc up and get out. please. PLEASE DEAR GOD LEAVE.

 

look

gosh man you do not like my ride okay that's cool.

 

good for you, you can steal other peoples pics and put them on your photobucket. way to go. i won't believe it until i see at least ten shots of that SAME EXACT CAR.

 

haha the pavement looks the same to me!!! you got owned by JDM BITCH!! hahahah

 

i dont kno either. i mean. he gots all the gooodie in the second pic. first picture, he dont even have the all ambers corner lights?(maybe changed it iono) second, it says SI. iono. it could be his. but if its his, OWND

 

Ok...guy wanted help...did you find it Rockgate?

I found that it's a seal?

 

yea. i got pownned fer sure.

look at any of this guys posts, he asks what a poormans type r is and then are telling people how to build their motor in other threads. there is NO way he has a rhd car. no way no how. end of discussion.

that would technically be the driver's side.

first you post a picture of a USDM si (si badge and usdm tails)

then you post a picture of a RHD siR. are you gonna tell us you changed the badge and tails on your car, but now want to change them back?

 

Ya I seen it's a "seal", but what is it sealing? Just an oil passage? With that bolt being out would that dissable vtec? And about the jumper. I was meaning harness adapter. Got OBD1 harness from car, and OBD0 sockets from ecu. Whats a break out box? Here's pics anyway.

 

You said you were working on one? As in designing and building your own?

careful, you might get JDM STYLZ PWNEEDDDDDD. obviously anyone that rocks usdm is total noobage and has nothing valid to say about this moron. I swear JDM is becoming a moniker for asswipes and rich boys to act elitest and talk down to kids outside of their scene. expletive-a JDM and people who don't know that 9 times out of 10 the usdm counterparts are just as effective.

what ever happened to the ban thread for this poser?

YES, I have designed and am in the process of building my own, what I call the worlds largest break out box (BOB), it will fit in the passenger seat but will have harnesses long enough to go in the back seat, unless is start getting feedback or EMF type RFI or some **** then I will have to do some additional shielding. It is universal and will eventually hookup to any and every cars ECU and many other electronic computers or even a two wire part or an AC computer. In the case is 100, 5 way rotory switches, planned on 200 but cut it down, a laptop and a portable 4 channel scope. I found a 50 wire, 14 gauge harness in Little Rock so I bought a piece for the prototype.

I have to build harnesses similar as pictured without crossing anything, straight pin for pin, a female half to my harness and a male half to my harness, and my own universal harness between each model of vehicle male and female and the BOB.

The BOB goes between the engine harness and the ECU, I turn on which ever 4 switches I want to watch on the scope and look at the heart beat of the engine input to the ECU or the output of the ECU to the motor actuator. Turn them off and turn on 4 more until I look at every wire going to the ECU and figure out what is wrong. The laptop has my Mitchell On Demand repair manuals, a huge database of repair info, hundreds of shortcuts to links if I need to get on line through the cell phone. I have also created a step by step tutorial of which 4 switches to turn on first to monitor a cold engine, what to check before the key is even turned on, what to check when the key is on and engine is off, what to check while cranking for a start or a no start scenario, and while the engine is running from open loop through closed loop and then on a test drive in case its a drivablilty issue or a dies at stops. My tutorial tells me what voltage to set up each channel of the scope and what time span to watch the pattern that I am monitoring so I have minimal switching back and forth. No memory issues here. I will have a library of good and bad patterns when available. Pics of where to plug in a scope test pin if needed to go out to a component and specs for the component, notes when needed because sometimes the repair manual just does not cut the mustard. Anyways its over due and over budget but I get almost all the ECUs and harnesses for free. Enough of that crap. A Snap On (Sun) Dynamic Data Collector (DDC) with harnesses is about 150,000 US I think, at least its a butt load of cash. I am emulating that at a fraction of the cost. It uses USDM software and its no good over here, not that I could afford it anyways, I am no John Anello.

I'd love to see it. A vote on Deportation!

 

Since this turned into a FS/WTB thread even though OP has nothing to do with it. All involved will be loosing a % if you want to contact someone about buying something use the PM's
