k guys i wanna use my s300 as a diagnoses tool on a pos 95 automatic accord. I understand the egr isnt supported nor the automatic trans (will it even run or drive with the manual s300? will the coverter clutch lock up?) and that the heated o2 wires need to b switched. So my plan was to unhook the egr and disable the o2 heater. All I want to do is pull up the display so I can examine all the sensors. I dont really need to drive it, just crank it up. I also noticed a resistor box for the injectors, is that a problem? i dont wanna burn my ecu up. So let me know what u think, thanks brett.

 

bump

 

Rather than try to retrofit a device not meant to even run the vehicle, why not post what's actually wrong and what you're experiencing? More than likely others have had similar issues and can give you a pretty good idea of what's going on.

It personally seems like a lot of trouble to go to to troubleshoot your "pos" Accord.

I also don't see the need for a same-day, two-hour-later bump when you were still on front page.

 

retrofit? its direct plug in! and its not my accord and im getting paid for it. On the bump, i must not of seen it. Rather than being a *** with no informative input, y dont u not post on my thread. That way when i look in my recent topics and c someones posted I wont have to come all the way here just to talk some **** to a dumbass with nothing better to do than try to moderate the forums.

As for the answer, i was told that there is no issue on cranking and starting but it wont drive due to the auto and manual ecu

 

I wouldn't consider that being an *** at all?

You give absolutely no information on the car's problem, no one can give any informative input. I have played with the ECU harness before with my H22 swap, so I'm knowledgeable in that area.

And yes, retrofit is the correct term...from their (Hondata) application list:

http://www.hondata.com/wizard/wiz_accord_90_lxex.html

You are having to modify the harness to get it to work, not to mention the manual only (which you were aware of). That's what I would call retrofitting.

Well as an amazing point to start, I would probably get the correct ECU for the vehicle. If the car is actually able to start up, crank, and idle fine and won't drive I would be looking moreso at the transmission or TCU - since the car has a separate one.

Also, you don't even seem to have any clue what the issue is either, what else have you done to trouble shoot it? CELs? Blinking D4 light?

 

I really don't think he was trying to be an ***, and yes an s300 is "retrofitted" unless things have changed within the last 2-3 years.

 

Thats saying the stock accord ecu cant b modified to a s300. I already own the s300and it wasnt throwing a cel so im not sure, i will b checking it out tomorrow. A lot of things are made much easier when u can view everything on one screen. I told u all i needed to do was view sensors and just run the motor, and ur assuming i dont know what im doing and I consider that *** like.

 

What in the hell is up with all the retard civic guys coming in here?

Nothing Muffin said was mean or anything like that, he simply stated a logical statement. So how about you stop being a grade a douchebag or GTFO of the Accord forum.

 

Yeah i kinda figured u guys wouldnt know much and b ****** about it

 

Point of stupidity proven. Muffin gave advice and asked a simply question with ZERO negative comments and you replied being a complete ***. What do you expect? I didn't know it was that hard to understand....but I guess for people like you it is.

BTW, he is the guy who helps the most people out and is one of the most knowledgeable people in this section, especially with 5th gens. Yet you act like he is an idiot. Pfffff.....wow.

 

cmon dude, muffinman has like 10k posts and you come on and basically tell him he is a dumb ***. you arent gonna get any help that way.

you are going about the diagnosis backward. the s300 isnt going to give you too much more info than you already have. map and ect, thats about it. not worth the hassle of trying to get the s300 to work.

 

wow guys! i mean really. His first sentance was completely condisending if u cant see that than i understand where ur coming from and prove my point of ur stupidity. Anyways I spelled it out for u guys what i was trying to do and u still act like u dont understand and assumed i didnt know what i was doing. The s300 will give me everything, I can test every sensor by just looking at a screen instead of unhooking and testing every sensor. How is it not much more than what i already have. tps, ps, speed, ign adv, fuel supply, 02, iat, ect, tons of compensations, iacv, fuel pump, ac, and i promise i can keep going. The only reason Im posting anything after muffinmans post is so that people in the future wont have to deal with ignorant turds like you and can just get the info iv already recieved from a tuner on carolina hondas (90% of people on this site are great and know there **** unlike ht, esp the accord forum obvioiusly). But thanks anyways guys, now u know the s300 is direct plug and play and all u need to do is disable the o2 and unplug the egr....the more u know the less of an ******* u r, not get educated bitches!!

 

I honestly was not being condescending at all when I posted that, I'm sorry you took it that way but there are easier ways to troubleshoot a vehicle than going through the trouble of connecting something not meant to be connected.

If you actually did get your S300 to plug in and give you readouts on the 95 Accord's ECU and TCU, why be a douche and not post it? I'm actually curious to see where you even found what the nominal readings are for the sensors you have listed.

Considering you got one response that says "Yes it'll plug up" I don't see that as being much more helpful than asking you to describe what issue you're actually experiencing. I also don't see how one person constitutes as 90% of the user base.

haha This guy is so stupid.

 

ok guys i guess my last sentance was a lil childish but thats how i act when im around childish company. Now all u guys are jumping on me cause ur lil leader thought it wouldnt work and was a dumb idea to "retrofit" the s300 into the accord. Now for the facts, its a direct plug in and will still drive and crank fine. So u guys can get off his ***** and hop on mine if ud like. Heres the point i was tryin to make as far as carolina hondas is concerned (this isnt my first honda question). Anytime i have a question i post the same thread in here and on ch. Almost everytime on ht i get dummys like u guys who really arnt sure what there talking about but will defend there ignorance to the end. On the flip side over at carolina hondas they give me a direct answer to my question without attitudes and what they think would b the best thing to do. This happens almost everytime. SO muffinman if u wanna reference those threads than search my name on ch and ht and post in this thread to confirm my statement.

So i pulled the codes for the accord with the stock ecu and this is what i found, o2, iacv, baro, injector, tdc, and map sensor codes. Now instead of pulling all this sensors and testing with a dvom its much easier to pull the ecu and plug in a s300 which will display all this info. So out of all these codes the only sensor that (besides baro) was an issue was the 02. So i threw a 02 in there and put the stock ecu in, drove it 15 miles (i know its not that far) and checked it again when i got home and now there is no codes but still an iradic idle (which hondata can take care of), so next is bleed the water system and pull the iacv and fitv. Thanks for nothing fellows and hopefully my post will help someone in the future.

 

I'll ignore your first paragraph since it is unnecessary. Is that with the automatic ECU in the manual car still when you received all the CEL? I'm thinking you may have incorrectly counted flashes if the O2 sensor was the only one. In addition to that, an O2 sensor is definitely not going to prevent the car from driving - which is how you described the issue. I'm still skeptical that was the 'fix' however am glad you were able to start the vehicle up with your S300.

Erratic idle can be fixed by doing the FITV/IACV/TB cleaning that is in the Accord FAQ.

 

What? no its a auto accord period. I know all about the fitv/iacv as it affects the civics pretty severly also. I never said the car didnt run, in fact i said there were no cels, but I guess they were just stored even though the battery had been unconnected all night before i picked it up. And now ur saying i cant count, WOW. lets c if i remember correctly it was 1,3,4,8,14, and like 22 i think. Id like to pull em again after its been driven a while but its not my car, although i still have to put in some lights on it so il check it out later this week.

 

Your being paid to work on this vehicle and you don't have the proper scan tool to monitor the sensors or pull DTC's? Does the person who owns the car and paying you know this? Honestly, It would be less of a hassle for you to buy/rent/borrow a scan tool and monitor the sensors that way. Than it would be to try and run the F22B1 VTEC by disabling sensors and using whatever basemap you have stored on your S300 ECU.

1,3,4,8,14, and 22. If those are the codes that were stored in the ECU. I would have to guess that this car is far from running at it's best.

In saying that, you should be able to start the car with your S300 and a proper F22B1 base map. You probably won't be able to get very far. However I have never tried hooking up a manual ECU to an auto car and running it.

 

Misread one of your statements early on - you stated it would start up and crank but not drive. Apparently you were talking about if you used the S300 and not the actual problems of the car.

Based on that statement I originally misread and your fix - I took it as the car would start up and idle but not drive. Then replacing the O2 would have little to nothing in fixing that issue

I took that as "As for the answer to your question" when I asked what problems you were having.

Then when you said you got ALL those CELs but then your S300 only reported a bad O2 sensor and replacing it worked, I took it as you misinterpreted the CELs you had previously gotten and they were one or two higher number CELs indicating a possibly more serious issue.

 

the proper scan tool for obdI meaning to hook up to the data link? Iv never actually seen one of those scan tools, y dont u shoot me a link. the s300 does what a scan tool does plus ten times more. No its not running at its best, it was on 2-3 cylinders when i pulled it in, cleaned out the injectors and put new plugs in and its 100 times better and on all 4 cylinders. Iv already told YOU what i can do with the s300 and yeah i started it as a h22 map i think, whatever the closes base map was. I didnt drive it with the s300 but i did pull it around the parking lot. You guys r just trying to get me to say something stupid now. Ghost what is ur point, theyv all already said what u just said and iv already told u what happened when i put the hondata ecu in. wtf?

I should of took a vid for u muffinman, but yes all suspect sensors were reading fine. Like the map was at -18psi at 1100rpm idle which is good and the o2 was only reading .1volts to like .3volts so yeah that one is bad. I could adjust the iacv with the s300 (it didnt have the iratic idle when i hooked up the hondata) and the motor would idle higher or lower depending. pulse width looked good, ect was good, iat was good, etc..

 

Sorry my bad. I didn't feel like wasting my time sifting through all the childish BS banter that is in this thread to try and find what it is your actually asking about now. I also had a brain fart and forgot that the 95 is OBD1, shyte happens! I'm not trying to make anyone look dumb. I think I did a pretty good job of making myself look dumb on this one, thanks for pointing it out

Just ignore what I said and carry on as if I was never here!

 

ok thanks!

 

POst a Vid of this procedure, I want to learn more.

 

if u know how to take out a ecu u can put the s300 back in its place than plug a laptop up via a usb. that simple, u can download the software at hondata and play with it before u actually use it

 

Im confused, a simple question. You said your O2 sensor is bad and your getting a CEL indicating this? If thats the case none of the codes you posted to my knowledge are the O2 sensor. Atleast thats what my manuals say. I thought the O2 sensor was 41? Not trying to make an idiot out of you just asking and trying to figure that out and make sure the proper information is posted thats all.
