this is a software for a laptop right? I went on matco tools website didnt find anything for obd2 software or even the plug and the usb cable...you got the part number?

Mikey21

could you give me some more insight? of why the data wasn't applicable to your problem? like it was incapable of providing you with the info you needed? it lags?

beecee18

great minds think alike.

To be honest Unless its a code that overfuels or creates drivability problems.
With OBD2 I wont even reset the ECU, I just patiently wait for 40 keyed cycles of not detecting a fault then it just goes away.
I wish they had flash memory in 96-2000 honda ECU's cause there resolution is greater, And would make tuning for the enthusist much easier.
And the ecu does so much work for you when understood correctly, its like having the best second opinion around.
But there just simply isnt

beecee18

No its a handheld, I like to use it to check for readyness for smog customers, and to determine which protocol, OBD2 or CAN
heres a link to the bugger. dont see a reason to want a laptop software type/ this matco comes with powerfull software that after diagnosing the car you can plug it into your PC, And matco gives common fixes for the codes, and you can transfer data graphs of live data on your PC.

I got a obd1 p72 ecu ready to be chipped. so what your saying is if I put hondata s100, neptune, and i'm not sure if chrome has the capability to hook up to a lap top but i'm think hondata and as Bix VT said Neptune is also able to be hook up to a laptop through usb right? So If Chip my ecu with Neptune, hondata s100 and possibly chrome, I'll have the features and capability of real time data logging, freeze screen, dtc check and clearing them, pending dtc's, and other features correct? so they come with a software and obd2 port and usb cable?

Mikey21

Demon board + Neptune what are it's capability's? demon boards the software and neptunes the chip right so I assume it comes with the obd2 port and usb cable?

Mikey21

whats 40 keyed cycles? LOL and I think aem has one of those ecu that comes blank and you can upload, and reprogram the parameters you want but this is only if your car has a **** load of aftermarket stuff though.....mmmmmm not planning to go ***** out with this build....... hondata neptune or chrome it is....lol

Mikey21

it turned back on, p0171 and p0170 lol woooooo!!!! dropped two codes LOL autozone guys thinks it's the Pre o2 sensor(Before the cat)....don't know how to test that...should I replace it? I think i'm gonna havet to...

Former User

Start by replacing the fuel filter and checking for an exhaust leak near the primary O2 sensor.

Mikey21

I ordered the fuel filter but i'm sure i dont have an exhaust leak, only exhaust leak was on the headers and was a small little crack and i wielded that....i'm going to torque the head down and intake mini i have everything to do it but a 0-250 in lbs torque wrench for the intake cam rail and valve cover nuts. I already go a torque wrench for the rest 10-75 ft lbs....If torquing the head bolts, intake mani and new fuel filter don't fix it, then I'm gonna replace the pre O2 sensor and get the gauge to test my fuel pressure from...god know where....I don't want to buy it but can't seem to find a place that got one for rest so I guess I gotta ****in buy one hopfuly it's not the evap system cause i have no clue on how to **** with that ****...but if it is that, then here a golden opportunity to leran out of my expense

beecee18

OBD2 port becomes useless when you convert to chipped OBD1 ECU,
we have no support for tuning OBD2 ECU's, some have chipped but its known as a complicated process supposedly

I think you can get a socket in the OBD1 box for datalogging?

beecee18

Evap is seperate and there is a seperate monitor,

40 key cycles is putting key in-driving-shutting off and removing key.

If the motors never been apart, or you are not expeirencing problems from something that is consistent with everything needing to be re-torqued, Dont do it!

Evap is gay and easy, and stupid,
and created by hippies lol

jbpnoman

That's exactly what I'm talking about. With most tuning software, you can solder in a USB header for datalogging and diagnostics, making the lack of an actual OBD port moot. It obviously can't be used to reflash, but that's just about the only thing it can't do with the right software.

Mikey21

LOL!!!!

Mikey21

So cut the wires on the obd2 plug in port on the car and but splice in on to a usb wire?

Mikey21

ok i took off my pre o2 sensor i think it's good...not sure, how can you tell if it's bad? and waiting for the fuel filter cause the gave me the wrong one...and yeah my head was off at one point cause i put a ls bottom block in, so could the head be loose and be causing the lean codes? do you guys think its a good idea to check my fuel pressure?

jbpnoman

No. No. You either aren't reading, or you aren't comprehending.

You can solder a USB header into an OBD1 ECU. That allows you to run a USB cable out of your ECU straight into a computer for datalogging and tuning.

A USB header looks like this.


The cable you would use looks like this.


You cannot tune an OBD2 ECU. You can datalog through the UBD2 port, but you won't be able to do anything with that information. By swapping to an OBD1 ECU, your OBD2 dataport will no longer be functional. This USB cable method gives you an extremely powerful alternative.

beecee18

And this is my gripe

any info you are pulling for datalogging from the OBD1 box is factory OBD protocol PID's. So it is not more powerfull, they are just manipulated descriptions/values/measurements of actual OBD PID's so the user can understand what they are datalogging easier.
The resolution and speed of datalogging remains the same as a scantool honda would use back in the day on OBD1 vehicles.

beecee18

Honda ecu's from 96-2001 can not be tuned for one reason and one reason only.
they have no flash memory address in them (non-flashable)
every other manufacture did though,
its 1 of 2 things I think honda failed at, as they were just happy with and found no reason to change.

1 no flashable OBD2 box, which is stupid as hell seeing how TSB reflashes cannot be applied due to changes in fuel/TSB's/ect. so you are just stuck with poo

2 mechanical distributor with 1 coil, I mean come on here, distributors after 96
this is simply one of the most primitive things you can find on a honda all the way up to 2001, simply a joke.

my only 2 honda gripes.

Mikey21

lol I was reading but not understanding lmao i was thinking of something totally different when you said usb header lol! but this is sick where can i get the usb header? what brand?

Mikey21

okay i replace the fuel filter and pre O2 sensor and reset the ecu now just gonna drive around for awhile and see if i fixed it. I found some oil on my spark plug threads and got a valve gasket set gonna slap it on this weekend and i found the valve cover studs is striped on top side where the nut goes and wont tighten down. two are bad forsure gonna check the other ones this weekend to....

Mikey21

what? other manufactures can mess with their ecu like reprogram them, like how we do with our obd1 ecu but they can do it with there obd2 ecu's? If so...i didn't know that..lol I though ALL obd2 can't be flashed....hmmm..... lol

jbpnoman

eBay, all day long. As for how to actually install one...that'll take a lot of searching. I just had HA motorsports do it for me when they chipped my P28.

beecee18

Yes look into mitsubishi and subaru ecu tech,
and many others.
they are able to be reflashed with the use of affordable hardware and opensourse ecu reflashing software created by guys like you and me mimicking the manufacture reflash protocol.
The options are endless and simply impressive and better then anything hondata has ever done for the honda community.
And not as it is there fault.
Honda ecu's are just to simple and to put it short suck!
Honda has always short chopped their compliance with OBD since day one, and they have even gotten into legal problems because of it.
With OBD1, Mechanics that are tech savy will tell you hondas expecially OBD1variants are hard to troubleshoot cause you basically have to unplug the sensor or smash it with a hammer to make an engine light go off.
basically have to have an open circuit for it to reconize a fault.
Honda has been in the courtrooms and sued many times for this, as they fail to meet the rquirements on many occasions with the OBD protocol.

So just like flashpro for the K series,
but with free software, and a flash block that plugs into the OBD2 port, you datalog, pull the car over reflash, and rinse and repeat.Giving the average user like you and me the opportunity to tune our own vehicles on the same streets we drive our cars on everyday.

I DO NOT know why, and I am trying to find out why there is no other honda enthusiasts that will reverse engineer the k series ecu to provide opensourse reflashing options for the more techy guys like suby and mitsu.
My only response is the culture of these enthusiasts are simply different. Instead of geeks, and professionals that love the AWD cars due to the price of them alone being 200-500% higher then your average honda.
You get the stereotypical honda guys
gangsters
theives
racing/stealing crews
really young children
ect.

Mikey21

Bro! I think I found the problem! Tell me what you guys think, ok, I'm running a SI obd2 ecu for LsVtec and that's what making my car runs lean cause it's not capable of running a bigger engine, I need to chip my p72 ecu I bought awhile ago and tune it.... I am I right? lol I change the pre o2 and fuel filer and still runs the same. I think it the ecu not being capable with LsVtec!
