Hondata S300 problems

[Yoty]

ok guys colin put my motor in and that runs great.. thanks colin!!!

BUT: we couldnt get it to idle and now it doesnt even go. turns over but wont run. Even if i plug the ZC back in which due to the hondata trouble ive been running it on fine now desnt make any difference

Can anyone help

[timmiblc]

Got a laptop? Maybe plug in to the hondata and have a look at error codes?

[dazznz]

Yer check for error codes, and also check the tps and map sensors as these caused a similar problem with my car.

[Yoty]

thanks guys i tried all that already and the DTC code screens not showing anything. The sensors are pluged in and sending and receiveing signal

[Yoty]

ok so it needs to go back to speed source i think, as its not always communicating, sometimes there and sometimes its not. Its been at MC motors for a few days and they said its prob faulty. cuz its flashing a red light on the hondata chip

Not socketed correctly maybe?

[Yoty]

yea i hope it is but when i called down to ask about the problems they were real defensive aye, like its never happened before and sounded as though they believed it was the cars fault or wiring. but we have found on two seperate computers that it sometimes talks to the laptop and others it doesnt, and when u upload from the laptop it doesnt do it and realtime doesnt work either so yea.

using the same laptop everytime and the right COM port etc?

[Yoty]

tried two different laptops and the right com port. the other laptop was used by andrew short who as we all know tunes these units and he had the same problems. me managed to get it to communicate for 30 minutes whilst the ecu was on its side but then it stopped again

its an s300 hayden it uses USB so it should work fine on any laptop with USB support

oh yea, may be different than mine, mine is a.... some thing i dont know the name of but i use a usb adaptor that has to be setup.

[timmiblc]

Sounds like it's not socketed correctly, especially how it communicates only when it's on it's side

And whatever you do, don't download the map from the ecu to your laptop, copy the map from the dyno laptop to yours (via cd or something). There have been known problems with the maps after doing this, it somehow corrupts the map in the ecu 8O

Didn't happen with mine, but then again, neither did this problem

common hondata problems

Troubleshooting common s300 problems. Please follow all these steps.

1. Download and install the latest version of SManager here.

2. Check that the ECU has J12 (US) or J4 (JDM) cut.

3. Does SManager show 'Online' on the bottom left of the window when the ignition is switched on? If not see USB troubleshooting in the SManager help file.

4. Create a new calibration from File->New, adjusted only for injector size.

5. Can SManager upload the calibration to the s300? If you can't upload a calibration, it is the ECU socketing.

6. Can SManager datalog from the ECU? If you can't datalog, then switch the on-board datalogging off, clear the stored datalogs and try again. If you still can not datalog then it is the ECU socketing.

If you get this far, then the s300 is working correctly. Any problems now are caused by the ECU, vehicle wiring, sensors, engine or calibration.

7. Start the engine. Can SManager datalog? If not, check that the plugs are resistor type and the thermostat ground is good.

8. Are there error codes? If so, find and fix the causes.

If the datalogging stops at a certain rpm the cause is electrical interference, usually originating from the ignition system. Check that the spark plugs are resistor type and that either the distributor cap has a resistor or plug leads are resistor type.

Note that the LEDS on the s300 don't tell us anything extra over what we can determine from the steps above

Ian, you are officially my hero

Awesome info - saved it to my docs already!

[Yoty]

thanks for the troubleshooting guys but the ecu doesnt talk to the laptop

[Coupe-R]

But it communicated when the ECU was on its side>>?????

Sounds like an ECU electronic problem to me. Id check for dry solders.

Who socketed your ECU and installed the hondata S300. Sounds dodgy to me.

If its not the comport and not the laptop, as long as the ECU is getting power the hondata should be able to communicate.
If not id fault the hondata installation or soldering first. (ESPECIALLY IF IT WORKS SOMETIMES) this points towards a soldering or electrical problem to me

[vtec8 returns]

Are you using the same USB port all the time? My kpro only works on one of the ports (side on my laptop and not the rear one.

PM non vtec... he has a few more tricks and has seen problems with ecus not communicating with the s300

hey guys thanks for all the help. We are sending it back to speed factor for them to have a look as they fitted the hondata to the ecu. hopefully they can fix the problem.

the usb doesnt really matter which port on mine as ive only got 3 ports at the rear and they are all parallel nehow. the laptop picks up the hondata as hardware and it does come online but the ecu doesnt accept the upload as nothing changes.

We are stumped and as it hasnt worked on two different machines then im guessing something has come astray on the ecu

again thanks for your help and ill let you all know the outcome once speedfactor has determined whats what

Thanks rich

quite simply it is the cable that goes between the laptop and ecu.
I have come across the same issue with another car that had the S300 done at speed factor, using the supplied cable it didnt work properly and wouldnt upload a base map into the car properly.
I have a better cable which has inference magnets that you can buy from dick smith for about $2 each on it which works alot better. Once we plugged the cable into the car and uploaded the revised basemap the car ran fine.
Generally speaking if the cable is plugged in and is set to talk to the laptop properly through the USB calibrations on the laptop you shouldnt have any issues. It should say the ignition is switched on and is online. If it switchs to offline when the car is started then its an issue with the cable.
If it never says its online at all then you need to check the USB calibration and set that up in your laptop.. maybe re-install the software and USB calibration for the ecu again..

But personally just try a new cable with better magnets, also check that the USB cable isnt earthing on the case..

My biggest recommendation is to Buy a hondata through a dealer that sends the ecu's to hondata directly to be done, at least you know they are tested and installed properly..

interesting...

the ecu is on its way down to them as we speak hopefully, so we will see what they say. also the ecu when its talking to the car, you can go into information and it shows what model and number the ecu is but we havent been able to get that to happen (well thats what hondata said nehow). so we shall see what happens.

Its interesting that the usb cable makes a difference, i never bothered to check that as i figured as it comes online the cable must be recieving a signal and nominally the receiving signal is weaker than the sending one so i guessed it was ok

jeez and to say this was 'plug and play'

Wow thats interesting. I thought that the cable would have come from hondata? Isn't the cable just a regular USB cable??
Doesn't hondata have a verify option that verifies all of the Hex codes in the uploaded ROM with the file on your P.C. This is the best way to rule out any corruption in the uploading (putting) process

About interference and the likes, all of the boards have dotted lines on the PCB showing where to install filtering capacitors to rule out any interference between the rom and the rest of the ECU.

the capacitors wouldn't affect uploading a ROM i don't think. HOWEVER for piece of mind I installed all 3 or 4 capacitors that are supposed to be there.

Many don't install these, but they came with my chip kit so I put them in just to be safe.

Im guessing it wasn't a COM Port or USB driver problem as he tried two laptops, one of which is used all the time to tune S300 so he says?
Good luck, hope everything is sorted for you.
