Hondata

I have been having issues with my s300v3 i threw a solid cel light. so i started freaking out because i took the car for a drive the night before and it ran fine. no codes or lights. i figured the p28 might have fried so i bought a new s300 ready ecu. after swapping the s300 module over nothing has changed.

s300 serial# 374545
p28 ecu 2 one old and one new.
95 accord lx
h22a turbo
.57 trim
1120 fic injectors.
car start but dies unless you hold the throttle. i am wondering if its the injectors because after install the car started acting weird a few days later. it had erased my tune and wouldn't log anything. so i turned the on board logging off and figured i would just use my laptop. it ran fine until the day it stopped working with the logging off.
i will post the calibration and the log of it running rough when i get home

What is the error code?

it doesn't show one on the hondata app or when i plug into the usb. i tried to get the ecu to flash codes but nothing it stays a solid cel

That is not a valid serial number.

From Help, About, what is the version of software you are using?

What is the serial number that is on the s300 board inside the ECU?

What happens when you try to upload a calibration to the ECU?

My bad the serial number on the unit is # 37545
It will upload the calibration to the ecu. i keep the software up to date on my hondata.

I just went out to go test the uploading of calibrations and it uploads. after a few seconds the calibration is not showing yup. one of the LED lights is also flashing red.
Software version is V2.5.5
i pulled the unit out and connected it without the ecu it said the bluetooth hardware failed with a red X

When you say the calibration is disappearing...where is it disappearing from?

the calibration is on the s300 then i turn the key on to start the car and the calibration screen is blank.

Thanks for the help SPunkster. I ended up Find the problem. My calibration was corrupted, i uploaded the older calibration and it fired right up.
