s300 troubles.

[iksan12]

Good morning. Few days ago my car started to react strange , while driving the check engine light would come up and the engine will start bog down and sputter. My vehicle is 93 Del sol Si. I have been using s300 for probably 2 years now with no issues. Things that i have done when the problems happened are replacing all the caps on the board its a P06 ECU. Reflowed all the connections on the 28 pin male pin headers to the board. When i unplug the ecu and leave it for a bit and plug it back in the 2 led on D3 and D4 are green and the car works fine for like 5 -6 minutes then it starts sputtering again but the hondata led's are not working or just D3 led is green. When this happens Check engine light comes on too. I tried connecting and read the codes but there is no stored faults. I did check all the connections to the hondata and ecu everything looks fine. Maybe my ECU is gone im not sure... Any input is appreciated. Thanks guys.

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

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

Hello , the serial number on the board is : S300 61421 ( hologram sticker )
There is another number S300 III r16. Im running the latest firmware i literally updated it yesterday. Not sure about numbers because i cant connect to the unit at the moment. Just to add something - When the LEDs on the board are not working the vehicle still primes the fuel pump but does not start.

Do you have onboard datalogging enabled?
