Hondata

Hey, i have a wierd issue here.

ecu edm p28
s300 board #12465
latest version smanager
1994 eg6 civic
engine b18c6 stock
walbro 255 with fpr
stock injectors

Issues:

-More than half the times i turn on the ignition it doesnt do the check engine and the pump doesnt pull altough the engine starts and runs normal
-From time to time i get a cell with the 13 error code " barometric sensor" (wich i believe it doesnt exists in edm civic) and the engine runs like crap, misfires, lots of gas....but if i switch of the ignition and turn it on again the cel goes off with out erasing it and the car runs normal again

I installed the s300 in another virgin p28 and it does the same
I changed the main relay it doesnt solved the problem
I tried the ecu in another stock eg and it still have the same issues mentioned above.
I uploaled also the file with two older versions of smanager, 1.4.8 and 1.4.1 with no sucess

Now im 90% sure that the problem is in the s300 board or a software bug, it doesnt have anything to do with the car nor the ecu itself.

P.S. I have installed surelly more than 50 units of S300 boards with no troubles and hundreds of socketing ecus so please dont doubt my skills. :)

From HElp, about, what version of software are you currently using?

1.5.4

Download the most recent version of beta software from our website (released yesterday) and give it a try.

Ok i´ll give it a try!

Tried 1.6 version...it didnt work. Should i send you the board to analyse?

Who did you purchase this s300 from?

I have the exact same problem. Car always starts and everything runs like normal but the car doesn´t always prime. More than half the times it doesn´t prime, and that´s very annoying.
I will try the new version of Smanager too and write back about this problem.

Well the company i bought it trade ir for a new one and i believe hondata people did the same to him. I´ve assembled a dozen more after it and not a single issue, i guess it was a single bad unit. Thanks.

Do you have the Barometric Pressure Sensor disabled in SManager?

edit: i see in the calibration it is disabled... also, are you able to download the calibration from the ECU and compare it and make sure everything is getting sent to the s300?

What do you mean when you say prime?

I have the same problem... The engine light is on, already tested the board on another ecu, idle on 1500rpms and I don`t know what more to do... Already sent email to suport...
