ive been having problems with ecu or harness. the harness is a wireworx harness. I sent both out to get looked at and both places said they worked fine. I put in them in back in the car. it worked good and the next day the ecu is blinking red and I get same crazy numbers on the display window with the car off and the numbers don't change with the car started. these are the same numbers i got before.
tps -13
map -29.9
ect 302f
iat 302f

 

 

u must of knock hondata out of place, open it up and push it back in.

 

 

Update your SManager software, load the calibration that you want to use, re-save it, upload it into the car, switch the key off and back on and then hit the lightning bolt and see if your data stream finally works.

 

I just noticed you stated that it worked fine for one day and then didn't work, so my above post is likely not the issue. Check your engine harness grounds.

 

ya I checked the grounds. if it was the grounds I wouldn't think the fuel pump would kick on . I can start the car but it runs like ****.

 

Have you tried moving your s300 board into another known good socketed ECU ???

 

The newest version of smanager has a few glitches. Mine does this sometimes too, with multiple known good ecus and s300 boards. Try plugging and unplugging the cable into the computer a couple times, pausing for a few seconds between each. And when you open smanager, wait several seconds before uploading the map, then toggle the ignition, then wait several more seconds before clicking the lightning bolt.

What version s300 board do you have? aka what color is it? There's a chance the s300 might be going bad.
Also a possibility is capacitors in the ecu failing.

 

its v3 white. im waiting to borrow my buddy's s300.
