the light on my s300 turned red, help!!!

[turbo_hulk]

i have a 95 integra ls with hondata s300, it worked great for about 8 months then one day i started my car
and it runs like shit, wont rev past 3k rpm. the led light on the ecu thats normally green is now red, my check engine light is on
wont let me check the code nor can i get the ecu online in s300 manager, what does this mean and is it fixable?

Sounds like how mine is. wont rev past 3-3.5k,check engine light, and i cant get it online either. i'll have to check what light comes on on my hondata board. Maybe were having the same issue.

actually mine is a solid green light, but the rest of your symptoms i have

send an email to support <at> hondata.com.

include your serial number that is on the s300 board inside the ECU and a description of the problem

Im having the same issue just cant figure out what it could be though turbo_hulk did you get yours fixed

After updating to 2.0 I am still having the same problem car starts fine green light is on but after the first rev or car runs for awhile the red light comes on. The car gives no check lights or the ecu gives no codes. If I let car sit for 10-15 min its like it resets and starts fine with green light then after first rev back to red light and low power on revs wont pass 2000 rpms. Any Ideas I also checked the map, distributor, injectors, all fuses and sensors that i could think of...

Try the s300 in a different ECU or try the s300 and ECU in a different vehicle.

Tried s300 and ecu in another vehicle same results. The only new findings is check engine flashes when the accelerator is pressed then turns off but still will not give any codes.

Try this, upload calibration that's come with S Maneger. if you have b18 motor just upload the B18 Calibration, after upload the calibration from S Maneger REUPLOAD your own calibration. See what happen..

Wow. I'm having this exact same problem. Will email support shortly.
All of a sudden the car doesn't want to start. Will connect and Datalog, however, both the red & green LEDs flash very quickly while connected. Disconnect and it's solid green. I can get it to start IF I give it about 40% throttle, but it can't idle on its own. It won't rev past ~2,500 RPM and the CEL flashes quickly each time it hits this rev limit.

Things I have eliminated by testing with spare parts:
ECU
Map sensor
Distributor
Plugs
Wires
New calibration

My buddy let me borrow his new S300 V2, but since it hasn't been registered yet, I can't do much with it...
