Hondata

for some reason after i put a hondata system into my 00 ls, my voltage is is dropping like crazy. when i first start the car its at 14.6 then after driving for alil it goes down to 12.8 and stays there, reving the motor doesnt do anything, but wierd thing if i turn off the car and turn it back on it will go back to 14.6 but again after driving it alil it will drop back down. does anyone know whats wrong with this ecu? i know its not the alternator cause i ran a test and swaped one out and both still works fine. this is starting to really bug me, so if anyone has an idea on how to fix this let me know please!

What kind of ECU and ECU conversion did you use?

i am not to sure, i just asked for a s200 for a ls, i do know that there was a vtec setting they had to turn off

What I meant is that if I want to put an S200 in a 96-2000 car you need to replace the ECU. Where did you get your ECU, S200, Hondata.

i ordered it from dynospot racing, that orderd it from hondata. would the wrong ecu mess with the voltage.

I know this thread is old, but I am having the same problem.

Did youever find out what the problem was, and fix it?

For me, my car was doing the same thing. All I did was disable the ELD in the software and it fixed it.

ELD = Electric Load Detector
