hi, ive just purchased the hondata s200 with p28 ecu off someone it was tuned on the same motor as my current motor right now. plugged it in, everything worked fine but i just noticed that, there was no launch control anywhere.
For a problem like this you'll need to take to to the nearest Hondata dealer to have them take a look at everything as it could be anything at this point.
email support at hondata.com with the serial number on the interface box to find out what options it has.
theres no hondata dealer around here but i called and they said it costs 65 bux to send it to them and have them take a look at it. but i wanna know would it damage my car if i drive it like that (led flashing slowly)?
ps: can i try to change the interface cable first?
Yes you can try changing it. It is always possible that when something is not working properly that you can damage the engine. The dealer needs to use the process of elimination to determine where the problem is.
where can i get a cheap interface cable? and also is it fine if i drive with no hondata blue box connected to the ecu? but that only allow me to rev till 4,000 rpm.
The red LED on the Hondata interface is blinking, the engine check light is off, the car runs
normally, or rich for cars with bigger injectors
Likely causes:
• The stock ROM is installed (see Appendix 3)
• J1 has not been installed (OBD I only)
Fix
• Replace with a Hondata ROM
• Install it as per installation manual
Ive searched around and came up with this, its similar to my problem. but can anyone tell me more about how to fix this? like replace with a hondata ROM? and how do i know if i have a stock ROM or J1 has not been installed?
