i recently installed and tuned my s200 hondata. everything seem to run fine, however the cel came on. i jump the ecu to check the codes but the cel light doesnt blink. can anybody tell me whats the problem is?

 

normally when it doesn't blink it means that something is wrong with the Ecu or one of it's components.

 

if you are running hondata reburn a new chip with your present tuned program and reinstall it. It happens when the chip doesnt have a good contact in the ic socket. One time i launched my car and i got a solid cel i couldnt figure it out so then i just did what i explained above! good luck let me know how it goes!

 

I installed my S200 last week and I had the same problem. Turns out I needed to disable the knock sensor in RomEditor. Disabled the knock sensor, no more CEL. Hondata also recommends cutting J12 with the S200 system.

 

where is the j12 exactly? only the tuner can disable the knock sensor?

 

You have to have RomEditor and a pocket programmer to burn the chip, if you want to disable the knock sensor. If you don't, yeah, you need the tuner to do it. Look at the installation instructions on Hondata's website-there is a good picture of the location of J12. It is on the opposite half of the PCB from the 27C256 chip.

 

thanks i wll check that

 

does the solid light do anything to performances?

 

My car actaully ran o.k. with the CEL on, but it drove me nuts.

 

ttt

 

ummmm... update? did you check the KS, J12?

-PHiZ

 

i cutted the j12 and now my car runs funny. it shakes and bogging?
do i have to cut it or take the whole j12 part out?

 

Just cutting it opens the circuit, you don't have to remove the whole thing. Get to a tuner and have them dial in the Hondata-who knows if you are running too rich or too lean without a wideband and a dyno?
