Hondata

Does YOUR car have to running ? ...on mine ...all I have to do is have the ignition key in the ON position, engine not running, and I can adjust TPS voltage.
if your's is like mine... just remove the TB so you can get to the screws, turn key to ON postion, adjust for proper voltage right at the ...

if you put your old ecu back on ... do your problems go away ?

how does this work? If i wanted hondata, i buy from a "hondata" dealer, and am i supposed to explain to me the setup I have on my car, then they will send me the appropriate base map???


Well ... yes .. and no ... the dealer you buy your setup from should be able and might be willing to send you ...

you are correct ... the check box is grayed out on mine too ... I had not noticed it until I read you post ...

Not sure if it is a problem though .. I have mine set to 9500 ... as I do not turn it much over 9000k very often .... maybe you could try changing it real low like 4500 ...and see if it ...

I never got any error code when I was having this problem ... probably need to investigate the code 43 closer ...

I've been driving my car the the cover off the ECU for months now ... And never saw any moisture on the board ... I don't think having the cover off could cause enough moisture to gather on the board to cause a cap to burn out, unless of course you are in a very, very humid climate.

ohhhhhhhhhhhhhhhhhhhhhh..............

HOW CAN IT BE AVAILABLE ... IF THE HONDATA PEOPLE SAY IT'S NOT AVAILABLE ?????????????????

Well .... I guess I just can't run the car in closed loop with the PLX devices O2 sensor ...

The car runs pretty good in open loop ... but it totaly goes berserk when I switch the closed loop .... and use the narrow band output ....

I guess I could rip the whole thing out of the car ... and see ...

Ok ... I switched the output on the PLX box from the wide to the narrow band output...

I put a toggle switch on the PLX box, so I can switch from wide to narrow band output.

But my car still goes grazy when I put the ECU in closed loop ... This is driving me nuts ....

Do I have to do anything ...

thanks Andy... I appreciate the advice.... I'll try it and let you know what happens ...
thanks again

I was under the impression that I could run this particular wide band O2 in closed loop ...

It is a PLX Devices O2 ....

Am I wrong in this assumption ?

If so, it would solve my mystery .... because I didn't take the wide band O2 out ...

First I turned OFF closed loop ... then I tuned my maps ... got my low speed fuel map near perfect and I have the high spped maps looking good too.... no real big discrepencies anywhere on the map ...

I am using a PLX Devices wide band O2 setup ...

Well .. after getting this done ... I smoothed ...

All you ned to do is call Hondata directly .. give them the serial number off your unit ... let them verify that you did indeed buy it from your dealer ... and they should be able to give you an unlock code, or offer some other technical advice.

When I bought my unit ... I had a similar problem ...
