Hondata

I have the s200b with the launch and nitrous controls. Car is an SC EM1.
I recently went to the track and when I wanted to set my lauch rpm via the push-button, it failed to remember the desired set rpm. I used hondata's instructions to do it--which is how i've been doing it since i got this unit a couple years ago.

I checked the wires to the ecu, clutch switch and blue box and everything is secure. The CEL does flash when I push the button once, for launch rpm. I rev to the desired rpm and tap the break pedal. The CEL stops flashing and that's supposed to be it. Turned the ignition off. But once I try and see if the launch rpm is set it does not remember the rpm. And yes I have the clutch pushed down. I tried it in gear and out of gear, no luck. And yea I'm going ZERO mph.

Also the full throttle shift doesn't work anymore. I found that out going down the 1/4. I don't have a laptop so I can't get into the ROM software. Could you completely disable the launch controls and full-throttle shift via the ROM software so that you can't set the rpm's via the push-button anymore? I recently got the car dynoed and maybe it got disabled accidentaly.

I've also posted this on Honda-Tech but I realized that I should post my problem here too.

Any ideas? Thanks.

Have you tried resetting the Interface box per the instructions? Also check the operation of hte clutch switch with a multi meter and make sure that the continuity changes.

I found this link:

The explanation was unclear to me. Does this fix apply for my car?

I'm running a p28 ecu with harness. The car is an obd2 '99 Civic Si.


And no, I haven't checked with a multimeter yet since I can't get a hold of my friend. Thanks.

Unless you have an ecu witha built in adapter harness this does not apply to you.
