You have to cut the wire to the switch or every time you hit the brakes you will datalog.

Here is a link to the cruise control switch install. http://forums.clubrsx.com/showthread.php?t=714476

I checked the main grounds and found the battery to transmission attachment bolt semi-stripped. I had my transmission out last year and the mechanic used an impact for EVERYTHING. I made a new and more robust stainless steel ground bracket that I put under the 12mm nut to the transmission bracket ...

I have it in open loop. I am still tweaking the fuel.

I have an 8 gauge ground wire that goes from the battery to the throttle body, to the intake manifold (same bolt where the main ecu is grounded. to the passenger side motor mount, to the valve cover, to the fire wall near the ecu. http://www ...

Here is a datalog with the 'Fix Honda tip in bug' under 'Gear Comp' button checked. You can see it everywhere. While holding the throttle steady, the ignition dips from 45 to 20 every few seconds. Is this normal? If so, why?

[quote="Hondata"]... To fix the ignition dipping, select 'Fix Honda tip in bug' under 'Gear Comp'. However, you should fix the about problem first before worrying too much about the ignition.[/quote]

Most of my datalogs already look like the "Corrected tip in retard behaviour". My question is, why ...

I figured the ECU was not getting power so I checked Plug A Pin 2 and 3 for voltage. That was good. Next I checked pin 4 and 5 for ground. Eureka, bad ground. A short search later, found the loose bolt and all appears good with the world.
Great advice gang, thank you.

That sound like good advice. I will start checking the wiring, even if I can not get it to run. I figured some of those other issued may have been a coincidence. The car has run so reliably and it so meticulously maintained.

What do you think if the timing issues? The random dips and idling nowhere ...

I have had two different error codes shortly after the upgrade.
P0137 Secondary 02 Circuit Low Voltage and
P0505 11-139 Idle Control System Malfunction
I have not had these since working on the idle control valve.

The complete list of engine modifications that I did years ago include, Jackson Racing header, metal substrate high flow cat, Borla catback

I have done a proper dyno tune and do make more hp with the high cams at only 3k. Lately it seems to be running rich. I had the fuel values looking really good ...

The bar code on the daughter board is 0500813 The board has Rev. 13d on it.

I replaced the stock PRB intake manifold with a PRC. The PRC is from the Type R and there is almost no difference between the two. After cleaning the idle valve and it did not seem to work, I did try an idle valve from an ...

I immediately after getting my ecu back from the upgrade, I had some idling issues but figured it was a coincidence and cleaned the idle valve. The idle still jumps up to 1500 now and again ...

That would be a great thing to be able to do.
I hand write all the recommended changes on grid paper. I like to compare four or five datalogs before making changes because I get conflicting suggestions.

[quote="SIKCIVIC"]Which wire on the ECU did you connect to to enable/disable the onboard datalogging?[/quote]

E22 White and Black

I ran the wire from the cruise control switch to the ecu as mentioned avove and it works as planned. My K-Pro is not yet upgraded for onboard datalogging, but I can see the BKSW on-off radio button operating while I datalog with a laptop and switch the cruise control switch on and off.

Now all I ...

The #2 pin (LT Green Wire) on the main cruise control switch has a switched 12v output. From there it goes to Pin#4 on the brake pedal position switch and the #13 pin on the cruise control unit. I think you would snip it and run it to E22.
