Hondata

It could be the power source.


No - Turned out to be a collective of issues. The power source was fine, but the supplied "clip" that plx gives you, obviously seated well within the PLX box. The issue was that the wire that reads the wideband was ..... not plugged in all the way I guess you could ...

Nice cool night -


Things that I found were wrong - Bad sparks, one bad injector, timing was not correct. Dizzy was almost fully advanced.

Followed the simple timing instructions of rotating the dizzy to where it ran good idling, then made a mark, rotated (intake side) till engine idle changed ...

I'm having a similar issue and found this thread while searching for answers. I have good power levels at the ECU, but changed to a chassis ground. The problem I'm having is after about 20 mins of idling, the AFR drops to 10, and so does hondata's AFR reading.

I have a Gen4 PLX Wideband, LSU4.9 ...

Long time no words.

- Turns out I had a bad alternator, and my timing was off.

2. Sync Timing
3. Definitely drive a little - tune a little - repeat.

Did more testing this week on the previous upload : Failed and nothing but trouble.

Started fresh with the Basemap for a P74 - Clunky and didn't idle well.
Changed to p72 Basemap - Rough idle and needed little adjustments to the low speed fuel table. Followed the target lambda overlay, and adjusted ...

First attempt at tuning took a while. Tuned a steady idle and doesn't sound like a subaru.

Took a few data logs. - Any adjustments to get a smoother ride to 40mph on the low fuel table?

Will post more later.

Had to zip one datalog.

Hi all, trying this on my own, and will be taking data logs.

What I have: 95 Integra b18 lower, vtec head (1.6 I believe)
Looks like adjustable cams gears, but not sure about the cams.
Skunk2 Intake and CAI. PLX Wideband, an 4.9LSU o2 sensor and wired up/working with P75 S300. Getting good ...

Got ya. I just found my map for my specific build, and waiting on new 550 injectors.

@ Calibrated - I will be doing the same here as well. New to the thread but dialing in on this one, so I don't start a new thread :-)
