Hondata

My friend Matt did a nice write up about diagnosing this problem. It may be a coincidence that it started when you went to a newer version of the hondata software. The link below should help you determine if it is mechanical or not.

no i have not checked that...i will...
it just seems so unusual that it'll occur...
do you have to do that when you install hondata for some reason?...
i'm trying to understand how it affected it...

i also did a 4min cruise and at the end a 2nd gear pull...
it's not the greatest but it's a start...
help with the rolling idle...it's annoying

i did a erased ecu log and after calibration upload
here are the logs

just to mention, when i erase ecu, it'll idle but lean lean readings. way over beyond readings (19+ A/F)
even disconnecting iac did no change. once i upload any calibrations in, i get the rolling/surging idle
here is a log of it from cold start til rolling idle
i hope i logged it right.
i will also ...

it worked before i stupidly deleted it. now i go and download it again, it no longer works. i can download it and have it set to go but when i double click it to open, it tries to open and just goes away like somethings missing. no window even pops up at all. i just see the icon come on and go away ...
