Hondata

Hi guys,

My car has developed a wierd problem, there seems to be an intermittent missfire under higher boost that isnt apparant at lower boost, though nothing has changed withthe car and i havent had any problems previously. If the car starts to play up during acceleration and i change up a gear and put my foot flat down the rev limiter is active.

I have been able to datalog this problem, i can find anything that identifies the missfire from the datalog, but am assuming that the 2 problems are interlinked.

Datalog 'ok 7psi' shows the car acting normally at 7psi.
Datalog 'rev limit on gear change' shows the rev limit activated for no apparant reason.
The 2 datalogs labelled missfire are from when i was accelerating and the car was 'missfiring' but i cant see anything wrong with the log, maybe the injectors are cutting but the refresh rate of the datalog doesnt show this?

Any help appriciated.

lean protection 2 maybe causing the rev limiter, I'll try this out now. Any ideas on missfire?

Changed plugs and the dissy is under a year old non OEM replacement, maybe a crappy dissy?

Changed lean protection to 6psi and 300ms trigger time at 13:1 and it seems fine, now to find the cause of the missfire.....
