Hondata

Hello,

I recently got a KPro for the 2005 EP3 installed and I've been playing around with tuning it, however I have something odd happening that I can't quite account for and I'm not sure what I'm missing.

Specs of the car:
EP3 K20A3 (stock block and tranny)
DC Sports Racing Header
Invidia N1 Exhaust
Injen CAI (new revision)

I'm currenting using the civic K20A3 high octane map as a starting point, and was tuning fuel based on that. I've gotten all the kinks worked out it seems, however at 6600 RPM during a 3rd gear WOT run the AFCMD goes from around 12.6 to 11.2 - 11.6 range.

I'm attaching the current config for the car and the last three data logs I did, all in open loop. If someone has any ideas on what I'm missing here, I could use the advice!

guess it doesn't like zip files - here's the datalog from the last session I did

This is something that the ecu sometimes does after repeated long wide open throttle runs. It is a built in feature of the ecu to help protect the engine from running too lean on repeated high rpm runs.

Okay, but otherwise it should be okay to take to a dyno to start playing with the timing and cam angles? This shouldn't cause a problem for that? The reason I ask is that I've done several runs in 2nd gear and I can't get it to drop like it does in this run, which I seem to always reproduce in a 3rd gear run. Thanks for the response!

You should not have any probelm
