After a trip on the dyno and a week of self-tuning, I have a list of questions. I'm a 2 year user of s300 with 25+ NA tunes, but new to flashpro for S2000.
I also know how to post properly, hopefully inducing replies by spunkster
and or hondata
.Serial number of flashpro: FP-S2K-US-30023
FlashPro Manager version: 22.214.171.124
Vehicle: 2006 Honda S2000
ECU: Stock PZX
Mods: Airbox lid off (don't flame, tuned this way), otherwise bone stock.
1.) It is my understanding that there is no need to to force open loop, and that s.trim and l.trim are compensated during tuning. I've monitored while livetuning and it appears that when l.trim is <>0, it does make an influence in lambda overlay. Maybe it's just my imagination. So... is the first sentance in this question true?
2.) Is there a way to clear lambda overlay like in sManager (control+L)? I loved this feature and it's gone. When I live tune the fuel maps, I want to see the changes without stopping recording and starting again (thus generating a large number of autosaved datalogs - a cool new feature nonetheless)
3.) Is there a way to show target lambda overlay values like in sManager (Shift + F4)? If I add or change load indexes, I have to flip back several times to settings to see what I'm actually tuning to (target lambda).
4.) Are there *any* differences between a "stock" uploaded flashpro config and a true oem untouched ecu? I thought I read that knock sensor sensitivity was reduced, to aide in tuning, even in the claimed "stock" configuration in FlashPro Manager.
5.) After 40k miles and no check engine lights in a bone stock 2006 S2000, after starting with a "stock" config with only two changes (ELD disabled and wideband input configured on ELD), I now have a DTC/check engine of P2A00 (air fuel sensor [sensor 1] circuit range/performance problem). Coincidence that this happened on day 1 of using Hondata? I won't rule it out since it was a service bulletin. So...does the "stock" flash take into factor the o2 heater delay described in the bulletin? Any other comments? DTC always
comes on while jake braking (engine braking) on the highway offramps. Datalog attached "06-21-11 P2A00 DTC at 25-30sec.fpdl
6.) I noticed +10 s.trim on highway cruising and no l.trim adjustment, coupled with a steady 13.4 ish AFR. This seems strange to me but could be normal. I'm used to near 14.5 bouncing in closed loop with s300 in my CRX. Is this normal? Datalog attached "06-23-11 Large s.trim on highway, no l.trim.fpdl
Thanks in advance,
