First time with KPro
Posted: Tue Jun 25, 2019 5:37 am
Hi all,
Got my first K series not long ago - K24A2, swapped into a Honda Insight. I'm using an RSX harness, Type-S ECU, Accord TB for cable conversion on RBB intake. A couple of questions:
1) I'm having trouble getting my idle right. It seems the longer the car runs, the more I need to bump up the idle valve duty cycle. A setting that's "just right" after my 30 minute commute and catches the falling idle right around 900rpm will have the idle dipping precariously low upon throttle release after a 4 hour trip (3-400rpm). Set it right after a 4 hour drive and at the 30 minute mark, when I press the clutch in, idle will shot up to 2000-2500rpm, and is even worse fully cold. What am I missing? I haven't touched 0 degree cam ignition timing yet.
2) I'd like to get A/C switch input working. Multiplexer is disabled, VTEC pressure switch is disabled, Alternate A/C switch input is enabled. I re-pinned things so the car's A/C switch is going where it's supposed to (surprisingly the A/C switch in the Insight is the same color as the VTPsw in the RSX), and verified when I cycle A/C I get 12v and 0v on the line. However, in KPro I never see the ACSW sensor activate. If I re-enable VTP, toggling the A/C causes VTP to toggle. What am I missing?
3) Cold starts (in summer) take 5-8 seconds of cranking. Fuel pressure is correct at the rail. I'm guessing this is cranking fuel trim? It fires up first crank when warm though. I may try playing with this value, but what else affects this? Should I uncheck "disable ignition retard when the engine is cold" ?
4) Let's say I wanted to run a bit lean at low load/RPM cruise. What values do I have to change? I know I can change target lambda in the target lambda table, but in Parameters / Closed Loop Advanced there are also Target Lambda Limit, Target Lambda ECT Low and Target Lambda ECT High. I haven't yet finished tweaking my fuel tables so I haven't tried leaning it out yet, but why are there so many places one can set target lambda?
Expanding on 4, if one sets target lambda to (let's say) 12.5 AFR in the WOT cells, why would one want to use WOT compensation tables and not just set it in the normal lambda tables?
Can someone take a look at my kal and give me any tips/advice?
Thanks!
