Hey, I'm looking for some tuning advice for my chipped SMEC running the Ostrich 2.0. I've been messing with MPTune for a few weeks now and can get the engine running, driving, and boosting along happily, but I have a problem with my idle being quite rich and I cant seem to figure it out. From what I've read, I'm not the only one with this issue, but I also cant seem to find a solution.
This usually happens on first cold startup (I know, I know, cold startups are supposed to be rich). I should note that this is a Boost Button cal that I found online. Ive been modifying it to fit my needs, but it seems to run extremely rich on initial start, and stays in the mid 10's all the way up to operating temp, at which point it appears to gain into the 13's and stays there for multiple fan cycles. I have uploaded a stock dodge tune which brings the AFR's up gradually and then levels out at a nice 14.7-ish.
I have uploaded the boost button tune after a warm-up and had it run at a quality 14.7 which is weird that it wont do that on its own....
I'm just curious what parameters I can change to try and level out these idle AFR's.
Things I've tried:
- Modifying the FuelColdEnrichmentCurves (A,B, and C)
- Modifying the Curve Hold times
- Modifying the FuelStartFromCoolant
- The StartFuel From Temp
all of which seem to do absolutely nothing, which Im really confused about..
The only table that actually seems to change anything is the PumpingEfficiency from RPM, which takes some drastic changes at idle RPM to change the AFR.
Is there a secret table that I'm just not seeing? or am I modifying these tables in the wrong manner?
I was also thinking about maybe taking the startup and idle tables from the stock tune, but i'm not entirely sure how to do that, or which tables to snag.
Any advice would be really helpful to try and get this working, or even someones tune that may be a better starting point for my, into-to-tuning self. Thanks!
Also! Off topic, if anyone knows a good how-to on getting the antilag options to work on the Boost Button tune that would be awesome. The website just says that its do-able, but not much more.
Because I'm still a 4 year old at heart
