Ok after following the tutorial to a T, it starts but now I have DTC 0300 Misfire issues, idles horribly and stubbles when revved...will post current tune. in a few minutes.

Beer,
- Enter values for those out-of-range tables/parameters.
- For NO2, use A0015 to richen, and A0016 to retard.
- Closed loop is enabled and MAF enabed... is this how it was running prior to going to COS5...?
- During idle/warmup, open loop AFR will be very rich, but at high map values it will be too lean, see first pic; should look more like the second pic.
- Post a few logs.

I think I have another issue as well, I think I knocked the MAP hose off running a FPSS harness, let me check that as I loaded a tune that worked previously and the MAP at idle is 40-70 kpa and very erratic.

Well this sucks, pulled the intake off, and the hose was fine as well as everything else...something is just not right...

If you copied your VE and and IFR tables (and all the other tables)...Originally Posted by Beer99C5
then it's probably due to either (or both) of:
- the out of range values need to be made sane (the displayed value is the max, but the actual value is out of range; enter max-1 or some sane value, save and do cal-only flash).
- B3647 is very rich at low RPM (something like AFR 9)... this table you have to make look like the pic in my earlier post... flat at low/mid MAP, and then ramping up to high MAP so that it's sufficiently rich when throttle is wide (and MAP is high).
"...I hate when that happens..."
I will that next Joe, I am bolting up the intake (was not the MAP hose, as I had hoped)...
On the up side my intake/fuel rail removal/install skills are getting quicker :lol:
