I just ordered Binary Editor + EEC Analyzer, and a Quarterhorse yesterday.
I plan to use it in my 2000 SE. I have an NPG mailorder tune running right now (flashed with xcal3), and hope to improve it.
My NPG tune was written for the original 2.5L, which has since been replaced with a 3.0L. I never heard back from Joey about my datalogs, so the tune was never tweaked accordingly. It did run the 2.5L well though.
The tune accounted for:
- 24# injectors (was planning to experiment with e85 at some point. prolly still will.)
- downstream O2 delete
- IMRC delete
- plus what ever NPG may have optimized for my mods list: Headers+y-pipe gutted LIM SVT induction, 91octane (best I can get at high altitude), etc.
Now that I have the 3.0 in there, It runs well, as long as the weather is nice. On cold days (below freezing) it pings like a M'er F'er until idle slows down. Wideband reports ~16 AFR while pinging. It still idles fairly smoothly, considering all the knocking going on under the hood. If I try to drive it, it will hesitate when releasing the clutch. Once it is partly warmed up (depending on how cold it is, maybe 30-60 sec.) it runs great, and AFR drops to 13-ish at idle. Once it is warmed up completely, AFR hops around between 14.3-15.6 at idle.
I'm assuming this is due to the tune thinking there's still a 2.5 under the hood, and the O2's haven't come up to temp yet to correct the fuel. I was hoping that the ECU would learn a new cold start strategy based off of the running strategy, I don't see any evidence of this happening though.
Also, even thought the engine runs well, It has no balls. I did use the 3L cams for some stupid reason, which puts the (very narrow) powerband where it should be for an automatic car. I also get poor fuel mileage, like 200 miles / per tank. A little bit of dataloging shows the spark advance sits firmly at 15 deg (unless letting off the throttle of course, were it hits 39 or so). While driving around for the past few thousand miles with the 3.0, I have witnessed a few times, where under hard acceleration, it suddenly pulls very hard, but only for a second or so. I imagine the timing finally advances some, but I haven't been able to catch this on a data log yet.
It has brand new EV6 fuel injectors, The bright purple Ford racing ones. The injectors that came with the 3.0 were garbage, as I found out when it ran like crap in the first start.
I used carb cleaner to check for vacuum leaks before and after replacing the fuel injectors, and found none.
I bought a new IAT sensor, as the one I had was a little dirty, and old - No change.
The MAF seems to be reading as expected.
I plan to do these things once I have my tuning goodies in hand:
- Datalog a couple more times to get a good "Before" data set.
- Read the tune from the ECU with the quarterhorse.
- Flash the factory tune back to the ECU with the xcal3
- Read the factory tune from the ECU with the quarterhorse
- Compare the two tunes to learn what NPG did. - Take lots of notes.
- Make the adjustment to displacement.
- Write the tune to the quarterhorse
- Cross my fingers
- If the car runs, datalog
- Compare datalogs
- Rinse and repeat
Once I dig into this Binary Editor stuff, I hope I can change a couple of values to at least make it proper, as a first starting point. Does this seem like a reasonable approach to the issue, or am I hunting butterflies with a 30-06?
P.S this will be my first attempt at tuning. Now that I think about it, I hope this setup works on my car! :help:
