You want your low-RPM torque back? You'll need a better cam than the E303 for starters. But all is not lost. Your engine is forced induction which means regardless of the E303's shortcomings on the bottom-end, you still will have more than most running the E303 will. Also unless you are already adva...

Also keep in mind, don't treat your tools like they are your brain. Your tools give you eyes and ears into aspects of ECM tuning that you couldn't access before. That being said, you shouldn't blindly copy/paste everything EA suggests over to the BIN without running it through your own thought proce...

That sounds like what was holding you back. Also keep in mind when datalogging KAMs/LTFTs, you don't really read the memory of the EEC to get the table of values. You kind of "catch" them as you pass by certain RPM/loads. Thus, if you never hit 3000RPM at 50% load, then when you map your datalog in ...

To me, limp mode & tip-in are two different things. Tip-in being positive accelerator movement. Where limp mode indicates things are not right...ie a check-engine light is on because a sensor is malfunctioning.

To label the tip-in spark table LIMP is misleading IMO.

You can do quite a bit without a WB, but from what I can tell, the only thing the WB is required for is tuning in fuel tables based on WOTs and OL acceleration. EA will take care of the midrange by getting you whatever fuel economy you can get and drivability in the idle-to-moderate acceleration ran...

I found that in the colder months with my ACT sensor in my air filter, that I had to lower my ACT Minimum Adaptive scalar from the default of 100° to something like 40° so that the KAMs would start adjusting.

TunerPro exposes more of the tunable parameters than CalEdit does. In fact, ever since I started using TunerPro, I NEVER use CalEdit for doing anything but downloading my BINs to the TwEECer. I also find that TunerPro is more accurate than CalEdit. For instance, in the A9L tune, Mike's screwed up th...

No, you never want to go from CalEdit backwards. Start with a known good BIN like the A9L or X3Z BIN and then modify it to your taste. Save it, then load it in CalEdit to download (send to) into the TwEECer. Even though you can upload setting in the TwEECer, there's really no need to ever do this. I...

I don't know what TunerPro would be doing to the BIN to make it run better. However a more likely reason it's running better is when you started over with a base tune, then modified the things that HAD to be done and ended up with a better setup than you'd evolved your CalEdit tune to to be.

The HEGOs are one of the major pieces that makes injection superior to carburation. If you take that away, you might as well plop a Holly on the top of the engine. You'll likely get just as much control out of it and probably more power...as compared to an ECM running in limp mode. Now again, if you...

Even with a TwEECer, there's nearly no difference between A9P and A9M. They are the same strategy.

It's funny that you mention the one more meaningful point on the curve when the defaults almost always have a few entries filled with 0 volts where they aren't using the whole resolution afforded to them as it is.

So why do the MAF curves always have "16" at the top of the curve and it's usually the same exact flow value as the number just under it, usually 5 or 4.99?
