Well Here it is, Results from the E-Force as it ships from Edelbrock. This kit was installed as per the instructions, using their Diablo Handheld w/ their tune.
I know that there have been some concerns with their tune, This is the tuner from one of the very first kits (#10 to be exact). The tuner has not been updated either.
The tune is spot on. It does leave some power on the table, but it does exactly what it supposed to do.
I have included data that shows not only the dyno graph but the actual data log of the pull. A .csv of the pull can be had by request.
This pull was with the engine and supercharger at normal operating temps.
You will notice a few things, the first being that the a/f dips well into the 10's. This is done to help preserve the health of the engine. Obviously if this were leaned out a bit, power would take a significant spike. It could probably be leaned to the mid 11's safely. But for safety's sake Edelbrock chose to leave it a bit on the rich side.
The other thing that may be difficult to notice is that the trims in closed loop are very close to 1.0.. This is near perfect. If the MAF transfer function were off you would notice that the short term trims would be far from 1, in fact they toggle across 1 as they should. If the MAF were 15% or even 10% off it would show up in the trims while in closed loop.
Because our focus here is open loop, you can see we are netting almost exactly what we are commanding. This is obvious because we can see our short term trims (which is commanded lambda when in open loop) is equal or near equal to our netted AFR.
Overall the tune is good. Because it is rich it does leave a bit of power on the table (good for tuners) but for a canned tune I would say it performs well and as intended. It should also live a good long time.
I have logged many other s/c companies stuff. Like a 2006 Saleen S281. The Saleen tune would be considered hazardous in comparison. It would run a/f in the upper 12's and lean to 13.0 and run alot more spark then the log included here. This is mainly due to the lack of injector in the s281 cars (stock Mustang GT). They also ran similar boost levels as this log here.
With all the concerns that have been brought to my attention on both the E-force and the tune related to it, I wanted to see the results myself. I figured that I would share them with everyone who may have concerns.
I wanted to add, Peak Power was 399/379, These are obviously rwhp.
