Edelbrock E-Force Troubleshooting Manual

[wsfrazier]

I don’t have the stage 1 but I’d like to share my experiences with the part throttle issue. Beefcake tuner kit with stage 2 intake/ e85 only. Tuned by rob at pbd

when I had 3.55s it had a lot more part throttle issues. It felt like it didn’t know what I wanted. Gear changes and high boost with throttle input past light acceleration but less then the amount you’d use to accelerate hard (3/4 throttle)

3.15s def fixed a huge majority of the issues. I used a nitrous pill and it helps a little as well.

IMO I think the tune isnt the problem. this TVS and the 10r80 make for a lot of snappy power and many gear changes. I think it’s just how it’s going to be, honestly

I disagree, try a different tuner other than PBD, such as Lund with these blowers. You'll see the difference.

I’m in the middle of doing a Lund tune with an EB Stage 2 with A10 and 3.55 gears. I’ll report back results soon, but even the base tune file feels pretty smooth, but I have very limited drive time on it.

Sounds great

You could be right. It’s crossed my mind early on. I was told that my specific build date had some differences in the tune (Was told third hand by the shop/ dyno owner)and he couldn’t use the base file as it was shifting funky and had to build a new base file. Don’t know how accurate or how many other cars it was affecting before. If it wasn’t on a dyno with a guy he knew personally, he probably wouldn’t have known

I thought the stage one came with a 3.5" pulley. Did you guys get a different size with a tuner kit or are you stage 2?

My Tuner Kit gave me the option of pulley size. 3.25” was the smallest recommended by Edelbrock.

Stage 1 2650 comes with a 3.25” and makes 10.5-11psi. I replaced it with a 3.5” to make 9ish psi.

I think that I've finally got my tune sorted out by PBD. 12th revision seems to have nailed it. The weather is too bad today to try everything, but all part throttle positions at low and medium speeds are almost as smooth as when the car was new. No more bucking/jerking/surging. Idle is on the fast side, but it's smooth without any more up and down oscillations. I also haven't noticed any surging uphill in cruise control.

My car is an early production '18 made in November of 2017. I recall reading somewhere that there were some production line changes with respect to transmission programming and some transmission hardware during December of '17. I know that Ford issued an SSM for the 10r80 front assembly of cars made prior to January '18 and mine was one of them. My dealer replaced the entire front assembly and reprogrammed the tranny. This may have been causing some problems, because my base file was saved, before any of this work was done. Anyway, I'm guessing Rob might have rebuilt the base file to account for these changes.

Damn, is this car ever fun to drive now...

Good to see you got it sorted out. Why it takes PBD so much longer than Lund is beyond me but in my experience, it was worth it.
Interesting that boost sits around 10.5-11 psi with OR LT’s on the 3.25”
I’m about to start working with PBD on an E30 tune for mine. After some back and forth it was decided that e85 pushed the fuel system far too hard.
I’ll share the results here in case anyone wants to consider doing similar.

Does anyone else have issues with the RPMs raising and dropping while at idle? Other than the post above
My car bounces from 500-700. I’ve checked all connections to the MAF sensors, air filter connection.
Also wondering what folks with stage 1 are seeing for AFR @ idle. My car rests at 14 according to the dash.

Yeah, mine has long tubes, no cats and no resonator with whatever the standard pulley size is for '18 and above Stage-1 kit. My boost peaks at 8.7lbs. I think with stock exhaust, my kit is supposed to be around 10lbs.

I, for one, would be interested in what your results are with the E30...

My fast idle used to oscillate like that, but only by 50rpm or so. It also used to surge the same way going uphill in cruise control. Both issues were fixed in my latest tune update. My AFR was around 14 at fast idle, but it would oscillate by half a point or so in sync with the rpm.

I had my car vacuum checked with a smoke generator and had my MAF, O2's and injectors checked just to rule out any hardware problems. It was all in the tune...

The only time I had a hunting idle with the EB tune was when the air filter fell off the MAF housing.

When you say the AFR rests at 14, do you mean it literally sits at 14.0 for a few seconds before venturing maybe 0.1 either side of that? Or is it more lively than that?

It moves slightly, depending on what the RPMs
are doing. I uploaded the Datalog here as well as sent them to Edelbrock last week, along with the .bef files last night. Hopefully we can get it figured out. The car should run way better than it does.

looks like a vacuum leak but I have no idea of where.
