Most problems are install related. The only issue with the kit is the bypass actuator.
If I could do it all over again, I would. This kit is so incognito, I love it.

I finally have all my parts together to build an electric bypass actuator; I think as a first pass I'm going to grab the RPM signal going to the tach as another input to my Arduino and not let the valve move under 2k rpm.

Interesting project, keep us posted and good luck!

Did the install myself and it's been smooth sailing, even after pushing the envelope and going flex fuel. I'd definitely do it over again.

Keep in mind this thread serves as a place those with issues can reach out for help troubleshooting. Those of us who have had the kit working well for years aren't making daily posts about everything running well even though that's often the case with Edelbrock cars imo.

Still worth it to me, as long as I can decently drive it, but no OEM would ever release a car that runs like it does now. The performance improvement is huge. Most likely the issues a few of us have are related but just limited to a small number of people. If you happen to be one of those people though, it does suck a bit. I'd buy it again though.

Thanks people. Allayed my worries a bit. I'll be having a well-known professional shop doing the install and dyno-tuned by a pretty well-known tuner as well, so hopes are high that things will go well.

I am saddened that I will be leaving this wonderful community. It has been a wild ride, but how I have enjoyed it. Everyone here has been a credit to the community and has helped us all love the 86 platform and what it is.

The reason I am leaving is that I will be moving up to a Porsche Cayman S, which shares so many similarities with the 86 and is another world class driver's car.

For those in the market, look out for my posting in the classifieds. If you're looking for a 1-owner, no accident, well cared for BRZ with a Delicious tune and Edelbrock supercharger, I may have what you need.

Thank you all for your contributions and advice...it has been very much appreciated.

Found out what it was. I was watching a real time log today and saw the Delicious flex fuel content analyzer was rapidly toggling between 0-82% ethanol. During idle, the car's shuddering seemed to correlate. I then went back and looked at older logs on my computer and found an instance where a seemingly healthy sensor suddenly went dead. STFT immediately went to +35%. Measured AFR went to 19.99. All of this is consistent with the sensor reporting 0 ethanol content for E82. The ECU would think it has pure gasoline and for a commanded AFR of 14.7, the amount of "gas" (really E82) injected would be about 35% less than required to get a lambda of 1 on E82.

Solved this problem. The fuel pressure sensor that is part of the Delicious Engine Safety System that came with the flex fuel kit showed a pressure of 36-43 psi coming out of the tank. The D-box has a lower fault limit of 42 psi; below that it tells the ECU that the ethanol content is 0%. I had my shop look in the tank and they found that 1 of the clips holding the pump in the basket was disengaged. After they put it back together right, they verified the pressure was 52-56 psi as it should be.

Now the 2 remaining issues I have on my AT are:
1) While idling in gear, sometimes the engine accelerates itself and pulls up to 10 mph in first at near 2000 rpm.
2) While stopped in gear (like at a stoplight), timing is being pulled, sometimes retarded to -2.5 deg. It appears to correlate with an elevated MAP pressure (@ ~0.43 bar, ~0.27 bar while in neutral/park). Vacuum is less (~-8 psi vs ~-11 psi in neutral/park).

Anyone else having issues with gas only being pulled from one side of the gas tank? I installed a new DW 700C fuel pump (FP) for my DT FI E85 setup after the last one ate itself. I also switched to a new job with a much longer commute and noticed that the gas levels vs fill up is wrong (my previous commute was 10 minutes and I suspect I have had this problem since the beginning but I just filled up enough not to notice it). I confirmed visually last night that the FP hanger is only pulling from the drivers side of the saddle tank and the fuel level seem to only be reading from that side as well (why does this thing need two fuel level sensors if the passenger side one doesn't seem to do anything...).

I looked at a full Radium kit but I really don't want to go that far if I can avoid it. Though their web site does seem to mention a high flow FP can cause back pressure issues in the cross over so am I facing an engineering issue or a broken part problem. All the components on both sides visually look fine and there is no blockage in the hose to the FP hanger. Short of a full replacement anyone have any ideas or experienced the same problem with this setup?

Got my FR-S last month and planning to get this kit eventually. Focused on supporting mods for now. I see from OP that the kit is compatible with the JR radiator/oil cooler combo, but it doesn't mention the Skunk2 unit. That unit is much cheaper ($500 vs $900) but seems to perform very well from what I've read. I would much prefer to get the Skunk2, and I assume if the JR fits the Skunk2 would also fit since the dimensions appear to be similar. Anyone know for sure?

I am pretty sure that price does not include the oil cooler sandwhich plate lines etc.. once you add that in they are the same. Just get JR kit. Just put mine this weekend. Tested and proven. Performance is top notch.

Didn't realize that. Thank you, knowing that makes for a much easier choice.
I'd "thank" you formally, but I don't think my account can do that until I post a bit more.

PERRIN kit works well

Anyone know where I can source the RH PCV hose circled in the photo

There is a part number on that sheet for it. Just call Edelbrock to order it and give them the part number.
