What I'm seeing is the AFR commanded is steady, but the AFR measured will come up a hair, STFT jumps up, LTFT then climbs

AFRm drops again, STFT drops, LTFT stays put.

AFRm creeps up, STFT jumps to bring it down, and LTFT just sits at 30.

I think the AFRm is inaccurate, i just don't know why.

I can see LTFT and STFT drop way down at high RPM, thats classic vacuum leak. I just gotta find it

Well dang. I thought the EVAP would be it because of your comment about filling up then having those symptoms like how the guy said that purges the gas.

Does the Edelbrock kit come with a new PCV valve like the FA20 WRX valve?

The Harrop kit routes the PCV valve hose (all hoses) to the vacuum in front of the blower, so it never sees boost.

Any chance your PCV is seeing boost?

The Edelbrock runs a breather hose from the air filter to the front left PCV.
The right rear PCV hose routes foreward to the nose of the SC. So I dont think it's seeing boos. It also doesn't replace the PCV or upgrade it.


The plan today:
water test for leaks
vaccum test brake booster
Smoke test from brake booster through SC
Smoke test from BPV trough SC
I'm also going to run it without the K&N filter... I'm still wondering if thats screwing up the MAF

I can't wait to find the issue so I can feel stupid for missing it, but at least I'll be done.

Is the CARB tune a MAF tune or a MAP tune or both?

I recall this product. Any chance this is you?

Any chance you could do an ECUTEK datalog and post to Datazap then here?

The setup I got didn't use that harness.I'm trying to repo my laptop from my boss, once I do I'll upload the log.

I did notice my O2 is reading at 2.2, even with the engine not running. I'm wondering if it got gummed up during the initial run cycle, I had in mind it should be at 3.3, or is that elevation dependent?

Sprayed everything with water, no slurping and no idle changes.

Pulled brake booster hose, it held vacuum while running (no FT change,) and dropped but held steady after shutdown, so it should be fine.

I tried swapping the MAF harness back to the original one, made no change, but I noticed the new harness is a four pin and the original is five, maybe the wrong harness?

Damn, I'm legit considering taking it to a shop. I really hate doing that, feels like a slap in the face, but I'm stumped.

I guess what I was asking is whether your symptoms match what this product is trying to fix--not so much if you had that Delicious Tuning harness/box.

A bad o2 sensor is possible. A bad injector or poor a/f ratio condition could cause a bad o2 sensor and vice versa, which is the bitch of it.

I'm not really following you about the MAF harness.

Also, you mentioned originally that the MAF was good at 12.8 psi, but did you mean MAP, and if it is MAP, 12.8 psi seems high for that altitude. Max boost should drop at altitude.

Is this a used kit or new? You are running the stock 3.25'' pulley, right?

I'm always confused by the Edelbrock vs Harrop kits. Same TVS 1320 supercharger. The Harrop runs a 9 5mm pulley which is like 8 psi. I am running an 85 mm pulley, which is like 12.5 psi. Edelbrock states their CARB pulley is 3.25'', and it states max 9 psi, but 3.25'' is 82.55 mm, which is smaller than my 85 mm pulley, so it should be more boost, but maybe the kits generate different boost levels with the same pulleys. Yet, I thought most people are seeing 11 psi +/- on the stock pulley.

https://ww3.arb.ca.gov/msprog/afterm...o/d-215-93.pdf

Just for reference, I was hitting high duty cycles on my setup on a Delicious Tune with the stock injectors and running lean. They didn't want to raise direct injector duty cycle more than a determined max, so my ports were over-doing it. I ended up getting larger injectors. Eventually I went to E85, but the larger injectors solved that issue. Just saying.

Dude I'd never used datazap, that's on point!

Agreed

I'm not really following you about the MAF harness.
So the SC came with a new harness that extends the TB harness and MAF harness, attaches to the MAP, and plugs into the original harness. The MAF has 5 pins, the original harness has 5 wires, but the new harness only has 4. Not sure it matters.

Also, you mentioned originally that the MAF was good at 12.8 psi, but did you mean MAP, and if it is MAP, 12.8 psi seems high for that altitude. Max boost should drop at altitude.
I was refering to the barometric pressure that the MAF reads. At 4600 ft, it should read around 12.6 which it is

Is this a used kit or new? You are running the stock 3.25'' pulley, right?
Brand new kit, yeah 3.25" pulley

I'm always confused by the Edelbrock vs Harrop kits. Same TVS 1320 supercharger. The Harrop runs a 9 5mm pulley which is like 8 psi. I am running an 85 mm pulley, which is like 12.5 psi.

Yet, I thought most people are seeing 11 psi +/- on the stock pulley.
Edelbrock states that it's system pushes 9PSI, which was part of the appeal since I know the stock engine and injectors should be able to handle that.

Just for reference, I was hitting high duty cycles on my setup on a Delicious Tune with the stock injectors and running lean.

Eventually I went to E85, but the larger injectors solved that issue. Just saying.
New injectors is an expensive fix, especially for a kit that's touted as "bolt on" and designed for a stock car.

Any ideas where I should be looking?
Intake gaskets arent pulling water in
TB not sucking water, no smoke leak
BPV no smoke leak
Brake booster held vacuum and operates normally
PCV passenger side didnt suck fluid or blow smoke at valve or at the nose of the SC
Evap solenoid initially blew smoke, I reclamped the hoses and it's solid now, no change to FT after I hooked it up

I'm missing something I just don't l what

Something like this is easier to see, but I don't see anything in boost from your upload. Was this log with you just idling the car and revving it?

Is that an erratic idle?
