Hahn Turbo – Installation, support and general comments

SaltyClownNY Did you have to cut a bit of material from the hood to get hood to close over the Hahn Air Intake.
no. I do believe that there was one other that had that problem, but they realized that the trey was mounted incorrectly. They may want to check that.

After selling my NA Hahn CAI, I tried to install my turbo airbox from memory and inadvertently mounted it too high. When I went to shut my hood, I pressed down to check the hood latches and starred my hood! I wasn't a happy camper when I realized what I had done. Properly installed the airbox shouldn't hit the hood. I replaced the stiffer rubber molding Hahn supplied with some 1.25" x 1.25" foam insulation normally used for sealing around window AC units. I prefer the softer foam as I believe it seals more easily to the hood w/o any undue pressure on the hood.

Now the question is, are they making any adjustments and if so, to the piggyback? Are you in stage 2x for that? I would think not. I believe Bill claimed 250 HP at the wheel. DDM was saying they were getting on average 12.5 HP for each PSI of boost. Bills was pushing peak of 8 for the stage 1, so that "should" give you between 80-100 HP added to the machine. I believe stock is 176... I think... So it should be a peak of 256-276HP at the wheel. My take is that Bill may have been on the "safe" side and probably didn't put that much time into the tune... don't know that, but a hunch. If you put stage 2, it will push it to just under 10, so should add another 20-25HP. I was hoping that someone could verify Bills tune.
I can't see the entire graph, but looks like the stock is coming in at just under 150HP at the wheel? Is that the case? If that is true, then the system is pushing an added 90HP, so 11.25/PSI. Almost what DDM was claiming. This is all assuming you are at stage 1 though.
Thanks for the info!
Which AEM FIC tune file was used for the posted Dyno graph?
There was the original tune and a modified tune file that I pushed Bill hard to get done. -
Codes 3 and 4 for 106 are usually just junk codes. They usually happen when riding at elevation above 5-6k feet.
If AFRs are good, I wouldn't worry much about either code.
Remember with 5 repetitive starts and stops of the machine with the ECM not seeing the "issue", it will clear the check engine light from the dash. This trick helps in diagnosing these odd issues.

Imagine how it's going to feel when it's on dry road and no snow or ice in your area

Turbo is installed and working. However on occasion when starting it takes up to three times to start the motor. Shop can't figure it out. They disconnected the turbo and the motor fires up on the first attempt each time. They reconnect the turbo and sometimes it can take three start attempts to get it running. Once running the turbo operates as expected. So a bit of a mystery.
Sounds like time to contact Bill Hahn.

Had a similar issue with mine - not the same set up as yours but we had to add a little more fuel at start up in the tune.

I figured my response was rather obvious, but I was concerned about how quickly Bill might respond given the comments aimed his direction recently. He's always been responsive to me and I hope you get this problem figured out. Good Luck.

On a rather extend push on the peddle yesterday i got this error code.

I think that is the Knock Sensor Code

From the service manual., 65565 - Oxygen Fuel Sensor Trim A - The fuel trim is either above or below normal. I would probably reach back out to whomever did the tuning and give them a detailed account of what you were doing at the time.

The code 65565 is for Oxygen sensor fuel trim "A" like Kyle D said. The thing to look for though is the modifier that is under the code "1" which specifies the code a little more to mean - Fuel Trim below normal and also relates to a a P1171 code, which is "Fuel System Lean During Acceleration" and correlates to the description you gave.
There could be a couple possibilities, first thing I would recommend checking is the gasket between the exhaust side of the turbo and the downpipe on the HAHN kit. If there is an air leak there, you will get an artificial lean code since the air enters at the leak and makes the ECM think that the engine is running leaner than it actually is. It's free and quick to check, do you remember putting the gasket in during the install?
I do not remember, but are you using Bob's tune or the piggyback from HAHN? If I remember you are using the piggyback from HAHN and definitely would be another thing to have checked if it is the HAHN tune, the Bob tune for the HAHN kits was pretty mature and stable.
Hope that helps,
Dave

I get the O2 off as well, but ONLY when I'm driving for long periods and the RPS's are consistently the same. Once I start giving it gas and moving, it's fine. Odd thing is, The AFR says all is good. I'll have to check for any leaks, but shouldn't be an issue. Other than that, I haven't had an issue with the machine. Still love the Turbo and glad I went the rout I did. Looking forward to seeing all down at Maggie this year again!
