Whats crazy is all three tps sensors are new. He had a big thread on this in the paat. Throttle body, throttle motor and pedal sensors were all changed 6 months before he started trying to sell his car.

Funky was probably full of ****...knew what the problem was just said he fixed it rather than spend the money.

The car came with two sensors so I think he was trying to fix the same problem. The thing I noticed was the TPS sensors that were in the car had different numbers and the BMW serial numbers and emblem etched off. So not sure if they were bought used or not. This could not have been solved unless the AEM was tweaked to filter out the signal noise which was messing aground with fuel map throttle percent and rpm map. The signal would make the map jump all over causing low and inconsistent afr particularly below 25% throttle. The AEM map is setup with a very high throttle resolution below 25% so any fluctuation in signal voltage effects the fuel map. I wish he had been up front like have said before I would have worked with him with that knowledge.

Found source of noisy ground messing with the TPS voltage signal. Just unplugged the alternator and the voltage noise reduced dramatically with the engine running. So I'll be replacing that very soon which should solve the noise problem. If in case that doesn't work then ill trace back the wiring and try and isolate any noise from the TPS wiring. Currently the TPS is running along side the injectors so I could isolate them which should reduce the noise from the injector pulse. Then Ill tune the AEM to compensate accordingly. This is kind of fun

After tuning Driving this car is amazing. I hit 17psi boost at 45% throttle at 3400 rpm on pump gas. AFR across the board are excellent within a few percent of ideal. Very smooth acceleration and power. Looking forward to doing a 94 tune and seeing what power I can get. Ill be remapping the 110 octane map to 94 which is more usable for me. Then I can just switch between fuels depending on my mode at the pump. Ill tune it for 1/8 91 octane and 7/8 94 so that I don't have to drain the tank when switching fuels. I'm also going to add an extra fuel transfer pump in the tank so I don't have fuel starvation in right hand turns.

Nice! The fuel map switch just changes timing anyhow...everything else stays the same...relatively iirc.

I'm thinking I can increase by 2 degrees of timing over the 91 fuel with 94. Ill have to tune it on the dyno with monitoring the knock the sensors and see the power difference.

I'm sure you could increase your base map a bit too since you'll be monitoring everything...remember the kit was tuned very conservative but since you're off warranty...let your conscience be your guide

Ditto, HPF was a great help when I purchased my used 2003 2.5 m3 and had it shipped to Kansas. It was in the shop for 10 months trying to trouble shoot a horrible rich mode at idle. They tested everything we sent back to them and in the end it was the Vanos that neded to be replaced. Car has been running great ever since and they are always available to help.

And unfortunately this random rich mode that progressively got worse was not disclosed to me by the owner. To their defense it was not claimed to be a daily driver...only 35,xxx miles.

Unfortunately it'll be tough for HPF to keep the same level of help with only one tech now...and no tuner.

Sounds like grounds for a big raise!

Couldn't have done without his help. He is passionate about his work

Was able to get the AEM to log my Alternator voltage along with my TPS signal voltage and noticed they coincided in fluctuation. The alternator voltage was between 11.7 and 13.3 volts running indicating a problem. Should be 14+ volts charging! So it will be good to have that replaced this week.

ECS had a good deal on a rebuilt bosh unit. 202 plus 75 core charge. So I went for that. Will be here Thursday.
