Interior looks great int he before pics. I can't wait to see the finished product. FWIW, I'd upgrade the QR to a Rothsport. Big improvement over the two-pin QR you have right now, and will save you precious time should you ever need to get out in a hurry.

I was waiting for you chime in but i admit I didn't see the Freudian take on the shifter coming. But I thought it is common knowledge that all Porsche owners are compensating
So how you are getting fuel data- are you using the BMW adapter?

And I'll look at the Rothsport again- I think it was going to move the wheel too close as I recall.

I may be wrong, but from the look of the hub adaptor you have on there right now, I think the Rothsport may move the wheel further away from you.

PS: Dan gutted the wiring harnesses and dashes in 2 more 996 race cars. I'll take some pics this weekend as we're racing at Cal Speedway.....

The guy we bot the AIM from said that if we give him the tank empty/full resistance values he can get us something that'll work. If not I'll call Dan. And still waiting for Turner to get back to me about the BMW adapter.
One thing we would like to eliminate is the whole key and steering lock mechanism which is literally postal tied up under the dash with the key in it for the DME to see. If anyone has experience in getting rid of this and tricking the ECU into still seeing it I'd appreciate hearing about more.

I bypassed the factory gauge and wired the factory fuel sender directly into my AIM data acquisition dash, using this adaptor: http://store.bimmerworld.com/fuel-le...tor-p1689.aspx
I calibrated the first 10 gallons one gallon at a time and then used larger increments for the next 10 gallons. Knowing the empty and full values is not good enough as the reading is not linear.
You simply put the AIM into live data acquisition mode and record the volt reading as you add each gallon. Then create a table in the custom sensor section. It is really quite easy. The dash now reports in 'Gallons remaining' instead of as a percentage left.
Note: I did this in my Ferrari, not 996, but it should be exactly the same.

SO WAIT.. in the pictures it shows a Racepack IQ3. are you changing over to an AIM?
If So, you already know the info below so no reason to read the rest. Sorry I came late to the party.
If not, and it will indeed be the Racpak IQ3, there aren't any inputs to connect the IQ3. (BMW FUEL OHM READER) He has to buy this Racepak IQ3 specific part... USM.. CLICK HERE Then he can calibrate the USM to do the same that you guys have to do for the AIM that seems to have a direct feed to the screen, (which the IQ3 doesn't have.) The USM, (Universal Sensor Module) is $180 and allows you to hook up 3 more inputs like oil temp and what not. - 4 inputs total. He won't have to buy that $80 piece from the Bimmer link.
All other inputs to my personal IQ3 will be from the OBDII link Racepak offers. Very little wiring for a lot of information. RPMS will be wired directly to the dash as it's the only one input the dash allows.
Here is a copy and paste on how to calibrate the IQ3 USM for fuel.. Much like that other gizmo link;
"So what I did is used the 90-0 ohms fuel level sensor calibration table already provided with the USM from the pull down menu. It's not going to be 100% accurate but I never run my car that low of fuel anyhow so it give me a little buffer. It sound like the NSX you can use the same table as well and be really close to the factory needle gauge. I've only taken the car out once since doing the IQ3 upgrade but I noticed it was reading way too fast and kept setting off the warning light on turns. I need to lower the sample rate next time out.
The better way to do it, which most people on here do, is empty the tank and then manually calibrate it by taking readings with a marked fuel container. You know like add a gallon at a time or so until full. That way you can actually have a gallons to empty reading rather than a percentage.
The wiring, I just tapped into the single wire from the fuel sender and put that into "signal" for the USM."

^^ Yes- switched to AIM.
Has no one deleted the ignition key/steering lock mechanism- it must weigh at least 5 lbs, and must go!

Thanks. Do you mean they reprogrammed the DME? Did you send them yours and they sent up back modified?
