Hi Ed I have never met you but you have been recommended to me by every Rat Pack member I have met and I would like to take advantage of this Q & A.
I have a 97 A4 for a year and a half I have always wondered if it has some tuning done to it because of the way it shifts (hits fairly hard) I have never been in any other C5 so I really have nothing to compare it to. After checking the rear end I found out that the original 2.73 were changed to 3.42 out of a Z found this out by the tag on it. I read a post one time that stated that if the gears were changed it had to be tuned to shift correct with the new gears is this true? if so then I'm sure it has been tuned and I ques the torque management has been removed or reduced? if the torque management has been changed is it a permanent or can it be put back to the default? is their anyway to find out what has been changed without going through the motions of a real tune? if not maybe one day I'll bring it to you to have it dyno & tuned and you can tell me what I have. I'm really not looking to change anything right now I'm still trying to figure out everything that has been done to it before it was mine. I feel like I should figure out what I have before I start changing anything. Thanks for any info, Kevin

Only way to know what's been done is to pull the tune and do a compare. You can always put it back to stock. TM or whatever. It can always be un-done |

Adding a wet N20 system, with Microedge controller, to my C5. Vortex Rammer, Pacesetter shorty headers, Borla catback for mods. The only things changed when I had it tuned were the shift points, the TM reduced, and the fan on/off temps changed.
Won't be tracking the car. Adding the N20 for the fun factor and to get up to speed quicker when we have our MESV cruises. Since I don't run a wideband, should I have it tuned after the install and pull a couple degrees of timing to be safe? Or, am I going to be OK with that small of a shot of juice and leave things alone?

If you're only going to spray it with say 75 hp, you probably don't have to do a thing. If you wanna hit it with 100+, then you need to tune for it. |

I plan on coming down with Kevin when he picks up his "cruiser" from the 427 build. Can't wait to see the shop.

If you take out timing for the nitrous hit won't that affect performance when you're not spraying? How does that work exactly?

I know the Microedge controller has an interface that works this way.

The newer electronic ones are cool. Kyle (stonabones) runs one. Very, very tunable. Comes in handy trying to get a C5 down the track on a 250 shot without leaving a trail of broken goodies!! |

Hey Ed,
I was doing a little spirited driving the other day, about 30 degrees outside. I threw a P1011 code, which is for the MAF. I haven't troubleshot it yet, but I plan on checking the wires, cleaning the MAF sensor then start logging my next spirited cruise. Do you know of any other issues that could throw off the MAF sensor? Do you know of anyone with a C6 putting in a honeycomb before the MAF to straighten/smooth out the air flow? Do you think this is worth looking into or would I be better getting this tuned out?

Don't be surprised if I screw up my tune so bad I need to have it towed to you for a fix.

Ed will probably get 700HP out of it. Give him a shout Monday.

Is that going to be one big shot, or two stages?

When you tune a car that doesn't already have a wideband do you just stick a sensor up the tailpipe or do you replace one of the existing O2 sensors while you tune?
Also, I want to install a wideband on my coupe but am a little confused on where to mount it. Some people say in the X pipe which sounds good to me but the manufacturer and a lot of other people say it needs to go before the cat (I have LG hi-flo cats). If I put it before the cat I worry that it will only be reading one bank. What should I do? I'm putting the wideband in because I am adding a nitrous kit to the car if that matters. Thanks
