I can't figure this thing out on my computer, but 002-m-p send me your email, and I will send you the vids tomorrow. I think I may have pi$$ed my computer off, lol.

Congrats on the retune. Just looking at the dyno sheet, you can see the improvement. I can see the hicup. Now you can't.

Again congrats. And I think we should have a Sharif section...

 

I took a ride in Craigs car Monday night and it is completely different than before. He scared me almost as much as the first ride, "before the crappy tune".

 

Yes, the car felt like it needed a bit of a victory lap and burnout, so We gave one he77 of a donut in a local parking lot, Sam, you still need to get a pic up of the donut.

 

We had some issues with the a/f monitor on the dyno, wouldn't work with my exhaust. A/f's are a solid 10.7-10.9 under WOT.

Ok, I think, I figured this out, the quality isn't awesome because of youtube, but here is my run. I promise to do better the next, especially since I have finally figured this whole posting videos thing out.

Was that the A/F on the left of the RPM ? got pretty dam lean on top if it was.

 

Sharif will chime in later, but the design of the rsr exhaust that I have wouldn't allow his a/f monitor to get a good reading. We tuned off the wideband a/f that I have in the car.

 

What gear was that dyno run in? It picks up really quickly.

 

4th or 5th, can't remember, pretty sure it was 4th though.

 

Obviously that car isnt registering high 14's A/F, it would have gone BOOM. Car sounds good...

 

Next time have him put the dyno wideband sensor where your sensor is on your exhaust. That is the right spot for tuning unless his was there already.

 

^^ Im sure Sharif knows how to run the dyno/tuning LOL...

 

I never said he didn't. Nor did I say he doesn't know how to tune. When you use the tail pipe your car runs richer and it's not as accurate. This wasn't directed at sharif.

 

It's late...I reply later.

 

That's awesome, lol.

 

What I was going to say, is that on most cars with extra 02 bugs, we insert our sensor directly into the exhuast stream.

However, when that is not feasible, we use the sniffer. We never tune strictly on the dyno. The dyno sniffer wideband is within .3 AF points of actual conditions. Once dyno tuned, its back on the road to fine-tuning.

This is the only way we tune cars...never strictly on the dyno.

But the poster is absolutely correct. A direct sample is also more accurate than a tailpipe reading. Overall, we've found the DD sensors, and their wideband module to be the most accurate tail-pipe reading to date.
