Making me sweat over here!
Did I send you files yet?

 

No, you sent me an e-mail (arangoa79@aol.com) wanting to know who I was I baught the AP from Narrleven. I just went for a drive, AFR was at 20 at WOT I noticed that they only jumped to 20 once I let off the gas. Example- I'm cruising at 7K in 1st gear AFR is at 13-14, once I let off the gas jumps to 20. Is this normal. Other then that the car felt great Can't wait for your maps

 

That is normal. When you are decelerating it cuts fuel.

 

Oh, and the AP said I had a 2005 CA model? I bought the car in NJ?

 

Don't make a differance.

Car was imported for use in CA. Car did not sell so they shipped it to a different state.

There was a huge surplus of new RX 8's

 

Thanks, since my AFR's are so high (14+) should I go to stock and wait for MM's maps?

 

If 14+ at 5500 + WOT I'd be very careful. But devildog is the guy who bought my unit fyi.

 

ha ha... you should see what the A/F ratio is on a stock map at WOT!

 

Well, what map are you running now?

 

Cobb stage 1, I just you an e-mail.

 

I'll make a note of that for the next time I'm piloting my RX-8 under water. "Memo to self; brakes may not work below 2000 feet." LOL

 

Jeff:

1) just sent you two emails. Disregard the 1st email, forgot to put the year of my car

2) Did ya get anything in the mail today? If not, should be there by tomorrow.

 

Got it. Files will come your way shortly.

No, not yet. But maybe tomorrow.

 

Hey, if you win Final Jeopardy one day with this info.... I want half!

 

I istalled cobb stage 1. At idle by AFR are 14.5-15.2, when I'm cruising bellow 5500 RPM AFR's are 13.9-14.7. When I floor it as I pass the 5500 RPM mark the AFR's start to drop. In 1st gear at 8K AFR was 12.5, 2nd gear 8K AFR was 12.2, 3rd gear 8K AFR was 11.2. I stayed at 8K for about 5 seconds in each gear. Don't know what those #'s mean, is it normal for AFR to drop at WOT rather then at cruise? My under 5500 RPM AFR's were high (13.8-14.9) so should uninstall the map and wait for MM's?

 

^ what you describe sounds good to me.

The lower the afr number, means less air, more fuel.

 

But my AFR's were over 14 while bellow 5500 rpm. I thought anything over 14 was bad? Or is it anything over 14K while at WOT is bad. When you guys say WOT you mean keeping it at 8K for a fw seconds then reading the # right? If it wasn't for MM and the rest of you I would probably destroy this engine

 

As a side note, how is it that MM can make custom tunes and the rest of us can't. Does he have special software from cobb that allows him too? Just curious, not that I would even dare try.

 

it's difficult to say without a datalog or a video to look at.

what your AFR should be is dependent on the load on the engine. At light throttle, you can have an AFR in the 16-17's without any problem.

While in closed loop, your car usually tries to maintain 14.7 AFR, once it goes into open loop the stock pcm setting goes pig rich.

 

You can make your own, however the Pro Tuner software costs $1,500.

 

You should read the "So You Want to Be a Tuner" thread. It will answer a lot of those questions.

 

I'll read it but no way will I try to be a tuner. I value my car By the way I e-mailed you back answers to your questions. Can't wait for my maps.

 

I am going to pray for yall. Jeff I have a free floating valium prescription if you need it.

Maps sent. Sorry about letting you slip through the cracks. You are the first "second hand" owner I've dealt with.
That thread will just explain what is going on in your engine a bit and what to expect as far as A/F ratios.

 

No problem MM, I know you are a busy man and I just appreciate your hard work. I got the maps and e-mailed you back with a few questions. I will definitely be reading that thread for my own personal knowledge.
