i don't know why but Charles using the word "jeffy" just sounds dirty.

 

It's either that or "Jeef". Maybe "Chewie's Co-Pilot" as we all know the dog is the boss.....

 

Instead of "chewies co-pilot" how about "Hand Solo".. and yes, the D is there on purpose.

 

Hey Jeff,

Any updates on the map? Am I far back in the queue?

 

I love the log.
I'll send out a file in a few hours.
I'm still getting up to speed on the new firmware.

 

Sweet, I'll download the updated AP stuff as soon as I get home too. If I have to make a new log for another map it'll be even more superawesome

 

Because after I followed the instructions, it would still drop idle rpms very low a few times and almost stall before it would come to life, and it would do this every time I get to a stoplight.

So I would reflash with the "0" file, and then redo the STFT thing. Problem is, I get a different STFT every time.



Deleted CELs, lower fan start points, etc. etc. etc.

"0".

EDIT: Then I waited for the vehicle to warm up, as the instruction says. Took it out around the block (in my case, a few rounds, because I had to go somewhere, and was calibrating as I went around campus). Stopped, looked at the STFT reading, and recorded what was about constant. Then I flashed with whatever file that added or subtracted the appropriate amount to bring the STFT to "sort of" zero. 'b' file for negative STFT values, 'a' files for positive.

I'm pretty damned sure I'm doing this right. So far I've not let one file sit for more than two drive cycles yet, since the instruction also says the method isn't valid anymore after a few.

 

MM,

did you receive my graph? I sent it to you about a week ago along with a follow up email with some concerns I had. I'm assuming it'll probably take another week or two for my calibrations to be sent to me...

Thanx,

Ramon

 

Right.....that method (STFT) isn't valid after about the first minute of running. The car will compensate for large numbers in the STFT with LTFT. Think of it like this....you start the car and your STFT is....15....and your car knows that it should be zero, so it will add 15 to you LTFT to bring the STFT down to zero. It's like the car is automatically zeroing a scale. STFT stands for "Short Term Fuel Trim" and LTFT....ahh you get it I'm sure

So......after your STFT stabilizes to zero +/- a few points, take a look at your LTFT and choose your map based on that. If it's positive, use the "A" series. If it's negative, use the "B" series

 

after reflashing any new map, the idle will be a bit wonky for a while. it settles down after youve turned the car on and off a few times, as long as you leave the same map on it.

youre changing maps way to fast dothackrave and you arent letting the idle settle down. go back and read this thread more it will help...

 

what do you mean? have the dongle plugged in when the ap is updating on the computer? im confused...

 

Just update the AP like usual with the new updater program. The AP will check the dongle's firmware version when you put it back in the car and update it if necessary. The dongle firmware update involves an ~8 second erase stage, a reboot (unplug/replug dongle from ODB port), a ~3 second write stage, and one final reboot. In short, the AP itself will flash the dongle when you reconnect it.

 

oh alright thanks for the clarification!

 

MM: Am I somewhere in the queue? =)

 

MM, you should have an email from me. for everyone's viewing pleasure (everybody loves graphs!)

AFRs in 2nd and 3rd gear:


California MT using map 2a. Hopefully there'll be a decent bump in powah and some savings in gas when it gets retuned!

 

I need to know the cruise at 4200 RPM after 30 seconds or so.

 

I'm updating my AP with the new updater software and it is hung up.

The updater is on step 23 of 23 and the AP says "updating" and they're just sitting there. It's been about 10 minutes.

Can I just unplug it or restart my computer?

I don't want to screw up anything permanently.

A Little help?

 

Nevermind. I just shut it down. Unplugged it and started over and the install went fine. Now my AP AND my dongle are up to date.

 

just updated, I'll plug it in tomorrow and see how the new firmware works.

 

it's much faster and the menu structure for switching live data is much nicer

 

Yeah, the update definitely rocks. I'll get you that cruise AFR tomorrow, I have my company truck today and my car is @ work. Yay, free gas!

BTW, I'm assuming you want the cruise AFR in 6th? Could you possibly make it use a bit less gas from 65 mph and up while cruising? I think 4200 is a bit higher than it's usually sitting at while on the highway, but I don't remember. There are way too many cops in NJ to really speed for long distances. W/e, I'll give you both cruise AFRs.

 

Got something for me soon then?

The new firmware from AP seemed nice. Looking forward to checking it out with a new map

 

updated firmware... question... anyone have the cobb 2.0 driver they could email me?

 

did the update last night, MUCH faster live data!!

Ugh, hit 11.1 AFR a few times this morning, time to datalog and send to Jeff.

 

For some of the new users, it would be nice if this quick start guide was corrected. Find the errors.
