Calling at 8:30pm PST. OK?

 

Looks good but for us noobs what do you guestimate that will translate to in terms of bhp/whp?

 

Yeah, I'm up to date and stoked about the logging. I'd pretty much given up on getting custom tunes as I wasn't sure about how accurate I could draw the numbers with one hand while driving with the other.

 

The passenger is supposed to do the hand job.

 

Pun intended?

 

always! just my opinion, i could be wrong.

beers

 

Just jumping back into this, is the new base-map available?

 

i couldnt find the cobb ap turbo thread so im posting in this one, i finally got my turbo kit install complete and had previous maps tuned by jeff a few months ago stored in my ap, do i need to start from 0 or can i go straight to the calibration jeff made for my car? (btw this is the second time having the turbo kit on, rite now im on the factory settings without any ap maps, just want to see whats best before i start the car and drive it)

 

^go for it, if it's jacked up, then just wait for Jeff to send everyone new base calibrations

 

Alright, so! Just got my Cobb AP yesterday, did the flashing this morning. CEL gone from missing cat, car idling smoothly, nice! All is well!

So, I went to do my STFT drive around town, and when I came back, I was sitting with -12/22 on my log. Now, at almost all RPM, my numbers were between -4 to -8, says my passenger. The only time it hit positive numbers was during lift-off of the pedal.

So, I guess I might be a bit confused with the instructions here: At this point, should I flash on the -4% map? Or what


Thanks!

 

Here's a 2nd to 4th gear run I made today if anyone wants to take a look.

This is with:

- NA form
- TurboXS headerback

 

Did Jeff send you the new calibrations already?

 

no, i'm still using the old stuff. How's the logs look?

 

I won't be "sending" anything.
I'm going to post all 20 of the new "base" calibrations that go with the new start-up process.
The whole point is to try to make it as fool-proof as possible (yes, I know about them making a better fool...).
There will be a new thread dedicated to the process as well.

I'm in Bisbee at the moment, working with just my eeePC, so it a little bit slow for me to do any work, but I am assembling the page as I type this.

 

We love you Jeff.

 

sweet.

 

That makes alot more sense. Thanks Jeff!

 

Have a local tuner that is going to give a shot at tuning my car. Just wanted to know if the racetune software is everything he needs to get the job done. Thanks

 

This has been something I've been putting some thought into. The only problem is we would need to do one of two things. Either we would need multiple vehicles with the same MAF calibration or one single vehicle that we swap intakes from.

The end result wouldn't be how much airflow each intake allows but whether or not there's a variation from the stock intake. It would be interesting to see.

Crap! Does this mean I'll be needing to make a few more passes down Pecos?? DARN!

 

Yes but not all cars are the same even though they have the same mods.

My fuel injectors don't flow as much fuel as they should so Jeff had to make me a very very rich map in order to get it right.

 

That's why we would probably need to use the same car as a control. Still, the primary issue is since we would be using the MAF to measure the airflow. This would be fine if all intakes had the same diameter tubing but they vary in size.

As such, the MAF's readings could be off. You could have a situation where in reality the intake flows the same air but the MAF shows an increase/decrease in airflow. It would scew our results.

We would need some kind of accuracy since if we saw a 10% increase in airflow it would be amazing.

I'm sure there's a way to do it but it's escaping me at the moment. I'm curious what Charles or Jeff has in mind.

 

Hey, what can I say, "talk to the hand!"

 

If you use the same car - get fuel information (plug in an EMU with no tune on it) and my software will already do what you want.

 

^^He's trying to accumulate air flow changes from various aftermarket intakes vs. stock, not calibrate the MAF air/voltage table.

Personally along with the MAF reading I think it would be wise to log STFT, LTFT, and AFR for a little validation on the accuracy of the MAF reading.

 

IMO - I think you would want MAF Voltage STFT, LTFT, AFR, ODBII Airflow g/sec, and Actual airflow g/sec.

But that means you would need an EMU and or figure out how to get useful fueling off the ODBII; apparently not doable yet.
