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

Logging...
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.

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)

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!

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.

You know what - that would be an EXCELLENT experiment.
No, I don't have any MAF data on that.
But now I want to get some!
I guess I'll put out a feeler to AP customers that don't have an aftermarket intake and see what their flows look like and then get new data when one puts on an intake.
We could probably do the work ourselves with Flashwing, Easy or on your car if we find ourselves with an afternoon and nothing else to do.![Uhh](https://www.rx8club.com/images/smilies/uhh.gif)

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.

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.

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.

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.

Find a completely stock RX-8 and start swapping intakes while gathering MAF sensor data with each swap. Same as dyno testing except we are seeking different data and the process doesn't cost any money.
As for the application of my own, ported, engine we can also make comparisons and evaluate the upper limits of the factory intake box. Not only MAF sensor data, but we could also hook up a vacuum gauge somewhere between the factory air filter and throttle body.

^^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.
