Hymee Pro Tuner Discussion
I'm not trying to argue with you, I was trying to give a reasoned response to another question.
Since there is a sensor there that the PCM can read, and we can alter various behavious based on the sensor reading, then it can be utilised... Good bad or otherwise.
Cheers,
Hymee.

Since I know the table structures and definitions, it is plausible to increase the resolution and add in extra rows/columns. A bit of byte shuffling etc, but possible.
The range might be enough, the PCM interpolates intermediate values anyway.

I've been running Pro Tuner for a while now so thought it was time to talk about my experiences with it . I'll start with a little background on it
What can it do :
*Flash tuning of the factory computer with access to all engine controls
some examples : fan switching control , intake valve control , maf calibration , injector scaling , fuel mapping , timing mapping etc etc . Pretty much everything the AP can do .
*Logging of critical tuning information . Up to 2hrs worth i understand (not 100% sure on this) This is done via the plug in 'brick' .
*Real time display of all engine parameters monitored by he ECU - ie Scanalyser via usb port
*Normal Scanalyser software also included in the package
Some observations :
The first thing I found when attempting to tune my turbo 8 was that you cannot tune in real time . You need to take logs then load those logs onto your computer and analyse them then make the necessary changes .
I was used to my Powermod piggyback which can be tuned in real time so I initially saw this as a drawback as I could not imagine that you would want to dick around like this while on the dyno trying to tune .
Now that i've gotten used to it I really like that it works this way . You get to study the logs and make changes in a orderly fashion . So if you are a diy kind of person this way of doing it will suit you . If you are going to hand your tuning over to someone else that you are paying an hourly rate to , then this is not the best in my opinion.
All the critical maps that you need access to are available to play with at your hearts content but you had better get an understanding of what you are doing or you could easily get into trouble .
Hymee provided me with a base map that he uses for his supercharged 8 . I found this worked very well with my turbo . I only had to fine tune to get an excellent result that I am very happy with . I have now have very stable afrs throughout the rev range .
As far as funcionality is concerned - Hymee guided me through the learning phase pretty well and was always there if i got stuck . Top marks to Mark for service .
The software works very well as long as you follow the instructions - if I can figure it out anyone can .....

And I've been runing the Pro-Tuner for about a year, and this has totally open up the Rx8's Computer for re-flashing, Easy to use, does the job fast, I've done a re-flash on the side of the road.
Base maps form Mark were very close to what was needed, this is by far the Best Money I've Spent on My 8.
But Unlike Brettus, I don't use the Pro-Tuner for logging or live, I've got XP, and have scanalzyer V2, which I'm more than happy with using as a logger or with the live mode.
The Pro-Tuner is that a Tuner tool, one of the Best.
Cheers Mark.

Yes.
First of all, the old mantra:
FLOW is not PRESSURE.
"1 BAR" might mean a wide range of things.
That said, I exceed 1 bar pretty regularly with the factory MAF and my calibrations.
What I am talking about here is NOT a MAF replacement.
Rather, it is a supplement to the MAF in deciding how to handle the movement of positive air displacement above N/A.

But fair enough, so how much flow - grams per second, CFM, lbs min, whatever, are you seeing across the MAF on your application? Have you seen a limit to flow that it can handle in conjunction with the limitations of the PCM?
On a "draw through" setup, this makes no difference.
On a "push through" setup, it shouldn't make any difference (hot-wire MAF is not subject to pressure variations), as the MAF is measuring the mass flow, based on the cooling effect of the air molecules on the hot-wire. I'm doing some of my own research on the applicability of having a pressurised MAF, but there are OEM and aftermarket setups out there that have the MAF on the boost side. In the end, it (mass flow) is a measurment used to determine load. And these PCM's use load based tuning.

Hymee.

If no one has reached the limits yet, or pushed that far, great. I'm just curious having to this point only used MAP based systems. I'd like to make the switch to MAF but as of yet have not bothered.
A topic that has been beaten to death with no need of re-hedging when it is understood and accepted.

I guess my question would be the same...what are the limits of actual volume flowed through the factory MAF/tube/PCM load tables before you lose granularity...or has this not yet been determined?

IAT showed 65°.
The MAF is good out to 425 g/sec in the OE tube diameter.
So, yes, I will run out of MAF soon.
I'm actually running out of PCM resolution even faster.
I've exceeded AbsLOAD of 2.00 and That is where I setup my limit!
I'm starting to see AbsLOADs around 2.05

Scaling the MAF. I know it was asked here.

hymee: is it possible to scale the AFR gauge on the software for a turbo application? (otherwise it's going to read super rich at all times)
CarPC is in my very near future and this will be wired into it at all times.

let me clairfy:
When I'm running the Live Mode, the AFR gauge can be set to have a "rich" and "lean" zone. I want an accurate reading, but the sweet spot on a FI car is richer then that of an N/A. I want to scale the zones. (get it?)
Car will have an actual AFR gauge, the carPC is just for fun as it'll monitor other aspects of the vehicle.
