Hymee Pro Tuner Discussion

Great. Another question. I'm a total newb when it comes to tuning. May know how a few things work but never tuned anything in my life. How's the difficulty of learning all the basics, adjusting you own maps, etc. Have any of you started on the pro tuner? Anyone I can constantly bug for help when it comes to the pro tuner? LOL
I believe for the kit petitt use the same flashing hardware as protuner - they just don't give you the software.

the cobb access port and protuner are just different tools to do the same thing. whatever people claim the maps are the same. the discussion about the cobb access port is just as applicable to the protuner and vice versa.

All flash tuning devices/software are based on the same principles, but the available tools and how they accomplish what they do is different from one system to the other.
The available maps and DTC functions between the AP and ProTuner are different (or absent) and the tuning regimen is a bit different.
You can achieve some of the same essential functions with both, but you will go about it in an entirely different way with each.
Pettit uses something entirely different.
Last I checked, they were still using the EFI Dude stuff.

I have both acesstuner and protuner and they have exactly the same maps and values.

I'm confident hymee has the ability to work the DTC's out he just hasn't see it as a high priority. I don't need that functionality so they don't worry me either. if you do a search the access port has a few issues with DTC's, so it's not without fault in this regard.

On another matter
I've been trying to resolve an issue over the last few days .
I have my maf/injector scaling to a point where target vs actual is perfect at a particular boost level - say 9psi .
If I then run at 5psi i noitce it runs about 2% richer across the board than it should. Also notice that at part throttle acceleration it runs way richer than target maybe 7-8% .
I don't see anyway I can rectify this with the maps I have been using . Wonder if the Ve maps would affect this ?

Such is the result of using injector scaling to resolve a MAF scaling issue.
Pull some MAF in those ranges and then look at the Ve table.
Best bet is to get the idle MAF scale correct with the correct injector scaling and then work "out" from there.
Also, the closed loop fueling tables with "fix" the part throttle, <5000 RPM ranges, but they are very sensitive and prone to interaction.
On a boosted application, the IAT table needs to be completely reworked as does the BARO table.

Hmmm - have not touched any of those other maps you mentioned

How about this then - I had exactly the same issue before the injectors were scaled , when they were scaled at 1/2 way between the two settings and now that they are fully scaled .
Its only now that I have it running close to perfect under WOT that I'm looking at improving the part throttle fueling

Getting the fueling at WOT across the board means nothing about the proper calibration of either the MAF or injector scaling.
It just means you got the two related to each other enough so that the pretty little numbers in the fuel tables are equal to the output AFR.
By "100%" I assume you mean calculated load. Work in absolute.
The range you are losing it in is controlled by the CL tables.
