Hymee has a noticeboard for just such things .
My 8 is fully tuned on Protuner running a turbo . Happy to help .
Good idea to start off by tuning an NA car IMO .

yes that's my plan, just trying to learn about it as much as possible before I commit to buy. Not so much info on the pro tuner as there is on other ems's

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.

I believe for the kit petitt use the same flashing hardware as protuner - they just don't give you the software.

No and no.

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.

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

What are you talking about? The Hymee ProTuner stuff doesn't even mask DTCs. How is that the same?

your not talking about tuning differences you are talking about minor functionality. they use the same engine managment and they are just different ways to tune the same maps. each give you slightly different focus. however they are tuned the same way.

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.

I loves me an apologist.

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 ?

Temp Maybe?

Corrections for IAT may be dumping more fuel as the lower charge air is cooler...

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.

This problem is with the injectors correctly scaled BTW (not the way I had it last week).
Hmmm - have not touched any of those other maps you mentioned

How do you know the injectors are properly scaled?

If they weren't I would not be able to get target vs actual lambda to match up ....

Not true.
The MAF calibration would mask this and then the injector staging comes into play.

Well when I scaled the injectors the change in lambda i had to make , exactly matched the % change in overall fueling . That is to say the changes to the fueling were as predicted .

Well, obviously not if it is over-fueling at lower loads.
You just matched the end-points.

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

Well, then since you've decided you have it right, adjust the things you can.
MAF scaling at 40g/sec to 100 g/sec and CL fueling A and B.

Brettus - have you tried the MAF tool in my software? It may help you find these kind of "holes".

It's more than a "hole" .
With all the playing around i've done with the maf and noting the effects - I can't see it being maf related .

Its worst at low rpm and over 100% load BTW - 3000-5000 rpm

Use the % to add or remove map in my software..... at least that will mark the cells where your jacked up.

I haven't looked at your software -sorry . Mainly because i thought i had it pretty right before you got it finished.
But I have done charts of actual vs target and they are damn near perfect at wot and 9-10 psi from 2000-8500

PM-ing.

Remember - my software takes in a LOT of data - not just WOT BS; so it will find areas in your map that are off.

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.
