View Full Version : AP tuning versus Int-X tuning?

Okay, so If i'm understanding correctly, the Int-x can be tuned in real-time, somewhat similar to the AEM EMS ( that i had on my supra ). But the AP cant?

So with the AP, you have to run the car, while datalogging, and then finetune the map, upload the newly changed map to the AP, then install it into the car?

is that correct? that just doesn't seem very cost effective in terms of tuning in the long run =/

far as i know, you can tune in real time on AP.

int-x is not granular enough to replicate OEM-like tuning the AP can do.

I had no idea you could tune in real-time, I havn't seen many posts talking about it, other then just sending raw data back to the guys who made it for a better finely tuned map lol.

the other issue ive seen is the AP has trouble with the maf/blowthrough/bov to atmosphere problem? this was the main reason i switched to the AEM EMS on my supra back in the day, is there work arounds to this yet? as i plan to be FI by the end of this summer...

it may have changed since the last time i saw it mentioned, but last i saw you cant tune in real time with the AP... it still has to be flashed like always.

BUT... the AP is leaps and bounds beyond the Int-X either way..

because until recently, the only one who could tune the ap is someone with the professional version of the software, which costs several thousand dollars. So Jeff made maps and shipped them out.

Now there is a street tuner software, it's free, anyone can use it, but if you're venturing outside of NA use, you better know what you're doing :)

You should be able to make changes in real time on your maps loaded in the pcm's memory without saving the changes, yet the changes take effect immediately.

vent to atmosphere is problematic with MAF setup unless you have a blow through setup where the venting happens before the air is measured. You can get away with it even without blow through, but you'll have "popping" exhaust from it being too rich during shifting.

I can't deal with that on a DD, so I recirculated.

yeah, which is what I am trying to avoid too, it's just a shame to have to recirculate. I guess on the bright side though, I can just go ahead and buy the AP now without worry. Thanks for the help guys! if you have more to add, feel free!

"real-time" maps are not supported on the mazda AP software... only the subaru software

No real time tuning with the AP. Datalog, tune, reflash.

OMG ok so you can? or you cant real tuen?

"AP has trouble with the maf/blowthrough/bov to atmosphere problem?"
Is this only for people that are FI?

The only cars the we can real-time tune at the moment with our software is Subaru's and Evo's. But we're always working on others.

Can use the AP to tune, just not in real-time ( as your dyno testing ).

And correct, that is an issue for FI people.
