stock maf is a meter preset from factory. right. i dont think ford would be like thats "close enough it doesnt have to read perfect." it tells the ecc its got so much flow going tru it so how can you go back and tell it no its really flowing this much with out being able to actually measure it. just because your wideband is showing you need more fuel at such rpm? like i said i just staring tuning so i could be misunderstanding some of the stuff i read. does not apply for aftermarket meters.

the program they download into it would be a general one that would be good in most climates/areas. But I can believe that throwing it on the dyno where it reads real world data which can vary from place to place would show differences depending on the climate that it is in. Two identical mustangs ran on identical dynos on the same day at lake taho and one in phoenix would show different readings because of the change in climate, temp, air pressure, ect. Tuning the maf for the climate that it will run in would maximize its settings for you in your area and could gain some power as well.

Isnt that y cars have Inlet aircharge temp sensor. I thought altitude only changed air density. And you can compensate for all that your talking about with timing. Thats y your car pulls and adds timing ass needed

high and low pressure weather systems as well as humidity will effect air density, as well as temp.

Any mass produced parts will have flaws. If you think they dont your only hurting yourself from learning potential problems. Go back and reread that thread you posted. Even stock maf transfer curves can be modified slightly for best performance and driveability.

The computer can compensate for almost anything outside of normal parameters. The point to tuning is so the computer doesnt have to make the large changes anymore. It only has to fine fine tune the combo from your new starting point that not every car has.

OK so I have a huge update

I was going to get my car tune this Tuesday and was getting ready to head out the next morning thinking the shop was in Bakersfield but it turned out to be in L.A so there was no way i was driving 5 hours to get my car tuned so i ended up calling Dirty Dirty Racing and the guy was super helpful and has amazing customer service...

So after ordering the chip he sent me a mod list and i filled it out and send it back. My chip is suppose to be here Friday.. So I went out to the garage and installed the 24lb injectors with my stock mass air and HOOLLLLLLYYYYYY SHIITTTT my car is way way way faster ....lol lol lol

The car shits and gets like a mo fo yaaaaaaa

The car revs up so fast its like i finally feel like the money i spend was worth it. THANK GOD ...

Also thats with a stock mass air not calibrated for 24lb injectors so i cant wait to install the chip ......

So TTocs you need to install your 24lb injectors asap bro

ah no been in there for 2 yrs in prep for this upgrade. your late to the party.

So you left the tuning place hangin and didn't show up? I hope at least you called.

I also hope that your mail order chip does better then mine or you will be right back on the dyno. You do not have any data logging ability do you? I was supposed to be on the dyno today as I type but instead I am back in the hospital. I felt bad cancelling with 24 hrs notice but they were cool about it since it was health related.

probably runnin really rich with the new injectors. I Would not drive it all that much for fear of fouling the plugs before the chip gets there. I am not adding gauges so that I can monitor it all as well as data log info to help tune.

When you ordered your chip did you tell them everything your car has ?

I'm happy with how fast it is now .. The car is fucking fast dude... Cant believe how fast it is lol lol I ported the shit out of my heads so I'm thinking thats making a difference for sure... I talk to lots of people about dirty dirty racing and they all said it was the single best mod they have ever done to there cars with H/C/I and you can get the software later to re burn new chips later for only $190 dollars ...

Im really happy with how it pulls now just adding injectors ... I hope you get better and yes i told the shop i was not coming it was his fault i asked him if he was located in Bakersfield and he told me yes so that was the only reason i was going to him ... O well

And the car is not running rich at all at least i cant smell fuel hella bad at idle but im installing a wideband today and getting the chip installed Friday..

When you drive your car does it rev up fast ?

After I installed the 24's the car revs so fast its fucking crazy ....

I read nothing but good reviews about bama as well. and yes they had a complete list of everything in the car. I have free tunes for life but I really do not have the confidence in mail order chips as there can be too many variables that they do not know. Have they dynod cars in your climate before to know how the differences from there to here might be? Maybe the spark plugs are alittle fouled or possibly not perfectly spaced? The idea that someone across the country can take a list of you engine mods and then just take a spreadsheet of measurements from another car, ran on a different day in a different place and get it perfect is just a little crazy unless they have some jedi tricks. IT is a nice thought and yea people say that it was a miracle worker on their car but its not from what I have seen. I could do data loggin, send it back and wait for the retune but I would rather take the drive to the dyno and make sure its perfect. You can't substatute reading real world data, in the place you will drive it. maybe your tune will go better but I honestly just would not trust it until it was verified on the dyno. I got my chip just to get the car running as I could not afford the tune and needed to get it running but at no time did I not plan on putting it on the dyno as soon as I could afford it.

The bottom line is i needed a chip anyways and its way cheaper if i take it to a dyno and have him give me all the info i need and just call dirty dirty racing and have them put the exact info into my chip and email me a new tune and i up load it

I dont have to send it back like you do ..

I think your right but if the tuner is really really good he might be able to get you 10 to 15 more hp but I think my car is feeling amazing already and that was the problem with my car it drives perfect but did not feel any faster and its way faster so my problem was injectors were to small ...

You might have more wrong with your car then you think ...How does your car drive ?

take to a dyno and have him give you the info you need? How is that cheaper, they don't just give that stuff out? Car drives pretty well right now. no check engine lights, temp and pressures are all normal and with the exception of occasional bucking in 5th gear under 1500 rpms its flawless. Idle is a tad high at around 900 but it idles nicely and has a nice lope to it. Doesn't feel like it has much more then it did before but that is where the dyno will work for me. most people pick up more then 15 hp from what I have heard or they would not be willing to pay what it costs. Beyond that you have the reassurance that it was measured in real time at your location to ensure it is working properly. I guess you can play with the tune until its perfect and that sounds all nice and easy, but you have never pulled the computer down and got into the chip yet have ya? I do not want to do that anymore then I need too its more of a pia then I want to do regularly. I know I know nothing about tuning, afr's and all the little details that is needed to get the tune correct. I am technical enough that I know I can learn it but I would rather not learn(often from our mistakes) on my own vehicle with out anyone around me to help dig me out of any hole I should get myself into thinking that I suddenly know how to tune my computer.

I have a 8,000 dollars snap on code reader and it does and all kinds of sweet shit so i can reset my idle or do anything i want so that is a huge help on finding out what is wrong with my car .. But My car does not ever buck at all and the idle is spot on and the power is there now.

I understand what your saying but when you get a dyno tune you pay for a chip and tuning .. You needed a chip no matter what .. All you need to do is have it dynoed and get the air/fuel graph for a lot less and email dirty dirty racing and they can email me a perfect tune ....And all save hella money..

Thats why having a wide band helps

I think the guy at dirty dirty racing knows more then most of the people on this forums about tuning and he told me everything i needed to know and its all good.


P.S post some pics of your car so i can check it out
