Hello, help please! There is a car A6 C5 Allroad, me7. 1... I want to remove the MAF sensor and instead put the Absolute Pressure Sensor with a Temperature Sensor. Tell me how it can be implemented? There is TunerPro but I have not found where you can change the type of sensor, as well as add a calibration map, calibration of sensors and air flow on this sensor. And how to connect it to the ECU auto?? Thanks in advance!

Converting ME7 to speed density properly is a lot of work.

Do you have experience in ASM?

I so understood work in assembler??

MAF is always primary load input in ME7, you cant get MAP as primary input unless as said you change a lot of crap.

Just I worked with ECU January 5.1, there it was possible to insert simply a card, to change a bit of type of the sensor and instead of MAF to connect MAP, then to calibrate ECU

Change the ECU is a possible solution. There is plug and play solution for Me7 which can run from MAP

i have a patch for sd on me7 if interested feel free to pm

More importantly what problem are you trying to solve? Running sd in an ECU designed for MAF introduces a ton of issues, even if you get a more or less decent hack for it.

and if you implement MAFless??

Again, what problem are you trying to solve by going MAFless?

The essence is to remove MAF since two independent zero filters are installed on each turbine and there is no place for MAF since there will be no common air pipe to the turbines. The air at the MAF to calculate not happen.

I dont think you seem to understand. This ecu is load/torque based, the primary load input comes from MAF. MAP is used for boost control on error checking... MAFless basically means running alpha N , which is essentially limp mode, but it does really bad on same load/rpm situations , and stuff like hills, temp changes and so on.

But the correction of the mixture is also performed by lambda probes, correct the calculation of the fuel mixture.

Which are narrowband so doesn't work on WOT

Is it possible to replace it with broadband?

Requires ASM modifications even more difficult than for speed density.

Again, what problem are you trying to solve?

Split intakes with 1 filter each side by the sound of it...

This ecu supports speed density control http://www.ignitronecu.com/

Can I read more?

for Russia, $ 1000 is very expensive!

Because you think you'll be getting a SD patch for anything less than that on the forum here or what? LOL you crack me up. NO, no one will give you such a patch for free, unless it's something copied from elsewhere and they have no clue how much time and effort went into writing such a patch. Hey, out of interest, did you put $20 rods in your engine?

1480$ in the motor already lies...

and Pro for free and words not was, but roll away 1,000$ for naked ECU, then still buy software to his align for me this seems a bit not is logical!

What software? The tuning software is free for the ECU.

Writing custom ASM is not free.

I showed him an ECU which is capable to run with speed density.

Better get an Easy Ecu 3, does its job fine.

Why wouldn't running the MAF on one bank and scale it *2 work ?

But yeah, go fully standalone if you need to run sd or alpha/n...
VEMS for example is not terribly expensive and nice to tune.

Retard alert here or what?

Run the MAF sensor in the cold pipe, we used to do that all the time on stock ECU Nissan setups. Usually produced more accurate airflow/intake temp readings too.

Down side is possible oil contamination on the hot wire in the MAFS, but that's not that bad.
