Extrapolating MAF data for 1.9 JTDM from 2.4Lt 80mm MAF

Postby AlfaEmre » Mon May 28, 2018 9:29 am

I did some Extrapolating from 80mm MAF data 32x1 from 2.4Lt to my 1.9lt JTDM. Can you review it. Did I managed to do it ?

2.4LT has 32x1
1.9Lt haz 57x1 but... last parts are not actual valuable data. all of them like 38.00 38.00 38.00

I read the 32x1 values and extrapolate them into real 57x1 data.

It did not worked as I expected. I think I will copy first 32x1 data then the rest into 57x1 area.

maybe I should copy "AFSCD_tLin_CUR" from 2.4Lt But I don't have damos, can you give me ??

One of my friend told me that. Is it good?

Maybe I would only set the ( 1C227E ) to 32 and copy first 32 data.

In my case MAF linearisation map is 57x1: first 32 numbers are from 2.4 Ø80mm MAF linearisation map and other 25 numbers are from 1.9 Ø70mm MAF linearisation map. It works in last three years with following map configuration:
a) on address 1C227E is: 00057 (length of map)
b) on address 1C2280 is: 02369 (first number in X-axis - pulse frequency in [μs], factor is 0.035714)
c) on address 1C22F2 is: 08500 (first number in Y-axis - airflow in [kg/h], factor is 0.1)

Also Car didnot want to go this morning. Like the gas pedal disconnected. Did not show any DTC, I had to unplug MAF to go to work? Is this that bad to have incorrect MAF data?

Also Should I copy more data from 2.4Lt MAF, and do I have to touch other maps after I finish the MAF.

I've test almost all the scenarios and nothing works. I don't know what to do. I think you guy use different sensor or different data.
After I load the file to Ecu, at first start, Engine runs good. Gas pedal seems to work. RPM built is good. But when ever I start to move the car. HP drops to 2HP, rpm built slows, I don't understand, at Stand Still car goes upto 4500rpm. Readings are good. Why this is happening. Maybe you forget something to tell me?

I don't give up, I need help. And proper help

So, where, at least, what data were taken for diagnosis, air intake?
