Hi all,
I read some threads about the UTEC MAF mode, it's exactly what I'm doing on my 350Z, but I have the same problem with all the 2 logging software I'm trying: MPS_UTECLogger 3.0 and UTI 2.7.5.

The X axis of the tables is not compiled by TPS but with LOAD, so I can't read correctly the logs, because with this configuration the LOAD is not a good parameter.

Do you know any solution to raise the load to TPS with UTEC settings or change the reading X parameter to UTI or MPS software?

Thank you,
Nik

 

I don't understand you 100%, but if you are answering to configure the UTEC to use the TPS instead the MAF as LOAD value, you can't.

In the logs, or in the UTI tables what you see in the diferent columns is the % of MAF load from a minimum to a maximum.

 

Yes, but my LOAD values are very different from TPS values in the log, so I can't obtain a good table when logging, too many holes:
From 0% column I see a direct load jump to 60%-70%-80%, without intermediate values.


When using MAF mode fuel tuning, the load reference for columns 10%-100% is MAF voltage. The UTEC default MAF range is from 0 volts to 5 volts.
Load Site 10 - 20...
Min MAF 0.0 - 0.51...
Max MAF 0.5 - 1...


Do you think it can be wrong setting for MAF Minimum and Maximum Value for Mapping?
Maybe I must set the TPS threshold to lower value?

 

Yes, you have to play with your MIN - MAX MAF values. At the begining I also was only using column 50, 60, 70, 80 and 90. After a calibration in the MIN MAX values, I use all the columns.

 

Ok, I will try as soon as possible, thank you!

Just log from UTEC in it's native mode. Works much better. Not as pretty as UTI or MPS, but more reliable. In my case, UTI was lagging behind UTEC by a few lines. I never did figure out a work around. UTI is still pretty cool for a dashboard though, I just wouldn't base a tune off it.

Edit: You'll need a TXS Tuner to log in native mode.
