So I'm a MAF ignoramous...

I can't figure out how the fueling works on a 6E car. In TP, where is the equivalent table for fueling by MAF vs RPM? I.e., like VE vs MAP and RPM on a 8D car? This is my first attempt at evaluating a MAF car...

I want to build a histogram in TP to plot this member's BLM's vs RPM and MAF, but I want to build the table around how the bin is structured (again, similar to the BLM history in 8D that mimic's the VE table in its structure).

 

I use gps vs rpm to see where the maf table needs to be changed.
int vs rpm and blm vs rpm.

There is none

you kinda compare maf output values and your air fuel and change the maf tables at the points where you see the grams sec values lol. Like if you are cruisin at 20 g/s and are lean, go to table 2 or 3, wherever you see 20 and change the two cells around where 20 is. Increase will add fuel. If you could read and log maf voltage vs rpm that would help


if wot, go use the pe enrichment percent vs rpm table. Tune it like a ve table. Highest air flow is peak torque so usualy see most fuel at that rpm. Then it will dip just after peak torque and rise again toward peak hp. Usually. Unless peak trq and hp rpms are close together, it may all be similar curve

 

cool thanks guys...

 

Let me know if this makes sense...

So I generated this histogram... I plotted BLM vs raw MAF counts and engine RPM. The MAF column increments every 5.1 counts across 50 table entries (255/50).

Once the playback populates the histogram, I can copy it out to an excel file... at which point I guess I need to convert the raw counts to volts in order to see what tables are impacted and which airflow values to modify?
