alright i just had my car tuned and im trying to even out some rough spots. I was just wondering if i was on the right track.

here is my map at 14psi spiking to about 15/16psi 11.2 - 11.6 afr

334rwhp 277lbs tq




and here are the corrections i have made to it.



Here is my dyno map.

 

Which P rows were AFR tuned?

 

all of them.

 

Normally your maximum ms of injector time will occur near the point of maximum torque for the high boost rows.

Here are my maximum injector total ms value locations in my base map:
(P15, N15);( P16,N16);(P17, N15-N16);(P18,N15);(P19,N16). These are my rows for 8-16psi boost. My N columns are all within 1 column of each other.

Yours are scattered and LOW?;
(P15,N16);(P16,N11-N13);(P17,N11);(P18,N12),(P19,N13-N14).
Either poor AFR tuning, or inconsitant non linear boost control.

 

You did a "recalc base" before posting those numbers up right?

 

No? This is straght from my car being tuned. All i was doing was going back and getting some of the inconsistent numbers out of it.

I see how you are saying they are inconsistent.

What would you suggest i change than?

 

Your answer to this is inconclusived. Do you understand the question?

If it was just tuned, a good tuner would have re-calced the INJ MAP into the BASE MAP, or you could have done it. Viewing a base map only without an INJ MAP with data in it is useless!

 

If you try to clean up the values (smooth progression from left to right below the torque peak and right to left above the torque peak, and, from lower p rows to higher p rows) you can alter the tune and create lean and rich spots. Smoothing out the map needs to be done during the tune session.

If the entire map was tuned as you say, then you ran every boost level up to the map sensor limit from 2k to 8k??? And the tuner did not bother to smooth out the base map? It's tough to control boost to the center point of each row, so as you move up/down in boost and make base map fuel changes it's easy to alter the AFR for the adjacent boost levels. It can be done roughly but to get it spot on takes alot of time when trying to tune the entire map.

 

gotcha. yeah the dynapack lets you set limits on your speed and go up in speed at whateer rpm you would like to. Mine tuner wasnt trying to squeeze every last ounce of power of out the vehicle, it was more of a nice safe driveable tune.

334 is nothing to shake your head at. I guess i will just let it be than.

 

Look at your torque between 5200 - 6000rpm, it should have increased a little bit more there instead of flat lining. Most likely caused by timing being too retared, or fuel too rich. That should/can be fixed.
