This is my first post on Third Gen which I believe is a great forum.
I am looking for some advive on a data log I did on a 1/8 mile run I did a a local drag strip.
I am using Tuner Pro RT with a Auto prom (165 ecm).
My car is a 89A Corvette 383 Mini Ram, AFR 195,FMS 30lb,58MM TB,224-230@050 cam.
What I was hoping is that someone could look at my data log which I have converted to an XL file and maybe offer some advice on improvements to the tune.
The base tune is by ED Wright and I have made some slight changes to his .
I do not have a WB yet so I am not sure how good the NB readings are at WOT.
I am still a newbe at this tuning stuff and I think I have read ever sticky.
BTW the car had a best of 7.98 @87.5 mph.
Any help is greatly appreciated.

 

Any sign that your bpw is being limited or capped at a constant value as rpm increases? This could be a concern.

I'm assuming that the MAF is maxed at 255 gm/sec at mid-high rpm and your adding extra fuel in PE. If your target AFR goes richer than 11:1, you may run into the bpw limitation.

 

You're leaning out after the MAF pegs around 4600 rpm.

Add more fuel in the RPM PE table so that your target AFR approaches 11:1 in a linear fashion between 4800 and 6400 rpm.

+ 11 % should result in an 11:1 target. Something like this for example:

4400 use present value (approx. -7 %) (12.7)
4800 -4%
5200 +0 % (12.0)
5600 +4 % (11.6)
6000 +8 % (11.3)
6400 +11% (11.0)
