LUCAS 120LB Low Z Tuning problems......

[Boostedls87]

I have a 87 rx7 with a swapped chevy 5.3 t78, 2.5bar map 120lbs low z injectors with a versafueler driver box.

The problem with the car is there is a lean spike when u tap the gas then it clears out after you get up into the higher map area. We have messed with the transient fuel and the ve table a little and didnt make much for progress. I got a voltage table to injector ms but im not sure where u would enter this in on hp tuners or if it is any use.

volt ms
14.5 0.70
14 0.74
13 0.81
12 0.90
11 0.96
10 1.07
9 1.23
8 1.45

We are kinda stuck and out of ideas so if anyone has any information to help that would be awesome.

thanks
