I picked up HP Tuners last week and finally got around to looking at the program tht was included in the Radix. One word stands out when talking about PE mode in my truck.... LEAN! We ended up adding about 20% more fuel to the PE adder table to get it to show consistent 950-960's on the O2's. It started in the 860-880 range.

I also noticed that it looks like most of the torque management was pulled out already in the superchips tune included. That was a big surprise. We looked at the timing through the runs and through the shifts and it never drops out as many have described TM in their trucks. I'm guessing it is because the H2 has the 4L65 stock. I'm a little curious as to how long the 4L65 will hold up considering that it doesn't have much TM anymore.

The torque reduction vs torque vs rpm table in the tranny TM table looked like the following-

The stock program had the following...

TQ 0 40 80 120 160 200 240 280 320 360 400 440 480 520 560 600 640
1-2 0 0 0 0 4 12 20 28 35 35 35 35 35 35 35 35 65
3-4 0 0 0 3 9 9 9 9 9 9 9 33 33 33 38 38 38

The Superchips has this...

1-2 0 0 0 2 2 2 2 2 2 2 2 2 2 2 2 2 2
2-3 0 0 0 0 0 0 0 2 2 2 2 2 2 2 2 2 2

If that isn't removal of torque management then I must not have a good grasp on the concept. Is there another area I'm missing?

I think there are various TM tables that need be edited for total removal

 

That is the main table though right?

 

I forgot to mention the shift point deal...

Factory H2 WOT shift points were retained in the Superchips tune-

1-2 = 5600
2-3 = 5200

Now they are -

1-2 = 5800
2-3 = 5800

Clearly my previous best 15.05 left a little on the table. I really should go run it again just to see but I don't think I'll get the chance before the E-fans go in. I'll bet it had a 14.8 in it with the higher shift points. It was in third way before the traps. Now it'll hit third right at or just before the traps.

The truck pulls harder with the additional WOT fuel and the higher shift points. I'm still very happy with the Radix.

superchips was 5600 and 5200? that does seem low

 

It retained the factory points in my application.

The injector constant was very good and so were the LT fuel trims. Driveability is very good.
