Testing: 5.7L Raised Shift Points

We'll I decided to go out to a small straight secluded road to do a little testing with the new raised shift points from Diablo. (This is with using the 93Oct tune and running WOT from 20-95)

Day 1
Stock:
30-50: 1.660
30-70: 4.013
30-80: 5.603
30-90: 7.386

6200:
30-50: 1.476
30-70: 4.035
30-80: 5.315
30-90: 7.278
Note: 30-50 & 30-80 are a little distored because of the chirp from 1-2 and 2-3 (plus it began to sprinkle after the stock run, so roads didn't hold much traction when shifting)

6400:
30-50: 1.72
30-70: 4.157
30-80: 6.076
30-90: 8.064
Note: Not sure if traction control became an issue from the damp roads, but after seeing the results I didn't test the 6400 shift point again lol

Day 2
Stock run #1
30-50: 1.667
30-70: 4.050
30-80: 5.647
30-90: 7.394

Stock run #2
30-50: 1.661
30-70: 4.023
30-80: 5.655
30-90: 7.411

6200 run #1
30-50: 1.479
30-70: 3.936
30-80: 5.346
30-90: 7.126

6200 run #2
30-50: 1.387
30-70: 3.986
30-80: 5.467
30-90: 7.377

6200 run #3
30-50: 1.424
30-70: 4.028
30-80: 5.470
30-90: 7.280
Note: Using the 6200 shift point, 1-2 and 2-3 shifts may have distored the results for 30-50 and 30-80, but none the less 30-90 has improved a good amount

I really would like to do more testing with some better tires though, 1-2 chirp is a little more pronounced now with the new shift points. The speedometer will jump up about 10 mph when it shifts out of 1st, so I'm sure I'm losing some on the table with that as well. So far though, I feel that the 6200 shift point is the best, I know 1-2 tenths doesn't seem like much but I'm happy with it! We'll see how things go at the track once I go back

 

I had Jack update my predator this past weekend and we loaded up the economy tune with some changes.

I had Jack change all the fan setting and the shift points RPM's and WOW!!Man , this thing just launches!! I did a WOT start and watched it shift past the 6000 point. and when it went to second there was no delay. and this was with the Eco tuned installed.(think it is far better than the stock tune for sure) Now as far as gas milage is concerned, I do think it gets better overall which means to me that I can goose it and run out some gears but I can cruise some and not burn as much gas. so far on this tank, I have over 180 hwy miles and the rest is intown driving and I am around 21 miles a gallon. before I would be around 17-18 MPG under the same circumstances.

Later on I may just load up the 91 tune and put some 93 oct. gas in it to see if it will chrip 2nd gear.

 

I guess you make more than $9.35 an hour

 

LOL, I've put over 100 passes on her so far

 

Sickr, have you seen the new crom Diablo released? lol The new shift points are in both autostick and D. Why would our tachs be off? I can give you proof our cars are reving to 6400 (logs and dyno charts). Yes I understand that its important for where the next gear comes into play, which is why I thought the new shift points would help. Instead of dropping the rpms down to 3500 its drops it to just over 4000 where our tq really kicks in. You can adjust the raised shiftpoints for 6200rpms and 6400rpms. The only reason 6400rpms doesn't help is because our stock cams let the power fall off after 6200.
Plus the proof is up there ^^ 6200rpm shift points improve performance

 

Hope it sounds like a different car in a good way lol. I needa hear it outside the car though, so you need to drive mine with them open lol

 

Here's a ride along with Jack in Black Voodoo!
Sorry for the crappy sound quality, I left the closed back on the Go-Pro, so everything is muffled. I'm only suppose to use the closed back for 100+mph runs lol.



We may have to make more videos...

 

OffTopic; but...

Hey Jack, here's the reason my RSA's looked like slicks when you took them off..
