60' what is so important about the first 60'
  well really its just a point of reference ,but that first 60' sure make a huge difference on the balance of the run .
usually if it doesn't go well the rest of the pass follows poorly, but when its smooth and consistent the balance of the run just seams way better as well .

racers look for consistency and having a car that is all over the map on Launch is no fun and a consistent looser   .
BUT if you can nail out back to back 60' times you are defiantly having the advantage .
for me I was all over the map , this not only sucks but is hard on driveline as well as it does not allow you to judge your cars performance down the track
as your MPH and E.T are also all over the map .
with the ECMS installed I have been able to nail out very low consistent 60' times which allows me to better judge my vehicle REAL performance potential .
I have averaged depending on the day anywhere  from 4-6 passes in a row between 1.404 - 1.420 sec ,very smooth and consistent .

lets look at 2 passes in this case run #4 (10.112 @139.99) and run #6 (9.83 @ 143.44)
    yes if you look at the tabs its session #5 and 7 . that ia because session#1 is always a pretest for me anyway .

  first run#4 ,like I said I was testing different ECMS settings and this one was very good .
the 1st marker line (left)is the point the vehicle starts to move and the 2nd line (right) is 60' mark 1:30.60 + 1.412 = 1:32.01
 lets start from the bottom up .note; look closely at each point of change and see what point lines up with what .
RED - that is the point the ECMS solenoid energises  and 1.15 sec later it shuts off
YELLOW - clutch position ,notice it starts to engage first then at a specific point the RED ( ECMS solenoid energises )
BLACK - sideways G force , not bad a small push left then snaps back during shift to 2nd ( time to add preload to left torsion huh?)
GREEN - RPM follow it and see if you can figure out whats happening
BLUE - G force forward acceleration , line up with point the ECMS solenoid energises, again see what it line up with



  run#6 ,like I said I was testing different ECMS settings and this one was set very aggressive (hmm) .
the 1st marker line (left)is the point the vehicle starts to move and the 2nd line (right) is 60' mark 54.72 + 1.445 = 56.16 sec
 again lets start from the bottom up .note; look closely at each point of change and see what point lines up with what .
RED - that is the point the ECMS solenoid energises  and 1.15 sec later it shuts off
YELLOW - clutch position ,notice it starts to engage first then at a specific point the RED ( ECMS solenoid energises )
BLACK - sideways G force , yep help shows things were not as fwd but obvious issue of some type
GREEN - RPM focuss on rpm rise at point between blue peaks
BLUE - G force forward acceleration , hmm something not good car is obviously pulls hard to 2 g , holds there then looses acceleration then regains it .

now you can see how important data is and what you can start to learn from it , making notes as soon as you get back to trailer ,making notes on time slips ect .
also now take this data and if you are lucky enough to have a video watch it slowly frame by frame and plot against your data .
you will see a lot



lets see how this shows up on the computer screen , not sure if its clear enough but will try .
   overlay is the option of taking any segment from 1 session and pasting it onto another session for comparison   ,so I have clipped the same Launch section from run #4 and overlaid it onto run #6
using the same point of foreword acceleration and solenoid engagement as the reference point .
I have removed the sideways force just to make things easier to see .

now remember the ONLY difference on this pass was ECMS settings . which was a combination of engagement point and rate of engagement
 -- RED - same point solenoid is energised and still de-energised 1.5 sec later ( time can easily be cut to .5-.7 sec )as its work is performed way earlier
-- YELLOW - clutch position -  solid yellow 1.445 vs the dotted yellow 1.412 . solid yellow (AGRESSIVE)  starting point .  then climbs fast to 2nd point then climbs fast again to 3rd plateau or full engagement .
where as the dotted yellow line (LESS AGRESSIVE and SMOOTHER) same starting point  . then climbs slower to 2nd point and flat lines there before smoothly climbing to  3rd plateau or full engagement .
what's happening here is the settings in the ECMS is controlling the clutch engagement rate as well as holding a calculated amount of slip before disengaging and controlling rate to full engagement , pretty f--- cool huh  .shit works and like I said its a complete topic on its own but further testing with my USA boys are on hold due to covid  .
-- BLUE and GREEN -- this needs to be looked at together .lets focus on the solid BLUE (g force/acceleration) and Solid GREEN (RPM).
from the vertical line we see the blue line spike up to 2 g's and at the same time the rpm drops from 5600 to like 5300 rpm , then both BLUE and GREEN traces flat line (that is the rear suspension planting down hard most likely on the end stops ) this causes the wheels to spin a bit so the RPM climbs fast as well as the G Force acceleration dropps quickly due to loss of forward acceleration , then about half way between the vertical lines the RPM rate starts to climb at a normal rate which is the same point the vehicle regains traction and the G Force acceleration climbs again .
So know look at the Dotted BLUE and GREEN lines the BLUE acceleration line is delayed and climes smoother as well as the RPM also climbes at the same controlled rate .
 I think you can figure out what's going on here and what was learned from both passes .also what works better for my vehicle .
yep so now you see what a racer look at consistent smooth launches and 60' times -
so you can think like this kindove . 1.445 - 1.412 =.033 sec so 9.830 sec - .033 sec = 9.797 sec .
 I know this is a lot to take in god only covered 60' but hope it makes sense the rest is easy  and I know I'm not giving away to much on ECMS as its a Huge Topic in itself and has  taken years to get to this point

well last piece of the 8.50 cert completed .

  modified the bottom window net bar with rod-end so I could adjust as needed , the 2 bottom brackets are also slotted
to allow for net stretch so I can pull it tight again if needed .
very happy worked out great



lower bar inserted through lower window net and bolted to brackets .
fits and works very well



and with the door closed sfi tag and stroud tag outa view .



  now the window net did not need to be installed to be certified, but I just wanted the interior done ,
So can now check that off the list .
  guess its time to pull the motor out for engine maintenance.
good thing I cleaned the shop

The first person that can actually come and pick them up gets them. A FREE  pair of 1955-67 Bus Front Windshields. These are used, and I pulled them out of a bus. They aren't original, and have been made out of 1/4" laminated glass, original size is 5mm. They will fit fine. No scratches, no cracks, no bubbles, great shape...

this is the data run from running 9.8 sec . looks real good .huh ?
well for me anyways  because I'm used to looking at it . and I see some issues right away as well as key information I was looking for .
now the program I use is from innovate motorsports called logworks , real easy to use and play with .
of course there are bells and whistles but also great programs to configure and map your recorded data .
everything is in the end just a 0-5v input with exception of rpm and you configure from there .
if you want examples let me know .anyway lets expand areas and break it down into what I'm looking at .
               

nothing beats the old seat of the pants tuning ! only you know what it felt like , sounded like ,and performed like .
so after every run I make notes and usually my girls help entre data and keep notes to help in review on the spot or later .
  this 9.8 sec pass was far from perfect but shows I'm getting real good at complete vehicle tuning. there is so much more than making some power .
I was still setting up suspension , shift points , ECMS control , boost curves ect ect but figured it was time to really see if I was making headway .
  Launch - not my best but still another low 1.4 60 foot , so what did if feel like .I could tell there was a bit of sideways slip . maybe due to tire spin?
or bad weight transfer . well lets look .
first these are all the items I log and can select or deselect any of them at any time
               

so pull up the hide channels and turn off what I don't need as well as for your ease of viewing inverted my clutch pedal reading
               

so what have I done , first expanded the view
