My Consult diagnostic cable made by old Blazt tends to annoyingly freeze the laptop at random whilst datalogging with NissanDataScan 
I thought it was electrical interference but I noticed that simply nudging the cable will disrupt the signal & freeze the screen, so there must be a loose/bad connection?
The old cable connector loosed dirty inside, probably dirty terminals so I cleaned the pins
Here's all the terminals on my 1998 consult connector
& close look at the Blazt USB Nissan Consult control board
Now it can datalog without freezing.
Went for a datalog drive to compair the current setup with the old runs
Subjectively I think she feels faster but it might be increased NVH
Comparing all the 2nd gear 3k-7k rpm pulls along the same slip road on all my videos treating it like a dyno pull, the data says all my N/A setups have exactly the same acceleration
New 4-1 mani with big exhaust pulls the same as my old 421 header with slim exhaust, & the previous oem mani that's been enlarged to 2.25" & even when I stripped the lighter interior
But comparing the datalog also told me the MAF is reading lower/worn/dirty, the new TPS can read higher, new loom has less voltage drop.
Resulting in higher injector duty & period = richer AFR = little more power
But the heavier big exhaust, subwoofer, brakes & wheels might have counteracted the higher HP?
Today I took a long gentle 60mph cruise on a chilly day to finally test if the removed PAS & smooth 4-1 manifold helped reduce some drag loss?
Answer is nope, she did the same 44-46mpg as before
Guess I'll reinstall the power steering cos it doesn't affect mpg and parking with manual rack & LSD has been an absolute pain lol
