i have been testing pretty regular at my local 1/8 mile track, cant get to the 1/4 without driving through the 1/8, right... my car runs pretty consistant 7.6x-7.7x... i had the car tuned at mainstream and have put about 10,000 HARD miles on it, i have never altered the tune on the car, just the parameters and have moved the car from running 8.2s-8.3s down to where it is now...

well, last night i tried shifting the car sooner and lowered the rev limit down some... i notice the boost begins to fall off after 7500-8000ish so i figured i'd try it out... well just as i was getting ready to cross the line, it felt like boost cut hit... i assumed it was the rev limiter because usually when the car is making a strong pass, im shifting to 4th in the 1/8... i added a flow control valve that i was testing, so i knew a few things would be off, but this has me puzzled...

the setup
gsr block/b16 head/type r cams
750cc/ walbro 255
precision 6039/ tial wastegate/ topmount
full 3" exhaust
crv awd trans
made 440whp/285ft-lbs
toyo street tires
this is a full trim ex model ek, down to a spare tire/jack... 2800lb DD



this is a normal 1/4 mile, notice 1/8 mile mph

 

btw, the area of concern is around the 6.5 sec mark... look at the injector duty cycle... it abrubtly drops to 0%

 

Yeah, but you let off around 88mph which resulted in the low mph.
(edit) Nevermind. TPS is still 100-102% while rpm's were descending

 

You were on boost cut, the datalog shows it.

 

well i cant get the damn file to open at work... tried installing hondata, but either way, seems like the boost was only at around 18ish at the moment when it cut...

 

20.2 when it cut

 

ok, i'll trust you... on another note how can i adjust the map/psi graph so that i can see the boost actually graph... it defaults to 100 psi/ and i assume 100in/hg so what it actually makes looks like a flat line...

 

Maybe check out this link and go to sensor setup from the menu on the left:

Change the display min & max values???
