Here’s a datapoint. This data is from last summer; I’ve had zero problems. The original map Bytetronik sent prompted the engine to boost waaaaay too high; they updated it to stay in a safer zone. Usually I don’t see any higher than 16. Below you can see a max of 18psi boost. Ambient and intake air temperatures are also charted.
(JJ and I have also chatted privately about this in the past, but I figure it is good general info to share.)
Horizontal axis is time (seconds elapsed from start of data log) not speed.
Anyway, no powertrain mods of any sort except the tune. It’s a little twitchy in sport mode, with a little bit of surge, but in normal mode it acts, well, normal. If normal is over 200hp, at least. :-)
I am also running a Bytetronik stage 2 tune. I typically see 16-19 PSI in the summer, 14-17 during the winter. I have only ever spiked to 20.9 psi once. In all fairness (it was a 90 degree night and I did go a little nuts).
When i I had a bunch of tunes in the past, I recalled everyone at 22+psi or so.
Seems like motors are blowing so wanted to see what tuners are using now. Unless people are blowing motors from increased timing and not boost.
Last i spoke to BT, they said new Stage 2 maps rely less on boost and more on timing. Makes sense why this would be safer considering that these motors dont tolerate heat and detonation very well.
Ive been beating the s*** out of my car on the new BT stage 2 map (always using shell gas) and everything seems good so far... No holes in pistons yet!
Oh yes. It’s been a while.
I run meth now for extra safety.
You back on the same tuner? Or different one?
I cant remember what u had in the past.
Couple of years on now, but how has the meth kit been? Are you using snow performance? Lastly, are you using the washer fluid tank of did you put the tank in the back?
I'm running dervtech stage 1 and currently blending ethanol to E15 since fuel on the west coast of Canada isn't great.
