Blew my 612hp motor the day after I got it tuned

Got my car retuned by the same people that tuned it last time (800 miles ago). The setup only has 800 miles on it. Car made 612 @ 28psi tuned on crome. When the guy tuned the car he told me his computer he used to tune it had a few burnt circuits in it from a few miswired things before he started but he was not sure. (Could be something but could be nothing) With his computer it ideled fine and when I pluged mine in it was at 2000. He said it was the iacv that was messed in his computer, so thats why I tought it was ideling funny. The whole tune both times cost me $725. The reasone I took it back again was because my boost controller was fed and it would only make 22psi so I wanted to get a retune for higher boost.

Yesterday I go to the track, never boosted since the dyno tune. 1st pass car feels ok it was warm from driving a hour there (car cooled down for about an hour) it runs a 11.0 at 136mph. Second pass it blew, I got about 3/4 way down the track and it felt like there was a loss of power no pinging or anything so I got off it and it ran a 10.9 at 125mph. It also melted a few of the plugs along with the pistons!

Ouch man, I’m sorry to see it. You think it was because of the tune?

:dunno: , up for more pics

bummer

Did you datalog that run? What was the AFR like? Do you have a knock sensor installed?

No log files on that run, and no knock sensor

Maybe during your next build you should consider a knock sensor. TurboXS, I believe, makes a good knock sensor/warning system. If you see it light up, LIFT THROTTLE! Save your motor, and then get a tune that doesn’t detonate.

ouch! that sucks man. sorry to hear that. what color was your car? silver?

ouch

No black integra

oh ok, didnt see you running

sorry to see jeff

those pics made me make an icky face… that’s some ugly shit man

Holy F%&^!! ive never seen a honda piston melted soo bad. sorry to hear about your luck…atleast it happened now and not the beginning of the season

wow that is some severe damage. im not an expert but it looks like detonation due to the cracked ring lands on most pistons and straight lean on the one that is melted. on forged je pistons too, damn.

im glad i run Wiseco’s not JE’s ?

I think any piston would have melted under that much heat.

yeah, but everyone i know hates atleast one of the 4 following pistons for a honda: CP, JE, Wiseco or Arias. but your right…i dont think anypiston could’ve survived that.

ouch sorry to see that

that is crazy…

worst tune eva
