Feedback On Tune


Recommended Posts

Hi, my engine recently dropped compression on 2 cylinders and I suspect cracked ringlands due to the smoke and blowby. I was wondering if someone could have a look at the tune on the ECU and give feedback on it. Thanks.

RB25DET, stock turbo 12psi, Link G4

Well I'll call it right now a shit tune if it cracked ringlands.

(Haven't looked at it,but isn't that obvious, unless some injectors or fuel pump failed or over boost etc...)

The car did 10 laps around the track before I noticed oil all through the intercooler piping, no catch can at the time. Did a compression test, 155-160 on all six.I installed a catch can and noticed it filled 1 litre with just hard street driving and one night at the drags. Did a compression test and cylinders 1,2 dropped down to 115, and 130.

curious, when are you hitting max boost? if it's around 3300~3700rpm then there's way too much timing

Stock turbo dude, can see why it pinged to death.
