Feedback On Tune

[jhjones]

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...)

^^ what he said

[jhjones]

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.

The oil in the piping can cause detonation, which will crack ringlands, depends which came first, the cracked ringlands, or the oil in the piping

Looks like a fair bit of timing in there......

For reference here is discopotato03 s tune on e70. From his home tuning viper link thread.

You have more timing than that in certain areas,which I would say is your problem.

Timing isn't that bad, however there's a massive spike between 3500 4000rpm at 0.8 which o believe is where your car is knocking off its tits?

[Badgaz]

it doesn't look like much attention has been given to your fueling on wot either.

[jhjones]

I bought the car like this. The fuel map having same values from 60-120kpa is whats worrying me. 60kpa = 8.7psi, 80kpa = 11.6psi, 90kpa = 13.1psi.

[Ben C34]

As I said, shit tune.

That sucks man.

[Badgaz]

I would certainly not put this tune on your repaired or replaced motor....definately factor in a tune to your fixing equations.

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.

Lol oh f**k that's a time bomb

Time for a stock 30 replacement.

Checking map is serious business
