Pulling timing at 26psi. Can anyone tell what's wrong ?

[twinturbos]

Hey,
So I went out for a night to do some pulls and my car seems to be pulling timing at 26psi. There are some pulls where it's fine and some other pulls where it goes crazy and pulls timing. I'm not very good at reading logs, is anyone able to tell what's wrong ?

Would be easier to help you with some insight into your mods, conditions etc..
Also, who is tuning your car? You should start with your tuner.
Your timing looks messy.
Your boost target is 26psi and you're going over that pretty regularly which can pull timing too.
Your trims seem a bit far off from one another and not too happy.
With all these corrections it seems like you've got bad gas or too much boost/timing for the fuel you're using.

You need meth.

Its a slightly modded ots mhd single turbo tune.
Running 6266bb docrace kit on 94 octane + 50/50wmi.

You need meth.

I am.

I woudn't trust an OTS tune with your setup, as you're running meth, lots of boost and some pump gas.

You spent all this money on your car, on the turbo kit, everything, and you don't want to spend another 350-600 on dialing it in safely? Contact Ken @WedgePerformance and get it done. You'll feel a night and day difference in power and smoothness, and you won't need to worry if you're on the edge or not.
Until then, I'd turn boost down to 18psi and take another log to see how that looks compared.

Can't understand the logic here.

 

[twinturbos]

It's not about spending the money for the tune. It's about finding someone who's willing to tune the car with the stuff that's on it and that I'm comfortable with aka JB4. I also would like to be able to keep multiple maps.

 

[V8bait]

You're using mhd ots maps with jb4? Plenty tuners around that can handle both including myself but definitely need to have a chat about your setup because it sounds like you're trying to run android on your iPhone.

May as well run 20 psi with good timing rather than 26 with timing pulls all over the place and fuel trims out of whack. Staying on it when the car is shouting stop is one reason alot of these cars don't last long. You want clean timing before you progress to more and more boost or timing.

This is your limit (22psi) with the current fuel you have, even 1psi less might clean it up more and give you some flexibility with different weather conditions. You can try 100% meth or add some E85 if you have it available, increase boost and see what timing looks like from there.
