So my car originally had an unknown tune done by a previous owner many years ago. Due to some electronic issues, my ecu recently had to be reflashed back to stock. My car has k16/24 hybrid turbos, exhaust with 100 cell cats, upgraded diverters, boost controller, and evoms headers.

I plan to eventually re-tune the car, but over winter/spring I'm planning on doing some hardware changes so I'd rather do the tune after.

So is my car safe to run on the stock tune with these components? I also plan to do a couple of autocross and winter track days before getting to the re-tune stage. Should I worry? As it is now with the stock tune, the car will boost to 0.8 bar, but I have no data logging capability so I don't know what's going on inside. With the old tune it would safely boost to 1-1.1bar.

Also, anyone know if any of the Cobb OTS tunes would safely work with my setup for now? I see Cobb units are 10% off right now. If I could buy an Accessport, use the OTS tune for now, then get a custom tune in summer, I'd be happy.

Thanks.

 

Safe to drive normally maybe, but stock tune, A/M turbos and you want to race it? What do you think?

 

I don't know. That's why I ask. Is 0.8bar from my k16/24 too much for the stock tune?

 

.8 bar on stock turbos and .8 bar on those is diff. I would not be beating on the car on a stock tune, def not. Again, driving easily, sure. But I'd tune it before breaking something.

 

Buy the Cobb; it'll work well with your setup, it's what I run.

Once I have finished fiddling with mine, I will have some more focused tuning done to tighten it up a bunch and optimize power/drivability.

 

Thanks! Are you running larger turbos than the stock K16?

 

I have an X50, so I am running K24s. At some point, I will replace them with new units, but right now, it screams really nicely.

 

It will be fine on stock, you just won't be getting the most out of your setup.

Go with a custom tune not an OTS one. I recommend @Kevin from UMW.

 

Are you using the OTS X50 specific map found on the Cobb site?

 

Yes, until I can find the time to get a custom one...

 

Why not spend the 900 odd dollars and have Kevin do a bespoke tune for it?

 

if you have injectors, you cant run the car. afr will be off, rich if you have bigger injectors. I wouldn't drive a car at all with the wrong tune on it. Just do what everyone above said and talk to your favorite tuner and get it fixed. run rich and foul some plus = pain in the *** to change them all. run lean and maybe blow up your motor even without the boost. Sounds like lose/lose.

 

Send me a email and we can get a plan for your tuning. the first thing is to datalog and set the benchlines. At idle and on the road..
If you were running large injectors you would be running pig rich. Your idle would be all over the place.
You also need to make sure that you have a stock MAF a Hitachi MAF will wreck your fueling.
