Broken Brz :( help

[brzcui]

what tune are you guys running on your cars? i'm definitely gonna look into retune the car because the dealership guys said it looks like a bad tune, but tuning comes after i fix the car completely

You don't have to diagnose your car before you take it to the shop. That's what a shop is for. What's wrong with you car is that the CEL is on and it stalls and runs like crap.

Take it to a shop. We've all probably been in over our head a bit, sounds like you made a hefty investment in an older modded car. It's only going to cost more money.

In my experience, people don't flip good solid cars. There's a reason he was moving it down the road so quickly.

That was where I was headed next.

yah i definitely learned my lesson on this one, he told me the reason he sold it is because his wife hates how much money he puts on to fix the car and it's too small too low... and he needs some money back from this car to start his jeep project

[brzcui]

i called two shops today, one of the shops works with edelbrock superchargers but only on mustangs and the other shop has no experience with any brz but has worked on turbo builds before, these are the two shops that i can possibly drive myself to just for a check? another option would be the tuning shop i had my car in two weeks ago, but its about 45 miles away and i don't really feel like driving an hour with the check engine light on, what should i do tho?

[brzcui]

or i can take it to the shop down the street, i called them a while ago when i didn't have a ob2 scanner and they said they will charge me 160 bucks to pull a code lol

Wild guess... 4 door JK with a ton of bolt on parts and angry eyes? Welcome to my damn neighborhood, the place is over run with hardcore rigs that will never see any dirt.

Find a shop that will work with you. You don't need everything fixed at once. You need it to run reliably, then tackle the other stuff.

ya it was a super old jeep with bolt on parts, he was planning on building it as his next daily and retiring the truck, definitely wasn't gonna take his jeep off roading

I wouldn't worry about the tune as much as I'd worry about the health of your supporting components. Each one of us has done different things to our cars, so comparing tune's wouldn't do you a bit of good. Do what Tcoat, Maslin, and DarkPirate have said and take it to a shop.

If you're in PA you should try motoeast they have a fairly good reputation

@brzcui



The shops your using dont seem to be doing good diagnostics
Diagnostics is npre than just reading cel codes and randomly replacing bits baeed on cel codes.


They need to log ecu fueling timing, port and direct injection times afr closed open loop fueling knock etc to work out whats going on.


Also trying to diagbose anything without acces to the ecu tune is going to be difficult as different tuners do things in different ways and if its ecutek it add functionality to the ecu via custom maps or speed density tuning.


Often port injectors are changed and MAP sensors changed when tuned for forced induction these changes need to be mapped into tune or car will run like crap.


Other common issues are intake and exhaust leaks, thes can often be deteced by logging ecu parameters like fuel trims or manifold pressures.


Also check the Direct injection computer is securly bolted up to side of engine will all three mount bolts that its only ground\earth.


Your going to need to take it to a shop that is familiar with brz\86 forced induction its unlikely any other shop will be able to help the shop will need diagnistic and logging tools for brz\86 and the tune system possibly ecutek that the car is tuned with

Hello brzcui and welcome to …. The Forum -

After reading all of your posts and the responses, I would strongly suggest that you sell that machine "as is". Just tell the prospective buyer that it's not running good and you have no idea what's wrong with it.

Let the buyer be a hero and figure it out.

Then, don't do that no more -

That may be a tad extreme. It could still be something very simple. The fact that it is so interment would sort of indicate that.

Imo if there are no unhealthy mechanical noises there's hope. Don't panic. Just get it to a qualified mechanic.
