plz tell me its just bc i need a tune now
 

ok just did a single swap next stop is dyno tune
im hoping everything is working ok but the thing is as of right now it barely if at all boosts. when i get on it lightly if anything it creats more vac then after geting off the throtle no matter how hard i was on the gas the rpms will bounce till it dies. if i start it and just let it idle and not mess with it it idles as if theirs nothing going on no prob. any ideas im really hoping its bc i need a tune and that's all

Pictures of set up.

how do i post pics on here?
also i have a vid of it as well.
the setup is a turbonetics T66

here is a link to see the kit in the car
im trying to get the vid up

need more information to make a logical suggestion...

What is the setup... ecu, engine, turbo...

Are all of your vacuum line hooked up? what about your map sensor?

Im not a "tuner" but I would think a super lean condition would cause that type of behavior...

everything is connected
stock ecu and everything im takin it in for a soft tune on 8 psi asap
stock 13b

vid and yes i know i have an exhaust leack from down pipe to mid cat

Your single on a stock ecu? That's a big no no. Car can't even be tuned on stock ecu.

i was told by the shop they can tune the stock ecu.
but is this a tune issue?
also when idle its a -.5bar

Which shop told you they could tune the stock ecu? I suggest finding a new shop.

ok well if i need to get one i can go get an apexi power fc i got the cash for it
but i need to know whats going on with the car right now if it is a tune prob ill go buy the fc and go tune it

im not an expert on this but with a set up like yours the stock ecu should of not even be an option. also, the question you ask has kinda already been answerd, up grade your ecu! even if some how you get the car to run "ok" does not mean you should keep that stock ecu for a single turbo car like yours.

ok ill be geting a pfc

Are you trying to get boost in neutral?

if that is what you are doing you will get almost nothing.

You need to stop working on your car, do some research, and become informed. I only say this because you are going to end up spending a fortune on all your misinformed actions.

NEVER use a stock ecu with a single setup.
You WILL need to upgrade your fuel system.

You've posted little info on your setup and ask us to tell you if it's the tune. Give a detailed list of what you did during your swap. We'll go from there.

we took all the stock twins stuff out all lined that were takin off of the twins were caped off. ran a vac line from side of the top of the waist gate to the frunt of the turbo. vac line from intake man to bov. re ran the oil lines and re routed the coolent lines.

Get you some 1600cc injectors, supra pump and the PFC. Do that or you be adding a new motor to your list if you are not there already.

Oh and a new tuner because the one you have knows Jack shit about your car.

Wow. There is so much wrong with what you are trying to do at the moment and you are receiving solid advice from the forum. Three major points:

1) Find a new Shop who actually knows about FD's.
2) Stop working on your car until you do.
3) Find a new Shop who actually knows about FD's.

ok ya talked to some guys got a new tune shop that knows there sh**
im geting a power fc as we speak
next thing im lookin for is fuel upgrade

Do not drive that car till you get a power fc fuel system and a tune.

Sounds like you have a badger hidden some where in your engine bay and he is pissed

You were already told what was needed in your original thread:

https://www.rx7club.com/single-turbo-rx-7s-23/questions-reguarding-new-single-setup-what-more-should-i-get-948826/

I would suggest listening to the people on this forum rather than some random "tuning shop".

You have a problem besides the wrong ECU. Take your car to a rotary specialist before you cost yourself several thousand dollars to replace your engine.

wow. Did you clean up and remove the sequential control system stuff and use block off plates? It doesn't look like it from what I can see.

For fuel setup I'd go with some ID injectors for simplicity and ease of installation.

Time for some serious research...not having the supporting mods and trying to get it to boost on a stock ECU is proof of that. You're lucky it didn't boost because you would have been buying a new engine and probably replacing your turbo when all those apex seal pieces started flying through it.

oh so its this guy....

surprised the engine is still intact.

You live in Cali, there are loads of good shops there, not like you're in Wasilla Alaska or something. There are guys in some states that would kill to have local access to those shops.

These guys may seem harsh but the kind of rebuild you are heading for would likely start at $5k and could go up from there.

no i have not taking the rats nest out yet i just caped everything. wold this be part of or all of the prob i have for now?

It may be part of it, small compared to everything else that is wrong though.

Take it to a shop that knows rotaries, or you will blow the motor.

ok so update did some research and and found out i had the vac line in the wrong spot for the waist gate so i changed it and put it in the right location and now when i hit the gas at all it wont die it just bounces for a sec and then gos back to a 500-700 rpm idle

poor engine sorry you are going to die soon.

thanks for the help

car is not moving till have my ecu and im towing it to a dyno shop

By dyno shop do you mean rotary specialist?

i mean a shop the dus dyno tuning theres a few places out here that have tuned 13bs good

So your plan is to just plug in a PFC and then tow it to the dyno and attempt to get it tuned?

Wow...

This thread = FAIL

UPGRADE YOUR FUEL SYSTEM!!! BIGGER INJECTORS, SUPRA PUMP!!!!

You removed the air pump. WHY did you keep the rats nest??????

TAKE IT TO A ROTARY SPECIALIST!!!!! NOT A TUNING SHOP!!

Yeah if you want to see it done right see this guys single turbo build thread ^^

I can see how this car will end up. There will be a f/s thread soon selling the car as a roller. Then he will go and buy another type of car and bad mouth FDs because they blow up too easy because he got his stock ECU "tuned".

no this car will not be sold i know its going to take awile im in no rush on it
and power fc i just bought will be shipped on mo or tu.

what are some places near stockton, ca that u wold recommend?

You'll need to travel a bit to find a shop that knows what they are doing. And a shop that knows what they are doing will cost you less than taking it to multiple shops that don't.


Do you even have the piping to the intercooler? You just have a bunch of piping from the turbo to the IC inlet but it isn't even properly connected. Then you have nothing from the outlet of the IC to where it should connect to the stock "elbow".

yes i got all the piping

Ricks Rotary in the bay area has a good reputation. Please take it there before you blow the engine.

Also, please learn to type something legible!!!

ok ima look into there shop on mon.
will they be able to tune the power fc as well?

Look Mr209ttrx7, ask the guys on this forum for a known good tuner in your area. They want to help you. You are killing us out here! We don't want to see you have a bad experience. This isn't a piston engine that ANYONE can learn to tune over a weekend. A rotary is not a forgiving motor, however when properly tuned is mechanical genius. Please take the advice given.

ok ill be makin alot of calls to places to see if they have any experience with it evin if it means traveling

HOW are you controlling boost? (WG spring, boost controller)

The factory injectors can handle around 300whp, then it gets dangerous. If you haven't upgraded your fuel system, why are you even looking for a tune? A T66 is a good size turbo that can make over 300whp on 10psi likely. Why would you risk running out of injector?

You said that you are in no hurry, but your words are proving otherwise. Why don't you...

1. Remove the rats nest & block-off emissions properly.
2. Perform single turbo wiring harness modification. Test all connectors in the process.
3. Upgrade your fuel system properly. Including injectors, pump, fuel pressure regulator.
4. Find a quality rotary shop to review your car & setup with you, then tune it.

There is TONS of information on this forum. Start with the FAQ thread. You need to relax, and spend some time reading.

ok update parts coming in
power fc with commander and data logger
fuel upgrade parts such as 1680 injectors new fuel rail fuel regulator and resistors
also all the block off plates ill need
starting tomarow i will be starting the removal of the rats nest
