R33 Tuning Issues!

[RB_purr]

Hey guys done a fair bit of searching on this but have been unsuccessful...

R33 gtst series 2 rb25det

Splitfire packs

Apexi pod

Boost tee

FMIC

Stock turbo

Apexi power fc

So guys just had an apexi power fc installed on the 33 and the idle is rough when warm and cold, the cold start seems like it isn't even initiating on startup, when the clutch is in when coming to a full stop the revs drop dangerously low to about 400rpm and there's flat spots throughout the rev range oh and not to mention when I turned the air con off today on the way to work it stalled and then when I started the engine I had to keep the engine revs up or else the engine would shake and try and stall...

I'm not going to name the tuner as I wouldn't want to give them a bad name all I know is that they apparently didn't have the software on their laptops to suit the latest style of apexi units so instead they used the latest hand controller that came with the unit.

I'm sure a lot of the problems are tuning related and need to be fix via a tune but I would rather not pay to have something fixed because of poor tuning on their behalf.

Will a tuner fix their mistakes at their own costs or what? Because I'll be damned if I'm paying for them to fix it

Cheers

Any good place will fix their caused issues. Provided they dont blame the car

They can't blame the car everything is running that smooth as anything prior to the ECU going in even had the car checked mechanically and it's running sound so the tuning is the culprit

This really is an issue between you and the tuner.

Do you have confidence in their ability to get it running correctly?

I would discuss it with the tuner and see what they say.

If they are a decent workshop they should correct it free of charge

Sounds like they suck. If they didn't have the correct software they shouldn't have done a half arse tune. I would doubt they would be able to fix it to an acceptable level anyway. like polishing a turd!

Do you have an atmo BOV?

Those things dont sound to hard to fix, but with an atmo Bov, you may still get some stalling off throttle issues. Shouldnt stall when turning air con on or off. There are settings to prevent this.

Otherwise it might be a problem with your AAC/ICV. I think you can check something in SW/SENSOR CHECK on the power FC hand controller (if you have one)

Check the plugs, maybe adjust the base idle as well

Cheers for the input but it's the factory BOV to be honest I cannot stand the whoosh sound and would rather block it off....

I'm not going to mess with anything and will leave it down to the tuner to fix once they have done that I'll be off to see good old matty spry and get a real tune done

[RB_purr]

Oh and 89cal they checked the plugs and they are all good

[Trex]

They gave you the car back running like that? Did they mention anything to you about the car running that way?

When i got my car worked on by my tuner, He got me to drive it and he sat in the passenger seat. Everything was fine and we were both happy.

[RB_purr]

They didn't test drive the vehicle on road but the car was running just fine before it was tuned

The only thing I noticed was the revs dropping very low when I came to a complete stop but it wasn't until the next day when the vehicle was cold that I noticed every little thing shaking and lumpy and hunting idle and then it got really bad one day and kept stalling
