Turbo Rough Idle & Stall

P.S. You boosted a high compression engine, please be safe and don't be hitting boost until you get it to a tuner. This is why I like to have the car dyno tuned right off the bat vs flashing, and waiting a few days for feedback =/

The cars are simliar enough a generic rom can be made but if your having these many issues (likely due to MAP & injectors, as delicious usually uses a different set of injectors) then I would let it mellow out until you get it tuned and avoid driving it. If you had the exact setup that delicious typically uses then the car should run a bit more within the margin of error.

just sent my log again to delicious. and hopefully can get a response soon.

We are working with Toni on this and unfortunately it's never as simple as "It idles on this base map but not on your tune" since the base map is a hybrid and therefore using maf at idle and low load, whereas ours is purely MAP all the time. The fact that there are still fueling issues on the base map as well with extended cranking is suspect, but we're leaning more toward a map issue and are sending a tune scaled for the stock map sensor purely to see if it will idle properly in order to rule out the map sensor.

*UPDATE*

i correctly my rough starting issue. it took multiple cranks to start the car then it acted normal. LJ recommended me to remove my fuel pump and add more o-rings to the pump to seat better. i took his advise and added 2 more even though he said 3 and the car started! with no issues..

Did you leave off the factory pumps o-ring hence the need to add more than 3 o-rings on your new pump?

I transfered oved the factory o-ring and nylon washer on like what the instructions showed.. And had the cranking rough start but added two more for a total of 3 o rings now and the car does start normally now.

Did this also fix your rough low end issue? As far as the RPM's jumping around when taking off or holding them at around 2000

that was corrected via a revised tune that LJ sent me.

I'm awaiting a map sensor from @DeliciousTuning.

they have sent me a tune to determine if my 4 bar from fb was causing the idle flucuation and it was determined to be correct but i am still currently driving with LJ tune which has not given me any issues.. crossing fingers that my flash and go kit from delicious will work with the new map sensor.

Oh alright well I am kind of in the same boat as you were, after 3 months of headaches I finally have my car running without leaks, but the car is idling a little off and is VERY jumpy on the low end, plus it leans out when hitting boost and feels very dangerous to drive, with the base map installed. And I seen you chose to go with Delicious Tuning's flash and go tune and were working with them to fix the issue... is there a reason your not using their tune anymore and are back with FBM's tune??

Ahhhh gotcha, ignore my last post then lol

That's funny because I am also using the 4 bar map sensor purchased from full blown, will have to see if it is also the reason for my issues

Any updates to these issues?

I've been using FBM ecutek tune and 4bar for almost a year now personally. I've had no issues with idle and my failsafe has been spot on with a/f.

I'm saving for a engine build and tune at the same time. I haven't had 1 knock since install either

I do understand I'm not getting the most out of my kit but I rather not bend a rod
