    Trifecta problem please help

    I was wondering if you could help me with a problem. Ever since I tuned my cruze it is awesome but is throwing a P0300 engine misfire code on 3 occations I have had a problem with the tc and esc failure and service. Today while on dyno did one pull in 3rd and the car started smoking from the exaust. I always had the tc and esc problem as well as the misfire from the tune but last night I got gas from a diff station than normal and the car started acting a little funny Vince looked at my logs and said its the car not his tune and the tc and esc problem is because a faulty system but Jerry at BNR said that's a tune related issue. I also had the local well known performance shop by me look over my data log the guy does awesome work with Subaru and I trust him said with the dyno results and log my afr is all out of wak but Vince says no... He says to just regal my plugs to .28 but I haven't touched it and says none of my problems are tune related although they only started when I put the tune in

    Check your plugs. There is a small chance they are among the few plugs gapped over 0.028" from the factory.

    Yeah, check your plugs!! I can't run any bigger gap than .028 or I get spark blowout on the trifecta tune!! Started at .035 and worked my way back to .028 thats when there was no trace of spark blowout!! Hope it works for you!!

    Its like a miss in the upper rev range under a bit of load (i.e. going up hill in third gear with you foot flat to the floor and as you reach around 4500 rpm starts to miss and carry on). I'm sure someone on this forum can explain it better than me!! lol

    Misfires can cause issues with traction control when the wheels stop spinning as fast but the computer thinks they should still be spinning just as fast. So it kicks on the traction control to keep them spinning, or so it is programmed.

    Agreed, check your spark plugs for the gap width, and make them all 0.028" gap width. Consistency is key, and the factory plugs are not consistent in their gap.

    Try flashing back to stock and see if the problem goes away. Also, can you post up a datalog so we can see what's happening? Assuming you have a cable...

    I had Vince look at it and they guy from my shop the data log Vince said it is fine my guy says to lean in low rpm and too rich in high rpm... I think the white is oil burning off because they said they had to add a quart of oil... As far as flashing back to stock how do I do that I watched the video don't understand do I just choose the stock tune option

    Yes, choose the stock tune option and re-flash.

    If you're a quart of oil low, there's a mechanical reason for that. Find out what's causing the oil loss, fix it, and re-flash the tune. If the engine's burning oil in addition to fuel, that will throw off the air-fuel ratio and cause the car to run poorly. If enough oil is burned it will foul spark plugs, and cause a misfire.

    Don't worry about the tune for right now. Find out why you're losing oil and fix it. Replace the spark plugs when you're done, too. It sounds like they might be fouled.
