i have my car trifecta tuned, everytime i use the tune i get misfire codes, the engine is up to temp first it will just flash second it will flash continue to misfire and cause it to limp mode even if i get off the gas, does anyone have a fix for this, or dose this happen to everyone?

car has 47k miles bought it used and abused with 26,500. do you realy think plugs would go out that fast account of the history. its been to the shop 6 times since i got it 3 without tune for the same misfire code and the dealer cant find the problem

 

What octane fuel do you use? lol

 

Shouldnt be it, I run 91 oct with no problems. Id say its plug gap?

 

Go hptuned.......... change plugs get stockers.

 

did you datalog and send the logs to vince or are u just running the canned tune?

 

i have same tune. run 93 octane no problems

 

^^^^ u r also not a lnf only run 93 but if u can't get 93 grt 92

 

ok first off its what ever V-power is, havent checked plugs, i cant data log since computer i had progam on crashed and i dont have a cable. HPtunes was thinking of going and getting GMS 1 just to get rid of the problem

 

V-Power is 93 octane so your good in that area, I would change plugs though cause I'm sure thats whats causing the misfires

 

^^^^^^if u didn't data log then,bam,there's ure problem. Second hptuners is easy with lnfs. ........ find a person with,hptuners that can tune lnfs.

 

ive liked the trifecta so far its not like i use it all the time just wanted that extra power for messing with faster cars. car has 47k miles bought it used and abused with 26,500. do you realy think plugs would go out that fast account of the history. its been to the shop 6 times since i got it 3 without tune for the same misfire code and the dealer cant find the problem

it would be nice man but im broke and trying to get by with what i have

 

To be fair, every time I have seen you driving you have been beating on the car. Just saying. With that said I would suggest at the least taking the plugs out and re-gaping them if need be.

 

yea maby once in a blue moon. like 2k miles of abuse. trust me ive stoped that. ill see if i got time tomarrow at work to check them its always in number 3.

 

I feel as a tuner. Depending on abuse u put on the car. Depends on the changing of the plugs. so if u abuse it change them every 15k miles .

 

U could also have. Bad coil....,change the coils,number them so,u,don't get confused.....

 

know of any better than the stocks? always looking to upgrade anything i can

 

o know that, i work at a ford dealer. lol oil change tech tho i hate mech work

 

the tune not being dialed in is probably your biggest issue since you say it only misfires when the tune is activated. however the plugs could be it too. you need to datalog and email vince, or just go with a diffrent tune like everyone else on here is saying.

 

Lol I used to be a diag ,toyota tech lol I have my assosiates in automotive engineering. Ans had 5 ase'

 

UTI grad for collison repair had all the I-car certs till last year cant seem to find a shop to work at.

well ill update tomarrow on this see if thats the issue. what should they be gapped at since the dealer hates me thats open and wont tell me

 

i had an issue with it not boosting properly when i fist installed it. that has stopped now this bugs me, only happens in the NLS between 2nd and 3rd

 

i wouldnt recommend NLS on the tune anymore

the initial tune that vince sends is just a canned tune. your supposed to datalog it and email vince the logs. then he sends you a refined tune, and you keep repeating till the tune is fully dialed in for your car.

running the canned tune isnt very good for your car, however the canned tune vince sends is on the safe side. anyway, take everyones advice and get a retune and spark plugs. even tho im pretty confident its just your tune.

 

ok i guess ill buy that guys cable and contact vince, when i got the tune no one told me about that, i thought i just plugged in reflashed and went on my way.

 

now you guys got me all worried about going Trifecta.

 

dont be im just engine illliterate as like many other things.
