  1. Need help with adjusting fuel trim without breaking anything

    So far out of all the tunes I have at my disposal the map stg 1 map 2 has been the best at alleviating the problem, what's weird is my fuel economy is actually pretty decent, 27 mpg on average
  2. Need help with adjusting fuel trim without breaking anything

    Ok dope, I'll order one right now. Thank you both gents I see you guys constantly commenting on newbs posts. Very relieving to know you two are out there doing God's work helping us newbs not break our dope cars.
  3. Need help with adjusting fuel trim without breaking anything

    Absolutely correct, I did buy this car used and it's modded out the ass. When you say replace the intake, my current plan was to replace the down pipe with a prl catted dp. My mechanic said that that would fix the problem. Do you think it would have as much of an effect as replacing the...
  4. Need help with adjusting fuel trim without breaking anything

    P.s. I am running 93 octane shell premium v nitro with Lucas injector cleaner additive, on MAP stage 1 map 2(which is helping a little bit) stft is jumping as high as 45% but ltft seems to stay around 3%-6%
  5. Need help with adjusting fuel trim without breaking anything

    Too make a long story short, I thought I had a vac leak, took it to 2 different mechanics, both said everything is 100 but that I have way to much airflow to be running my car with no professional tune. Here's the catch, I was also informed that I have a catless down pipe, which I would prefer...
  6. Im the big dumb

    I do have a injen evo 1500 I believe and my trims were at 14%long term and between 0- and 45% short term. Since I have had the tune my long term has stabilized and my short term is much less erratic. I'm currently running MAP stg 1 map 2 and having very few issues. Now another new question, if I...
  7. Im the big dumb

    Recently been having some really strange readings on my 10th gen si with regards to fuel trims. Thought I had a vacuum leak or a messed up ewg or egr valve or whatever could cause lean fuel trims. Turns out I have too much airflow because the previous owner went catless and my stock tune...
  8. Bum injectors or?

    p.s. I think I posted the same pictures twice on accident but they are from the same instance
  9. Bum injectors or?

    I have recently purchased my si and am in the process of trying to get it back to tip top shape seeing as the previous owner was not shy of the pedal. I got the ktuner to eventually put a tune but in the mean time I am using it to monitor and learn. As you can see in the pictures there was 2...
  10. Official TONIC YELLOW PEARL Civic Thread

    I'm new to cars in general, sold my sorento with 150000 miles for the sport and had HEAVy buyers remorse with the cvt lag so I bit the bullet for the si. Done a lot of research in the past 2 months but I still don't know as much as I would like to. The exhaust is stock (according to my mechanic)...
  11. Official TONIC YELLOW PEARL Civic Thread

    I just got back from Georgia after 28 hours of driving in shifts, first thing I did was drop it at firestone so I'll have to get back to you on those pictures. I know it is modded, there is a injen evo1501 on it at the very least. My guy told me he'd let me know about the exhaust when he takes...

    I traded the TYP sport for a TYP si, and now im trying to find the person who had it before me. When I went to buy it the dealer didn't have any mods listed so I went into it thinking it was stock. BOY WAS I WRONG, THIS THING FUCKING RIPS. I just need to find out what all they did to it but I...
  13. What did you do to your Civic today? (II)

    I traded my 19 civic sport with k20c2 and Cvt Trans for the 19 civic si manuél. Don't get the cvt if you want to mod or tune at all.
