TSP stage 1 mileage

[alxgravel]

It's probably the intake and not the plugs. Is this a street or race? One way to find out what is causing the issue is put the stock intake back on and see if knock goes back to 0.49 and if the rich idle condition goes away. If you are not throwing any codes you should be fine

I reflashed to stock tune to look those STFB1 and was the same thing happening... So tomorow getting new spark plug and we will see.

I'm on stock maf ... 27won race maf still not availble . My knock is stable always at 0.49 and sometimes on hard driving hitting .52 thx god for the petro-canada 94 oct.

Today did a 2 hours ride and nothing poped out .

This poped out on 5 mins on idle my friend works at honda and he tell me when ur getting -20 or more for 3 mins the oxygene sensor will pop-up he changed his spark plug 2 times already on his sport hatch with a tune... But its only happening on idle ... The car is pretty good when I pull wot and riding. I remaked if the ac his on idle ... The STFB1 his better

Well my business partner have an 2018 hatch sport we did all the same tuning setup and he have not issue with nothing his STFB1 its pretty stable like -6 on idle and wot 0 . He have like 10k less then me so maybe his spark plug working pretty well.

Honestly I don't know how your able to get it that low. Mine stays on 26.8 and I am often a dick on the road. About 37 on long trips with 80 on the cruise control. You must stay on the pedal!

Same numbers here, but I'm on Ktuner's 19.5/21 tune.

Changed plug.... Its day and night my spark plugs was maybe dead ... I looked those stock gap.. 2 was 32 and 1 30 and the other I killed it so didnt look. I gaped all the new one with 0.28 gap and the car look fine. More throttle responds and stfbt1 his very more stable!

Hi Guys! Im new to the forum, though I've been looking plenty of things up. I was really hoping someone could help me out. I just bought a 2017 civic si coupe and installed the tsp stage one tune. I just figured out how to show mpg lol and im getting in the low 20's. I was running map 2 in sport mode, but even when I turn it down to map one without sport im getting in the low 20's to maybe 27 at the most. Any idea of whats going on =( I need help

I’m thinking about getting the tsp stage 1 tune and read that premium gas is required for this tune, what gas is everyone using ???

With a tune, always use the highest octane top tier gas available, if you can. I use 93 octane Sunoco Ultra.
