Did you look at the intake shootout data from Drift office, they like most other tuners are measuring stock 2012-2016 cars down in low 11 or high 10 as per OL fuel table. The intakes that produce the power increases are also the one that leans the afr the most. Ive no explanation why those guys are different to everyone else

What sensor though? The stock one, or an aftermarket one? If it's the stock one, did the re-scale the O2 so it'll read that low?

[nikitopo]

A high precision aftermarket sensor.

Im really surprised by the number you are getting, I just got my 86 on the dyno today at Lachute Performance.

I have the gruppe s headers and overpipe, invidia catless resonated front pipe, invidia n1, grimmspeed intake, ecutek tune, whiteline diff, trany and rear subframe bushings.

Results : 212hp/159tq .. 166whp

This was done on their dyno which is a MAHA lps 3000pkw i believe.

I always fill with shell 91 vpower but i had a badluck and had to fill with ultramar 91, the tuner ask me if i had put in normal gas in it because he couldnt get higher numbers..

After i picked up the car for a drive back home (8h drive btw) the car was feeling slower than before i got the tune and the gas pedal was very not accurate.

After 300km gas pedal came back to normal and i felt there was A LOT more power then when i picked up the car from the dyno.

The power band now is very very linear and the power is better than before i got the tune now that i drove it over 500km. My butt dyno feels like my car is doing a lot more than 166whp and that i am closer to 175_180whp.. bht thats just my butt.

Also torque dip completely gone

If i get the chance ill try to do a run on a another dyno

So i did some researsh on the 86 quebec forum and seems like everyone who been on their dyno did lower numbers than what we see on this forum. There is a sheet with results of members who did run on Lachutes dyno, after seing this, i think my numbers are not too bad after all.

[StraightOuttaCanadaEh]

It's crazy how much power is lost between the engine and the wheels. Almost 40 hp. Is there a way to minimize that loss? How do you increase efficiency in that regard? Or is it just the innate characteristic of this engine

There's lots of ways to cheat on a dyno or to just scre up the results. Lots of places are run by monkeys and many just don't calibrate often enough. The results of that shop's dyno are abnormal compared to every other non-boosted 86 on the planet. I suspect the dyno operator is the reason the results are so far above norm. I have no proof but I can tell you- those numbers ain't right.

It's every car. There's loss in the drivetrain and you can minimize it somewhat by stiffening the driveline and tranny but at the expense of NVH and reduced lifespan and increased wear and tear of components. But the gains are so small you just have to suck up the loss.

If you look above your post i did post a sheet with people who been on there dyno and did very similar numbers to mine, my guess is that this kind of dyno reads a lot lower than other dyno. Lachute performance is a very reputable shop in canada they did a lot of frs/86/brz as well as a lot of subies.

I have done extensive testing with my tuner and cannot see to get them to work. Map switching via the cruise control stalk is also not working, we had to go back to the old style map switching, which works (gas pedal + defrost button).

Racerom features works great with my 2017 86 and i do switch the map with the cruise control. Your tuner should ask help from ecutek because from what my tuner says its a little bit more work to make it work on the 17's but ecutek can help you out.

This is why you get a stock dyno before mods, on the same dyno. Then you know what you gain from the mods. Just looking at post upgrade numbers is kind of pointless IMO, because every dyno on any given day is different than the next.

Doesn't that make Dyno results pretty much useless, even if using the same dyno?

Ambient changes are so minimal, so not really as far as I'm concerned. Going to a dynojet then to a mustang dyno are going to look a lot different on the other hand.

I live 8hours away from the closest dyno, so 16 hours to go amd comeback. Not to me tion the road to get there is full of potholes and bumps.

I just wanted to get my car dynoed so it run better with the mods and to get rid of the torque dip and have a linear power band, so for me getting a dyno when i was stock would have been a waste of money and time. To each theire own
