94 octane not pulling
 

I've realized that my car doesn't pull at 4th or 5th gear, could it be because i have 57 trim? It just makes a lot of noise but doesn't pull hard like let's say 3rd gear
I'm still learning to be nice :P

Could be as simple as 4th gear just doesn't pull as hard, or something else like a boost leak so the turbo is "working" way too hard

Is this a new development, or has the car always behaved like this

It's cause you are Canadian. Have you datalogged it? Do you have any way of monitoring your boost and AFR during these pulls?

The 94 we have here in Canada is actually really good. I have experience with Husky only and i never see knock in my logs.

What RPM are you starting from? If you are starting from 2000rpm you are just going to be creating a whole bunch of load and yes it wont go anywhere for a while.

Now if you are starting at 4000 rpm in 4th you should be moving pretty quick in no time.

I have a AFR/Boost monitor .. Boost hits up to 9~psi which i think is too high because I should be hitting 7 MAX .. AFR is around 12.8~

I don't know i don't really do a lot of dyno pulls. I checked for any boost leaks and everything seems to be fine.

Starting at about 4500RPM and stomping the gas it doesn't go far. it's weird, It could of always been like that. I did a virtual dyno and it says i have 291HP 225 TQ .. I just realized now on the high way that after 3rd gear and slam it to 4th it doesn't go far lol. It was just a random question wanted to see if anyone else experienced it

I"m thinking it's probably my lack of injectors/fuel pump

You've got to post some kind of data log or dyno sheet.

94 here is awesome, use chevron if you can it is the only one without ethanol (atleast in BC)

That would effect every gear, your tuning doesn't change based on the gear your in, unless you have an EBC, then it's an option.

My only guess is that you are pulling more boost in 4th gear and hitting a boost cut that was put in your tune.

This help?

Holy shit lean.

Thats what I'm saying...

You need to contact your tuner, and get it to a dyno or street tune. That's unsat.

That's Toni@Fa20club

I sent him a datalog nothing yet..

Is this the can tune? If it is Toni, make sure you keep sending data logs, even when your happy with the tune, he will get this sorted out.

Yeah the e-tunes. It also doesn't help I dont have an intake tube :/ :iono: :mad0259:

Maybe want to call fa20club, he could be sick or on vacation, that looks like he wasn't quite done fixing you yet before u dyno'd it.

When you say you don't have an intake tube, can you explain?

I meant the pipe, from the turbo.
Check my build thread look at my intake, it's connect straight on the turbo.

I thought the issue was 3rd gear felt good and 4th gear didn't. Can you post more than a Virtual Dyno?

Ever since I put the 3" turbo back i've had this prob, I'm putting the new fuel pump next summer along with injectors. I called Toni he said hes gonna check the datalog

Want me to post my datalog?

If Toni is looking at it you should be good. Your AFR definitely should not increase like it starts to at 5200 RPM which could be a fuel pressure issue due to the pump or could be the tune. I still don't see any of this making a difference depending on what gear you are in.

Could it also be that My intake is on the turbo and not attached to the intake pipe? Thats why I run lean?

Shouldn't make any difference.

Here is a video of a turbo frs in 4th at 4k rpms. Don't know if this helps.

[ame="https://www.youtube.com/watch?v=BvQH0pYrmJM"]Frs Turbo EFR 7064 4th Gear pull at 60mph. - YouTube[/ame]

I'll do a pull from 4th gear at 60mph as well to compare, your rpm seems to go through faster

Hey don't get on it until u get the problem fixed. If something don't feel right, don't chance it.

I second this motion.

So i've got a response from Toni, and its not within the Tune, it's because I don't have my injectors or fuel pump. So i'll order it next year. But problem is, I hope there is no damage as i've already done 2 drift sessions and tons of 1/4 miles. Grrrrrr...

Which trim kit do you have and how much boost are you running?

Last I checked, unless he sold it, @Sportsguy83 was selling a good combo of fuel injectors and fuel pump.

And yes, you're causing damage if you're starving the motor of fuel. Boost with a lack of fuel can be quite catastrophic.

With the 57 trim 7 psi is the max for the stock fuel pump and injectors, not sure which is the bottleneck so I said both. As a safety precaution and to give a bit more of a safety buffer, I err on the side of upgrading the injectors and pump when boosting it.

He sold them already and got paid in $1 bills.

I got the 57 trim, on my boost gauge i boost peak at 8-9 PSi.

I'll be buying fuel injectors and pump soon. Just waiting for my UEL headers to come in! been a month already :/

Yeah outside of the range for stock fueling. If you insist on boosting, safely, I would dial the boost back to 5-6psi and wait for the injectors and pump, along with a tune adjustment, before cranking it back up.

i dont know why its boosting that high.. I dont have a mbc or ebc..

Well that's another issue. Have you changed the the 5psi base pressure spring?

You're doing some over boosting there. Without some boost controller that spring should max around 5.4psi.

It was the yellow spring for waste gate right?

This, larger exhasut on a turbo car = less backpressure in the turbine and exhaust manifold section = more boost. Your boost went up when you installed this exhaust. Your tracking load ranges that were probably not tuned and you are probably beyond the fueling capacity now, or some combination of those two things. Also, if you are using an MBC or just spring pressure, you will make more boost in the higher gears. You need to get the boost back to were you were tuned or where the stock fuel system can keep up. If you need to turn the boost down, get a softer spring for your wastegate, and an mbc if you don't already have one.

So basically to be properly set up I need the following:
- injectors
- Fuel pump
- EBC or MBC
and of course a retune
