engine isnt making factory boost level

[DarkLight]

its most likely a spike

True, but the gauge doesn't appear to reflect exactly what the logs are reading at. All the logs show sustained boost in the 12-14 psi range at WOT. I'd be running an analog boost gauge if I had a 1.5.

It should definitely be making more power with the lower knock values, so that kind of stumps me since yours is pretty much optimal. Additionally, ignition appears very conservative 4-8* BTDC max sustained. So definitely not knock.

Also, your injection duty cycle only maxed out at 30%! I am very surprised by that. That means you've got room for a much bigger turbo on this motor.

ETA: After reviewing all of your logs, it seems the ECU is partially closing the throttle plate as the CVT changes it's ratios and that is causing a dip in boost, which takes some time for the turbo to regain. That is probably to prevent a torque spike from causing damage.

I find the boost drops every time it fakes an upshift and then gets back to max boost as it nears redline again.

yea that was the first thing i notice about the injector duty.

We might have the same problem, I think i seen my do that sometime. I seen it only boost half the meter only on some occasion like that

what if you use L,.....wonder if the psi will stay pegged at max?

it doesnt

 

[kmccall1978]

it doesnt

So what we really have here is room for improvement, which is great.

My car was never making 14 on the factory tune. it was peaking around 11 or 12

As for the car getting worse after a little driving, but performing better right after a reset or flash. that issue has been worked out by ktuner for me!

Apparently my car doesn't like 93. Switch back to 87 everything is back to normal. Going to try 89 next

I'm on 91. why didn't it like the higher octane?

 

[dc2turbo]

not sure , knock control is taking over. It might not be mapped correctly for it

 

[kshawn]

Are you running a higher octane tune? the factory map is tuned for regular, that could be why the ECU is angry.

 

[LTurbo2016]

just brake boost you'll get 100% boost.

 

[kshawn]

Cvt might not like that but I'll give it a shot lol

 

[LTurbo2016]

ive done it to my CVT EX-T it worked but yeah make sure your car is warm lol. but apparently on the newer turbo Acura's full boost through the "gear" you are in and the next by brake boosting
