I'm making a separate tune for the winter which is power restrictive and fuel efficient. When I have the power available, I end up using it. lol, the boost is waaaaaay to addictive. It's only for...

hmmm, I don't have the injector flow rate PID.

I don't think that would fly since fuel pressure plays a roll in that as well I would think.

What about VE Airlfow / AFR plotted on engine load and RPM?

I made a tune for the winter to get max gas mileage running on regular gas. Anyways, I'm at the point where I'm fine tuning but need a good way to see if I'm actually making gains for mileage or...

Should the AFR spark correction be all set to 0 for the LNF when tuned?

Did the flutter stop or did the code just go away? I'm having the same issue and I've played with the BOV surge limit but it doesn't seem to fix it. I never started tuning before GMS1...Can someone...

Just a thought...but wouldn't pulling back intake and maximizing overlap give you the best mileage? (maximizing cold air going to turbo and closing intake valve before BDDC). At first the ECU would...

Trying to figure that out actually. I was going to email you to ask how that would work. If it's getting stuck closed sometimes I would want to lower the ratio of the upper surge limit? Not overly...

Has anybody tried valve timing smoothing similar to the spark timing smoothing?

That's exactly it, the BPV isn't opening and it causes surging.

I sent you an email with tune and scan.

Thanks!


Just want to add that the scan was done during a drive when I didn't have the surge. I'm sure I can scan it sometime when it is surging if...

I been tuning with purge solenoid unplugged and my fuel trims are within 3 or 4. My PE Lamda is 1 or less everywhere. What could cause it to go rich during shifts?

I'm gonna do this too. Dropped my car off for a tire balance/rotation. They put on 25km and my average fuel economy was 12.7L/100km and I drove it for 30km lightly before dropping it off. It was...

I know everyone's going to jump to saying "it's the stock BPV, get the forged BPV" when I post this but I'm debating whether that's really the case (even though I ordered it. LOL)

Anyways, I'm...

How are you guys measuring the 60-100 time? say start at 50 and have full boost by the time u reach 60 or 60 and pin it? i think that's why there's such a huge gap between the red's time.

i ran...

What does the optimum spark table in the torque management tab do?

Does that apply for 2.0 LNF?

Anybody know what the limits of the of the cam shaft timing is before u start hitting the piston or other valve?

You can make a PID that measures the Manifold pressure and subtract barometric pressure

([SENS.30.MET] - [PID.2340.MET]) / 6.894757

I've logged twice now for about 30 mins each time since taking the BPV apart to check the diaphragm and haven't seen any knock and I haven't changed the tune either. Not sure if the diaphragm was...

I finally got the chance to take it apart. Looks like new, didn't see any tears or cracks or anything of the sort. The mount of KR I'm seeing is <2.5 but it's in the mid range so I'm trying to...

Sorry guys, should have mentioned I got an LNF.

And to the comment of instead of doing your research, just have someone do it for you, there is tons of different methods that people are putting...

Can someone make a good E85 tuning guide showing the whole process (running half tank of e85 to start, which histograms to set up that are different than what you would monitor for 93 octane, etc...)...

I'm fairly new to the whole tuning this but as I'm data logging, I notice I'm getting KR when I let off the gas. I have the purge solenoid disconnected. Any thoughts? Is this real knock or is the...

I'm fairly new to all this and I know this is what they had to do on LSJ to get it dialed in but is this the right way to go about it for the LNF? Is there a better way to get clean results?
