Long story short. 2007 Redline with BW6758 turbo. Ran 2 days at Barber Motorsports track (road course). Car ran great for 5 30 min sessions on Sat. Sunday I was getting a code 0234 overboost code. I...

PMJ, thank you for the info. So I guess we are saying that the "overboost enable RPM" does not work as I have it set @ 10,200. I will be raising the " Allowed overboost error" value.

Thank you,...

I disabled the overboost test and it kept it from posting an error code but it still went into limp mode with no pending DTCs. I took the car of track and did 16 runs to 6,800 with 22 lbs of boost in...

OK , went to the track today. Car ran strong. So strong the clutch is starting to slip in 3rd and 4th gear pulls.

But a new issue showed up. It went into limp mode with an error code of P0234....

I was wondering today what the GMPP tune was set at. That is very interesting. I may lean her out a little more this weekend. Let me get a little more data. My plan is to run a30 min. session as it...

Now you guys are really making me nervous. Hell I was afraid going to 11.9. So just to be clear, you feel 12.6 at WOT on 24lbs of boost at 6K rpms would be safe??

Thank you, Larry.

I have it leaned out now. Runs about 11.9 or so at WOT at 6,000 rpms. After 75 miles plugs looked good. I dropped the WGDC from 90% down to 70%. This dropped the boost to 20 psi. I raised the DAL...

Cobalt, than you for your input. Looks like I got a little work to do. I knew I was running it on the rich side. When I had the Trifecta tune with the stock turbo they were around 11.0 WOT. I...

Cobalt, I reflashed a couple of small changes to the DAL table today and it did not act as previously described. I have attached a copy of my latest tune.

It is running 19lbs of boost at ...

Cobalt, I will see if I can post a tune file tomorrow eve. I'm going to test it a little more tomorrow morning. I have the WGDC at 90% and the DAL table max set at 200. I ran a couple of highway...

If I make changes to the DAL table it seems like it takes a couple of ignition cycles to take effect.

Example, I'm running say 20lbs of boost. Bump the DAL from 195 to 200. 1st run boost goes to...

Thank you T-Man. I don't remember the exact procedure I went thru but the LTFTs are locked at zero so all is good , Appreciate the info on not being able to reset them via the scanner.

Larry

UPDATE: I unhooked the EVAP solenoid and things are looking better now. LTFTs are turned off. I would still like to know why I can't clear them with the scanner if anyone is interested. So now I will...

Mike, I guess at this point it is more about can they be reset with my version (July 2017) of the scanner than actually the need to reset them. I will just feel better if I can reset them on the fly....

OK just tried it again. Car running and logging. Clicked the button and got a screen " Controls and special functions". It came up with 2 folders a general folder with a system folder behind it....

Cobalt, I found and tried that button earlier while scanning and don't believe I got the results you mention. I will try again now and get right back to you. Thanks, larry

Mike, my question at the moment is "How can I reset the LTFTs" Cobalt said I could reset them with the scanner but I don't see how on mine. I watched the school video on the latest version and I...

Cobalt, easier said than done. I looked briefly and did not see a way to clear them. Can you help me out ??

Larry

Thank you for the replies. My car is a 2007 SKY Redline . I did not even know they made an Ion Redline. I now see they did and it was supercharged. Learn something everyday. So if you have...

1. When the battery cable is disconnected are the LTFTS lost ??

2.When we load a new tune are the LTFTs part of the tune ??

3. How many LTFT values are there ??

I working on a 2007 Redline

EDIT: I found a thread from "I Am Broke" and found my answer.



On a recent log my Boost pressure low res peaked in the low 40 PSI. The MAP psi tracked the boost up to 37psi and stayed there as...

I would guess it is tied to the DAL table ??

Larry

Just looked at BW's chart and it looks like you can go 10 full turns which equals 10 mm. Good luck. I will let you know how my "stiff" module works.

Larry

Warning : this is coming from a new guy.

I'm looking at a similar issue. I believe BW makes 3 different WG actuators for that turbo. Do you know which one you have?? I don't believe it will hurt...

Mayhem, what boost sensor are you displaying that shows actual boost pressure ie 22psi. ???? Both of my sensors display the actual boost plus 14.8psi. My car is a 2007 Saturn Redline. I have heard...
