Here is 2 PL files and the slips for them. Pass 2 was 23/19 timing and Pass 3 25/20 boost about 24-25lb. The last pass (11.85) my laptop battery was dead. I opened my dump and ran 26/19 timing. I ended up with boost creep on that pass up to about 28lb at top of track. I thought after cutting off my Flowmaster and installing a Dynomax Ultra flo it wouldnt creep that bad with dump open (wrong). I saw the Kr on my Scanmaster before the traps. I still need to get it dialed in better. No more kamikaze passes without the PL! The 26 degrees of 1/2 timing on my last pass really woke up my 1/8 mile on the high 11 pass. The track was dead hooking with the prep. Also I still sometimes log knock on my trans shifts which I assume is false.

Put the car on the dyno thursday and tried to dial it in better. Put it on the track friday night. Finally broke into the 11s. Had a few 12.1x passes first with fairly soft launches. Its still a work in progress, having some boost creep issues on the big end that is causing some knock. Actually lifted a bit before the trap on the 11.85 pass saw some Kr on Scanmaster. More tuning required but closer and Im getting the hang of tuning the car. IDC at 75% with the e85 and 80lb injectors!

Thank you guys. I guess I will work on it at the track on the 25th and see what way to go. It will be a prep night so my car should hook much better that night.

Here is my highest boost log. I have been seeing 1/2 shift knock occasionally even when I was running 110 fuel. This particular log was on street and was spinning tires bad through 1st gear and I peddled it once. I also have a question about the 02s as they are down 750ish at end of run but my WB reading was still rich around 10.8. Is that bad, does it need more fuel even though afr is ok? This is my first time being able to see the O2s and the wideband reading together as before I had no idea what my afr was.

Its hard for me to be able to go make pulls like this on the street around here, so I dont plan on hitting this top speed again until at the track. The knock at the shift kinda bothers me also, sometimes I get it and other times nothing. Any guidance is always appreciated! thanks

And I forgot to put my fuel psi gauge back on wiper before I went out early saturday. I checked pressure to boost rise through second gear earlier in week but not top of third gear.

Thanks Steve, working with the wideband is new for me so I am trying to start on the "safe" side. It seems the 80s will be enough injector for now.

The 10.8 is the default correction setting Eric set my new 6.1 chip at. I can change it for 1/2 gear and 3/4 gear. Im going to try and lean it out some and work on the timing now that its running well. The chip works well at holding the set AFR.

Got the car running on e85. Worked my boost up to 25lb and my wideband correction in my TT 6.1 chip is set at 10.8. The IDC was 80-85% at that boost level. Hard to believe $3.47gal fuel can run like that! Hitting the track April 25th to dial in and see what it can do.

Thanks. I remember putting the online site in my iPhone search maybe a month ago so I could find it again. I remember pricing was good but of course I cleared my search history  . I dont remember what post it was in. I have read back through some.

I remember seeing mention of where to buy a fuel psi sending unit to log fuel psi on Powerlogger in another post. Steve Wood was that link from you? Thanks in advance. Im tired of zip tied gauge on my wiper to check pressure under boost.

Scoobum are you going away from the Hoosier drag radials? I remember you mention in the past you were using a set. What range of air psi did you run those at?

I just bought the 80lb inj to replace my 60s. They are the biggest a stock ecm can run without being modded I believe. My goal is high 11s so they should be good. I will post some PL logs when the car is back running to see the inj duty cycles. Very curious to see how it compares to the 110 fuel.

I have had several local Turbo Buick guys here convince me to try e85. They have been running it successfully for many years. I have a new e85 friendly fuel pump, 80lb injectors, AEM wideband. The new TT 6.1 chip is in the mail. Hopefully will be running by end of next week.  Buying the 110 fuel and O2 sensors has gotten old fairly quickly. Anybody here have their car running on e85? We are having a Buick "event" at the 4-25 test n tune so I will see how this car does on the new fuel.

IHADAV8 Playground / Turbo Buick variety

Went to Cars & Coffee this morning. Small Turbo Buick showing but wide variety! We had a TTA, hot air T, 64-65? Buick with GN drivetrain and my 87 GN. Disregard my finger in the corner of pic, would think by now I could take a good picture.
