Did a full pull wot through 2nd and 3rd gear for the first time. Temp was about 51 degrees on street tires so I rolled into it in 2nd gear and seemed to get a little wheel spin after the 2-3 shift. I'm pretty happy with the way it pulled and motor sounded good. Log looks pretty safely tuned to me, but I'd like to get some more experienced tuners input. This setup is the first one I've tuned, but put a lot of work into idle and part throttle tuning prior to this as well as several 2nd gear pulls.

Setup is cam only sbe ls1 with d1x procharger. Fuel pump is dw300c and daetschwerks 60 lb/hr injectors. Plugs are tr6 gapped to 0.030 pump 93 octane fuel.

 

Can't open the link you have posted. I tried saving link and then attempted to open it in my scanner and still could not get it to open.

 

I couldn't download it either.

 

the site no longer supports tune file extensions. you'll have to email then direct or upload them to a cloud type storage with public access

 

Thanks for the info. That explains why I couldn't figure it out. I did get the attachment to work on the hptuners forum.

Originally I was seeing 10 pounds of boost shifting at 6550ish rpm. It's now shifting at 6200ish and seeing 8 pounds of boost. I was getting up around 95% injector duty cycle at 10 pounds and now about 87% at 8 pounds so I feel better with that.

My afr looks good all the way up in the high 10's low 11's. I'm getting a little hesitation between 5000 and 5500 rpm in 3rd gear only. During the run it was barely noticeable no popping or misfiring type of sounds. Car sounded good the entire run and pulled good all through 2nd and above 5500 rpm in 3rd.

This seems like an area that typically gives ls valve float issues. My springs are 660 lift btr with less than 2000 miles on them. Most of that was cam only and maybe a couple hundred miles with the procharger now. This was my first run all the way through 3rd gear as I was working on the tune previously and started having trouble with the stock trans. I plan to raise the 3rd gear shift point a little more up to the 6200 rpm range like the 2-3 shift now that I know the afr is good.

I ordered new plugs and plug wires and will try a slightly smaller plug gap like 0.026. I also ordered some dielectric grease because I haven't been using any. It looks like my plugs are actually gapped at 0.032 now.

The little "hesitation" between 5000 and 5500 in 3rd was barely noticeable during the pull, but I was watching a lot of things. I even had to avoid a huge bird that was eating a dead animal on the side of the road or I would have stayed in it a bit longer.

If anyone wants to take a look at my log you can either check it in the gen 3 section of hptuners forum or pm me your email and I can send it to you that way.

ETA: actually after reviewing the log again it looks like it does do it in 2nd gear very slightly as well in the same rpm range.

 

i'd say spark blowout before spring float. i run singles up to 7500 rpm and havent floated

 

 

OT but that makes sense in my other thread I posted and uploaded my tune and log.

 

10-12 degrees of advance at WOT seems low. You have zero kr so might trying bumping up some and see if you get more power.

 

 

That would depend on the boost. It is a stock CR on pump.

OP if you're running more than 5-6 psi I'd go to a TR7 nonprojected plug.

 

 

 

I didn't have any problem opening your file with 3.7 beta. Maybe why others can't???

I had to use Boostane to eliminate kr in mine. With Boostane I was able to increase advance 4 degrees and with more testing maybe even more. I logged kr even when my car stock and with 93 octane. Supercharged cars like good fuel and high octane.

 

 

I'm running 7 ounces to 5 gallons.

Here's a screen shot of one of my log. Running up to 25* of advance but only 11 psi of boost. Mine is Direct Injection but I bet with Boostane you can run more too.
