60-100 4.07 seconds

I at least took the log on a kinda warm day to be fair lol. It was 44-45 outside and sunny

So did you blank out that big ole hairy .74 lambda spike when you hit WOT?

I got mine to about .8 on tip in now, but that's about the best I could get.

LTFT's still wander from -1.6 to +1.6 in traffic, but it settles in at -0.8 most days, which is where I like it.

I never get a time like that though. Maybe after the clutch is in. Congrats!

Nick, If you want my MAF & Correction tables for the Hahn CAI as a starting point, let me know. I'll send them tonight.

[BackyardTurbo_FTW]

.8ish on the spike usually. After a long drive then an update its running really smooth and the trims are spot on. Ill post a screenshot with ALL of the info once I have it just right I know Term is fanatical about trims so I dont even want to post them til they are just right LMAO!

[Iam Broke]

P.S. Looks like you need a clutch again.

[BackyardTurbo_FTW]

Clutch is solid, thats wheelspin Car likes to break loose up to about 90 now lol

[Iam Broke]

The Hahn CAI is very finiky on the trims, you'll get them spot on for a few days then they'll change a few points in the ~4000 hz range due to the turbulence I guess. It's a b!tch to dial in. At least it was for me, but once you get it there, it runs the best of any intake I've tried.

IIRC, I had to taper the main MAF freq table like an S curve to get it close. Lots of positive trim in the Correction table in the 1000-1700 rpm, 40 - 70% load areas for stop & go traffic. I had a lot of issues with the LTFT going to +5 in stop & go.

Wished that they would come out with a CAI for the HHR

Still though 4.7 seconds from 60-100 with a tune only and 4.0 seconds without a pill is not happening where I live.

[Iam Broke]

I can get it if I run downhill...I'm just sayin'....

[Gimpster]

Hah... our next benchmark will be 60-100 runs on interstate entrance ramps

[BackyardTurbo_FTW]

360+whp without the pill mod isn't happening where I live, so we're even

[BackyardTurbo_FTW]

Then by all means, do it and post it, I'd like to see it...

LOL you just have to find a happier dyno.

[BackyardTurbo_FTW]

^Working on it

BYT and I have had great conversations through PM. Anyone that gets upset about him not posting his entire tune needs to either figure out how he got the numbers himself or move on. I've hit 6.1 60-100 with .87 lambda and all stock parts. I could see if the car was opened up on the top end the 4.5 could be achievable. Question about the tune though...is it 22psi consistent or a spike?

[BackyardTurbo_FTW]

It's a short hold of 22, I wouldnt call it a spike but I wouldnt say it's consistent either. Ive found letting the boost trail off a bit at the top like it wants to has net some nice results Currently .88 lambda with a peak of 19*.

[GeoffH]

hmm, short hold of 22 psi? Seems like you would have more than that. I spike to about 28 in 3rd and then hold about 25 then tapering off to about 22-23 at redline.

of course thats on the boost gauge in the car.

[Iam Broke]

I don't think BYT is running the pill mod anymore. Mine boosted about the same as his without it.

.035 pill and my DAL tables will boost 24 - 26 psi depending on load/gear. Tapers off to 18 psi @7200 rpm.

[GeoffH]

I have no pill mod either, just shortened the rod length on the turbo.

[schaid]

I actually see a slight increase as I run through the gears, mostly on initial upshift, like going from 2-3 I'll see spike to 22 then settle back out to 20 nearly instantly and the same for 3-4. I don't have the trail off like you guys are talking about. I only run out to about 6500rpms due to my knowledge of all of the previous ecotecs GM has put out. They all tend to get a little pissed off about 6800 due to the balance shafts. I'm not sure if GM has changed the balance shafts in the LNF, but I know in the L61, LE5, and even the LSJ, if you are looking to rev high, the balance shaft thing needs to be addressed.
