3000rpm up my driveway, and my neighbors will love me:laugh:
It just takes a little more gas to get up steeper grades, and I also think my warm idle tuning may not be as good as it can be.

Thanks, and I didn't think my cam was that aggressive.
That cam screams in the 3100lb 944, and I'm ok with the choppy idle and slight surging if that's due to the cam profile. The car has a 3.778...
No problem, see my response inline.
Is intake air temp (IAT) getting hotter than ambient...? IATs average around 67F, very close to ambient. I have relocated the IAT to beside the air filter.

I have been battling an issue with my LS6 swapped Porsche 944. When the car is started from the cold, it runs fantastic with lots of power. When the car is shut off and sits for a while and...
Thank you, and you bring up a good point!! For a while, I have suspected some weird electrical issue that could affect O2 voltages because I get random O2 codes. I will take a look at the alternator...
I got the car out for a good run, and here is the log file and tune. The first thing that I noticed is the -STFT which indicates the car is running rich. I do hear a lot of exhaust popping that...
Sounds good. It will take me a couple of days, but I will get the log.
Yes, both banks are set to 450.
I have an LS6 swapped Porsche 944, and I failed SMOG by nine points at 15mph HC. I did some logging based on posts I have read on the forum, but OS2s are switching, and I see LTFTs as high as 10%. I...
This is going to be a tough one, but here I go.
I have an LS6 in a Porsche 944 and want to install a CAN Bus data logger. I know GM did not provide CAN Bus on its PCM's till 2006, and I'm trying...
Got it, makes sense why my VET was so far off. I previously stated my EQR 1.75 but I entered EQR 1.175.
Yes, I type in 1.175 and 1.180 is displayed. If I copy the contents of the cell and past it to a text editor, I see 1.1750601 so I think the display rounds up to 1.180.
Just to be clear, Calc VET should block LTFTs. Since I'm running Calc VET with a WBOS, why do you think after applying VET results the car ran so bad?
OK, changed back display properties back to AFR. If I set all fields 1.75 they default to 1.80. Is that normal?
Ok, does this mean there is a problem with the O2s? or is this a configuration issue?
Two months ago, I was getting P0133 and P0153. I switched out my front O2s for bosch 13111 and the problem...
Yes. The short log represents the pre Vet tune. The car ran rich after applying the Calc Vet results but I did not log that run. I immediatly went back to the old tune.
Changed properties to display EQ Ratio and set B3618 to 0.85
I wasn't aware of the need to disable fuel trims. I read the Calc VET tutorial and summary notes and did not see that step.
Are fuel trims disabled by setting B4205 to something like 140 degrees...
I checked the plugs and wires, and everything looks good.
I completed a Calc VET but the results made the car run very rough. I then tried applying only the MAF table and the car idled in the 12s...
What areas of the MAF table seem low?
MAF Plumbing.
22268
Yes, the MAF was corrected via my last Calv Vet.
Do you recommend running another Calc Vet or can I manually raise some of the MAF table areas?
I used the results of Calc Vet and blended both MAF and VE tables. I use a WBOS for the AFR reference.
My old VE table is probably right. Calc Vet produced it. I never saw the benefits of the...

I set B0120 back to 4000.
I see. I was not aware I was running MAF only, that was not my intention.
I just checked my tune and found B0120 set to 400. I think I did not set B0120 back to 4000 after my last Calc Vet.
