Could any of this be related? I only use 91 from chevron/76.

I'm assuming you still have your stock cats on... It could be your front o2 sensors...

Just installed new plugs after getting consistent misfires on cylinder 5 and 3... Running smooth now... please review and give feedback.. Thanks!

Ok I'm actually having Offset Motorwerks look at the car again and they'll look into it. Here's a couple more logs of sixth gear I did, these pulls felt quite rough but no misfire. It almost seems like the misfires happen when I hold my foot at half-throttle rather than full. One of these runs is like that and it felt the roughest.

Have the tech look at your front o2 bank 2 sensor (pre-cat)... you are running very lean in bank 2 and my guess would be the o2 sensor is shot. Would make sense with the milage in your car since they can go out close to 100k.

I believe this is also consistent with the codes you are getting which point to front o2 sensors.

I wouldn't push the car hard until it gets fixed.

Flashed to 6.1 did a few pulls before logging what do you guys think. I have stock Dp's on for the moment (inspection) so keep that in mind.

Clean... get some DCIs after inspection since it looks like you are losing a bit of boost up top on the stock intake.

Hi experts,

Could somebody have a look at this log?

http://datazap.me/u/rismo/log-146748...og=1&data=4-22

Car seems to have a challenge to reach boost target...

102 ron race gas
103 ron MHD v6.1 map
DCT
FBO etc etc
Procede in map0 (Clearcan etc off)

Boost solenoids or are my turbo's shot? Or could it be a boost leak? When boost is reached it seems to hold so, im doubting about a boost leak....

For some reason I cannot access the link (on my iphone). What is your mileage?

It was not set to public. :-) Now it is...

The turbo's have done 90k miles...

wren57 · 07-02-2016, 04:06 PM

Boost leak, tired 112k mile turbos, or tired boost solenoids? I've checked for a boost leak multiple times and can't find anything.

http://datazap.me/u/wren57/log-14674...12&tmax=385.05

FBO-inlets, s2+ v6 tune.

first off... WDE...alumni and raised in the gump over hear. Weird you're having lost of boost at that milage... I'm at 110k.

d8rknight · 07-02-2016, 05:41 PM

so after 3 injectors, valve cover gasket and 3 coils being replaced... I've been able to run OTS St 2 map 93 pump. Have a look folks. http://datazap.me/u/d8rknight/93-mhd-pump-v6

You shouldn't run that map. you have a lot of corrections in each cylinder.
#2 cylinder looked OKish. also your IAT are way to high. you need a better intercooler.

He has stage 2+ turbos, thats low boost for him.

Double check you vacuum side of things, might be a vacuum leak or a boost solenoid.

Should've clarified, stage2+ tune, on stock turbos. Either way I think it's low boost, no?

Ton of timing corrections..how are your intake valves, plugs? also lpfp in the danger zone..

Brand new, and just walnut blasted. Also just replaced all vac lines. It was a very humid 100 degrees out.

Have you reset adaptations recently? If not I'd reset them and do 3-4 pulls then grab a log

All the lines were taken off and tightened back up; the 30FF hasn't fired since.

I was able to get a good 2nd gear pull and most of a 3rd gear pull before someone pulled out in front of me. It definitely appears that I'm not going to where I'd expect boost wise. Does anything look odd in this log?

Can someone throw this guy a bone, so he stops texting me complaining that no one replies?
