Exactly what codes do you get when it goes into limp mode?

Yes STFT goes higher than AFR, that should not be happening from my understanding.

[Shinikami]

Thank you for your reply.
The codes are 2E68 (knock sensor on Bank 1) and 3100 (disabled boost) as a safety measure.
These codes never pop on me on WOT, however.

Anyone have a quick look at this please n also tell me what fuel mode 15 is please as goes into this before missfires starts on bank 2
Have replaced injectors with index 12 also PR coils and 2 stage colder plugs now
Just clutch n flywheel to go, am looking for my spec flywheel

Which fuel are you running?

Doesn't look like injector related,

[Shinikami]

Solely 98 RON (93 Octane/AKI).

You could run INPA to check how injectors running, to help rule them out. Would also be a good idea to check O2 sensors in Inpa whilst your at it.

Someone more knowledgeable can chime in, can stft levels going above afr cause knock?

Car has super big hesitation on light throttle or/and no load at 1800rpm. Index 12 injectors, oem coils, oem plugs, walnut blast, boost solenoids. Log is a 3rd gear pull where you can't feel the hesitation.

Have you tried cleaning vanos Solenoids to see if they make a difference?

I did a couple of 3rd gear pulls after installing my Stage 2+ Walbro 450 LPFP, and switching over to the V5 Stage 2+ E40 MHD tune.

The car pulls crazy hard, and it's nice and smooth. But I did notice a few things in the log that concerned me.

The first is that towards the end of the pull, the boost just falls off like it can't keep up with the boost target. The WGDC gets pretty high, around 70%+. Are my turbos just at their limits as far as what they can flow?

The other things is that the LPFP started jumping all over the place.....between 60-90psi. Could it be an issue with the LPFP sensor? This run was done on 1/2 tank of fuel.

Thoughts?

Did you have these issues with V7.1?

If not, then it's most likely map related.

I have not tried the V7 E40 map. I guess I will, and see how it compares.

I do know that when I first put the new stage 2 LPFP in, I was running the V7 stage 2+ 93oct tube....and the LPFP pressure stayed nice and smooth....right around 80psi during the entire run.

It might not be a bad idea to try the e40 V7 tune and log it.....

FBO, PS2 turbos, PI, full e85, Stage 3 LPFP, etc.

Hoping to make closer to 700WHP. Could the timing be a factor? Any info is appreciated.

You're getting some massive timing corrections.

[rev210]

Trying to figure out some timing corrections putting a lid on things.. thoughts are possibly injectors(please no) plug or coils. Car pulls nicely but, its pulling timing. Pure st2 , flex , stg3 fuel pump ,PI and all the rest.

The Dyno log does have some serious timing corrections. Here are two street logs from 4th gear. Same tune and setup.

What did Motiv say about the timing corrections?

[thormessiah]

Hello all, here is a single log I was able to get today after weeks of being down. The car was on 11 gallons of 93 and 5 gallons of e85, running a custom e30 tune by wedge. I have been getting a few misfire codes of late which I managed to fix by installing new postcat sensors and brand new bosch plugs. However I notice the car seems to hiccup/stumble under high load low rpm situations, or in wot at very high gears. The only codes are some shadow codes which are

2FDB - CRANKSHAFT SENSOR SIGNAL PLAUSIBLE
30ED — DME SUPERKNOCKING CYLINDER 1

Log : https://datazap.me/u/volfwaley/log-1602307169?log=0&data=3-20

Thanks in advance

Hi guys I'd love some help with my first data log.

MHD Stage 1+ 91oct V9
7.5" stepped FMIC
New coils and plugs

https://datazap.me/u/dman335/06-10-2...-6-7-8-9-10-20

Boost target, WGDC, IAT, LPFP, HPFP, STFT and Lambda all seemed fine.

Can someone help me understand these:

Timing Corrections (Individual Cylinders):
C1- Post shift correction max at -5
C2- Start of log max -2.3. Post shift max -3
C3- No corrections
C4- Start of log max -3
C5- Start of log max -2.7
C6- Start of log max -2.7
Are these bad?


Ignition (Crank): Two sharp drops. First drop from 4.5 to -14.5 at 5800rpm just after the gear change. Second drop from -1 to -10 when ending WOT. What does this suggest?

Looks fine mate, post shift timing corrections are normal and so are timing corrections at low loads. Ignition crank should be OK too.

Post shift timing corrections can probably be reduced with a Transmission tune if your car is a Auto, like Rod Sutphin does/XHP depends on TCU

Would highly recommend XHP stage 3, if your on ZF

I wouldn't worry about it, your log looks fine.

Which fuel are you running, post says 91 oct but log says 98 (assuming Ron?)

Awesome, I appreciate the help. I'm planning on flashing the XHP tune soon, so it will be interesting to see how much those corrections change. I was mainly worried because I had read that the corrections shouldn't be more than 3 degrees.

Yes I use 98ron Aussie fuel but I'm running a 91 OCT map because apparently our fuel is poorer quality down here (due to a lack of 10% ethanol in it)

No worries,

If you can get hold of 93oct fuel, that would improve timing corrections and give you more power.

Yeah, 91oct is pretty poor fuel.

If not for anything else, XHP flash removing torque limiters and increasing clamping pressure makes a huge difference on a Tuned N54,

Pushing 2 bar! Badass. Is the block built?
