by the way, i noticed my boost target dropped after fmic install, what could be the reason for that?

It's building boost and drops when on target.
Looks just fine to me

No expert but I think it's targeting 1 psi less boost
because the v7 is load based, and load is on request.

I noticed it went to 54 (at the lowest point) and looked around on the forums. I read as long as it doesn't go below 50 it's considered alright? I don't know if this is accurate.

I had a second log from that day and it exhibits the same numbers.

Thanks

Thanks for the reply, learned something new again.
So in other words, load target is achieved in lower boost levels after the new fmic was installed, would boost based v6 maps benefit more from my new intercooler?

Heres my log... not to sure what to look for let me know what you guys see.... thanks

Not sure what else to look at. It doesnt matter if I'm running my E40 tune or E60 tune. Any other ideas what to look at? I was REALLY happy with my E60 until this all started happening and I'm starting to feel like the car cant handle E60 but I dont know why all of a sudden this would be an issue.

Welcome to the club. I have had the same issue for months and can't figure it out. Your fuel pressure looks fine to me. Your a little lean in the beginning, but look fine the rest of the pull. For me, I have mid-range shudder, how about you?

agree... takes 300 rpm to spool up to target... looks healthy to me. i didn't look at anything else though.

I did some testing last night after resetting adaptations and my E40 map works fine, once again, with E40 or E60 in the tank and now only my E60 map has 'shudders' regardless of fueling. I've tried E40, E55, E60, E62, E70, and E72 and they all have the same 'shudder' feeling

Wondering if my plugs not being gaped right could be a culprit. I had a misfire issue in cyl 2 and 6 and they were gaped like all the other plugs to .21. After pulling and checking the plugs 5 times I got pissed and made plug #2 .19 and plug #6 .25... maybe .25 is too wide on WOT?

I left them that way because my misfire and rough start issues went away

Someone fancy having a look at my logs please? Running the MHD STAGE 1+ fmic but without the fmic just wanting to see how it looks. http://datazap.me/u/pullar33396/3rd-...20-21-22-23-24

You could flash the v6, check your logs, and go with the one you like the most.
I would stay with the v7, your log looks clean and v7 is the best ots map imo

Lpfp is dropping below 50 and something weird is going on with afr and fuel trims, do you get any codes?

Ever since I installed down pipes I get the heater circuit codes for all 4 sensors... There is a fuse that keeps blowing everytime I replace it...

You should take a look at that

Looks OK to me. Boost matches target. AFR good. Timing OK. One small throttle closure to drop boost to target. Looks like you were 'easing' on the throttle until ~3000 RPM, which caused a large gap between boost target and actual, but it maintained target pretty well after that.

Thanks very much, yeah it was my first time logging so didn't know too much about what to do but I'm pretty confident now for the next log. Thanks again

Can someone please take a look at my logs

I have no idea why my car is boosting so low on 7.1 stage 2 with DPs. It seems to max out at 13.6 psi.
Furthermore, the targets are very low as well? I thought Stage 2 was meant to be 16-18psi?

Load based map, load is on request, it takes 13 psi to get there. Log 1 looks clean

Sorry I don't quite understand. Was I not requesting full load even though my acceleration pedal was at 99.6%?

EDIT: just had a read of http://stratifiedauto.com/blog/load-...-based-tuning/

It looks like it might be due to my ambient temps and what not that my car wasn't boosting as hard as I had thought? Maybe everything is normal?

Yes its normal, once load target is achieved ecu drops your boost target because more boost isnt required (for example: intake air temperature/ambient temp affects how easily load target is achieved).. you can try v6 maps because they are boost based and load target isnt interfering your boost levels..Sure v7 maps are more refined,smoother and consistent, but there is more power left to the table in cases like this imo..

Btw: Check your afr readings.. If im correct, you might have leaking injector on bank 1..

Can someone please take a look at my log for me. tried the stage 1+fmic ots tune and it ran fine but I'm leary about it. 3rd-mid 4th run.

Mods are just DCI.

Hmm I did notice the afr difference when letting off.
All my injectors were changed to index 12 about 8 months ago...
