Can someone take a look at a log for me PLEASE

[bikealarmblair]

Hi I'm new(ish) here & to EFi Live I've logged a couple of 3rd gear runs & roll downs but don't really know if all is well or not...

In my BMW E46 coupe I have

2004 gen 3 Ls1 V8 5.7 with a cam (215/230 .629/.592 117 LSA) everything else apart from hand made headers, no cats is standard.

Thanks Blair (UK)

Hi Blair,

Replace the O2Sxxx pids with LONGFTx, HO2Sx1 (where x is 1 or 2)... do you have front O2 sensors...?

Also add the pids EQIVRATIO, DYNCLYAIR, DYNAIR.

I see:
- you're spinning to 7100 rpm (is the valvetrain suitable for this...?) and bouncing off the rev limiter,
- a small amount of knock retard at 6600/6800 rpm, it probably is mechanical noise,
- MAP drops from 98kPa to 90kPa during WOT, this indicates your filter/duct/MAF are restricting flow as RPM increases,
- MAF has a problem with airflow at 6800 RPM.

Cool swap :cheers:

[bikealarmblair]

Do we have a build/car section here??

Valvetrain should be ok updated springs & pushrods.
What is WOT? Is there a list that explains what all the abrivations are?
I have front O2 sensors not rear.
I'll try & add those pids

Thanks

Try this forum subsection: Conversions-Aftermarket-Parts (http://forum.efilive.com/forumdisplay.php?77-Conversions-Aftermarket-Parts)

WOT = wide open throttle

Hi again I've been busy... I have had the std throttle body ported fitted a bigger LS2 MAF I've changed the PID's but 'think' I either have to many or I've removed the MAP PID....

Edit cause I'm dumb!

It pulls much cleaner at the bottom end & is a lot sharper too, at higher revs it doesn't feel happy

[bikealarmblair]

Anyone got a bit of time to point me in the right direction?

[joecar]

Replace the pid HO2S12 with HO2S21 (i.e. so you have both front HO2S pids HO2S11 and HO2S21).

You don't need the MAPBOOST pid.

If you reduce the pid channel count to 24 or less (see bottom of PIDs and Data tabs), the sampling rate will go up to 10 samples/second.

DYNCYLAIR_DMA would be interesting, you coult trade off AFR for this.


From 6700 and up MAF seems to oscillate and flatten out, I wonder if i's due to the intake duct.

DYNAIR and MAF diverging indicate that MAF and VE tables can be corrected (especially if MAF duct is different than original application).

LTFT's are not the same, but they are close to each other.

Commanded PE (power enrichment) is maybe too rich, but can't tell without wideband lambda. Do you have wideband lambda sensor...?

I see some Knock Retard, I can't tell if it's real or picked up noise (can you hear it knocking...?).

I think the intake is decent it's a large piper cross filter mounted in the front bumper which has a direct air supply.

I do have a wideband but can't work out how to connect it (innovate lm1?)

It's not revving cleanly you can feel it holding back above 5k

How do I get my pid file onto the v2 module?

Thanks
Blair

See here:

Cheers lets see how much of a mess I can make of this ;)

FYI dyno graph from the other day I was intending to log it but it didn't work for some reason.

[bikealarmblair]

1191311914think I've got a couple of quick logs....

[bikealarmblair]

Do I need to tell the PCM that I have fitted a later/bigger MAF?

[maudyZ28]

hey dude, nice to read about your swap,it's pretty cool :D

Haven't had time to look at your logs yet but will try tonight.

Something really doesn't seem right, the dyno suggests the car peaking at 5000 rpm then dropping off, did YOU do the cam change??? ie are you sure it has been done

You'd need to get the LM1 WB hooked up and do a full MAF and full VE calibration independantely to ensure airflows/volumetric efficiencies are correct such that the car knows how much fuel to add, you can fudge this but generally it is NOT good practice. Shame you didn't get the dyno AFR back either to check what was going on.

Are you really spinning the motor upto 6500 rpm + all the time?? Seriously the rod bolts will not be happy, and I hope you've got hardened push rods, uprated springs etc?

[bikealarmblair]

I didn't fit the cam Craig did & yeah I'm sure unless he managed to slip it in his pocket ;)
http://i1196.photobucket.com/albums/aa404/Blair_McWilliam/My%20BMW%20LS1%20V8%20Conversion/th_4e0dc185.jpg (http://s1196.photobucket.com/albums/aa404/Blair_McWilliam/My%20BMW%20LS1%20V8%20Conversion/?action=view&current=4e0dc185.jpg)

All the springs/rods/ etc have been upgraded to take the extra revs, one of the guys here has been revving his to 7400 without issue for the last 4 years.

I'm not reading much into the dyno graph I've ordered the lead for my wideband so as soon as that gets here I'll start getting it dialed in.

Glad you like my car :)

[maudyZ28]

yeah defo do, cool swap.

sorry didn't mean to sound harsh or anything, just wanted to check. I'm only spinning mine to 6500 with hardened push rods, dual springs, ti retainers but still on stock bottom end conrod bolts and on 99 camaro LS1 they aint happy after that, plus my auto box is under enough strain as it is.

yeah, don't bother about dyno for numbers, i just mean to say that you can obviously see you're dropping power after 5000+

Did Craig in Birmingham do the swap, the dude who built the twin tube RX7? if i can remember right??

Have you tuned motor yourself? Or had it done at all? If you want a bit of a heads up have a look at my tunes here http://forum.efilive.com/showthread.php?17132-Lots-of-Knock-is-it-real just to compare some of the changes. I running 228/228 0.588/0.588 TSP on 112 LSA 110 ICL

With your log, you still need HO2S11 sensor NOT HO2S12 (ie 1st no is for bank, 2nd number is for sensor, 1 is front, 2 are rear o2)
with the o2 you have logged it NEVER maxes when your at WOT, this is NOT good. Is it working fine? if so then the car might not be fueling right, O2 should be at 900 mv flat when you are at WOT

You are getting a lot of knock, false or real,
but O2 if fine shows you are not richening mix up and the timing is way down so shouldn't be pre detonating really.

your current tune may be of help, see what is going on?

[joecar]

Do I need to tell the PCM that I have fitted a later/bigger MAF?You have to correct the MAF table B5001 (using wideband correction factor)...

changing the MAF sensor and/or duct alters the response freq-vs-airflow.

[joecar]

Yes, as Maudy said, rule of thumb is HO2S11 and HO2S21 (front sensor on each bank), should be above 900mV on a WOT load pull (~920mV)...

but don't rely on this, use a wideband to confirm sufficient enrichment.

[bikealarmblair]

Maudy not harsh at all :)

Yes Craig did the conversion for me I do all the electrical stuff for him, part of the 'deal' for doing my car was me re-wiring his rx7 which is now an LS3 bored/stroked to 7.1l with twin T35 turbos......

http://i335.photobucket.com/albums/m468/tinker--27/519ffa8b.jpg

I've not touched the tune at all yet, I'm waiting for a lead to connect my wideband to the V2 before I start messing with it

Joe do I need to wait for my wideband to do that?

Thanks guys

[joecar]

Yes, wideband is required for doing WOT VE/MAF corrections.

[bikealarmblair]

Thanks Joe

[maudyZ28]

haha small world, on international forum and I know Craig (through email contact) who did your swap. nice :D

Does your car drive well apart from WOT, like I say i'm not sure what is going on at WOT as your O2 are not maxing out. If you take a look at some of the logs I posted on that link to my tune above then you'll see what I mean. With having cam done you need WB to correct MAF and VE.

Do you have access to a dyno permanantly? Wouldn't mind helping with the tuning, think your about 2 hours away from me?

[bikealarmblair]

We only have a bike dyno don't think the car will fit on it ;)

It drives great until about 5k, I'm just playing with chassis until the wideband lead arrives & then I'll do some logs and I'm hoping I can spend some time with Richard from EFI live to learn a few tips n tricks first hand.

[maudyZ28]

cool, well let me know if I can help or if a meet up would be possible. Would be good to come down and meet Richard too, got EFIlive off him and had a few tips via email too but would be good to all chat in person? Why do all you guys live down south hahahahah :hihi:

[bikealarmblair]

My lead has turned up so I've done a quick couple of logs, can you guys check I'm logging the things before I get started?
I think one of the O2 sensor's is faulty so I'm going to swap them over to see if it's a sensor of wiring issue

Blair

[bikealarmblair]

I've swapped the O2 sensor & they seem ok to me now, I've also fitted the wideband sensor in the mid section instead of the back box.

So as long as it's all logging ok I'm ready to begin tuning....:cucumber:

I've been reading the auto VE tutorial (from the help section on 7.5 scan) & it seems that it's a MAFless tune is this correct or am I reading it wrong?
The battery on my laptop is rubbish is there a way to do it without needing the laptop in the car?

Thanks Blair

[joecar]

Yes, AutoVE corrects the VE table in MAF-less and Open Loop mode...

when you are happy with your VE table, you then enable the MAF, set the dynamic threshold (B0120) low, remain in OL, and do "AutoMAF" to correct the MAF table.

Maybe I should have read the above first....

Followed the tutorial to the end uploaded the tuned file & the car wouldn't run.... re-loaded the original file & drove home!

The only part worth noting is many of pids were 'not valid'

[slows10]

Not sure where you went wrong. But it probably will not run with the main ve table like that. Try the links joecar posted. A new twist on calc ve table. check out the summary notes

[slows10]

Also make sure when you connect to scan tool try validate pids.

[joecar]

If you have a V2, then download/install [run the .exe] the V7 and V8 software from the download page at www.efilive.com (http://www.efilive.com)

and then program firmware 2.07.22 [comes with the V8 software] into your V2.

[joecar]

Before pasting/multiplying the BEN map, take a close look at:
- the units of the MAP axis (should be in kPa same as VE table),
- the units of the data (must match the VE table),
- the values of the data (BEN values should be close to 1).

In the scantool, on the PIDs tab, set MAP to Metric (do this by rightclicking on MAP and selecting Metric).

[bikealarmblair]

I gave up in the end & got a local tuner ( www.protuner.co.uk ) to map it for me on his Dyno car drives really well & I've done a few thousand miles in it & not too much has broken :mrgreen:

Greg (protuner) did the tune MAFless after speaking to Richard (Ringram) who gave a lot of pointers as Greg hadn't used EFILive before one of the things I'd like to start working on is the lean mode to make it more economical on long runs.

I've attached the tune & some logs
