clint, are the idc numbers accurate? they seem to be but i was reviewing logs from tuning today and noticed a spot where the car hit 103% idc :eek3: at redline. i'm going to adjust downward tomorrow but wanted to check with you and get your feedback. thanks, this thing is fawkin amazing :bigthumb:

 

[chansigril]

No fudge factor with MMCd IDC numbers. If you see something +/- 100% you are out of fuel. (Value can go slightly over 100% due to small skew in time between RPM / INJP readings.)



Clint

that's what i was worried about. alright, well thanks for the confirmation, time to re-tune a little

 

[chansigril]

Well everything seems to be working fine on my car i know i am pushing the limits of the stock fuel at 15psi.

apparently i am pushing the limits of the 450cc injectors at 15psi :eek3:

interestingly, i am getting zero knock

i'm thinking that perhaps some of these idc numbers are a little off. if you have 110%+ idc does your wideband o2 show you running lean? my wideband isn't working right now, but my narrowbands don't really dip below .91v unless i'm in third or fourth, then they dip to .89v. does your egt start to climb when you see this high idc?

re: o2 sensor not cycling properly, my rear went at 110k miles. it was going due to my rear turbo leaking oil... after the turbo blew apart it wasn't doing so hot :lol3: new o2 sensor and they're both doing fine

 

[chansigril]

that is a good assumption there is no way to tell load specifically that i am aware of.

one question, why aren't you logging both o2 sensors

 

[chansigril]

Fed spec NA's only have 1 o2. I think they changed to 2 in 94+ when all were considered cali spec?? not positive on that.

Yea after my first datalogs I bought the o2 hoping that was the problem(and with almost 160k I didn't mind buying a new one anyhow.

My ecu is good, mas is good, and have been told I need to check the FPR... if anyone else has ideas let me know!!!!!!

aha, my 94 na had two so i figured all na had two not cali spec tho, i believe cali spec had three, mebbe even four :eek3:

i doubt the problem is your fpr, particularly on a na. anything is possible but i'd be mighty surprised. seems like a good reason to buy a wideband o2 :lol3: alright not really. i'd check the wire harness, connections, possibly ohm out the wiring if you can find specs for it or can test it somehow.

ive considered the WB and maybe a fuel controller. I just wish I knew which way to throw the little amount of my I have at the car so it gets better! lol

Car always breaks down near the holidays!! ugh..

start with the tuning products then add go fast goodies wbo2 sensor ftw mebbe for christmas?

i had an afc once for my na, i saw minimal gains from it even after some dyno tuning. money was better spent on the underdrive pulley and lightweight flywheel, as well as suspension and poly motor mounts for traction. even better was money spent on n2o, but that gets pricey quickly :lol3: i would not recommend an afc unless you are planning to run larger injectors for n2o or something similiar... i did not need to upgrade my injectors to run a 60 shot of n2o btw

ok, I used the bag method, and was putting the air into intake, and the only leak(or biggest leak I could tell was coming from the connection where the VICS(whatever its called on NA's) mounts on the passanger side of the plenum. I cannot tighten it as its meant to spin. I took the motor off the other side and it appears to have been eating away at the gear. I wouldn't mind totally getting rid of that system but would have to find a way to plug it all up. and I would end up loosing a little hp.

It would take aprox 12 seconds to let 20psi out. Is that a big enough of a leak to be what you think it is??

do not remove your vics, you will be very unhappy. do a little searching around and you'll see what other folks have experienced by doing this, more than losing a little horsepower (well, losing torque actually )

as to the leak, that is a very good idea clint is talking about, i should have noticed some of the signs as well but didn't really examine your log that closely. 20 psi over 12 sec is a nice little leak, what pressure did you take the intake to?

 

[chansigril]

I don't think the VICS is working properly because it looks like the teeth on the plastic gear are all stripped. I guess I could try to find another plenum.

I only took the psi up to 20(thats where I set the regulator at)

i would def replace your plenum.

i also agree with clint that the leak you have is a problem but not the problem.

silicone... i prob wouldn't silicone it, sorry.

is anyone using the lm-1, scanmaster and mmcd? the reason i ask is i am using the analog 1 input on the scanmaster for my wbo2 and would like to log it with mmcd.

mebbe i missed it, i've been searching this thread for 15 minutes now. many references to the lm-1 and egrt input, but i went a different route and incorporated the scanmaster in there. i was playing around with the mmcd options today and could not get it working, i really need to log my wbo2 value and tho i love the scanmaster, mmcd is the definitive way to log and an ideal way to tune.

any help is appreciated, i apologize if this was covered earlier but i couldn't find it. a bit of mellon yapping about his lm-1 and egrt, smoothing out his signal etc but no helpful scanmaster references

thanks in advance

Configure dSb (data Substitution battery) to 1

Then the battery voltage reading on MMCd will actually be your AFR.

Bob

bob, instead of configuring the battery voltage, i went in and changed the os parameter to analog 1 to constantly display my afr. i saw where i could configure the battery voltage instead but thought the easiest way was changing the os.

i'm going to go look at my manual here in a minute and see if i can muddle through this, i'll check back with any problems or q's.

on second thought, i suppose i could set the dsb to 1 and leave the os parameter where it is as, allowing the scanmaster to still display the wbo2 and mmcd to see it as battery voltage

hrm *hits jeff's site to check scanmaster manual*

 

[chansigril]

If you are going to log wideband with mmcd download the source and change the scaling for wb02 and compile.

you can also change the... battery voltage input? i can't recall off the top of my head and my palm is out of juice, pretty sure it's battery voltage input to allow the wideband signal
